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.”
