Abstract
A method of creating, redeeming and transferring tokens associated with tokens on a peer-to-peer distributed ledger. The method includes including metadata associated with the token in a redeem script, wherein the redeem script is associated with a transaction of cryptocurrency on the peer-to-peer distributed ledger. One aspect of the invention provides a method of issuing and/or transferring a token, comprising the steps of generating a blockchain transaction (Tx) having an output (TxO) related to a quantity of cryptocurrency such as Bitcoin, and a hash of a redeem script. The redeem script comprises metadata which in turn comprises a token. The token is a representation of, or a reference to, a tokenised entity. The redeem script also comprises at least one (preferably two or more) public cryptographic keys. The metadata is provided in the redeem script at a location which is designated in the underlying blockchain protocol as a location for a cryptographic key.
