Patent ID: 11210647

Abstract:
A transaction system based on a distributed peer-to-peer computer architecture, said system involving transactions generated by users by means of wallets and allowing the transfer of units of account by feeding inputs from outputs, each transaction (called downstream transaction) having an input directly or indirectly referring to an output of an upstream transaction (or several inputs each referring to an output of a respective upstream transaction) and having an output specifying the number of units of account and an address of a recipient.The system comprises means for connecting an input of a downstream transaction to an output of an upstream transaction as a function of matching rules between a code computed on all or part of the content of the downstream transaction and a check code contained in the upstream transaction, or conversely,The system further comprises means for propagating a contract, predetermined at an upstream transaction, to a downstream transaction having an input connected to the output of said upstream transaction, said contract being executable on a context for establishing allocation constraints of the output(s) of the downstream transaction, such allocation being authorized only if the constraints are met.
