We claim:
1. A system for assessment of a risk score for a non-fungible token
transacted on a blockchain comprising:
a blockchain capable of implementing smart contracts for the creation, storing
and transaction of non-fungible tokens;
a processor-based server in electronic communications with the blockchain;
a database in electronic communications with a processor-based server
capable of storing and retrieving data;
the processor-based server configured to: 10
receive a request for assessment of a specific non-fungible token on the
blockchain;
scan the blockchain to identify blocks within the blockchain containing
a smart contract for the specific non-fungible token;
retrieve metadata embedded within the identified blocks containing a
smart contract for the specific non-fungible token;
derive an ownership history of the specific no-fungible token from the
retrieved metadata;
scan the blockchain to identify a block within the blockchain
containing the last transaction for the specific non-fungible token;
retrieve smart contract code from the identified block containing the
last transaction for the specific non-fungible token;
generate a provenance score based on the derived ownership history of
the specific non-fungible token;
generate a smart contract score based on the retrieved smart contract
code for the specific non-fungible token;
generate a permanence score based on the retrieved smart contract
code for the specific non-fungible token; and
generate a comprehensive risk score for the specific non-fungible
token based on the generated provenance score, smart contract score, and permanence 30
score for the specific non-fungible token.
2. The system for assessment of claim 1 wherein the processor-based
server is further configured to:
input the derived ownership history of the specific non-fungible token
into a provenance score model implemented by the processor-based server; and
generate the providence score using the provenance score model.
3. The system for assessment of claim 1 wherein the processor-based
server is further configured to:
input the retrieved smart contract code for the specific non-fungible
token into a smart contract score model implemented by the processor-based server;
and
generate the smart contract score using the smart contract score model.
4. The system for assessment of claim 1 wherein the processor-based
server is further configured to: 15
input the retrieved smart contract code for the specific non-fungible
token into a permanence score model implemented by the processor-based server; and
generate the permanence score using the permanence score model.
5. The system for assessment of claim 1 wherein the processor-based
server is further configured to:
input the generated providence score, the smart contract score, and the
permanence score into a comprehensive risk score model implemented by the
processor-based server; and
generate the comprehensive risk score using the comprehensive risk score model.
6. The system for assessment of claim 1 wherein the provenance score is
reflective of the ownership history of the specific non-fungible token.
7. The system for assessment of claim 1 wherein the permanence score is
reflective of how the retrieved smart contract code references the underlying asset of
the specific non-fungible token.
8. The system for assessment of claim 1 wherein the smart contract score
is reflective of code-related risk associated with the specific non-fungible token.
