Delegates

Delegates are regular wallets (addresses) which have registered themselves eligible to become a Delegate by a registration transaction. If a Delegate is among the top 51 highest voted (by staked ARK), it may run a forging Node, which produces a single block per round, awarding the Delegate 2 ARK + any transaction fees included in that block.

Genesis Delegates are the initial, virtualized Delegates. They were not registered nor voted in, and in the ARK mainnet has been replaced by actual Delegates a long time ago.

Endpoints

List All Delegates

You can obtain all Delegates through this paginated API. Note that all registered Delegates are returned in this response, not just the top 51 forging Delegates. If a Delegate Node is offline, it is still returned through this API; as the delegate resource is not concerned with the actual nodes, only with the on-chain registrations and wallets.

Retrieve a Delegate

You can query for a specific delegate by username, address, and public key; thus the following queries will result in an identical response. Note that public keys are always known for delegates, as they have previously transmitted a registration transaction. This is not the case for regular wallets.
