Resumen de: US2025245676A1

A process for segregating attributes of carbon credits including extracting pure CO2 equivalent from existing carbon credits, tokenizing the extracted pure CO2 equivalent and recording the tokenized pure CO2 equivalent on a distributed ledger. The process includes generating a quality certification mark with an embedded QR code when the tokenized pure CO2 equivalent is used for voluntary offsetting. The embedded QR code provides a link to the distributed ledger for independent verification of offsetting claims. The process includes segregating additional attributes from the existing carbon credits, wherein the additional attributes represent social or environmental benefits associated with carbon projects. The process includes tokenizing the segregated additional attributes and recording the tokenized additional attributes on the distributed ledger or a separate distributed ledger. The distributed ledger is a blockchain wherein the tokenized pure CO2 equivalent is represented as a smart contract on the blockchain.

REDUCING HIGH-RISK BLOCKCHAIN TRANSACTION BEHAVIOR ASSOCIATED WITH FIAT CURRENCY ACCOUNTS

Resumen de: WO2025155393A1

A computerized method monitors blockchain behavior associated with fiat currency accounts and generates notifications based on detected high-risk blockchain behavior. A transaction key associated with an on-ramp transaction is received. Based on fuzzy logic rules applied to transaction data of the on-ramp transaction and blockchain transaction data, a group of blockchain transactions are identified that are likely to be associated with the fiat currency account of the on-ramp transaction. A blockchain risk model is used with the identified group of blockchain transactions to determine that blockchain transaction behavior associated with the fiat currency account includes high-risk behavior and the financial institution (FI) of the on-ramp transaction is notified of the high-risk behavior, whereby the FI is enabled to take action to prevent future high-risk behavior. Thus, the method reduces the occurrence of costly malicious events using blockchain transactions and accounts are better secured against such events.
