In scenario when 51% coalition is censoring everyone else (block producers / validators that don't belong to coalition), the way out is via UASF - user-activate

In scenario when 51% coalition is censoring everyone else (block producers / validators that don't belong to coalition), the way out is via UASF - user-activated soft fork. This will cause slashing of attackers via "inactivity leak mechanism".

- dmichulke 4y agoThanks. To me it seems this would greatly damage the value of the assets (like the blockchain wars but for ETH) but yes, it can be recovered from. I think the problem here is centralization and this can be more easily avoided in PoW (because of energy costs rising a lot if all miners go in one place) instead of PoS (there are no physical restraints, so in theory all staking pools could be in Switzerland). So politically it's much harder to censor a more decentralized chain.

- dcolkitt 4y agoThe flip side is it's virtually impossible to hide a large-scale mining operation. The meatspace footprint is just gigantic. By contrast a validator node, even one securing billions of value, can run on consumer hardware sitting behind a VPN or TOR gateway.
