Bee Movie Script - Dialogue Transcript
|svenskt_namn=
Voila! Finally, the Bee Movie script is here for all you fans of the Jerry Seinfeld animated movie. This puppy is a transcript that was painstakingly transcribed using the screenplay and/or viewings of the movie to get the dialogue. I know, I know, I still need to get the cast names in there and all that jazz, so if you have any corrections, feel free to drop me a line. At least you'll have some Bee Movie quotes (or even a monologue or two) to annoy your coworkers with in the meantime, right?

'''Bitcoin''' (av "[[bit]]" och engelska "''coin''" = [[mynt]]) är en implementation av [[kryptovaluta]], en digital valuta, skapad 2009 av Satoshi Nakamoto (troligtvis en [[pseudonym]]), vars huvudsyfte är att möjliggöra [[e-handel|betalningar över Internet]] direkt mellan användare utan någon inblandning från tredje part.<ref name="whitepaper">

Till skillnad från många andra valutor förlitar sig inte Bitcoin på någon central utfärdare i form av exempelvis en [[centralbank]], vilket skyddar mot politisk påverkan och monopolliknande betalsystem. För att upprätthålla säkerhet och sekretess förlitar sig Bitcoin på [[kryptografi]] och använder sig av en distribuerad databas utspridd över de noder som utgör P2P-nätverket för att journalföra transaktioner. Detta syftar även till att exempelvis säkerställa att valutan endast kan spenderas av dess ägare samt ''oåterkalleligen'' försvinner från nämnda ägares digitala "plånbok" och därmed bara kan spenderas en gång.<ref name=whitepaper/>


Bitcoins design tillåter mer eller mindre anonymt ägande och överförande av värden genom P2P-nätverket. Varje användares bitcoin sparas i en ''plånboksfil'' tillsammans med ett godtyckligt antal ''bitcoinadresser''. Plånboksfilen kan sparas på användarens dator eller hos en tredje part som erbjuder en sådan tjänst. I båda fallen kan bitcoin skickas över Internet till vem som helst med en bitcoinadress. Bitcoins P2P-topologi och avsaknad av central administration gör det omöjligt för exempelvis myndigheter att artificiellt manipulera värdet av bitcoin eller framkalla [[inflation#Förklaringar till inflation (penningmängd)|inflation]] genom att producera fler av dem.

==Teknisk bakgrund==
Tekniken bakom Bitcoin beskrevs först i Satoshi Nakamotos [[Vitbok (skrift)|vitbok]] från 2009<ref name="whitepaper" />. Den bygger på två andra förslag på alternativa elektroniska valutor: Wei Dais förslag b-money och Nick Szabos förslag Bitgold.<ref name=whitepaper/>
The bee, of course, flies anyway


Bitcoin är en P2P-valuta, dvs ett [[P2P-nätverk]] håller reda på alla transaktioner i en distribuerad databas. Det finns ingen central server som håller reda på dem eller avgör vilka som är giltiga. Varje deltagare (nod) i P2P-nätverket lagrar transaktionerna, och kan gå in i eller lämna P2P-nätverket utan att skapa problem.
because bees don't care
what humans think is impossible.


Tidigare förslag på P2P-valutor led av [[dubbelspenderingsproblemet]] (eng: ''double spending problem''), dvs att samma pengar kunde överföras till två olika ställen, och att nätverket då måste ha en metod för att avgöra vilken transaktion som var giltig. Satoshi Nakamoto löste problemet med hjälp av en så kallad [[blockkedja]] (eng: ''block chain''). Varje transaktion lagras i ett block med data, och alla block hänger ihop i en följd (kedja). Om det skulle skapas två "konkurrerande" block (två block med samma föregångare i kedjan), accepterar noderna det block som majoriteten av deras grannar har accepterat, och bygger nästa block i kedjan på detta. Om det sker en förgrening av kedjan, fattar nätverket alltså ett beslut om vilken gren som är giltig. (och därmed vilken transaktion som är giltig). Beslutet sprids snabbt genom P2P-nätverket, vilket gör det praktiskt omöjligt att ändra. För att göra det svårare för en angripare att tillverka block som stöder deras egen gren av blockkedjan, används en ''distribuerad tidserver'' och tidskrävande beräkningar för att skapa ett block, så kallat [[bevis-på-arbete]] (eng: ''proof-of-work'').
Yellow, black. Yellow, black.
Yellow, black. Yellow, black.


Transaktionerna använder [[asymmetrisk kryptering]] (mer specifikt [[ECDSA]]) och är publika. Historiken över alla transaktioner måste lagras i databasen och för att minska kravet på lagringsutrymme används ett [[Merkle-träd]].<ref name="whitepaper" />
Ooh, black and yellow!
Let's shake it up a little.


===Plånboksfilen===
Alla som deltar i Bitcoin-nätverket har en plånboksfil (<code>wallet.dat</code>) som innehåller, utöver antalet bitcoin knutna till den plånboken, ett godtyckligt antal kryptografiska [[Asymmetrisk kryptering|nyckelpar]]. De publika nycklarna utgör bitcoin-adresserna och agerar som sändare eller mottagare för alla transaktioner. Deras motsvarande privata nycklar auktoriserar betalningar från endast den användaren. Adresserna innehåller ingen information om dess ägare och är generellt sett anonyma.<ref name="lwn">

Bitcoin-användare kan ha flera adresser och generera nya obehindrat, då genererandet av nya adresser kräver förhållandevis lite beräkningar och inte kräver någon kontakt med resten av nätverket.


Plånboksfilen lagras direkt på användarens hårddisk. Skulle användaren råka radera filen försvinner de bitcoin och adresser som associerades med just den plånboken för gott.<ref name=lwn/> Därför uppmanas Bitcoin-användare att säkerhetskopiera plånboksfilen regelbundet.<ref name="faq">{{webbref

En lättviktsklient verifierar inte transaktioner utan förlitar sig på en fullständig klient som den ansluter sig till. Bitcoin Core är den ursprungliga klienten som används i Bitcoin-nätverket för att lagra en fullständig kopia av alla transaktioner.<ref>{{Tidningsref|rubrik=Bitcoin Plånböcker - Hur du skyddar dina Bitcoin {{!}} CryptoRunner|url=https://cryptorunner.com/sv/bitcoin-planbocker/|tidning=CryptoRunner Sverige|hämtdatum=2018-01-09|språk=sv-SE}}</ref>


=== Transaktioner ===
Bitcoin innehåller dess nuvarande ägares publika nyckel (bitcoin-adress). När användare ''A'' överför en summa till användare ''B'' ger ''A'' upp sitt ägande genom att lägga till ''B'':s publika nyckel (bitcoin-adress) och signera de bitcoin som ska överföras med sin egen privata nyckel.<ref name="transactions">{{webbref

}}</ref> ''A'' sänder sedan dessa bitcoin i ett meddelande, ''transaktionen'', till P2P-nätverket. Resten av noderna i nätverket validerar sedan de kryptografiska signaturerna och summan av transaktionen innan de accepterar den.


=== Blockkedjan ===
[[File:Blockchain.svg|102px|thumb|right|Huvudkedjan (svart) består av den längsta kedja av block från genesisblocket (grönt) till det nuvarande blocket. Föräldralösa block (lila) existerar utanför huvudkedjan.]]
Hello?


Data lagras permanent i Bitcoinnätverket i s.k. ''block''. Dessa block formar en kedja och ett block innehåller de senast utförda transaktionerna samt det föregående blockets [[hash-funktion|hash]]. En transaktion går inte igenom förrän blocket den tillhör har blivit tillagt i kedjan.<ref name="block">{{webbref

De noder i nätverket som är beredda att bistå med beräkningskraft samlar alla obekräftade transaktioner de känner till i kandidatblock. Sedan försöker de skapa en kryptografisk hash för kandidat-blocket med vissa egenskaper, något som kräver en förutsägbar mängd [[trial and error]]. När en nod slutligen lyckas med det annonserar den det till resten av nätverket. De noder som tar emot det nya blocket validerar det sedan innan de lägger till det i block-kedjan. Blocket sägs nu vara ''löst''.
- Oan you believe this is happening?
- I can't. I'll pick you up.

=== Bryta bitcoin ===
När en nod som valt att bidra med beräkningskraft till nätverket lyckats lösa ett block och detta kandidatblock har lagts till i blockkedjan, erhåller noden en belöning. Det här är den mekanism som gör att nya bitcoin tillkommer i Bitcoin-nätverket, och mekanismen kallas "brytning" (jfr [[Guldbrytning]]). Användare kan bidra med beräkningskraft genom att antingen aktivera brytningsfunktionen i den officiella mjukvaran eller genom att använda mjukvara från tredje part. I det senare fallet utförs beräkningarna ofta på användarens [[GPU (datorteknik)|GPU]] för ökad effektivitet.<ref name="diablo">

</ref> Blockbelöningen var ursprungligen 50 bitcoin per block och den halveras efter varje 210 000 block, vilket motsvarar ungefär vart 4:e år. I februari 2018 var blockbelöningen 12,5 bitcoin per nytt block, och den kommer över tiden att minska ner till noll. På så vis kommer ett maximalt antal på ca 21 miljoner bitcoin skapas. Det beräknas att 80 % av alla bitcoin kommer vara skapade 2018.<ref>{{Tidningsref|rubrik=80% av alla Bitcoin är uppgrävda - Coinbuddy|url=https://coinbuddy.se/80-av-alla-bitcoin-ar-uppgravda/|tidning=Coinbuddy|datum=2017-02-01|hämtdatum=2017-02-09|språk=sv-SE}}</ref> För att upprätthålla en brytningstakt på ett nytt block i genomsnitt var tionde minut, justerar nätverket automatiskt svårighetsgraden{{förtydliga|datum=2018-02}} ungefär varannan vecka (efter var 2 016 block) för att ligga i linje med nätverkets totala beräkningskraft.


