1. A computer-implemented method comprising:
monitoring a computational task distribution system to detect a challenge to a proposer string provided by a proposer computer system in response to a request made by a requester computer system, the request specifying a computational task and a first digital asset associated with the request, the proposer string indicated by a hash of a solution to the computational task, the proposer string specifying a second digital asset referenced in an input to a proposer transaction associated with the proposer string, wherein the computational task distribution system is managed by a congress; and
as a result of detecting the challenge, at least:
resolving the challenge using a first blockchain network by at least selecting a solution from a set of solutions provided to the first blockchain network, the set of solutions at least including the proposer string; and
distributing digital assets from the first digital asset and the second digital asset to one or more parties of the computational task distribution system based at least in part on the solution, wherein the distribution of the digital assets is controlled by the congress under a threshold signature scheme.
