description In one embodiment, a distributed serial security network (SSN) includes a sequencer that receives a multi-fragmented transaction from a transaction client, assigns a commit timestamp (CTS) to the multi-fragmented transaction, and assigns the multi-fragmented transaction to at least two database fragments for execution. Verifier instances in each of the at least two database fragments determine an order of the multi-fragment transactions according to the assigned CTS and cooperate with each other to exchange local transaction verification values (e.g., [eta] and [pi] values of a serial secure network verification process) for the assigned multi-fragment transactions. The validator instances in each of the at least two database fragments each further perform max () and min () operations, such as the serial secure network validation process, on the received transaction validation value and a local transaction validation value to determine a final transaction validation value, and submitting or aborting the alloc
