Witness is a participant in blockchain networks responsible for validating and confirming transactions. They maintain ledger integrity by ensuring all transactions adhere to network rules and protocols. Witnesses are crucial for achieving decentralized consensus, often participating in governance and decision-making processes. In Delegated Proof of Stake (DPoS) systems, witnesses are elected by stakeholders to produce blocks. They play a key role in enhancing the security and reliability of the blockchain. Their involvement ensures the network remains decentralized and trustworthy, preventing fraud and double-spending.
