A decentralized open-source digital currency.
|Proof of Work (PoW)
|Public / Private / Permissioned
|All participants have access to all entries ever recorded.
|Topological ordering from the perspective of transaction outputs.
PoW is vulnerable to a “51% attack”. Whoever has 51 percent or more of the network’s computing power can manipulate the blockchain to their advantage.
Performance on public blockchains utilizing PoW are orders of magnitude less than permissioned or private blockchains running other consensus protocols.
