Fault tolerance

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

Performance on public blockchains utilizing PoW are orders of magnitude less than permissioned or private blockchains running other consensus protocols.
