Systems and methods for maintaining decentralized digital identities are disclosed. In an information processing apparatus for a relying party within a distributed ledger network and comprising at least one computer processor, a method for decentralized digital identity attestation verification may include: (1) receiving, from a relying party, an attestation verification request for a user; (2) retrieving a user decentralized identifier for the user; (3) retrieving an attestation issuer decentralized identifier for an attestation issuer; (4) validating the user decentralized identifier and the attestation issuer decentralized identifier; (5) verifying that the attestation has not been revoked; and (6) communicating that the attestation is valid to the relying party.

Systems and methods for distributed ledger-based settlement are disclosed. In one embodiment, a method may include: receiving settlement instructions from a first party providing a commodity and a second party providing cash; matching the settlement instructions; affirming the matched settlement instructions with the parties; a smart contact sending the affirmed settlement instructions to a commodity clearing bank; the smart contract receiving confirmation of a blockage of the commodity from the commodity clearing bank; the smart contact sending the affirmed settlement instructions to a cash clearing bank; the smart contract receiving confirmation of a blockage of the cash from the cash clearing bank; the smart contract executing the exchange of tokens for the commodity for tokens for the cash; and the smart contract writing the tokens for the cash to a wallet for the first party, and writing tokens for the commodity to a wallet for the second party.
