Abstract: Systems and methods of shared secret validation for a transaction to transfer an association of a digital asset represented in a distributed transactional database from an incumbent entity to a requesting entity, the digital asset having associated a probabilistic data structure encoding at least one digital hash of each of a plurality of secrets including the shared secret, and the transaction including a hash of the shared secret, including validating the transaction by comparing the hash of the shared secret in the transaction with the probabilistic data structure; and responsive to the validation, committing the transaction in the database to effect the transfer of association of the digital asset to the requesting entity.
