A computer-implemented method comprising receiving a first plurality of event requests each corresponding to a pending event, the pending event corresponding to a transfer of a digital asset between blockchains; appending a seller block instance to a blockchain for each of the first plurality of event requests, each seller block instance comprising a different seller set of event attributes of the first plurality of event requests; receiving a second plurality of event requests; appending a buyer block instance to the blockchain for each of the second plurality of event requests, each buyer block instance comprising different a buyer set of event attributes of the second plurality of event requests; and responsive to a seller set of event attributes from a seller block instance matching a buyer set of event attributes from a buyer block instance corresponding to the seller block instance, appending a match block instance to the blockchain.

Systems and methods for multi-entity blockchain-based event break prevention

A computer-implemented method comprising receiving a transaction request from a first computing device, the transaction request corresponding to a pending transaction between the first computing device and a second computing device and comprising a first set of transaction attributes; appending block instances to blockchains of the first and second computing devices, retrieving or receiving, from the second computing device, a second set of transaction attributes; when the first set of transaction attributes match, identifying a second blockchain associated with the pending transaction; automatically executing a protocol to compare the first set of transaction attributes with data stored onto a ledger of the identified second blockchain; and, in response to determining that the first set of transaction attributes complies with data of the ledger of the identified second blockchain, appending block instance to the blockchain comprising data corresponding to the transaction request to blockchains of the first and second computing devices.

Systems and methods for blockchain-based transaction break prevention

Systems and methods for novel uses and/or improvements to blockchains and blockchain technology. As one example, systems and methods are described herein for self-validating digital records that may be transferred in real-time through a cross-network registry. For example, in a conventional system, minting a token (e.g., a digital record) involves writing a self-executing program that defines the transfer rules of the digital record. Once the self-executing program is written, it is deployed on a blockchain, and the digital record is minted by publishing it to a blockchain.

Systems and methods for real-time recording of transfers of self-validating digital records across cryptographically secure networks using cross-network registries

Systems and methods for a bifurcated self-executing program that wraps a first self-executing program (e.g., a first smart contract) on a blockchain within a second self-executing program (e.g., a second smart contract), in which the second self-executing program enforces the digital signature requirement. The bifurcated self-executing program comprises a single compiled self-executing program that combines the first self-executing program and the second self-executing program.

Systems and methods for enforcing cryptographically secure actions in public, non-permissioned blockchains using bifurcated self-executing programs comprising shared digital signature requirements

A computer-implemented method comprising receiving a first event request corresponding to a pending event between a first computing device and a second computing device, the first event request comprising a first set of event attributes corresponding to the pending event; transmitting, each of a plurality of first subsets of event attributes to a different set of nodes; receiving a second event request corresponding to the pending event between the first computing device and the second computing device; and transmitting each of the plurality of second subsets of event attributes to a different set of the plurality of sets of nodes, wherein each of the plurality of sets of nodes compares the first subset of event attributes that the set of nodes receives with the second subset of event attributes that the set of nodes receives; and a block instance corresponding to the pending event to a blockchain.

Systems and methods for a bifurcated self-executing program that wraps a first self-executing program (e.g., a first smart contract) on a blockchain within a second self-executing program (e.g., a second smart contract), in which the second self-executing program enforces the requirement for particular security credentials/certificates. The bifurcated self-executing program comprises a single compiled self-executing program that combines the first self-executing program and the second self-executing program.
