Claim 0:
1. A network system for handling fault tolerance in a blockchain enabled network system, comprising:
a computing system programmed or configured with at least one of a plurality of processors arranged as an active processor node in the network system;
at least one data storage device comprising a first ledger corresponding to a first blockchain and a second ledger corresponding to a second blockchain;
at least one standby processor node in communication with the at least one data storage device;
at least one standby data storage device; and
the active processor node programmed or configured to:
analyze and record blocks corresponding to data received through the network system on the first ledger and the second ledger, such that the first ledger and the second ledger have matching data;
compare and analyze two blocks from the at least one data storage device to detect at least one failure or anticipated failure of the at least one active processor node, the at least one data storage device, or any combination thereof; and
in response to detecting the at least one failure or anticipated failure, generating a switch-over command configured to cause the computing system to perform at least one of the following: switch from the active processor node to the at least one standby processor node such that the at least one standby processor node records the blocks received through the network system and is activated as a new active processor node, switch from the data storage device to the at least one standby data storage device, or any combination thereof.
