joining, by the requester node, a group through transfer of tokens to a public group address to become a group member, the group being associated with a threshold signature scheme for which the node controls a private key share, the transfer of tokens being made on a proof-of-work blockchain network;
issuing a request to the group to complete a work product;

constructing a transaction in response to receiving the proposal;
obtaining a solution to the work product, determining that no challenge has been proposed to the solution; and