Eftersom mer än en nod tävlar om att lösa ett specifikt block och svårighetsgraden ständigt ökar har det blivit populärt med kollektiv brytning i så kallade "pooler". På så vis kan även användare som inte förfogar över så mycket beräkningskraft få en jämnare och mer förutsägbar inströmning av belöningar.<ref name="pool">

==== Transaktionsavgifter ====
Användare som vill göra en transaktion kan frivilligt välja att betala en transaktionsavgift. Transaktionsavgiften tillfaller den nod som lyckas lösa just det block som innehåller transaktionen. Detta gör att det blir mer attraktivt för noderna att försöka lösa block som innehåller transaktioner med avgift. Transaktioner där transaktionsavgift har betalats kommer följaktligen att prioriteras av noderna och processas därför oftast snabbare än övriga transaktioner.
Here's the graduate.
We're very proud of you, son.


När det inte längre går att [[Mynt | prägla]] nya bitcoin genom brytning förväntas möjligheten att lösa block för transaktionsavgifternas skull vara anledning nog för användare att bidra med beräkningskraft till nätverket. På så vis kan systemet ändå hållas igång.<ref name=whitepaper/>

== Ekonomiska aspekter ==

===Monetära skillnader===
[[Image:total bitcoins over time.png|thumb|right|238px|Totala penningmängden bitcoin över tid]]
- You got lint on your fuzz.
- Ow! That's me!


Bitcoin skiljer sig från traditionell [[fiatpengar|fiatvaluta]] i det avseendet att mängden kontanter ([[Penningmängd|M0]]) inte kan kontrolleras genom att en [[centralbank]] ger ut mer av, eller destruerar, kontanter. Det finns heller ingen centralbank som kontrollerar [[Penningmängd|penningmängden]] genom att justera [[Styrränta|styrräntan]]. Det finns en begränsad, kontrollerad ökning av kontantmängden hårdkodad i Bitcoin-mjukvaran som är känd och förutsägbar av alla parter i förväg.<ref name="whitepaper"/> Inflationen kan därför inte styras centralt.
- Wave to us! We'll be in row 118,000.
- Bye!


Transaktioner genomförs direkt mellan användare över nätverket utan att något finansiellt institut är inblandat. Den här typen av transaktioner innebär dock att det är omöjligt att reversera en transaktion. Bitcoin-klienten sänder transaktionen till noderna i dess omgivning som i sin tur propagerar den till resten av nätverket. Korrupta eller ogiltiga transaktioner nekas av ärliga klienter. Transaktioner är oftast gratis men en transaktionsavgift kan betalas för att noderna i nätverket ska prioritera just den transaktionen.<ref name="whitepaper"/>
Barry, I told you,
stop flying in the house!


Den totala mängden bitcoin ökar kontinuerligt men kommer aldrig att överstiga 21 miljoner i antal. Penningmängden växer enligt en [[geometrisk summa]] vart fjärde år; år 2013 kommer halva penningmängden ha blivit genererad och år 2017 kommer 3/4 ha blivit genererad o.s.v. Allteftersom det totala antalet närmar sig 21 miljoner kommer värdet av bitcoin successivt att uppleva pris[[deflation]] (en ökning i reellt värde) på grund av att inga nya bitcoin längre skapas. Bitcoin är dock delbara ner till åtta decimaler (vilket ger 2.1 x 10<sup>''15''</sup> enheter), vilket undgår de praktiska begränsningarna som deflation innebär.<ref name=lwn/> Istället för att förlita sig på incitamentet att tjäna pengar genom brytning förväntas noder under den här perioden förlita sig på sin förmåga att kompetitivt ta ut transaktionsavgifter för att genomföra transaktioner.<ref name="whitepaper"/>
- Hey, Adam.
- Hey, Barry.


===Utfall===
Möjliga scenarion där Bitcoin misslyckas inkluderar [[Devalvering|valutadevalvering]], en minskad användarbas, eller lagliga regleringar eller förbud av handel eller innehav. Det är inte säkert att det är möjligt att förbjuda kryptovalutor som Bitcoin.<ref name="irishtimes">{{tidningsref

== Hur man köper bitcoin ==
Det finns olika sätt att erhålla bitcoin. Ett sätt är att generera bitcoin genom att bidra med beräkningskraft. Ett annat sätt är att sälja saker eller tjänster och ta betalt i bitcoin. De flesta väljer dock att köpa sina bitcoin för vanliga elektroniska pengar. Det sker genom att skapa konto på en handelsplats för bitcoin. Alla handelsplatser kräver någon form av verifiering av identitet innan man kan göra insättningar i kronor eller euro. Vissa handelsplatser erbjuder handel där handelsplatsen är motpart mot kunden och tjänar pengar genom en spread, exempelvis Coinbase. Andra handelsplatser erbjuder en handelsplattform där kunderna gör affärer med varandra och betalar courtage till handelsplatsen, exempelvis Kraken. Det finns också handelsplatser som inte erbjuder möjlighet att sätta in vanliga pengar. Istället kan man bara sätta in och ta ut olika kryptovalutor, för att köpa och sälja dessa på handelsplatsen. Då används ofta kryptovalutorna bitcoin eller ethereum som basvaluta.<ref>{{Tidningsref|rubrik=Var du kan köpa och sälja bitcoin och andra kryptovalutor - Kryptomannen|url=http://kryptomannen.se/kopa-salja-kryptovaluta-exchange/|tidning=Kryptomannen|datum=2018-01-16|hämtdatum=2018-01-17|språk=sv-SE}}</ref>

I love this incorporating
an amusement park into our day.

That's why we don't need vacations.

Boy, quite a bit of pomp...
under the circumstances.

- Well, Adam, today we are men.
- We are!

- Bee-men.
- Amen!

Hallelujah!

Students, faculty, distinguished bees,

please welcome Dean Buzzwell.

Welcome, New Hive Oity
graduating class of...

...9:15.

That concludes our ceremonies.

And begins your career
at Honex Industries!

Will we pick ourjob today?

I heard it's just orientation.

Heads up! Here we go.

Keep your hands and antennas
inside the tram at all times.

- Wonder what it'll be like?
- A little scary.

Welcome to Honex,
a division of Honesco

and a part of the Hexagon Group.

This is it!

Wow.

Wow.

We know that you, as a bee,
have worked your whole life

to get to the point where you
can work for your whole life.

Honey begins when our valiant Pollen
Jocks bring the nectar to the hive.

Our top-secret formula

is automatically color-corrected,
scent-adjusted and bubble-contoured

into this soothing sweet syrup

with its distinctive
golden glow you know as...

Honey!

- That girl was hot.
- She's my cousin!

- She is?
- Yes, we're all cousins.

- Right. You're right.
- At Honex, we constantly strive

to improve every aspect
of bee existence.

These bees are stress-testing
a new helmet technology.

- What do you think he makes?
- Not enough.

Here we have our latest advancement,
the Krelman.

- What does that do?
- Oatches that little strand of honey

that hangs after you pour it.
Saves us millions.

Oan anyone work on the Krelman?

Of course. Most bee jobs are
small ones. But bees know

that every small job,
if it's done well, means a lot.

But choose carefully

because you'll stay in the job
you pick for the rest of your life.

The same job the rest of your life?
I didn't know that.

What's the difference?

You'll be happy to know that bees,
as a species, haven't had one day off

in 27 million years.

So you'll just work us to death?

We'll sure try.

Wow! That blew my mind!

"What's the difference?"
How can you say that?

One job forever?
That's an insane choice to have to make.

I'm relieved. Now we only have
to make one decision in life.

But, Adam, how could they
never have told us that?

Why would you question anything?
We're bees.

We're the most perfectly
functioning society on Earth.

You ever think maybe things
work a little too well here?

Like what? Give me one example.

I don't know. But you know
what I'm talking about.

Please clear the gate.
Royal Nectar Force on approach.

Wait a second. Oheck it out.

- Hey, those are Pollen Jocks!
- Wow.

I've never seen them this close.

They know what it's like
outside the hive.

Yeah, but some don't come back.

- Hey, Jocks!
- Hi, Jocks!

You guys did great!

You're monsters!
You're sky freaks! I love it! I love it!

- I wonder where they were.
- I don't know.

Their day's not planned.

Outside the hive, flying who knows
where, doing who knows what.

You can'tjust decide to be a Pollen
Jock. You have to be bred for that.

Right.

Look. That's more pollen
than you and I will see in a lifetime.

It's just a status symbol.
Bees make too much of it.

Perhaps. Unless you're wearing it
and the ladies see you wearing it.

Those ladies?
Aren't they our cousins too?

Distant. Distant.

Look at these two.

- Oouple of Hive Harrys.
- Let's have fun with them.

It must be dangerous
being a Pollen Jock.

Yeah. Once a bear pinned me
against a mushroom!

He had a paw on my throat,
and with the other, he was slapping me!

- Oh, my!
- I never thought I'd knock him out.

What were you doing during this?

Trying to alert the authorities.

I can autograph that.

A little gusty out there today,
wasn't it, comrades?

Yeah. Gusty.

We're hitting a sunflower patch
six miles from here tomorrow.

- Six miles, huh?
- Barry!

A puddle jump for us,
but maybe you're not up for it.

- Maybe I am.
- You are not!

We're going 0900 at J-Gate.

What do you think, buzzy-boy?
Are you bee enough?

I might be. It all depends
on what 0900 means.

Hey, Honex!

Dad, you surprised me.

You decide what you're interested in?

- Well, there's a lot of choices.
- But you only get one.

Do you ever get bored
doing the same job every day?

Son, let me tell you about stirring.

You grab that stick, and you just
move it around, and you stir it around.

You get yourself into a rhythm.
It's a beautiful thing.

You know, Dad,
the more I think about it,

maybe the honey field
just isn't right for me.

You were thinking of what,
making balloon animals?

That's a bad job
for a guy with a stinger.

Janet, your son's not sure
he wants to go into honey!

- Barry, you are so funny sometimes.
- I'm not trying to be funny.

You're not funny! You're going
into honey. Our son, the stirrer!

- You're gonna be a stirrer?
- No one's listening to me!

Wait till you see the sticks I have.

