Abstract: In one embodiment, techniques include receiving, by a computing device associated with a payment service system, a request to create a blockchain-enforced contract corresponding to a new transaction between a merchant and a customer. Techniques include generating, based on analysis using machine-learned models of a transaction history associated with the merchant, a condition of the blockchain-enforced contract requisite for completion of the new transaction. Techniques includes generating the blockchain-enforced contract including the condition. Techniques include providing the blockchain-enforced contract to nodes in a blockchain network. Techniques include creating a blockchain transaction addressed to the blockchain-enforced contract and including information regarding the condition. Techniques include providing the blockchain transaction to the nodes. Techniques include receiving confirmation that the nodes have validated the blockchain transaction.

Abstract: In one embodiment, techniques include receiving, from a device associated with a merchant, a request to create blockchain-enforced contract corresponding to a new transaction between the merchant and a customer. Techniques include generating a condition of the blockchain-enforced contract requisite for completion of the new transaction. Techniques include receiving a selection of at least one option for determining that the condition is satisfied. Techniques include generating the blockchain-enforced contract and providing the blockchain-enforced contract to one or more nodes in the blockchain network. Techniques include receiving an input comprising information regarding the condition, creating a blockchain transaction addressed to the blockchain-enforced contract and sending the blockchain transaction to nodes in the blockchain network. Techniques include transferring a corresponding to the new transaction from an escrow account to a merchant account.

Abstract: In one embodiment, a method includes receiving one or more selected options for one or more of multiple contract conditions generated based on transaction information associated with a request to create a blockchain-related invoice and generating instructions for a blockchain-enforced contract based on the transaction information and the one or more selected options. The instructions for the blockchain-enforced contract correspond to a first nested contract including a first contract condition required for a transfer of a value and a second nested contract including a second contract condition required for at least a partial reversal of the transfer of the value. The method also includes, in response to receiving an input regarding the second contract condition, cause the instructions for the blockchain-enforced contract to be executed on a blockchain network.
