This is known as the "nothing at stake" problem and is solved at this point: just require a deposit for mining and treat it as a bounty for proving someone tried to mine on more than one continuation of the PoS blockchain. The kicker is part of the deposit is burned to avoid shenanigans of someone claiming the bounty on theirself and not having to suffer any consequences.
- nullc 10y agoThe above paper discusses that 'solution' (it isn't one.). The system remains circular, and participants can still grind for alternative histories which grant them more control over time.
- rocqua 10y agoHow would anyone get such a proof? Seems like mining would need to be collaborative, with no possibility of choosing the collaborators.
