Claim 12:
13. A system for enhancing the performance of Distributed Ledger Technology, DLT networks, the system comprising a group of independent DLT networks connected by one or more communications networks, where at least one computing node of at least one of the DLT networks of the group, a first DLT network, comprises a processor configured to:
transmit a generated control block to one or more computing nodes of N other DLT networks of the group, wherein N being greater than or equal to 2, (N≥2), every Tc transactions of the first DLT network computing node, where Tc is a design parameter;
where a newly generated control block is transmitted only if it is a first control block transmitted or if it is determined that the previous control block has been validly transmitted;
and where each control block at least contains Proof of History information of the first network computing node;
receive, through the one or more communications networks, at least a confirmation message from one or more computing nodes of the N other DLT networks of the group, where a computing node of any of the other DLT networks transmits a confirmation message after having received the control block from the computing node of the first DLT network, validated it and added it to a distributed ledger;
where it is determined that the control block has been validly transmitted if the confirmation messages have been received from at least Kc different DLT networks of the group, where Kc is a design parameter of the first DLT network; and
every Tl transactions of the computing node of the first DLT network, where Tl is a design parameter of the first DLT network, transmitting a message to other DLT networks of the group requesting at least one previously transmitted control block, where said message is transmitted to the computing nodes of the DLT networks from which a confirmation message has been previously received for said at least one previously transmitted control block; and if, during a certain period of time, successful reply messages to the request are received from less than Kc different DLT networks, retransmitting said at least one previously transmitted control block to one or more computing nodes of N other DLT networks of the group.
