Abstract
Provided is a system and method for implementing remote trust services for blockchain. In one example, the method may include one or more of retrieving block content from a portion of a blockchain via an application programming interface (API), in response to a triggering event being detected, calling an off-chain trust service to sign the retrieved block content, receiving accreditation results of the retrieved block content from the off-chain trust service, the accreditation results comprising an indication of whether the retrieved block content has been successfully signed, and writing the received accreditation results to a block within the blockchain.
Claims20
A computing system comprising:
- a memory storing program instructions;
- and
- processor coupled to the memory and configured to execute the program instructions, wherein when executed the program instructions cause the processor to:
- retrieve block content from a portion of a blockchain via an application programming interface (API), in response to a triggering event,
- call an off-chain trust service to sign the retrieved block content,
- receive accreditation results of the retrieved block content from the off-chain trust service, where the accreditation results comprise an indication of whether the retrieved block content has been successfully signed, and
- write the received accreditation results to a block within the blockchain.
A method comprising:
- retrieving block content from a portion of a blockchain via an application programming interface (API), in response to a triggering event being detected;
- calling an off-chain trust service to sign the retrieved block content;
- receiving accreditation results of the retrieved block content from the off-chain trust service, the accreditation results comprising an indication of whether the retrieved block content has been successfully signed;
- and
- writing the received accreditation results to a block within the blockchain.
A non-transitory computer-readable medium comprising instructions which when executed by a processor cause a computer to perform a method comprising:
- retrieving block content from a portion of a blockchain via an application programming interface (API), in response to a triggering event being detected;
- calling an off-chain trust service to sign the retrieved block content;
- receiving accreditation results of the retrieved block content from the off-chain trust service, the accreditation results comprising an indication of whether the retrieved block content has been successfully signed;
- and
- writing the received accreditation results to a block within the blockchain.
