Bitcoin: A Peer-to-Peer Electronic

Cash System

Satoshi [email protected]

www.bitcoin.org

A purely peer-to-peer version of electronic cash

would allow onlinepayments to be sent directly

from one party to another without going through

afinancial institution.

Digital signatures provide part of the solution, but the mainbenefits are

lost if a trusted third party is still required to prevent double-

spending.We propose a solution to the double-spending problem using

a peer-to-peer network.The network timestamps transactions by

hashing them into an ongoing chain ofhash-based proof-of-work,

forming a record that cannot be changed without redoingthe proof-of-

work. The longest chain not only serves as proof of the sequence

ofevents witnessed, but proof that it came from the largest pool of CPU

power. Aslong as a majority of CPU power is controlled by nodes that

are not cooperating toattack the network, they'll generate the longest

chain and outpace attackers. Thenetwork itself requires minimal

structure. Messages are broadcast on a best effortbasis, and nodes

can leave and rejoin the network at will, accepting the longestproof-of-

work chain as proof of what happened while they were gone.

Internet. A Internet mudou o jeito que transferimos

informações. O Blockchain está transformando a

maneira como nós transferimos valor.”
