Method and system of mining blockchain transactions provided by a validator node

A validator node, the validator node comprising:

• a processor;
• memory storing at least part of a pool of unconfirmed transactions;
• a non-transitory processor-readable medium storing processor-executable instructions that, when executed by the processor, causes the processor to perform steps comprising:
• validating a set of unconfirmed transactions;
• identifying a set of mining nodes that participate in a blockchain;
• sending an invitation to the set of mining nodes;
• receiving an identifier from each mining node of the set of mining nodes;
• providing the set of mining nodes with the set of validated unconfirmed transactions in exchange for a token from each mining node of the set of mining nodes;
• returning the token to said one of the set of mining nodes and retaining the remaining tokens responsive to a miner at one of the set of mining nodes successfully mining a block containing the set of validated unconfirmed transactions;
• transferring, to each of the set of mining nodes, a modified token responsive to a miner at a node other than one of the set of mining nodes successfully mining a block before any of the set of mining nodes is able to mine a block containing the set of validated unconfirmed transactions;
• and
• passing control over the token to another node of the set of mining nodes when a miner at one of the set of mining nodes does not successfully mine a block containing the set of validated unconfirmed transaction.

A non-transitory processor-readable medium storing processor-executable instructions to process blockchain transactions, wherein the processor-executable instructions, when executed by a processor of a validator node, cause the processor of the validator node to perform steps comprising:

• validating a set of unconfirmed transactions;
• identifying a set of mining nodes that participate in a blockchain;
• sending an invitation to the set of mining nodes;
• receiving an identifier from each mining node of the set of mining nodes;
• providing the set of mining nodes with the set of validated unconfirmed transactions in exchange for a token from each mining node of the set of mining nodes;
• returning the token to said one of the set of mining nodes and retaining the remaining tokens responsive to a miner at one of the set of mining nodes successfully mining a block containing the set of validated unconfirmed transactions;
• transferring, to each of the set of mining nodes, a modified token responsive to a miner at a node other than one of the set of mining nodes successfully mining a block before any of the set of mining nodes is able to mine a block containing the set of validated unconfirmed transactions;
• and
• passing control over the token to another node of the set of mining nodes responsive to a miner at a node other than one of the set of mining nodes successfully mining a block before any of the set of mining nodes is able to mine a block containing the set of validated unconfirmed transactions.