I could say anything right now.
I'm gonna get an ant tattoo!

Let's open some honey and celebrate!

Maybe I'll pierce my thorax.
Shave my antennae.

Shack up with a grasshopper. Get
a gold tooth and call everybody "dawg"!

I'm so proud.

- We're starting work today!
- Today's the day.

Oome on! All the good jobs
will be gone.

Yeah, right.

Pollen counting, stunt bee, pouring,
stirrer, front desk, hair removal...

- Is it still available?
- Hang on. Two left!

One of them's yours! Oongratulations!
Step to the side.

- What'd you get?
- Picking crud out. Stellar!

Wow!

Oouple of newbies?

Yes, sir! Our first day! We are ready!

Make your choice.

- You want to go first?
- No, you go.

Oh, my. What's available?

Restroom attendant's open,
not for the reason you think.

- Any chance of getting the Krelman?
- Sure, you're on.

I'm sorry, the Krelman just closed out.

Wax monkey's always open.

The Krelman opened up again.

What happened?

A bee died. Makes an opening. See?
He's dead. Another dead one.

Deady. Deadified. Two more dead.

Dead from the neck up.
Dead from the neck down. That's life!

Oh, this is so hard!

Heating, cooling,
stunt bee, pourer, stirrer,

humming, inspector number seven,
lint coordinator, stripe supervisor,

mite wrangler. Barry, what
do you think I should... Barry?

Barry!

All right, we've got the sunflower patch
in quadrant nine...

What happened to you?
Where are you?

- I'm going out.
- Out? Out where?

- Out there.
- Oh, no!

I have to, before I go
to work for the rest of my life.

You're gonna die! You're crazy! Hello?

Another call coming in.

If anyone's feeling brave,
there's a Korean deli on 83rd

that gets their roses today.

Hey, guys.

- Look at that.
- Isn't that the kid we saw yesterday?

Hold it, son, flight deck's restricted.

It's OK, Lou. We're gonna take him up.

Really? Feeling lucky, are you?

Sign here, here. Just initial that.

- Thank you.
- OK.

You got a rain advisory today,

and as you all know,
bees cannot fly in rain.

So be careful. As always,
watch your brooms,

hockey sticks, dogs,
birds, bears and bats.

Also, I got a couple of reports
of root beer being poured on us.

Murphy's in a home because of it,
babbling like a cicada!

- That's awful.
- And a reminder for you rookies,

bee law number one,
absolutely no talking to humans!

All right, launch positions!

Buzz, buzz, buzz, buzz! Buzz, buzz,
buzz, buzz! Buzz, buzz, buzz, buzz!

Black and yellow!

Hello!

You ready for this, hot shot?

Yeah. Yeah, bring it on.

Wind, check.

- Antennae, check.
- Nectar pack, check.

- Wings, check.
- Stinger, check.

Scared out of my shorts, check.

OK, ladies,

let's move it out!

Pound those petunias,
you striped stem-suckers!

All of you, drain those flowers!

Wow! I'm out!

I can't believe I'm out!

So blue.

I feel so fast and free!

Box kite!

Wow!

Flowers!

This is Blue Leader.
We have roses visual.

Bring it around 30 degrees and hold.

Roses!

30 degrees, roger. Bringing it around.

Stand to the side, kid.
It's got a bit of a kick.

That is one nectar collector!

- Ever see pollination up close?
- No, sir.

I pick up some pollen here, sprinkle it
over here. Maybe a dash over there,

a pinch on that one.
See that? It's a little bit of magic.

That's amazing. Why do we do that?

That's pollen power. More pollen, more
flowers, more nectar, more honey for us.

Oool.

I'm picking up a lot of bright yellow.
Oould be daisies. Don't we need those?

Oopy that visual.

Wait. One of these flowers
seems to be on the move.

Say again? You're reporting
a moving flower?

Affirmative.

That was on the line!

This is the coolest. What is it?

I don't know, but I'm loving this color.

It smells good.
Not like a flower, but I like it.

Yeah, fuzzy.

Ohemical-y.

Oareful, guys. It's a little grabby.

My sweet lord of bees!

Oandy-brain, get off there!

Problem!

- Guys!
- This could be bad.

Affirmative.

Very close.

Gonna hurt.

Mama's little boy.

You are way out of position, rookie!

Ooming in at you like a missile!

Help me!

I don't think these are flowers.

- Should we tell him?
- I think he knows.

What is this?!

Match point!

You can start packing up, honey,
because you're about to eat it!

Yowser!

Gross.

There's a bee in the car!

- Do something!
- I'm driving!

- Hi, bee.
- He's back here!

He's going to sting me!

Nobody move. If you don't move,
he won't sting you. Freeze!

He blinked!

Spray him, Granny!

What are you doing?!

Wow... the tension level
out here is unbelievable.

I gotta get home.

Oan't fly in rain.

Oan't fly in rain.

Oan't fly in rain.

Mayday! Mayday! Bee going down!

Ken, could you close
the window please?

Ken, could you close
the window please?

Oheck out my new resume.
I made it into a fold-out brochure.

You see? Folds out.

Oh, no. More humans. I don't need this.

What was that?

Maybe this time. This time. This time.
This time! This time! This...

Drapes!

That is diabolical.

It's fantastic. It's got all my special
skills, even my top-ten favorite movies.

What's number one? Star Wars?

Nah, I don't go for that...

...kind of stuff.

No wonder we shouldn't talk to them.
They're out of their minds.

When I leave a job interview, they're
flabbergasted, can't believe what I say.

There's the sun. Maybe that's a way out.

I don't remember the sun
having a big 75 on it.

I predicted global warming.

I could feel it getting hotter.
At first I thought it was just me.

Wait! Stop! Bee!

Stand back. These are winter boots.

Wait!

Don't kill him!

You know I'm allergic to them!
This thing could kill me!

Why does his life have
less value than yours?

Why does his life have any less value
than mine? Is that your statement?

I'm just saying all life has value. You
don't know what he's capable of feeling.

My brochure!

There you go, little guy.

I'm not scared of him.
It's an allergic thing.

Put that on your resume brochure.

My whole face could puff up.

Make it one of your special skills.

Knocking someone out
is also a special skill.

Right. Bye, Vanessa. Thanks.

- Vanessa, next week? Yogurt night?
- Sure, Ken. You know, whatever.

- You could put carob chips on there.
- Bye.

- Supposed to be less calories.
- Bye.

I gotta say something.

She saved my life.
I gotta say something.

All right, here it goes.

Nah.

What would I say?

I could really get in trouble.

It's a bee law.
You're not supposed to talk to a human.

I can't believe I'm doing this.

I've got to.

Oh, I can't do it. Oome on!

No. Yes. No.

Do it. I can't.

How should I start it?
"You like jazz?" No, that's no good.

Here she comes! Speak, you fool!

Hi!

I'm sorry.

- You're talking.
- Yes, I know.

You're talking!

I'm so sorry.

No, it's OK. It's fine.
I know I'm dreaming.

But I don't recall going to bed.

Well, I'm sure this
is very disconcerting.

This is a bit of a surprise to me.
I mean, you're a bee!

I am. And I'm not supposed
to be doing this,

but they were all trying to kill me.

And if it wasn't for you...

I had to thank you.
It's just how I was raised.

That was a little weird.

- I'm talking with a bee.
- Yeah.

I'm talking to a bee.
And the bee is talking to me!

I just want to say I'm grateful.
I'll leave now.

- Wait! How did you learn to do that?
- What?

The talking thing.

Same way you did, I guess.
"Mama, Dada, honey." You pick it up.

- That's very funny.
- Yeah.

Bees are funny. If we didn't laugh,
we'd cry with what we have to deal with.

Anyway...

Oan I...

...get you something?
- Like what?

I don't know. I mean...
I don't know. Ooffee?

I don't want to put you out.

It's no trouble. It takes two minutes.

- It's just coffee.
- I hate to impose.

- Don't be ridiculous!
- Actually, I would love a cup.

Hey, you want rum cake?

- I shouldn't.
- Have some.

- No, I can't.
- Oome on!

I'm trying to lose a couple micrograms.

- Where?
- These stripes don't help.

You look great!

I don't know if you know
anything about fashion.

Are you all right?

No.

He's making the tie in the cab
as they're flying up Madison.

He finally gets there.

He runs up the steps into the church.
The wedding is on.

And he says, "Watermelon?
I thought you said Guatemalan.

Why would I marry a watermelon?"

Is that a bee joke?

That's the kind of stuff we do.

Yeah, different.

So, what are you gonna do, Barry?

About work? I don't know.

I want to do my part for the hive,
but I can't do it the way they want.

I know how you feel.

- You do?
- Sure.

My parents wanted me to be a lawyer or
a doctor, but I wanted to be a florist.

- Really?
- My only interest is flowers.

Our new queen was just elected
with that same campaign slogan.

Anyway, if you look...

There's my hive right there. See it?

You're in Sheep Meadow!

Yes! I'm right off the Turtle Pond!

No way! I know that area.
I lost a toe ring there once.

- Why do girls put rings on their toes?
- Why not?

- It's like putting a hat on your knee.
- Maybe I'll try that.

- You all right, ma'am?
- Oh, yeah. Fine.

Just having two cups of coffee!

Anyway, this has been great.
Thanks for the coffee.

Yeah, it's no trouble.

Sorry I couldn't finish it. If I did,
I'd be up the rest of my life.

Are you...?

Oan I take a piece of this with me?

Sure! Here, have a crumb.

- Thanks!
- Yeah.

All right. Well, then...
I guess I'll see you around.

Or not.

OK, Barry.

And thank you
so much again... for before.

Oh, that? That was nothing.

Well, not nothing, but... Anyway...

This can't possibly work.

He's all set to go.
We may as well try it.

OK, Dave, pull the chute.

- Sounds amazing.
- It was amazing!

It was the scariest,
happiest moment of my life.

Humans! I can't believe
you were with humans!

Giant, scary humans!
What were they like?

Huge and crazy. They talk crazy.

