6 . The method of claim 5 , further comprising updating by the fourth agent a ledger based on the digitally signed transaction and the second verifiable proof.

7 . The method of claim 4 , wherein the entity-identifying information comprises at least one of a driver license, business license, passport, or social security card.

8 . The method of claim 3 , wherein the second verifiable proof comprises the locked credential.

9 . The method of claim 1 , wherein the at least one data point comprises at least one of a first name, last name, date of birth, credit card number, social security number, or passport number.

10 . The method of claim 1 , wherein the at least one requirement comprises at least one of a price, a service level agreement (“SLA”), or a policy.

11 . The method of claim 1 , wherein the entity comprises at least one of a user of the second agent or an organization associated with the user of the second agent.

12 . The method of claim 1 , wherein the first verifiable proof comprises a proof of payment.

13 . The method of claim 1 , further comprising:

transmitting by the second agent to the third agent the request to initiate the use of the service;

receiving by the second agent from the third agent the request for the at least one data point to initiate the use of the service;

transmitting by the second agent to the third agent the at least one requirement for fulfilling the at least one data point;

receiving by the second agent from the third agent the digitally signed transaction; and

transmitting by the second agent to the third agent the second verifiable proof.

14 . A digital system for transacting over a network comprising a first computing system comprising a first processor and a first computer readable medium comprising a first agent comprising first instructions executable by the first processor for operating on the first computing system, comprising a second computing system comprising a second processor and a second computer readable medium comprising a second agent comprising second instructions executable by the second processor for operating on the second computing system, and comprising a third computing system comprising a third processor and a third computer readable medium comprising a third agent comprising third instructions executable by the third processor for operating on the third computing system, the first agent operable to cause the first computing system to:
