När användare A överför en summa till användare B ger A upp sitt ägande genom att lägga till B: Resten av noderna i nätverket validerar sedan de kryptografiska signaturerna och summan av transaktionen innan de accepterar den.

Data lagras permanent i bitcoinnätverket i s. 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. Det här är den mekanism som gör att nya bitcoin tillkommer i bitcoinnätverket, och mekanismen kallas "brytning" jfr Guldbrytning.

Användare som vill göra en transaktion kan frivilligt välja att betala en transaktionsavgift. Transaktioner där transaktionsavgift har betalats kommer följaktligen att prioriteras av noderna och processas därför oftast snabbare än övriga transaktioner.

Bitcoinekonomin är fortfarande väldigt liten relativt andra etablerade ekonomier och mjukvaran är fortfarande i betastadiet.

Det finns heller ingen centralbank som kontrollerar penningmängden genom att justera styrräntan. Den här typen av transaktioner innebär dock att det är omöjligt att reversera en transaktion.

Bitcoinklienten 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.

Den totala mängden bitcoin ökar kontinuerligt men kommer aldrig att överstiga 21 miljoner i antal. 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. Jag misstänker att du även kommer att kunna lägga till lagstiftare till den listan inom kort.
