Blockchain

The method of wherein determining the computational power devoted to the blockchain by the further node comprises one or more of:

• the identification of shares held by the further node relating to the solution of a cryptographic problem;
• the identification of a share verification contract (SVC);
• the determination of a hash rate of the further node;
• and
• the determination of the number of previous blocks proposed by the further node.

A computer-implemented method of configuring a blockchain, such that a node of the blockchain is arranged to and/or required to:

• determine a computational power devoted by a further node to a blockchain;
• determine, based on the determined computational power, a parameter relating to:
• the influence of the further node on a consensus mechanism of the blockchain;
• and/or
• a reward for the further node;
• and
• output a transmission to the second node of the blockchain in dependence on the parameter.

A computer-implemented method of outputting a transmission to a second node of a public consensus network, the method being performed by a first node of the public consensus network, the method comprising:

• determining a computational power devoted by a further node to a public consensus network;
• determining, based on the determined computational power, a parameter relating to:
• the influence of the further node on a consensus mechanism of the public consensus network;
• and/or
• a reward for the further node;
• and
• outputting a transmission to the second node of the public consensus network in dependence on the parameter.