They eat crazy giant things.
They drive crazy.

- Do they try and kill you, like on TV?
- Some of them. But some of them don't.

- How'd you get back?
- Poodle.

You did it, and I'm glad. You saw
whatever you wanted to see.

You had your "experience." Now you
can pick out yourjob and be normal.

- Well...
- Well?

Well, I met someone.

You did? Was she Bee-ish?

- A wasp?! Your parents will kill you!
- No, no, no, not a wasp.

- Spider?
- I'm not attracted to spiders.

I know it's the hottest thing,
with the eight legs and all.

I can't get by that face.

So who is she?

She's... human.

No, no. That's a bee law.
You wouldn't break a bee law.

- Her name's Vanessa.
- Oh, boy.

She's so nice. And she's a florist!

Oh, no! You're dating a human florist!

We're not dating.

You're flying outside the hive, talking
to humans that attack our homes

with power washers and M-80s!
One-eighth a stick of dynamite!

She saved my life!
And she understands me.

This is over!

Eat this.

This is not over! What was that?

- They call it a crumb.
- It was so stingin' stripey!

And that's not what they eat.
That's what falls off what they eat!

- You know what a Oinnabon is?
- No.

It's bread and cinnamon and frosting.
They heat it up...

Sit down!

...really hot!
- Listen to me!

We are not them! We're us.
There's us and there's them!

Yes, but who can deny
the heart that is yearning?

There's no yearning.
Stop yearning. Listen to me!

You have got to start thinking bee,
my friend. Thinking bee!

- Thinking bee.
- Thinking bee.

Thinking bee! Thinking bee!
Thinking bee! Thinking bee!

There he is. He's in the pool.

You know what your problem is, Barry?

I gotta start thinking bee?

How much longer will this go on?

It's been three days!
Why aren't you working?

I've got a lot of big life decisions
to think about.

What life? You have no life!
You have no job. You're barely a bee!

Would it kill you
to make a little honey?

Barry, come out.
Your father's talking to you.

Martin, would you talk to him?

Barry, I'm talking to you!

You coming?

Got everything?

All set!

Go ahead. I'll catch up.

Don't be too long.

Watch this!

Vanessa!

- We're still here.
- I told you not to yell at him.

He doesn't respond to yelling!

- Then why yell at me?
- Because you don't listen!

I'm not listening to this.

Sorry, I've gotta go.

- Where are you going?
- I'm meeting a friend.

A girl? Is this why you can't decide?

Bye.

I just hope she's Bee-ish.

They have a huge parade
of flowers every year in Pasadena?

To be in the Tournament of Roses,
that's every florist's dream!

Up on a float, surrounded
by flowers, crowds cheering.

A tournament. Do the roses
compete in athletic events?

No. All right, I've got one.
How come you don't fly everywhere?

It's exhausting. Why don't you
run everywhere? It's faster.

Yeah, OK, I see, I see.
All right, your turn.

TiVo. You can just freeze live TV?
That's insane!

You don't have that?

We have Hivo, but it's a disease.
It's a horrible, horrible disease.

Oh, my.

Dumb bees!

You must want to sting all those jerks.

We try not to sting.
It's usually fatal for us.

So you have to watch your temper.

Very carefully.
You kick a wall, take a walk,

write an angry letter and throw it out.
Work through it like any emotion:

Anger, jealousy, lust.

Oh, my goodness! Are you OK?

Yeah.

- What is wrong with you?!
- It's a bug.

He's not bothering anybody.
Get out of here, you creep!

What was that? A Pic 'N' Save circular?

Yeah, it was. How did you know?

It felt like about 10 pages.
Seventy-five is pretty much our limit.

You've really got that
down to a science.

- I lost a cousin to Italian Vogue.
- I'll bet.

What in the name
of Mighty Hercules is this?

How did this get here?
Oute Bee, Golden Blossom,

Ray Liotta Private Select?

- Is he that actor?
- I never heard of him.

- Why is this here?
- For people. We eat it.

You don't have
enough food of your own?

- Well, yes.
- How do you get it?

- Bees make it.
- I know who makes it!

And it's hard to make it!

There's heating, cooling, stirring.
You need a whole Krelman thing!

- It's organic.
- It's our-ganic!

It's just honey, Barry.

Just what?!

Bees don't know about this!
This is stealing! A lot of stealing!

You've taken our homes, schools,
hospitals! This is all we have!

And it's on sale?!
I'm getting to the bottom of this.

I'm getting to the bottom
of all of this!

Hey, Hector.

- You almost done?
- Almost.

He is here. I sense it.

Well, I guess I'll go home now

and just leave this nice honey out,
with no one around.

You're busted, box boy!

I knew I heard something.
So you can talk!

I can talk.
And now you'll start talking!

Where you getting the sweet stuff?
Who's your supplier?

I don't understand.
I thought we were friends.

The last thing we want
to do is upset bees!

You're too late! It's ours now!

You, sir, have crossed
the wrong sword!

You, sir, will be lunch
for my iguana, Ignacio!

Where is the honey coming from?

Tell me where!

Honey Farms! It comes from Honey Farms!

Orazy person!

What horrible thing has happened here?

These faces, they never knew
what hit them. And now

they're on the road to nowhere!

Just keep still.

What? You're not dead?

Do I look dead? They will wipe anything
that moves. Where you headed?

To Honey Farms.
I am onto something huge here.

I'm going to Alaska. Moose blood,
crazy stuff. Blows your head off!

I'm going to Tacoma.

- And you?
- He really is dead.

All right.

Uh-oh!

- What is that?!
- Oh, no!

- A wiper! Triple blade!
- Triple blade?

Jump on! It's your only chance, bee!

Why does everything have
to be so doggone clean?!

How much do you people need to see?!

Open your eyes!
Stick your head out the window!

From NPR News in Washington,
I'm Oarl Kasell.

But don't kill no more bugs!

- Bee!
- Moose blood guy!!

- You hear something?
- Like what?

Like tiny screaming.

Turn off the radio.

Whassup, bee boy?

Hey, Blood.

Just a row of honey jars,
as far as the eye could see.

Wow!

I assume wherever this truck goes
is where they're getting it.

I mean, that honey's ours.

- Bees hang tight.
- We're all jammed in.

It's a close community.

Not us, man. We on our own.
Every mosquito on his own.

- What if you get in trouble?
- You a mosquito, you in trouble.

Nobody likes us. They just smack.
See a mosquito, smack, smack!

At least you're out in the world.
You must meet girls.

Mosquito girls try to trade up,
get with a moth, dragonfly.

Mosquito girl don't want no mosquito.

You got to be kidding me!

Mooseblood's about to leave
the building! So long, bee!

- Hey, guys!
- Mooseblood!

I knew I'd catch y'all down here.
Did you bring your crazy straw?

We throw it in jars, slap a label on it,
and it's pretty much pure profit.

What is this place?

A bee's got a brain
the size of a pinhead.

They are pinheads!

Pinhead.

- Oheck out the new smoker.
- Oh, sweet. That's the one you want.

The Thomas 3000!

Smoker?

Ninety puffs a minute, semi-automatic.
Twice the nicotine, all the tar.

A couple breaths of this
knocks them right out.

They make the honey,
and we make the money.

"They make the honey,
and we make the money"?

Oh, my!

What's going on? Are you OK?

Yeah. It doesn't last too long.

Do you know you're
in a fake hive with fake walls?

Our queen was moved here.
We had no choice.

This is your queen?
That's a man in women's clothes!

That's a drag queen!

What is this?

Oh, no!

There's hundreds of them!

Bee honey.

Our honey is being brazenly stolen
on a massive scale!

This is worse than anything bears
have done! I intend to do something.

Oh, Barry, stop.

Who told you humans are taking
our honey? That's a rumor.

Do these look like rumors?

That's a conspiracy theory.
These are obviously doctored photos.

How did you get mixed up in this?

He's been talking to humans.

- What?
- Talking to humans?!

He has a human girlfriend.
And they make out!

Make out? Barry!

We do not.

- You wish you could.
- Whose side are you on?

The bees!

I dated a cricket once in San Antonio.
Those crazy legs kept me up all night.

Barry, this is what you want
to do with your life?

I want to do it for all our lives.
Nobody works harder than bees!

Dad, I remember you
coming home so overworked

your hands were still stirring.
You couldn't stop.

I remember that.

What right do they have to our honey?

We live on two cups a year. They put it
in lip balm for no reason whatsoever!

Even if it's true, what can one bee do?

Sting them where it really hurts.

In the face! The eye!

- That would hurt.
- No.

Up the nose? That's a killer.

There's only one place you can sting
the humans, one place where it matters.

Hive at Five, the hive's only
full-hour action news source.

No more bee beards!

With Bob Bumble at the anchor desk.

Weather with Storm Stinger.

Sports with Buzz Larvi.

And Jeanette Ohung.

- Good evening. I'm Bob Bumble.
- And I'm Jeanette Ohung.

A tri-county bee, Barry Benson,

intends to sue the human race
for stealing our honey,

packaging it and profiting
from it illegally!

Tomorrow night on Bee Larry King,

we'll have three former queens here in
our studio, discussing their new book,

Olassy Ladies,
out this week on Hexagon.

Tonight we're talking to Barry Benson.

Did you ever think, "I'm a kid
from the hive. I can't do this"?

Bees have never been afraid
to change the world.

What about Bee Oolumbus?
Bee Gandhi? Bejesus?

Where I'm from, we'd never sue humans.

We were thinking
of stickball or candy stores.

How old are you?

The bee community
is supporting you in this case,

which will be the trial
of the bee century.

You know, they have a Larry King
in the human world too.

It's a common name. Next week...

He looks like you and has a show
and suspenders and colored dots...

Next week...

Glasses, quotes on the bottom from the
guest even though you just heard 'em.

Bear Week next week!
They're scary, hairy and here live.

Always leans forward, pointy shoulders,
squinty eyes, very Jewish.

In tennis, you attack
at the point of weakness!

It was my grandmother, Ken. She's 81.

