Tag: Is proof of work better than proof of stake?

Ethereum is moving to a consensus mechanism called proof-of-stake (PoS) from proof-of-work (PoW). This was always the plan as it’s a key part in the community’s strategy to scale Ethereum via upgrades.

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. Crypto miners are at the core of that process.4 Mar 2022

Ethereum uses the Keccak-256 algorithm for its proof of work. This algorithm is related to the widely used SHA3 algorithm and has numerous technical advantages over the previously mentioned SHA-256 hashing algorithm, including enhanced collision resistance and preimage resistance.

Bottom Line. While proof of work is the most well-known blockchain consensus model, alternative consensus models like proof of stake might be more efficient since they can increase security, reduce energy use, and allow networks to more effectively scale.
