A client may interact with the data enrichment environment to generate an enrichment smart contract and deploy the enrichment smart contract to the blockchain. The enrichment smart contract may comprise data indicating the enrichment inquiry. One or more solvers may interact with the data enrichment environment to submit proposed enrichment solutions based on the enrichment inquiry. One or more observers may interact with the data enrichment environment to review and vote on the proposed enrichment solutions. The data enrichment environment may evaluate the proposed enrichment solutions based on contract conditions. ## Claims ### Claim 1 A method comprising: generating, by a processor in electronic communication with a blockchain, an enrichment smart contract comprising a client ID, an inquiry ID, a first vendor detail, an enrichment request detail, and a contract condition;

a tangible, non-transitory memory configured to communicate with the processor, the tangible, non-transitory memory having instructions stored thereon that, in response to execution by the processor, cause the processor to perform operations comprising: generating, by a processor in electronic communication with a blockchain, an enrichment smart contract comprising a client ID, an inquiry ID, a first vendor detail, an enrichment request detail, and a contract condition; deploying, by the processor, the enrichment smart contract to the blockchain; receiving, by the processor, a proposed enrichment solution comprising a solver ID, a solution ID, the inquiry ID, a second vendor detail, and an enrichment solution detail corresponding to the enrichment request detail; and evaluating, by the processor, the proposed enrichment solution based on the contract condition, the first vendor detail, and the second vendor detail, wherein in response to the proposed enrichment solution passing the evaluation, a validated enrichment solution is generated. ### Claim 9 (depends on 8) The system of claim 8, further comprising receiving, by the processor, an enrichment solution validation vote corresponding to the proposed enrichment solution, the enrichment solution validation vote comprising an observer ID, the solution ID, the inquiry ID, and a vote, wherein the proposed enrichment solution is validated based on the vote. ### Claim 10 (depends on 8) The system of claim 8, further comprising: receiving, by the processor, an enrichment inquiry comprising a third vendor detail and a request detail;
