Tracking subsea telecommunications asset capacity and spectrum

A system comprising:

• data processing hardware of a first entity;
• and
• memory hardware in communication with the data processing hardware, the memory hardware storing instructions that when executed on the data processing hardware cause the data processing hardware to perform operations comprising:
• generating a first asset token, the first asset token representing control, by the first entity, of a portion of a physical communication asset, the first asset token comprising:
• an unencrypted identity of the first entity;
• and
• an unencrypted location of the physical communication asset;
• publishing, to a distributed ledger, ownership of the first asset token;
• receiving, from a second entity, a request to control the portion of the physical communication asset represented by the first asset token;
• and
• in response to receiving the request:
• removing the first asset token from circulation on the distributed ledger;
• generating a second asset token, the second asset token representing control, by the second entity, of the portion of the physical communication asset, the second asset token comprising:
• the unencrypted identity of the first entity;
• an unencrypted identity of the second entity;
• the unencrypted location of the physical communication asset;
• contractual information encrypted by a data encryption key, the contractual information associated with transferring control of the portion of the physical communication asset from the first entity to the second entity;
• and
• the data encryption key encrypted by a public key associated with the second entity;
• publishing, to the distributed ledger, ownership of the second asset token;
• and
• transferring, using the distributed ledger, ownership of the second asset token to the second entity.
