Abstract
The invention relates to the fields of tokenisation, blockchain, and smart contract technologies. Provided herein are a computer-implemented method and system which use a computer-based repository to store a contract and control the visibility and/or performance of the contract. A transaction is broadcasted to a blockchain, the transaction comprising i) at least one unspent output (UTXO) and ii) metadata comprising an identifier indicative of the location where the contract is stored. The contract is then renewed or rolled on by generating a new key using data relating to a previous key associated with the contract, generating a script comprising the new key, the location of the contract and a hash of the contract, and paying an amount of currency to the script. Functionalities provided or disclosed herein enable authorised parties to view a source (or existing) contract by means of its connection with the renewed or rolled on contract.
