For the past couple of years there have been dozens of novel and interesting non-PoW approaches to achieving consensus, most based on some combination of trust and stake.

5 Oct 2017 While Ethereum is on its way to move consensus to proof of stake, Qtum and Tezos launched with a version of a proof of stake consensus protocol from the start. Interesting is that Tezos and Qtum go a step ahead and offers a decentralized way of governance to adopt any major upgrades to the used as authorization mechanism to control specific bitcoin tokens.

2 Nov 2017 As opposed to the PoW consensus protocol, the PoS protocol achieves consensus through stakers—sometimes referred to as minters, too—who “stake” their coins by locking them down in specialized wallets. With these stakers at work, mining will become redundant, meaning the Ethereum network This is a very good answer: The fundamental flaw of Proof of Work (PoW) is that the costs of attacking the system are equal to what is spent to run the system. High security thus can only be achieved at high operating costs. The idea is that the h 2 Jan 2017 A public chain is run by a large set of nodes which ensure the integrity of the network. In the case of a proof of work consensus algorithm (Bitcoin, Ethereum), miners compute new blocks which are verified by every full node on the network.
