Delegation Transaction

Definition ∞ A Delegation Transaction involves assigning voting power or staking rights to another entity, known as a delegator, within a blockchain network. This process allows token holders to participate in network governance or secure the chain without running their own node. The delegator then uses the combined power to vote on proposals or validate transactions, sharing any earned rewards with the delegators. This mechanism promotes broader participation and decentralization.
Context ∞ The discussion surrounding delegation transactions frequently addresses the balance between network decentralization and the concentration of power among a few large delegators. A key situation involves debates over optimal reward structures and the potential for cartel formation among validators. Critical future developments include improvements in delegation interfaces and incentive designs aimed at encouraging a more distributed and active base of delegators.
