A blockmaker is a professional participant in a decentralized network on whose equipment a full copy of the blockchain is stored. Unlike ordinary users who work only with their own wallet, a blockmaker holds the entire chain of blocks in full and takes part in maintaining the network's operation.

Such participants play an important role in ensuring the decentralization and resilience of the system. Since full copies of the ledger are distributed across many independent nodes, the network continues to operate even when individual machines fail, and the data can be verified at any moment. The more participants in the network who store a full copy of the blockchain, the higher its reliability and resistance to interference attempts.

To operate, a blockmaker needs sufficient computing and disk resources, since the size of the blockchain constantly grows as new blocks are added. The activity of such participants is one of the elements of the infrastructure on which the entire decentralized accounting of transactions rests.
