Definition ∞ Decentralized validators are independent entities that confirm and secure transactions on a blockchain network. These participants operate without central authority, verifying new blocks of transactions according to the network’s consensus mechanism, such as Proof of Stake. Their distributed nature enhances the network’s security and resistance to censorship. Each validator contributes to maintaining the integrity and immutability of the blockchain ledger.
Context ∞ The role of decentralized validators is a core topic in discussions about blockchain scalability and network security, particularly with the transition of major protocols to Proof of Stake. Debates concern the potential for validator centralization if staking power concentrates among a few large entities. Ongoing protocol upgrades often focus on increasing validator participation and geographic distribution to strengthen decentralization.
