blog-dshr-org-9557		DSHR's Blog: Alternatives To Proof-of-Work			.html	text/html	10138	743	70	The main approach to replacing PoW with something equally good at preventing Sybil attacks but less good at cooking the planet has been PoS, but a recent entrant using Proof-of-Time-and-Space (I'll use PoTaS since the acronyms others use are confusing) to waste storage has attracted considerable attention. In PoW as implemented by Nakamoto, the probability of a winning the next block is proportional to the number of otherwise useless hashes computed — Nakamoto thought by individual CPUs but now by giant mining pools driven by warehouses full of mining ASICs. The idea of PoS is that the resource being wasted to deter Sybil attacks is the cryptocurrency itself. The fact that Ethereum includes a Turing-complete contracting system complicates things further, as it makes certain kinds of collusion much easier without requiring trust, and creates a large pool of stake in the hands of decentralized entities that have the incentive to vote with the stake to collect rewards, but which are too stupid to tell good blockchains from bad.	./cache/blog-dshr-org-9557.html	./txt/blog-dshr-org-9557.txt
