Secure storage and/or transfer of distributed ledger token through a possession token associated with the ledger token

A computer readable media that is physical and non-transitory storing computer readable instructions that when executed:

• generate a first public-private key pair comprising a public key usable as a public address of a ledger token of a distributed ledger network associated and a private key usable to transfer the ledger token of the distributed ledger network from the public address to a different public address;
• verify a ledger transaction occurring on the distributed ledger network meets a finality requirement based on a consensus algorithm of the distributed ledger network, the finality requirement with respect to at least one of (i) transferring the asset to the public address and (ii) associating the asset with the public address;
• generate a possession token storable in a memory and having a state of the possession token indicated by a state indicator that evolves upon a transfer between two instances of computing devices,
• wherein the state indicator is a state hash that is a hash value dependent on a transaction data associated with the transfer between the two instances of computing devices;
• and
• store the private key usable to transfer the ledger token of the distributed ledger network from the public address to the different public address.

A system comprising:

• a network;
• one or more computers comprising one or more processors and one or more memories comprising:
• a ledger key generation engine comprising computer executable instructions that when executed generates a public-private key pair comprising a private key and a public address,
• a possession key engine comprising computer executable instructions that when executed:
• generates a second public-private key pair referred to as a server overt key and a server covert key for exchange over the network for a client overt key to generate a shared secret;
• and
• receives as inputs the server overt key and the client overt key and generate the shared secret,
• a private key encryption module comprising computer executable instructions that when executed encrypts the private key with the shared secret,
• a set of computer executable instructions that when executed:
• transmit the public address over an encrypted communication channel, and
• verify a ledger transaction on a distributed ledger network to transfer a ledger token to a public key as the public address meets a finality requirement.
