RE: decentralized network security
The 51% attack, or control over the network by a state or group of actors, basically destroys the integrity of the blockchain, as this group can now decide to move money from any account, restrict transactions, etc.
The more likely a 51% attack can occur (via centralized systems) then the less secure we can call that network.
- hobofan 9y ago> as this group can now decide to move money from any account That's not accurate. They can double-spend, which can have equally bad effects, but without a way to forge transaction signatures (which is only possible with a broken cryptohash function), they can't just drain accounts.
