Abstract
Methods and systems for registering identity of a mining node on a blockchain in a blockchain network. The methods may include creating a validity-check transaction having a first output controlled by the mining node and containing a miner identifier and propagating the validity-check transaction on the blockchain network. The methods may further include mining, by the mining node, a new block containing a generation transaction, wherein the generation transaction includes an information field that contains the miner identifier and a reference to the validity-check transaction. Another node may validate identity by receiving the miner identifier and the reference to the validity-check transaction, retrieving the validity-check transaction to confirm it contains the miner identifier, and determining that the first output is an unspent transaction output.
