Weighted source data secured on blockchains

A system for secure management of evaluation data, the system comprising:

• one or more processors;
• and
• one or more memory devices in communication with the one or more processors, the memory devices having computer-readable instructions stored thereupon that, when executed by the processors, cause the processors to perform a method for secure management of evaluation data comprising:
• receiving an evaluation value from a source entity, the evaluation value relating to an evaluation entity;
• defining entries for one or more source entities in trusted source data secured in one or more data blocks on a blockchain;
• searching the trusted source data secured in the data blocks on the blockchain for an entry corresponding to the source entity;
• and
• if the entry corresponding to the source entity is found in the trusted source data:
• obtaining the evaluation value for the evaluation entity from the blockchain,
• calculating a new evaluation value for the evaluation entity, and
• securely committing the new evaluation value for the evaluation entity to a new data block on the blockchain.

A computer storage medium having computer executable instructions stored thereon which, when executed by one or more processors, cause the processors to execute a method for secure management of evaluation data comprising:

• receiving an evaluation value from a source entity, the evaluation value relating to an evaluation entity;
• defining entries for one or more source entities in trusted source data secured in one or more data blocks on a blockchain;
• searching the trusted source data secured in the data blocks on the blockchain for an entry corresponding to the source entity;
• and
• if the entry corresponding to the source entity is found in the trusted source data:
• obtaining the evaluation value for the evaluation entity from the blockchain,
• calculating a new evaluation value for the evaluation entity, and
• securely committing the new evaluation value for the evaluation entity to a new data block on the blockchain.
