validatorselected

Validatorselected is a term used in blockchain and consensus protocol contexts to denote that a particular validator has been chosen to perform duties within a defined cycle, such as a slot, round, or epoch. The exact meaning and usage can vary by protocol and implementation, but it generally reflects a status or event indicating active assignment.

In proof-of-stake systems, validators are selected through a combination of stake, randomness, and protocol rules to participate in block production, validation, or attestation. When a validator is selected, systems may log or emit a signal labeled validatorselected, enabling clients, dashboards, and governance tools to track which validators have been assigned duties for the current interval. This selection process is typically time-bound, with roles rotating to ensure fairness and security.

The practical effect of being marked as validatorselected is that the assigned validator is expected to perform agreed-upon duties, such as proposing a block, validating transactions, or attesting to the validity of proposed blocks. Non-selected validators for the interval may remain idle or prepare for future rounds. Proper handling of validatorselected signals is important for network security, incentives, and penalties, since missed duties can lead to slashing or rewards adjustments in many systems.

Note that the term can appear in different forms across software clients or documentation, and its exact semantics depend on the protocol, client implementation, and log or API schema being used. See also: validator set, epoch, slot, attestation, and slashing.
