Abstract

The invention relates to blockchain technologies such as the Bitcoin ledger, and for the control and performance of secure, efficient exchanges conducted via the blockchain. It comprises tokenisation techniques and methods for embedding metadata in a blockchain transaction. It provides a computer implemented method for performing a transfer, the method comprising scanning entries in a distributed hash table (DHT) distributed across a first network, the DHT comprising a plurality of entries, each entry comprising an invitation to perform an exchange and a link to a transaction on a peer-to-peer (P2P) distributed ledger distributed across a second network, each invitation including metadata comprising an indication of entities to be exchanged and one or more conditions for the exchange; determining a match between a first set of metadata in a first invitation of a first entry from a first user and a second set of metadata in a second invitation of a second entry from a second user, the determining comprising: identifying a match between indications of entities to be exchanged in the first and second invitations; and identifying a match between one or more of the conditions of the first invitation and one or more of the conditions of the second invitation; generating a first exchange transaction; and broadcasting, over the second network, the first exchange transaction for inclusion on a P2P distributed ledger, wherein the first exchange transaction comprises: an indication of a first quantity of a cryptocurrency to be transferred; a first input provided from an output of a transaction on the P2P distributed ledger linked to the first entry; a first script, a first user private key associated with the first user, a first third-party private key associated with a first third-party, wherein the first script comprises: the first set of metadata, a first user public key associated with the first user, the first user public key being a cryptographic pair with the first user private key, and a first third-party public key pair associated with the first third-party, the first third-party public key being a cryptographic pair with the first third-party private key and a first output indicating a transfer of a first quantity of the first entity from the first user to the second user
