Abstract
Techniques are described that enable client computer systems to request an attestation provider server to execute a given algorithm as identified by a decentralized algorithm identifier on the blockchain, using a specific data set. In some embodiments, the owners of the algorithms, data schemas, and data sets use their private key to sign/register each of these decentralized identifier structures, which includes a copy of the owner's public key. Ownership of these decentralized identifiers can be validated by verifying the digital signatures on the blockchain. In some embodiments, only the owner can replace or delete (retire) these identifiers by creating a cancellation transaction on the blockchain for each of these identifiers. In some scenarios, the decentralized identifier structures may include payment options for requesting the execution of an algorithm upon a given appropriate data set.
