- An alternative to Proof of Work is Proof of Stake (PoS), used by cryptocurrencies like Ethereum 2.0 and Cardano. Instead of relying on mining, PoS allows users to “stake” their coins as collateral to validate transactions and create new blocks.
- PoS is considered more energy-efficient than PoW because it doesn’t require large amounts of computational power, making it more environmentally friendly.
