9. The computer-implemented method of claim 1 , wherein adding the smart contract and the data set comprises:
obtaining a prior record in the immutable distributed ledger;
generating a hash of the prior record;
generating a new record comprising the hash of the prior record and the data set; and
adding the new record to the immutable distributed ledger.
10. The computer-implemented method of claim 1 , further comprising:
receiving a second smart contract from the third-party for a second designated party and a subset of the data set;
transmitting, to the network of nodes, a second request to add the second smart contract and the subset of the data set to the immutable distributed ledger;
receiving a new digital signature from the third-party;
receiving a digital signature from the second designated party;
validating the second smart contract, the new digital signature from the third-party, and the digital signature from the second designated party; and
adding the second smart contract and the subset of the data set to the immutable distributed ledger.
11. A system comprising:
a computing device comprising at least one physical processor; and
physical memory comprising computer-executable instructions that, when executed by the at least one physical processor, cause the computing device to:
receive a smart contract from a third-party for a designated party and a data set that includes data collected by the designated party from at least one targeted entity, wherein the smart contract includes a rule to check a permission status from the at least one targeted entity to use the collected data;
transmit, to a network of nodes, a request to add the smart contract and the data set to an immutable distributed ledger;

receive a digital signature from the designated party;
validate the smart contract, the digital signature from the third-party, and the digital signature from the designated party, wherein validating the smart contract includes processing the rule; and
in response to validating the smart contract, the digital signature from the third-party and the digital signature from the designated party, add the smart contract and the data set to the immutable distributed ledger.
12. The system of claim 11 , wherein the digital signature from the third-party is an attestation that the data set is legal and ethical and wherein the digital signature from the designated party is an attestation that the data set is legal and ethical.
13. The system of claim 11 , wherein the data set comprises personally identifying information and wherein the computer-executable instructions further cause the computing device to:
obtain a public key of the third-party;
obtain a public key of the designated party; and
encrypt the data set with the public key of the third-party and the public key of the designated party.
14. The system of claim 13 , wherein the computer-executable instructions further cause the computing device to:
obtain a public key of a party granted access to the data set; and
encrypt the data set with the public key of the party granted access to the data set.
15. The system of claim 11 , wherein the smart contract comprises a hash of external data used to build the data set.
