Secure bitcoin by signing blocks as trusted?

[timeofmind]

This relates to my idea from Alt-Coin (ie. spam board):

TrustCoins:

I didn't think the idea belonged here because it is a totally different model than mining and clearly bitcoin could not ever change over to it exclusively, but...

I'm thinking it could be partially implemented as a "soft" addition to bitcoin protocol (ie. for informational purposes but not honored) as a secondary option against future attacks. Ie. if bitcoin was to at least build a network of trusted miners and each miner (pool) who adds blocks to the chain was to also add their signature to that block, it could potentially be used to blacklist a future attack and to select the chain of the most blocks with trusted signatures.

it seems both redundant and antithetical

Ya... well, was thinking just as failover in case of a worst-case senario.... but you are right. Just not for bitcoin. I guess if an entity takes over the blockchain, we are just screwed.