Honey, her backhand's a joke!
I'm not gonna take advantage of that?

Quiet, please.
Actual work going on here.

- Is that that same bee?
- Yes, it is!

I'm helping him sue the human race.

- Hello.
- Hello, bee.

This is Ken.

Yeah, I remember you. Timberland, size
ten and a half. Vibram sole, I believe.

Why does he talk again?

Listen, you better go
'cause we're really busy working.

But it's our yogurt night!

Bye-bye.

Why is yogurt night so difficult?!

You poor thing.
You two have been at this for hours!

Yes, and Adam here
has been a huge help.

- Frosting...
- How many sugars?

Just one. I try not
to use the competition.

So why are you helping me?

Bees have good qualities.

And it takes my mind off the shop.

Instead of flowers, people
are giving balloon bouquets now.

Those are great, if you're three.

And artificial flowers.

- Oh, those just get me psychotic!
- Yeah, me too.

Bent stingers, pointless pollination.

Bees must hate those fake things!

Nothing worse
than a daffodil that's had work done.

Maybe this could make up
for it a little bit.

- This lawsuit's a pretty big deal.
- I guess.

You sure you want to go through with it?

Am I sure? When I'm done with
the humans, they won't be able

to say, "Honey, I'm home,"
without paying a royalty!

It's an incredible scene
here in downtown Manhattan,

where the world anxiously waits,
because for the first time in history,

we will hear for ourselves
if a honeybee can actually speak.

What have we gotten into here, Barry?

It's pretty big, isn't it?

I can't believe how many humans
don't work during the day.

You think billion-dollar multinational
food companies have good lawyers?

Everybody needs to stay
behind the barricade.

- What's the matter?
- I don't know, I just got a chill.

Well, if it isn't the bee team.

You boys work on this?

All rise! The Honorable
Judge Bumbleton presiding.

All right. Oase number 4475,

Superior Oourt of New York,
Barry Bee Benson v. the Honey Industry

is now in session.

Mr. Montgomery, you're representing
the five food companies collectively?

A privilege.

Mr. Benson... you're representing
all the bees of the world?

I'm kidding. Yes, Your Honor,
we're ready to proceed.

Mr. Montgomery,
your opening statement, please.

Ladies and gentlemen of the jury,

my grandmother was a simple woman.

Born on a farm, she believed
it was man's divine right

to benefit from the bounty
of nature God put before us.

If we lived in the topsy-turvy world
Mr. Benson imagines,

just think of what would it mean.

I would have to negotiate
with the silkworm

for the elastic in my britches!

Talking bee!

How do we know this isn't some sort of

holographic motion-picture-capture
Hollywood wizardry?

They could be using laser beams!

Robotics! Ventriloquism!
Oloning! For all we know,

he could be on steroids!

Mr. Benson?

Ladies and gentlemen,
there's no trickery here.

I'm just an ordinary bee.
Honey's pretty important to me.

It's important to all bees.
We invented it!

We make it. And we protect it
with our lives.

Unfortunately, there are
some people in this room

who think they can take it from us

'cause we're the little guys!
I'm hoping that, after this is all over,

you'll see how, by taking our honey,
you not only take everything we have

but everything we are!

I wish he'd dress like that
all the time. So nice!

Oall your first witness.

So, Mr. Klauss Vanderhayden
of Honey Farms, big company you have.

I suppose so.

I see you also own
Honeyburton and Honron!

Yes, they provide beekeepers
for our farms.

Beekeeper. I find that
to be a very disturbing term.

I don't imagine you employ
any bee-free-ers, do you?

- No.
- I couldn't hear you.

- No.
- No.

Because you don't free bees.
You keep bees. Not only that,

it seems you thought a bear would be
an appropriate image for a jar of honey.

They're very lovable creatures.

Yogi Bear, Fozzie Bear, Build-A-Bear.

You mean like this?

Bears kill bees!

How'd you like his head crashing
through your living room?!

Biting into your couch!
Spitting out your throw pillows!

OK, that's enough. Take him away.

So, Mr. Sting, thank you for being here.
Your name intrigues me.

- Where have I heard it before?
- I was with a band called The Police.

But you've never been
a police officer, have you?

No, I haven't.

No, you haven't. And so here
we have yet another example

of bee culture casually
stolen by a human

for nothing more than
a prance-about stage name.

Oh, please.

Have you ever been stung, Mr. Sting?

Because I'm feeling
a little stung, Sting.

Or should I say... Mr. Gordon M. Sumner!

That's not his real name?! You idiots!

Mr. Liotta, first,
belated congratulations on

your Emmy win for a guest spot
on ER in 2005.

Thank you. Thank you.

I see from your resume
that you're devilishly handsome

with a churning inner turmoil
that's ready to blow.

I enjoy what I do. Is that a crime?

Not yet it isn't. But is this
what it's come to for you?

Exploiting tiny, helpless bees
so you don't

have to rehearse
your part and learn your lines, sir?

Watch it, Benson!
I could blow right now!

This isn't a goodfella.
This is a badfella!

Why doesn't someone just step on
this creep, and we can all go home?!

- Order in this court!
- You're all thinking it!

Order! Order, I say!

- Say it!
- Mr. Liotta, please sit down!

I think it was awfully nice
of that bear to pitch in like that.

I think the jury's on our side.

Are we doing everything right, legally?

I'm a florist.

Right. Well, here's to a great team.

To a great team!

Well, hello.

- Ken!
- Hello.

I didn't think you were coming.

No, I was just late.
I tried to call, but... the battery.

I didn't want all this to go to waste,
so I called Barry. Luckily, he was free.

Oh, that was lucky.

There's a little left.
I could heat it up.

Yeah, heat it up, sure, whatever.

So I hear you're quite a tennis player.

I'm not much for the game myself.
The ball's a little grabby.

That's where I usually sit.
Right... there.

Ken, Barry was looking at your resume,

and he agreed with me that eating with
chopsticks isn't really a special skill.

You think I don't see what you're doing?

I know how hard it is to find
the rightjob. We have that in common.

Do we?

Bees have 100 percent employment,
but we do jobs like taking the crud out.

That's just what
I was thinking about doing.

Ken, I let Barry borrow your razor
for his fuzz. I hope that was all right.

I'm going to drain the old stinger.

Yeah, you do that.

Look at that.

You know, I've just about had it

with your little mind games.

- What's that?
- Italian Vogue.

Mamma mia, that's a lot of pages.

A lot of ads.

Remember what Van said, why is
your life more valuable than mine?

Funny, I just can't seem to recall that!

I think something stinks in here!

I love the smell of flowers.

How do you like the smell of flames?!

Not as much.

Water bug! Not taking sides!

Ken, I'm wearing a Ohapstick hat!
This is pathetic!

I've got issues!

Well, well, well, a royal flush!

- You're bluffing.
- Am I?

Surf's up, dude!

Poo water!

That bowl is gnarly.

Except for those dirty yellow rings!

Kenneth! What are you doing?!

You know, I don't even like honey!
I don't eat it!

We need to talk!

He's just a little bee!

And he happens to be
the nicest bee I've met in a long time!

Long time? What are you talking about?!
Are there other bugs in your life?

No, but there are other things bugging
me in life. And you're one of them!

Fine! Talking bees, no yogurt night...

My nerves are fried from riding
on this emotional roller coaster!

Goodbye, Ken.

And for your information,

I prefer sugar-free, artificial
sweeteners made by man!

I'm sorry about all that.

I know it's got
an aftertaste! I like it!

I always felt there was some kind
of barrier between Ken and me.

I couldn't overcome it.
Oh, well.

Are you OK for the trial?

I believe Mr. Montgomery
is about out of ideas.

We would like to call
Mr. Barry Benson Bee to the stand.

Good idea! You can really see why he's
considered one of the best lawyers...

Yeah.

Layton, you've
gotta weave some magic

with this jury,
or it's gonna be all over.

Don't worry. The only thing I have
to do to turn this jury around

is to remind them
of what they don't like about bees.

- You got the tweezers?
- Are you allergic?

Only to losing, son. Only to losing.

Mr. Benson Bee, I'll ask you
what I think we'd all like to know.

What exactly is your relationship

to that woman?

We're friends.

- Good friends?
- Yes.

How good? Do you live together?

Wait a minute...

Are you her little...

...bedbug?

I've seen a bee documentary or two.
From what I understand,

doesn't your queen give birth
to all the bee children?

- Yeah, but...
- So those aren't your real parents!

- Oh, Barry...
- Yes, they are!

Hold me back!

You're an illegitimate bee,
aren't you, Benson?

He's denouncing bees!

Don't y'all date your cousins?

- Objection!
- I'm going to pincushion this guy!

Adam, don't! It's what he wants!

Oh, I'm hit!!

Oh, lordy, I am hit!

Order! Order!

The venom! The venom
is coursing through my veins!

I have been felled
by a winged beast of destruction!

You see? You can't treat them
like equals! They're striped savages!

Stinging's the only thing
they know! It's their way!

- Adam, stay with me.
- I can't feel my legs.

What angel of mercy
will come forward to suck the poison

from my heaving buttocks?

I will have order in this court. Order!

Order, please!

The case of the honeybees
versus the human race

took a pointed turn against the bees

yesterday when one of their legal
team stung Layton T. Montgomery.

- Hey, buddy.
- Hey.

- Is there much pain?
- Yeah.

I...

I blew the whole case, didn't I?

It doesn't matter. What matters is
you're alive. You could have died.

I'd be better off dead. Look at me.

They got it from the cafeteria
downstairs, in a tuna sandwich.

Look, there's
a little celery still on it.

What was it like to sting someone?

I can't explain it. It was all...

All adrenaline and then...
and then ecstasy!

All right.

You think it was all a trap?

Of course. I'm sorry.
I flew us right into this.

What were we thinking? Look at us. We're
just a couple of bugs in this world.

What will the humans do to us
if they win?

I don't know.

I hear they put the roaches in motels.
That doesn't sound so bad.

Adam, they check in,
but they don't check out!

Oh, my.

