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.

A central service provider manages a blockchain network that writes the cryptographic hash of each executed transaction in a block to the blockchain network. For each executed transaction, the central service provider generates and transmits a transaction receipt such that a party can verify that the transaction was appropriately executed. Additionally, a party can check that the party's records are correct by providing transaction data describing details of transactions recorded in the party's records to the central service provider. The central service provider verifies the party's records by comparing the transaction data in the party's records to the blocks of transaction records in the blockchain network. In some scenarios, the central service provider may identify or receive an identification of a discrepancy arising from one or more transactions. The central service provider can reconcile the identified discrepancy.

The present invention relates to a blockchain method relating to geometric objects, a polygon storage method, an electronic device and a computer-readable storage medium. The blockchain token includes geometric data, and the geometric tokens are circulated through transfer, split, and merge. When geometric objects are of polygons representing the lands specified by the geographic location information, it is a suitable as blockchain for recording the transfer of land rights and interests. Except for the token representing the initial geometric objects, if the blockchain system limits all geometric objects in the blockchain to those generated by other tokens through transfers, splits or mergers, each polygon in an unspent token in the blockchain is unique and exclusive. If the initial polygon of the blockchain is one that represents the entire surface of the earth, the blockchain system can be used to record land circulation of the entire world.

A proportional feedback value is determined based on the redemption value and the market value. An integral feedback value is determined based on historical deviations of the redemption value. A redemption rate of the carbon reflex index is determined based on the proportional feedback value and the integral feedback value. It is determined that a difference between the market value and the redemption value is less than a threshold difference.
