Secure storage and/or transfer of distributed ledger token through a possession token storing a private key controlling the ledger token

Abstract

In one embodiment, a method may include generating a first public-private key pair having a public key usable as a public address of the ledger token of a distributed ledger network and a private key usable to transfer the ledger token of the distributed ledger network. The method may verify that a ledger transaction occurred. The method may include generating a possession token storable in physical memory and having a state indicated by a state indicator, where the state of the possession token evolves upon transfer between two computing devices over a network. The method may include cryptographically associating the ledger token and the possession token through incorporation of the public address into data generating the state indicator of the state of the possession token. The method may include encrypting the private key to form an encrypted private key and storing the encrypted private key in the possession token.