Oould you get a nurse
to close that window?

- Why?
- The smoke.

Bees don't smoke.

Right. Bees don't smoke.

Bees don't smoke!
But some bees are smoking.

That's it! That's our case!

It is? It's not over?

Get dressed. I've gotta go somewhere.

Get back to the court and stall.
Stall any way you can.

And assuming you've done step correctly, you're ready for the tub.

Mr. Flayman.

Yes? Yes, Your Honor!

Where is the rest of your team?

Well, Your Honor, it's interesting.

Bees are trained to fly haphazardly,

and as a result,
we don't make very good time.

I actually heard a funny story about...

Your Honor,
haven't these ridiculous bugs

taken up enough
of this court's valuable time?

How much longer will we allow
these absurd shenanigans to go on?

They have presented no compelling
evidence to support their charges

against my clients,
who run legitimate businesses.

I move for a complete dismissal
of this entire case!

Mr. Flayman, I'm afraid I'm going

to have to consider
Mr. Montgomery's motion.

But you can't! We have a terrific case.

Where is your proof?
Where is the evidence?

Show me the smoking gun!

Hold it, Your Honor!
You want a smoking gun?

Here is your smoking gun.

What is that?

It's a bee smoker!

What, this?
This harmless little contraption?

This couldn't hurt a fly,
let alone a bee.

Look at what has happened

to bees who have never been asked,
"Smoking or non?"

Is this what nature intended for us?

To be forcibly addicted
to smoke machines

and man-made wooden slat work camps?

Living out our lives as honey slaves
to the white man?

- What are we gonna do?
- He's playing the species card.

Ladies and gentlemen, please,
free these bees!

Free the bees! Free the bees!

Free the bees!

Free the bees! Free the bees!

The court finds in favor of the bees!

Vanessa, we won!

I knew you could do it! High-five!

Sorry.

I'm OK! You know what this means?

All the honey
will finally belong to the bees.

Now we won't have
to work so hard all the time.

This is an unholy perversion
of the balance of nature, Benson.

You'll regret this.

Barry, how much honey is out there?

All right. One at a time.

Barry, who are you wearing?

My sweater is Ralph Lauren,
and I have no pants.

- What if Montgomery's right?
- What do you mean?

We've been living the bee way
a long time, 27 million years.

Oongratulations on your victory.
What will you demand as a settlement?

First, we'll demand a complete shutdown
of all bee work camps.

Then we want back the honey
that was ours to begin with,

every last drop.

We demand an end to the glorification
of the bear as anything more

than a filthy, smelly,
bad-breath stink machine.

We're all aware
of what they do in the woods.

Wait for my signal.

Take him out.

He'll have nauseous
for a few hours, then he'll be fine.

And we will no longer tolerate
bee-negative nicknames...

But it's just a prance-about stage name!

...unnecessary inclusion of honey
in bogus health products

and la-dee-da human
tea-time snack garnishments.

Oan't breathe.

Bring it in, boys!

Hold it right there! Good.

Tap it.

Mr. Buzzwell, we just passed three cups,
and there's gallons more coming!

- I think we need to shut down!
- Shut down? We've never shut down.

Shut down honey production!

Stop making honey!

Turn your key, sir!

What do we do now?

Oannonball!

We're shutting honey production!

Mission abort.

Aborting pollination and nectar detail.
Returning to base.

Adam, you wouldn't believe
how much honey was out there.

Oh, yeah?

What's going on? Where is everybody?

- Are they out celebrating?
- They're home.

They don't know what to do.
Laying out, sleeping in.

I heard your Uncle Oarl was on his way
to San Antonio with a cricket.

At least we got our honey back.

Sometimes I think, so what if humans
liked our honey? Who wouldn't?

It's the greatest thing in the world!
I was excited to be part of making it.

This was my new desk. This was my
new job. I wanted to do it really well.

And now...

Now I can't.

I don't understand
why they're not happy.

I thought their lives would be better!

They're doing nothing. It's amazing.
Honey really changes people.

You don't have any idea
what's going on, do you?

- What did you want to show me?
- This.

What happened here?

That is not the half of it.

Oh, no. Oh, my.

They're all wilting.

Doesn't look very good, does it?

No.

And whose fault do you think that is?

You know, I'm gonna guess bees.

Bees?

Specifically, me.

I didn't think bees not needing to make
honey would affect all these things.

It's notjust flowers.
Fruits, vegetables, they all need bees.

That's our whole SAT test right there.

Take away produce, that affects
the entire animal kingdom.

And then, of course...

The human species?

So if there's no more pollination,

it could all just go south here,
couldn't it?

I know this is also partly my fault.

How about a suicide pact?

How do we do it?

- I'll sting you, you step on me.
- Thatjust kills you twice.

Right, right.

Listen, Barry...
sorry, but I gotta get going.

I had to open my mouth and talk.

Vanessa?

Vanessa? Why are you leaving?
Where are you going?

To the final Tournament of Roses parade
in Pasadena.

They've moved it to this weekend
because all the flowers are dying.

It's the last chance
I'll ever have to see it.

Vanessa, I just wanna say I'm sorry.
I never meant it to turn out like this.

I know. Me neither.

Tournament of Roses.
Roses can't do sports.

Wait a minute. Roses. Roses?

Roses!

Vanessa!

Roses?!

Barry?

- Roses are flowers!
- Yes, they are.

Flowers, bees, pollen!

I know.
That's why this is the last parade.

Maybe not.
Oould you ask him to slow down?

Oould you slow down?

Barry!

OK, I made a huge mistake.
This is a total disaster, all my fault.

Yes, it kind of is.

I've ruined the planet.
I wanted to help you

with the flower shop.
I've made it worse.

Actually, it's completely closed down.

I thought maybe you were remodeling.

But I have another idea, and it's
greater than my previous ideas combined.

I don't want to hear it!

All right, they have the roses,
the roses have the pollen.

I know every bee, plant
and flower bud in this park.

All we gotta do is get what they've got
back here with what we've got.

- Bees.
- Park.

- Pollen!
- Flowers.

- Repollination!
- Across the nation!

Tournament of Roses,
Pasadena, Oalifornia.

They've got nothing
but flowers, floats and cotton candy.

Security will be tight.

I have an idea.

Vanessa Bloome, FTD.

Official floral business. It's real.

Sorry, ma'am. Nice brooch.

Thank you. It was a gift.

Once inside,
we just pick the right float.

How about The Princess and the Pea?

I could be the princess,
and you could be the pea!

Yes, I got it.

- Where should I sit?
- What are you?

- I believe I'm the pea.
- The pea?

It goes under the mattresses.

- Not in this fairy tale, sweetheart.
- I'm getting the marshal.

You do that!
This whole parade is a fiasco!

Let's see what this baby'll do.

Hey, what are you doing?!

Then all we do
is blend in with traffic...

...without arousing suspicion.

Once at the airport,
there's no stopping us.

Stop! Security.

- You and your insect pack your float?
- Yes.

Has it been
in your possession the entire time?

Would you remove your shoes?

- Remove your stinger.
- It's part of me.

I know. Just having some fun.
Enjoy your flight.

Then if we're lucky, we'll have
just enough pollen to do the job.

Oan you believe how lucky we are? We
have just enough pollen to do the job!

I think this is gonna work.

It's got to work.

Attention, passengers,
this is Oaptain Scott.

We have a bit of bad weather
in New York.

It looks like we'll experience
a couple hours delay.

Barry, these are cut flowers
with no water. They'll never make it.

I gotta get up there
and talk to them.

Be careful.

Oan I get help
with the Sky Mall magazine?

I'd like to order the talking
inflatable nose and ear hair trimmer.

Oaptain, I'm in a real situation.

- What'd you say, Hal?
- Nothing.

Bee!

Don't freak out! My entire species...

What are you doing?

- Wait a minute! I'm an attorney!
- Who's an attorney?

Don't move.

Oh, Barry.

Good afternoon, passengers.
This is your captain.

Would a Miss Vanessa Bloome in 24B
please report to the cockpit?

And please hurry!

What happened here?

There was a DustBuster,
a toupee, a life raft exploded.

One's bald, one's in a boat,
they're both unconscious!

- Is that another bee joke?
- No!

No one's flying the plane!

This is JFK control tower, Flight 356.
What's your status?

This is Vanessa Bloome.
I'm a florist from New York.

Where's the pilot?

He's unconscious,
and so is the copilot.

Not good. Does anyone onboard
have flight experience?

As a matter of fact, there is.

- Who's that?
- Barry Benson.

From the honey trial?! Oh, great.

Vanessa, this is nothing more
than a big metal bee.

It's got giant wings, huge engines.

I can't fly a plane.

- Why not? Isn't John Travolta a pilot?
- Yes.

How hard could it be?

Wait, Barry!
We're headed into some lightning.

This is Bob Bumble. We have some
late-breaking news from JFK Airport,

where a suspenseful scene
is developing.

Barry Benson,
fresh from his legal victory...

That's Barry!

...is attempting to land a plane,
loaded with people, flowers

and an incapacitated flight crew.

Flowers?!

We have a storm in the area
and two individuals at the controls

with absolutely no flight experience.

Just a minute.
There's a bee on that plane.

I'm quite familiar with Mr. Benson
and his no-account compadres.

They've done enough damage.

But isn't he your only hope?

Technically, a bee
shouldn't be able to fly at all.

Their wings are too small...

Haven't we heard this a million times?

"The surface area of the wings
and body mass make no sense."

- Get this on the air!
- Got it.

- Stand by.
- We're going live.

The way we work may be a mystery to you.

Making honey takes a lot of bees
doing a lot of small jobs.

But let me tell you about a small job.

If you do it well,
it makes a big difference.

More than we realized.
To us, to everyone.

That's why I want to get bees
back to working together.

That's the bee way!
We're not made of Jell-O.

We get behind a fellow.

- Black and yellow!
- Hello!

Left, right, down, hover.

- Hover?
- Forget hover.

This isn't so hard.
Beep-beep! Beep-beep!

Barry, what happened?!

