Data quality control

A method, comprising:

• receiving, by a monitoring peer, data collection requirements from a model builder node;
• querying, by the monitoring peer, a blockchain of a plurality of blockchains for data sets that match the data collection requirements;
• providing, by the monitoring peer, the data sets to the model builder node to be tested;
• receiving, by the monitoring peer, a performance feedback on the data sets from the model builder node;
• and
• updating, by the monitoring peer, a smart contract associated with the data sets on the blockchain based on the performance feedback.

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

• receiving data collection requirements from a model builder node;
• querying a blockchain of a plurality of blockchains for data sets that match the data collection requirements;
• providing the data sets to the model builder node to be tested;
• receiving a performance feedback on the data sets from the model builder node;
• and
• updating a smart contract associated with the data sets on the blockchain based on the performance feedback.
