Abstract

The disclosed technology relates to assessing and securing credit risk using creditworthiness tokens issued in a blockchain network responsive to particular financial events. An exemplary blockchain node device may store an issuance smart contract associated with an identity and including a first wallet address and allocation parameters. An event query may be sent to an oracle device external to the blockchain network. The event query may include the identity. Event data associated with the identity may then be received from the oracle device in response to the event query. A number of creditworthiness tokens is determined based on an application of the allocation parameters to the event data. The determined number of creditworthiness tokens is then allocated to the identity via the first wallet address. Thereafter, the creditworthiness tokens can be transferred or collateralized, e.g., and can represent creditworthiness for the identity across financial institutions.

Claims20

Dependent claims

A blockchain node device in a blockchain network, the blockchain node device comprising:

one or more processors;
and
memory in communication with the one or more processors and storing instructions that, when executed by the one or more processors, are configured to cause the blockchain node device to:
store an issuance smart contract associated with an identity and comprising a first wallet address, one or more execution timing parameters, and one or more allocation parameters;
send at a time determined according to the one or more execution timing parameters an event query to an oracle device external to the blockchain network, wherein the event query comprises the identity;
receive event data associated with the identity from the oracle device in response to the event query, wherein the event data comprises one or more event parameters associated with financial activity associated with the identity and reported to the oracle device;
determine a number of creditworthiness tokens based on an application of the allocation parameters to the one or more event parameters;
and
mint each of the number of creditworthiness tokens within the blockchain network and allocate the minted number of the creditworthiness tokens to the identity via the first wallet address.

A blockchain node device, comprising:

a processor;
and
memory in communication with the processor and storing an issuance smart contract that, when executed by the processor, is configured to cause the blockchain node device to:
send a token query to an oracle device at a time determined according to one or more execution timing parameters defined in the issuance smart contract, wherein the oracle device is external to a blockchain network hosting the issuance smart contract and the token query comprises an identity identified in the issuance smart contract;
receive from the oracle device a number of creditworthiness tokens in response to the token query, wherein the number of creditworthiness tokens is determined based on event data for a financial transaction reported to the oracle device and associated with the identity;
and
allocate the number of creditworthiness tokens to the identity via a first wallet address in the blockchain network and identified in the issuance smart contract.
