A method for electing a leader in a blockchain network using a role-based consensus protocol includes generating a new block by a node in the blockchain network and computing an effective resources metric for the node based on a role of the node, resources of the node and a role-based weight profile for the resources of the node. Eligibility proof of the node is generated based on eligibility information that includes a blockheader of the new block, an identity of the node, a difficulty target, T, of the blockchain network, and the effective resources metric. The new block and the eligibility proof is broadcast to the blockchain network, to enable one or more other nodes in the blockchain network to verify eligibility of the node as a leader.
