Methods and Devices for Registering and Authenticating Miner Identity in a Blockchain Network

A computing device configured to manage a public key infrastructure using a blockchain network to register identity of a mining node on a blockchain in the blockchain network, the computing device including:

• one or more processors;
• memory;
• and
• computer-executable instructions stored in the memory that, when executed by the one or more processors, cause the one or more processors to carry out a method of:
• creating a validity-check transaction having a first output controlled by the mining node and containing a miner identifier;
• propagating the validity-check transaction on the blockchain network;
• and
• 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.

A non-transitory computer-readable medium storing processor-executable instructions for managing a public key infrastructure using a blockchain network to register identity of a mining node on a blockchain in the blockchain network, the processor-executable instructions including instructions that, when executed by one or more processors, cause the one or more processors to perform a method of:

• creating a validity-check transaction having a first output controlled by the mining node and containing a miner identifier;
• propagating the validity-check transaction on the blockchain network;
• and
• 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.
