METHODS AND SYSTEMS FOR FACILITATING SHARING OF TOKENS IN BLOCKCHAIN TRANSACTIONS

Resumen de: US2025078050A1

Methods and systems are presented for providing a framework for facilitating token sharing with contract issuers based on processing of smart contract transactions. The framework provides a mechanism for allowing one or more computer nodes within a blockchain network to opt-in to a token sharing agreement with a contract issuer and a mechanism for an opted-in computer node to share tokens with the contract issuer in a decentralized manner. When a computer node has opted-in to the token sharing agreement, the computer node, by executing a smart contract, performs a set of computer procedures that is non-productive to the processing of the smart contract transaction. The execution of the set of non-productive computer procedures provides an additional amount of processing fee based on the processing of the smart contract transaction. The computer node then transfers a portion of the additional amount of processing fee to an account of the contract issuer as part of the processing of the smart contract.
