Post-commit validation in a distributed ledger

A method, comprising:

• receiving a request for performing a post-commit validation of a chain of blocks on a distributed ledger, the chain of blocks being encrypted using an encryption key;
• requesting cooperation from one or more auditor nodes associated with the distributed ledger, each auditor node comprising a partial secret of a decryption key corresponding to the encryption key;
• and
• in response to receiving partial secrets from a minimum threshold of auditor nodes, recovering the decryption key based on the received partial secrets, decrypting the chain of blocks based on the recovered decryption key, and validating content included within the chain of blocks.

A non-transitory computer readable medium comprising instructions, that when read by a processor, cause the processor to perform:

• receiving a request for performing a post-commit validation of a chain of blocks on a distributed ledger, the chain of blocks being encrypted using an encryption key;
• requesting cooperation from one or more auditor nodes associated with the distributed ledger, each auditor node comprising a partial secret of a decryption key corresponding to the encryption key;
• and
• in response to receiving partial secrets from a minimum threshold of auditor nodes, recovering the decryption key based on the received partial secrets, decrypting the chain of blocks based on the recovered decryption key, and validating content included within the chain of blocks.
