Proof of stake coins exist and work just fine. Tezos. Ethereum.
- runeks 6y agoProof-of-stake has different properties than proof-of-work. For example, given n different chains, proof-of-work (PoW) reaches consensus simply by choosing the chain with the most work — irrespective of block contents. Proof-of-stake (PoS), on the other hand, requires granting special meaning to a particular public key (in the first block) in order to reach consensus. So PoW reaches consensus without granting special meaning to any public key while PoS requires this in order to work.