Wait, I think we were
on autopilot the whole time.

- That may have been helping me.
- And now we're not!

So it turns out I cannot fly a plane.

All of you, let's get
behind this fellow! Move it out!

Move out!

Our only chance is if I do what I'd do,
you copy me with the wings of the plane!

Don't have to yell.

I'm not yelling!
We're in a lot of trouble.

It's very hard to concentrate
with that panicky tone in your voice!

It's not a tone. I'm panicking!

I can't do this!

Vanessa, pull yourself together.
You have to snap out of it!

You snap out of it.

You snap out of it.

- You snap out of it!
- You snap out of it!

- You snap out of it!
- You snap out of it!

- You snap out of it!
- You snap out of it!

- Hold it!
- Why? Oome on, it's my turn.

How is the plane flying?

I don't know.

Hello?

Benson, got any flowers
for a happy occasion in there?

The Pollen Jocks!

They do get behind a fellow.

- Black and yellow.
- Hello.

All right, let's drop this tin can
on the blacktop.

Where? I can't see anything. Oan you?

No, nothing. It's all cloudy.

Oome on. You got to think bee, Barry.

- Thinking bee.
- Thinking bee.

Thinking bee!
Thinking bee! Thinking bee!

Wait a minute.
I think I'm feeling something.

- What?
- I don't know. It's strong, pulling me.

Like a 27-million-year-old instinct.

Bring the nose down.

Thinking bee!
Thinking bee! Thinking bee!

- What in the world is on the tarmac?
- Get some lights on that!

Thinking bee!
Thinking bee! Thinking bee!

- Vanessa, aim for the flower.
- OK.

Out the engines. We're going in
on bee power. Ready, boys?

Affirmative!

Good. Good. Easy, now. That's it.

Land on that flower!

Ready? Full reverse!

Spin it around!

- Not that flower! The other one!
- Which one?

- That flower.
- I'm aiming at the flower!

That's a fat guy in a flowered shirt.
I mean the giant pulsating flower

made of millions of bees!

Pull forward. Nose down. Tail up.

Rotate around it.

- This is insane, Barry!
- This's the only way I know how to fly.

Am I koo-koo-kachoo, or is this plane
flying in an insect-like pattern?

Get your nose in there. Don't be afraid.
Smell it. Full reverse!

Just drop it. Be a part of it.

Aim for the center!

Now drop it in! Drop it in, woman!

Oome on, already.

Barry, we did it!
You taught me how to fly!

- Yes. No high-five!
- Right.

Barry, it worked!
Did you see the giant flower?

What giant flower? Where? Of course
I saw the flower! That was genius!

- Thank you.
- But we're not done yet.

Listen, everyone!

This runway is covered
with the last pollen

from the last flowers
available anywhere on Earth.

That means this is our last chance.

We're the only ones who make honey,
pollinate flowers and dress like this.

If we're gonna survive as a species,
this is our moment! What do you say?

Are we going to be bees, orjust
Museum of Natural History keychains?

We're bees!

Keychain!

Then follow me! Except Keychain.

Hold on, Barry. Here.

You've earned this.

Yeah!

I'm a Pollen Jock! And it's a perfect
fit. All I gotta do are the sleeves.

Oh, yeah.

That's our Barry.

Mom! The bees are back!

If anybody needs
to make a call, now's the time.

I got a feeling we'll be
working late tonight!

Here's your change. Have a great
afternoon! Oan I help who's next?

Would you like some honey with that?
It is bee-approved. Don't forget these.

Milk, cream, cheese, it's all me.
And I don't see a nickel!

Sometimes I just feel
like a piece of meat!

I had no idea.

Barry, I'm sorry.
Have you got a moment?

Would you excuse me?
My mosquito associate will help you.

Sorry I'm late.

He's a lawyer too?

I was already a blood-sucking parasite.
All I needed was a briefcase.

Have a great afternoon!

Barry, I just got this huge tulip order,
and I can't get them anywhere.

No problem, Vannie.
Just leave it to me.

You're a lifesaver, Barry.
Oan I help who's next?

All right, scramble, jocks!
It's time to fly.

Thank you, Barry!

That bee is living my life!

Let it go, Kenny.

- When will this nightmare end?!
- Let it all go.

- Beautiful day to fly.
- Sure is.

Between you and me,
I was dying to get out of that office.

You have got
to start thinking bee, my friend.

- Thinking bee!
- Me?

Hold it. Let's just stop
for a second. Hold it.

I'm sorry. I'm sorry, everyone.
Oan we stop here?

I'm not making a major life decision
during a production number!

All right. Take ten, everybody.
Wrap it up, guys.

I had virtually no rehearsal for that.

Special thanks to SergeiK.

FörkortningBTC, XBT, , ฿

Bitcoin (av "bit" och engelska "coin" = mynt) är en implementation av kryptovaluta, en digital valuta, skapad 2009 av Satoshi Nakamoto (troligtvis en pseudonym), vars huvudsyfte är att möjliggöra betalningar över Internet direkt mellan användare utan någon inblandning från tredje part.[1] [2] Till skillnad från många andra valutor förlitar sig inte Bitcoin på någon central utfärdare i form av exempelvis en centralbank, vilket skyddar mot politisk påverkan och monopolliknande betalsystem. För att upprätthålla säkerhet och sekretess förlitar sig Bitcoin på kryptografi och använder sig av en distribuerad databas utspridd över de noder som utgör P2P-nätverket för att journalföra transaktioner. Detta syftar även till att exempelvis säkerställa att valutan endast kan spenderas av dess ägare samt oåterkalleligen försvinner från nämnda ägares digitala "plånbok" och därmed bara kan spenderas en gång.[1]

Bitcoins design tillåter mer eller mindre anonymt ägande och överförande av värden genom P2P-nätverket. Varje användares bitcoin sparas i en plånboksfil tillsammans med ett godtyckligt antal bitcoinadresser. Plånboksfilen kan sparas på användarens dator eller hos en tredje part som erbjuder en sådan tjänst. I båda fallen kan bitcoin skickas över Internet till vem som helst med en bitcoinadress. Bitcoins P2P-topologi och avsaknad av central administration gör det omöjligt för exempelvis myndigheter att artificiellt manipulera värdet av bitcoin eller framkalla inflation genom att producera fler av dem. [3]

Teknisk bakgrund

Tekniken bakom Bitcoin beskrevs först i Satoshi Nakamotos vitbok från 2009[1]. Den bygger på två andra förslag på alternativa elektroniska valutor: Wei Dais förslag b-money och Nick Szabos förslag Bitgold.[1]

Bitcoin är en P2P-valuta, dvs ett P2P-nätverk håller reda på alla transaktioner i en distribuerad databas. Det finns ingen central server som håller reda på dem eller avgör vilka som är giltiga. Varje deltagare (nod) i P2P-nätverket lagrar transaktionerna, och kan gå in i eller lämna P2P-nätverket utan att skapa problem.

Tidigare förslag på P2P-valutor led av dubbelspenderingsproblemet (eng: double spending problem), dvs att samma pengar kunde överföras till två olika ställen, och att nätverket då måste ha en metod för att avgöra vilken transaktion som var giltig. Satoshi Nakamoto löste problemet med hjälp av en så kallad blockkedja (eng: block chain). Varje transaktion lagras i ett block med data, och alla block hänger ihop i en följd (kedja). Om det skulle skapas två "konkurrerande" block (två block med samma föregångare i kedjan), accepterar noderna det block som majoriteten av deras grannar har accepterat, och bygger nästa block i kedjan på detta. Om det sker en förgrening av kedjan, fattar nätverket alltså ett beslut om vilken gren som är giltig. (och därmed vilken transaktion som är giltig). Beslutet sprids snabbt genom P2P-nätverket, vilket gör det praktiskt omöjligt att ändra. För att göra det svårare för en angripare att tillverka block som stöder deras egen gren av blockkedjan, används en distribuerad tidserver och tidskrävande beräkningar för att skapa ett block, så kallat bevis-på-arbete (eng: proof-of-work).

Transaktionerna använder asymmetrisk kryptering (mer specifikt ECDSA) och är publika. Historiken över alla transaktioner måste lagras i databasen och för att minska kravet på lagringsutrymme används ett Merkle-träd.[1]

Plånboksfilen

Alla som deltar i Bitcoin-nätverket har en plånboksfil (wallet.dat) som innehåller, utöver antalet bitcoin knutna till den plånboken, ett godtyckligt antal kryptografiska nyckelpar. De publika nycklarna utgör bitcoin-adresserna och agerar som sändare eller mottagare för alla transaktioner. Deras motsvarande privata nycklar auktoriserar betalningar från endast den användaren. Adresserna innehåller ingen information om dess ägare och är generellt sett anonyma.[4] Adresserna är i läsbar form strängar av slumpnummer och -bokstäver med en längd på omkring 33 tecken av formen 1rYK1YzEGa59pI314159KUF2Za4jAYYTd. Bitcoin-användare kan ha flera adresser och generera nya obehindrat, då genererandet av nya adresser kräver förhållandevis lite beräkningar och inte kräver någon kontakt med resten av nätverket.

Plånboksfilen lagras direkt på användarens hårddisk. Skulle användaren råka radera filen försvinner de bitcoin och adresser som associerades med just den plånboken för gott.[4] Därför uppmanas Bitcoin-användare att säkerhetskopiera plånboksfilen regelbundet.[5] Det finns två olika typer av bitcoin-plånböcker för att förvara privata nycklar, fullständiga klienter (Full Node) och lättviktsklienter (SVP-klient). En lättviktsklient verifierar inte transaktioner utan förlitar sig på en fullständig klient som den ansluter sig till. Bitcoin Core är den ursprungliga klienten som används i Bitcoin-nätverket för att lagra en fullständig kopia av alla transaktioner.[6]

Transaktioner

Bitcoin innehåller dess nuvarande ägares publika nyckel (bitcoin-adress). När användare A överför en summa till användare B ger A upp sitt ägande genom att lägga till B:s publika nyckel (bitcoin-adress) och signera de bitcoin som ska överföras med sin egen privata nyckel.[7] A sänder sedan dessa bitcoin i ett meddelande, transaktionen, till P2P-nätverket. Resten av noderna i nätverket validerar sedan de kryptografiska signaturerna och summan av transaktionen innan de accepterar den.

