Transactions as proof-of-stake... referencing recent block hashes in your transactions to prevent reversing history too far. Dan's brainchild ;)
Do not use this post as information for making any important decisions. The only agreements I ever make are informal and non-binding. Take the same precautions as when dealing with a compromised account, scammer, sockpuppet, etc.

Vitalik on reddit:
QuoteThat's not quite what I said. I said that every pure PoS system, except a PoS system with trusted chain download sources, can always and forever be taken over by a 51% collusion of the genesis block allocation. If you're willing to accept that, then TaPoS-based systems plus slasher plus some kind of yet-undiscovered transaction aggregation protocol seem to be quite viable, albeit flimsier in certain ways.
Whats TaPoS in ethereum language?
