Proof of authority (PoA) is an algorithm used with blockchains that delivers comparatively fast transactions through a consensus mechanism based on identity as a stake . The most notable platform using PoA is VeChain.
Read moreWhat is proof of work and proof of stake in blockchain?
Proof of Stake (POS) uses randomly selected miners to validate transactions. Proof of Work (POW) uses a competitive validation method to confirm transactions and add new blocks to the blockchain .

Blockchains don’t have a central gatekeeper, like a bank, to verify transactions. Instead, both Bitcoin and Ethereum, the two largest cryptocurrencies, rely on a consensus mechanism called “proof of work” to maintain a time-ordered ledger of transactions .4 Mar 2022

Ethereum will move from proof-of-work to proof-of-stake this summer , Vitalik Buterin has confirmed. The ETH 2.0 ‘Merge’ upgrade promises to cut transaction fees, increase coins ‘burned’ and improve congestion.6 Mar 2022
Read moreWill proof-of-work go away?
Over the next year, proof-of-work will be phased out in favour of Proof-of-stake (PoS) . The transition to proof-of-stake will also phase out mining from Ethereum.
