Certificate Reissuance for Upgraded Blockchain Smart Contracts on Blockchain Cybersecurity Platforms

One or more computer-readable non-transitory storage media embodying software that is operable when executed to:

• receive, by a certificate authority, a request to reissue a certificate for a smart contract on a first blockchain network, wherein an original certificate was previously issued for the smart contract;
• determine, by a certificate authority, that the smart contract is an upgradeable smart contract and that the smart contract was modified after the original certificate was issued or that the original certificate was revoked;
• receive, by the certificate authority, in a development environment, a copy of updated source code associated with an updated version of the smart contract;
• determine, by the certificate authority, whether the copy of updated source code satisfies one or more security criteria;
• receive, by the certificate authority, an indication that the updated smart contract was deployed on the first blockchain network;
• determine, by the certificate authority, that the updated smart contract deployed on the first blockchain network matches the copy of updated source code in the development environment;
• and
• issue, by the certificate authority, a reissue certificate for the updated smart contract based on the determination that the updated smart contract deployed on the first blockchain network matches the updated source code.

A computing system comprising:

• one or more processors;
• and a non-transitory memory coupled to the processors comprising instructions executable by the processors, the processors operable when executing the instructions to:
• receive, by a certificate authority, a request to reissue a certificate for a smart contract on a first blockchain network, wherein an original certificate was previously issued for the smart contract;
• determine, by a certificate authority, that the smart contract is an upgradeable smart contract and that the smart contract was modified after the original certificate was issued or that the original certificate was revoked;
• receive, by the certificate authority, in a development environment, a copy of updated source code associated with an updated version of the smart contract;
• determine, by the certificate authority, whether the copy of updated source code satisfies one or more security criteria;
• receive, by the certificate authority, an indication that the updated smart contract was deployed on the first blockchain network;
• determine, by the certificate authority, that the updated smart contract deployed on the first blockchain network matches the copy of updated source code in the development environment;
• and
• issue, by the certificate authority, a reissue certificate for the updated smart contract based on the determination that the updated smart contract deployed on the first blockchain network matches the updated source code.
