1. A computer-implemented method comprising:
joining a congress of a plurality of nodes by transferring, by a node operating in a proof-of-work blockchain network and in a proof-of-stake blockchain network, one or more digital assets to a congress pool having one or more other digital assets associated with other members of the congress, wherein joining the congress comprises adding to the proof-of-work blockchain a special transaction transferring the one or more digital assets to a group public address associated with the congress pool, wherein the special transaction transferring the one or more digital assets to the group public address is a request to join the congress, and wherein the node is an electronic device having a processor and a memory storing operations that are executable by the processor;
detecting, by the node, the special transaction of digital assets on the proof-of-work blockchain network transferring the one or more digital assets to the group public address associated with the congress pool, the special transaction satisfying determined criteria, the special transaction transferring the one or more digital assets to the group public address has the effect of locking the one or more digital assets of the special transaction against transfers other than by the congress pool; and
minting, by the node, one or more digital assets on the proof-of-stake blockchain network in response to detecting the special transaction, the digital assets on the proof-of-stake blockchain network and corresponding to the locked one or more digital assets.
