  • Publication number: 20210103576
    Abstract: The disclosed systems, structures, and methods are directed towards for processing a lock request by a master node to access a shared data object in a database located at a remote location comprising identifying, in the master node, a category of the lock request. If the lock request is for a self-compatible lock, determining a value of a counter associated with the master node and with one or more other master nodes, and if the value of the counter is zero, locally granting the lock request. If the value of the counter is greater than zero, forwarding the lock request to a global lock manager (GLM), and if the lock request is for a heavy-conflicting lock, forwarding the lock request by the master node to the GLM.

  • Publication number: 20210014071
    Abstract: This disclosure relates to anonymous transactions based on ring signatures. In one aspect, a method includes receiving a remittance transaction. The remittance transaction is generated by a client device of a remitter by assembling unspent assets in an account corresponding to the remitter and masked assets in an account corresponding to a masked participant. Key images are obtained from a linkable spontaneous anonymous group (LSAG) signature of the remittance transaction. Values of the key-images are based on a private key, a public key, and unspent assets of the remitter. The LSAG signature is verified. The LSAG signature is generated by the client device of the remitter based on the private key and the public key of the remitter, and a second public key of the masked participant. The remittance transaction is executed when a transaction execution condition is met.
