DECENTRALISED DIGITAL ASSET ARCHIVE

Abstract: a method of storing storage units representing digital assets into a decentralised repository arranged in a peer-to-peer network comprising a plurality of peer computing systems, to create an archive of the digital assets, comprising steps of, for each new storage unit being submitted to the archive by a submitting peer computer system: determining a specific quantity of stored existing storage units, each of which the new storage unit is to be cryptographically linked to, where the existing storage units have been previously submitted to the archive; selecting specific ones of all of the existing storage units up to the received specific quantity of stored existing storage units, where the selection has been made from existing storage units stored by specific ones of the peer computing systems; performing cryptographic processing by taking as inputs to such cryptographic processing, the selected specific existing storage units and the new storage unit, and obtaining a result of such cryptographic processing; adding the result into the new storage unit; and distributing the new storage unit to a plurality of peer computing systems, thereby adding the new storage unit to the decentralised repository.