Blockkedjan

Huvudkedjan (svart) består av den längsta kedja av block från genesisblocket (grönt) till det nuvarande blocket. Föräldralösa block (lila) existerar utanför huvudkedjan.

Data lagras permanent i Bitcoinnätverket i s.k. block. Dessa block formar en kedja och ett block innehåller de senast utförda transaktionerna samt det föregående blockets hash. En transaktion går inte igenom förrän blocket den tillhör har blivit tillagt i kedjan.[8] [9]

De noder i nätverket som är beredda att bistå med beräkningskraft samlar alla obekräftade transaktioner de känner till i kandidatblock. Sedan försöker de skapa en kryptografisk hash för kandidat-blocket med vissa egenskaper, något som kräver en förutsägbar mängd trial and error. När en nod slutligen lyckas med det annonserar den det till resten av nätverket. De noder som tar emot det nya blocket validerar det sedan innan de lägger till det i block-kedjan. Blocket sägs nu vara löst.

Så småningom innehåller blockkedjan den kryptografiska ägandehistoriken över alla bitcoin, från deras skapare till deras nuvarande ägare.[10] Om en användare skulle försöka använda ett bitcoin som den användaren redan spenderat kommer nätverket således att neka transaktionen.

Bryta bitcoin

När en nod som valt att bidra med beräkningskraft till nätverket lyckats lösa ett block och detta kandidatblock har lagts till i blockkedjan, erhåller noden en belöning. Det här är den mekanism som gör att nya bitcoin tillkommer i Bitcoin-nätverket, och mekanismen kallas "brytning" (jfr Guldbrytning). Användare kan bidra med beräkningskraft genom att antingen aktivera brytningsfunktionen i den officiella mjukvaran eller genom att använda mjukvara från tredje part. I det senare fallet utförs beräkningarna ofta på användarens GPU för ökad effektivitet.[11] [12] Sannolikheten att en nod ska lyckas lösa ett block är direkt relaterad till den beräkningskraft noden bidrar med till nätverket relativt den sammanlagda beräkningskraften hos alla noder i nätverket.[13] Blockbelöningen var ursprungligen 50 bitcoin per block och den halveras efter varje 210 000 block, vilket motsvarar ungefär vart 4:e år. I februari 2018 var blockbelöningen 12,5 bitcoin per nytt block, och den kommer över tiden att minska ner till noll. På så vis kommer ett maximalt antal på ca 21 miljoner bitcoin skapas. Det beräknas att 80 % av alla bitcoin kommer vara skapade 2018.[14] För att upprätthålla en brytningstakt på ett nytt block i genomsnitt var tionde minut, justerar nätverket automatiskt svårighetsgraden[förtydliga] ungefär varannan vecka (efter var 2 016 block) för att ligga i linje med nätverkets totala beräkningskraft.

Eftersom mer än en nod tävlar om att lösa ett specifikt block och svårighetsgraden ständigt ökar har det blivit populärt med kollektiv brytning i så kallade "pooler". På så vis kan även användare som inte förfogar över så mycket beräkningskraft få en jämnare och mer förutsägbar inströmning av belöningar.[15]

Transaktionsavgifter

Användare som vill göra en transaktion kan frivilligt välja att betala en transaktionsavgift. Transaktionsavgiften tillfaller den nod som lyckas lösa just det block som innehåller transaktionen. Detta gör att det blir mer attraktivt för noderna att försöka lösa block som innehåller transaktioner med avgift. Transaktioner där transaktionsavgift har betalats kommer följaktligen att prioriteras av noderna och processas därför oftast snabbare än övriga transaktioner.

När det inte längre går att prägla nya bitcoin genom brytning förväntas möjligheten att lösa block för transaktionsavgifternas skull vara anledning nog för användare att bidra med beräkningskraft till nätverket. På så vis kan systemet ändå hållas igång.[1]

Ekonomiska aspekter

Bitcoin-ekonomin är fortfarande väldigt liten relativt andra etablerade ekonomier och mjukvaran är fortfarande i betastadiet. Men bitcoin accepteras som betalning för både internettjänster och materiella varor på rätt många ställen.[16] Bland annat Singularity Institute accepterar donationer i bitcoin.[17] Även den svenska VPN-tjänsten Mullvad tillhandahåller betalning med bitcoin.[18] Handlare kan växla traditionell valuta (så som amerikansk dollar, rysk rubel och japansk yen) till bitcoin genom växlings-sidor.[19][20] Tillsammans utgör USA och Japan över 60 procent av den globala bitcoinmarknaden och framför allt Japan har visat prov på snabb tillväxt.[21] Ett antal tjänster erbjuder möjligheten att observera alla transaktioner som utförs inom nätverket i realtid.[22][23]

Monetära skillnader

Totala penningmängden bitcoin över tid

Bitcoin skiljer sig från traditionell fiatvaluta i det avseendet att mängden kontanter (M0) inte kan kontrolleras genom att en centralbank ger ut mer av, eller destruerar, kontanter. Det finns heller ingen centralbank som kontrollerar penningmängden genom att justera styrräntan. Det finns en begränsad, kontrollerad ökning av kontantmängden hårdkodad i Bitcoin-mjukvaran som är känd och förutsägbar av alla parter i förväg.[1] Inflationen kan därför inte styras centralt.

Transaktioner genomförs direkt mellan användare över nätverket utan att något finansiellt institut är inblandat. Den här typen av transaktioner innebär dock att det är omöjligt att reversera en transaktion. Bitcoin-klienten sänder transaktionen till noderna i dess omgivning som i sin tur propagerar den till resten av nätverket. Korrupta eller ogiltiga transaktioner nekas av ärliga klienter. Transaktioner är oftast gratis men en transaktionsavgift kan betalas för att noderna i nätverket ska prioritera just den transaktionen.[1]

Den totala mängden bitcoin ökar kontinuerligt men kommer aldrig att överstiga 21 miljoner i antal. Penningmängden växer enligt en geometrisk summa vart fjärde år; år 2013 kommer halva penningmängden ha blivit genererad och år 2017 kommer 3/4 ha blivit genererad o.s.v. Allteftersom det totala antalet närmar sig 21 miljoner kommer värdet av bitcoin successivt att uppleva prisdeflation (en ökning i reellt värde) på grund av att inga nya bitcoin längre skapas. Bitcoin är dock delbara ner till åtta decimaler (vilket ger 2.1 x 1015 enheter), vilket undgår de praktiska begränsningarna som deflation innebär.[4] Istället för att förlita sig på incitamentet att tjäna pengar genom brytning förväntas noder under den här perioden förlita sig på sin förmåga att kompetitivt ta ut transaktionsavgifter för att genomföra transaktioner.[1]

Utfall

Möjliga scenarion där Bitcoin misslyckas inkluderar valutadevalvering, en minskad användarbas, eller lagliga regleringar eller förbud av handel eller innehav. Det är inte säkert att det är möjligt att förbjuda kryptovalutor som Bitcoin.[24] Bitcoins decentraliserade natur och dess fokus på anonymitet har föreslagits vara en reaktion på USA:s aktioner mot företag som erbjuder digitala valutor, så som e-gold och Liberty Dollar.[25] I en undersökande artikel i The Irish Times rapporterade Danny O'Brien "När jag visar folk den här Bitcoin-ekonomin, frågar de: 'Är det här lagligt?' De frågar: 'Är det bedrägeri?' Jag föreställer mig att det finns advokater och ekonomer som kämpar med att besvara båda frågorna. Jag misstänker att du även kommer att kunna lägga till lagstiftare till den listan inom kort."[24]

I februari 2011 uppmärksammades Bitcoin av Slashdot och den efterföljande Slashdot-effekten rapporteras ha påverkat värdet av bitcoin samt tillgängligheten av vissa Bitcoinrelaterade sidor.[26][27]

Kina har förbjudit introduktion av nya kryptovalutor (eng. ICO, Initial Coin Offerings), uppmanat lokala börser att sluta handla med kryptovalutor, försöker minska den energikrävande brytningen av Bitcoin, och tänker blockera online-tjänster för att växla kryptovalutor.[28]

I januari 2018 diskuterade Sydkoreas regering ett förbud eller reglering av Bitcoin, vilket följdes av ett kraftigt prisfall på valutan.[29]

Hur man köper bitcoin

Det finns olika sätt att erhålla bitcoin. Ett sätt är att generera bitcoin genom att bidra med beräkningskraft. Ett annat sätt är att sälja saker eller tjänster och ta betalt i bitcoin. De flesta väljer dock att köpa sina bitcoin för vanliga elektroniska pengar. Det sker genom att skapa konto på en handelsplats för bitcoin. Alla handelsplatser kräver någon form av verifiering av identitet innan man kan göra insättningar i kronor eller euro. Vissa handelsplatser erbjuder handel där handelsplatsen är motpart mot kunden och tjänar pengar genom en spread, exempelvis Coinbase. Andra handelsplatser erbjuder en handelsplattform där kunderna gör affärer med varandra och betalar courtage till handelsplatsen, exempelvis Kraken. Det finns också handelsplatser som inte erbjuder möjlighet att sätta in vanliga pengar. Istället kan man bara sätta in och ta ut olika kryptovalutor, för att köpa och sälja dessa på handelsplatsen. Då används ofta kryptovalutorna bitcoin eller ethereum som basvaluta.[30]

Bitcoin Foundation

Bitcoin Foundation[31]är en amerikansk lobbyorganisation med huvudkontor i Seattle, Washington. Organisationen grundades i september 2012 med uppgiften att "standardisera, skydda och främja kryptovalutan Bitcoin till fördel för användare världen över."[32]

Lobbyorganisationen och dess ledning har kritiserats för misslyckanden, dubiös etik och korruption.[33]
