Secure transfer between blockchains

A non-transitory computer readable storage medium comprising computer-executable intructions which, when executed by a processor, configure the processor to:

• join a congress by transferring one or more digital assets on a proof-of-work blockchain to a proof-of-work blockchain address associated with a congress pool having one or more other digital assets associated with other members of the congress;
• receive a private key share in response to joining the congress;
• detect a transaction of digital assets on the proof-of-work blockchain network to the proof-of-work blockchain address associated with the congress pool;
• cooperatively generate, with the other members of the congress, a valid signature for the transaction using the private key share in response to the detecting, based on an attribute included with the transaction, that the transaction is not a request to join the congress;
• and
• mint one or more digital assets on a proof-of-stake blockchain network in response to cooperatively generating the valid signature.

An electronic device comprising:

• an interface device;
• a processor coupled to the interface device;
• and
• a memory coupled to the processor, the memory having stored thereon computer executable instructions which, when executed, configure the processor to:
• join a congress by transferring one or more digital assets on a proof-of-work blockchain to a proof-of-work blockchain address associated with a congress pool having one or more other digital assets associated with other members of the congress;
• receive a private key share in response to joining the congress;
• detect a transaction of digital assets on the proof-of-work blockchain network to the proof-of-work blockchain address associated with the congress pool;
• cooperatively generate, with the other members of the congress, a valid signature for the transaction using the private key share in response to the detecting, based on an attribute included with the transaction, that the transaction is not a request to join the congress;
• and
• mint one or more digital assets on a proof-of-stake blockchain network in response to cooperatively generating the valid signature.
