Proof-of-authority
Proof-of-authority is a blockchain consensus mechanism where a limited number of trusted validators are authorized to create new blocks and confirm transactions. Validators’ identities are known and verified, which reduces the need for energy-intensive computations. This system prioritizes speed and efficiency over decentralization, making it suitable for private or consortium blockchains. Validators are incentivized to act honestly, as misbehavior can damage their reputation. Proof-of-authority provides fast, secure, and reliable transaction processing for networks with trusted participants.
