Network access control based on distributed ledger

A method of controlling system access, the method comprising:

• capturing, by a plurality of nodes of a computer network, information describing requested data transactions in the computer network;
• constructing, by at least some of the plurality of nodes, transaction blocks for a distributed ledger, each of the transaction blocks comprising information describing one or more of the requested data transactions;
• publishing, by the at least some of the plurality of nodes, the transaction blocks to others of the plurality of nodes;
• adding, by the plurality of nodes receiving the transaction blocks, those of the transaction blocks not including a disallowable requested data transaction to copies of the distributed ledger;
• and
• approving, by one or more arbitrator nodes of the plurality of nodes, those of the requested data transactions represented in transaction blocks added to the copies of the distributed ledger by a consensus of the plurality of nodes.

A non-transitory computer-readable storage medium storing instructions that, when executed by one or more processors of an access control system, cause the access control system to perform operations comprising:

• capturing, by a plurality of nodes of a computer network, information describing requested data transactions in the computer network;
• constructing, by at least some of the plurality of nodes, transaction blocks for a distributed ledger, each of the transaction blocks comprising information describing one or more of the requested data transactions;
• publishing, by the at least some of the plurality of nodes, the transaction blocks to others of the plurality of nodes;
• adding, by the plurality of nodes receiving the transaction blocks, those of the transaction blocks not including a disallowable requested data transaction to copies of the distributed ledger;
• and
• approving, by one or more arbitrator nodes of the plurality of nodes, those of the requested data transactions represented in transaction blocks added to the copies of the distributed ledger by a consensus of the plurality of nodes.
