Cryptocurrencies operate on blockchain networks, where transactions are verified through consensus mechanisms. When you send cryptocurrency, your transaction must be validated by other participants in the network. There are different methods for achieving consensus:
- Proof of Work (PoW): Used by Bitcoin, this method requires miners (network participants) to solve complex mathematical problems to validate transactions and add them to the blockchain.
- Proof of Stake (PoS): Used by Ethereum 2.0 and other cryptocurrencies, PoS allows users who hold a certain amount of cryptocurrency to validate transactions and earn rewards. It’s considered more energy-efficient than PoW.
These consensus mechanisms ensure that the network is secure and that all transactions are legitimate.
