Yeah, at a cost of several million dollars per year of burned power. You'll find the less BTC someone owns the less likely they are to bring up non-arguments like "more hashes = more security!" Let's stop pretending there isn't room to innovate.
- DennisP 12y agoI wouldn't say those are non-arguments, just not conclusive arguments. Vitalik of Ethereum brings up the nothing-at-stake problem, in the context of proposing a solution: http://blog.ethereum.org/2014/01/15/slasher-a-punitive-proof-of-stake-algorithm/ http://blog.ethereum.org/2014/01/15/slasher-a-punitive-proof...
- jabgrabdthrow 12y ago"more hashes != more security" is true even if POS does not work (or rather, security scales sublinearly with hashes - economies of scale + diminishing returns on value of security). Nothing-at-stake is solved by DPOS, the ethereum team lags behind POS development by a few months it seems (they just mentioned using TAPOS a few weeks ago when the inventor has moved past it a few months ago).
- DennisP 12y agoWhat are DPOS and TAPOS?
- kolinko 12y agoDPOS = Delegated Proof of Stake. Owners of the majority of the stake (stake = all the coins) designate a limited set of servers to handle the blockchain operations. Thanks to this, there can be just 100 nodes interacting very quickly with each other and yet just as trustworthy - if not more - as the current bitcoin system.
