Abstract

A computer implemented approach is proposed for computationally establishing joint custodial features to augment functionality of digital data objects recorded on a distributed ledger data structure. A specialized smart contract data object used as an improved digital wallet object is persisted on the distributed ledger data structure which provides a feature interface between a cryptographic wallet controlled directly by an individual, and a set of institutional computing systems and corresponding protocols. The specialized smart contract data object is configured to be a multi-signature joint custody safe data object, the specialized smart contract data object persisted as an interactive data object on a decentralized virtual environment that is configured to automatically execute code consistently and securely across nodes of a decentralized network whose ledger forms a Turing Complete state-machine based computing environment.

Dependent claims

A computer-implemented system configured for interoperability between a centralized computing system for joint custodial secure storage of digital assets and an automated smart contract data structure deployed and persisted on a distributed ledger of a decentralized computing system, the system comprising:

a computer processor coupled to non-transitory computer memory, the computer processor configured to:
receive a user's request to create a safe data object on the distributed ledger of the decentralized computing system for storage of the user's assets;
instantiate the automated smart contract data structure deployed on the distributed ledger for managing digital assets, the automated smart contract data structure comprising a list of pointers referencing a plurality of addresses, a mapping of transactions, a mapping of confirmations, and a user-configured number of required owner signatures for the transactions, wherein each of the addresses corresponds to an owner of a plurality of owners, wherein each of the required owner signatures comprises a digital signature created by the private key corresponding to each of the required owners;
generate a private key for each owner;
store the private key of each owner in a digital asset wallet associated with the owner;
configure risk controls in the automated smart contract data structure for the transactions;
provide an address of the safe data object to the user for receiving deposits;
receive a transfer of a digital asset by the user addressed to the address of the safe data object;
receive a request from the user to initiate a transaction of a digital asset from the safe data object to a target recipient at a target address, the transaction being added to the mapping of transactions;
prompt each of the required owners to apply a digital signature to the transaction using the private key corresponding to each of the required owners;
store a signature collected from each of the required owners in the mapping of confirmations;
confirm the mapping of confirmations contains all of the required owner signatures;
and
upon confirmation of the required owner signatures, transfer the digital asset to the target address.
