The disclosure relates to, among other things, systems and methods for facilitating the secure recording of assertions made by entities tied to identities. Embodiments of the disclosed systems and methods may allow users to make non-revocable, difficult to forge, cryptographic assertions tied to their identities through the posting of entries in an immutable ledger. In certain embodiments, a user's cryptographic assertions may be preceded by ledger entries which feature certificates from trusted authorities that tie the keys used for making assertions to the user's identity. Further embodiments provide for a mechanism for disabling further entries posted under a user's key, either automatically or at the user's initiation.

A method for managing a trusted ledger performed by a first trusted ledger management system, the first trusted ledger management system comprising a processor and a non-transitory computer-readable storage medium storing instructions that, when executed by the processor, cause the first trusted ledger management system to perform the method, the method comprising:
The method of claim 19, wherein the first entry further comprises a signature generated using at least the first indication of the authorization relating to the use of the user deciphering key and an enciphering key of the first trusted authority corresponding to the deciphering key of the first trusted authority.
The method of claim 19, wherein the first trusted authority is associated with a second trusted ledger management system.
The method of claim 19, wherein the first indication comprises at least one restriction associated with the user deciphering key relating to its authorization for use to record entries in the trusted ledger.
The method of claim 19, wherein the first message comprises an electronic file.
The method of claim 19, wherein the first message comprises a hash value.
The message of claim 19, wherein the identity associated with the user system comprises at least one of a username, a user address, and user contact information.
The method of claim 19, wherein the second entry is recorded in a location in the trusted ledger after the first entry.
The method of claim 19, wherein the method further comprises:
