METHOD AND SYSTEM FOR DIRECTING AN EXCHANGE ASSOCIATED WITH AN ANONYMOUSLY HELD TOKEN ON A BLOCKCHAIN

Resumen de: EP4415308A2

The invention provides a method and corresponding system for controlling the generation of a blockchain transaction, and/or the recipient of a transaction output. It can also be used to control and record the ownership of an asset represented on the blockchain without the need for a separate registry of ownership. The ownership and transfers thereof can be handled and recorded without the need for knowledge of the parties involved or their identities. According to one embodiment, the method comprises the steps of identifying at least one transaction (Tx) on a blockchain which comprises: an unspent transaction output (UTXO) relating to a tokenised asset associated with an asset controller; and an input which spends an output from a previous transaction that is locked by a redeem script hash. For each identified transaction (Tx), an incomplete blockchain transaction is generated comprising: a first output comprising a copy of the redeem script hash; and a second output which is modifiable such that only the asset controller is able to specify a recipient for the second output. The incomplete blockchain transaction is communicated to the controller of the asset. the incomplete blockchain transaction is incomplete in that it is missing a required cryptographic signature. Thus, payment of income relating to the asset can be redirected by the controller to a destination of their choice.
