Consensus Protocols: PoW vs PoS By Bob Bonomo, CEO, Blockchain Innovation Group and President, Bob Bonomo LLC Blockchains are examples of distributed database technology, since they store transactional data across many computers rather than in a single, centralised system. In traditional centralised systems, where services run or data is stored on a single server, there is no concern about data synchronisation: all the data is simply present on that one machine. The distributed nature of blockchains improves data security, since the multiple copies of data make it extremely difficult and costly to tamper with or introduce forged transactions, while also increasing network reliability/uptime, since blockchains are resilient and continue to function if a manageable set of nodes become unavailable.
Proof of Work vs Proof of Stake What to Expect from Ethereum’s Protocol Shift It’s early days, but Ethereum, essentially a decentralised, blockchain-based, world computer, is changing its consensus protocol from Proof of Work to Proof of Stake. Julie Ros speaks with a few crypto traders about what the key differences are between the protocols and what they think of Ethereum’s bold move. Ethereum, the blockchain-based network that was proposed in 2013 and released in mid-2015 to provide a virtual “world computer” as the base layer for decentralised apps (DApps), has begun steps to move the methodology for confirming transactions from Proof of Work (PoW), whereby miners compete to unlock and upload blocks to the Ethereum blockchain, to a Proof of Stake (PoS) methodology, which establishes validators that stake an investment to participate.
