The present disclosure presents blockchain-based cyber security management systems and related methods. One such method comprises obtaining cyber intelligence input data from a cyber defender computing device, wherein the cyber defender computing device manages network security of a network, wherein the cyber intelligence input data identifies a cyber attacker or a victim of a cyber attack on the network; executing one or more Cyber Security Management (CSM) functions with the cyber intelligence input data received from the cyber defender computing device and cyber data stored in the blockchain ledger, wherein the cyber data stored in the blockchain ledger provides details on a cyber attack on a network that is managed by another cyber defender computing device; and outputting an alert to the cyber defender computing device with a potential cyber attacker or potential victim of the cyber attack on the network managed by the cyber defender computing device.

Method and system for blockchain-based cyber security management

Described in detail herein is a system for determining the validity of a transaction in a distributed network environment. The system includes a plurality of peer servers. The system elects a set of peer leaders from the plurality of peer servers. The set of peer leaders broadcast a first set of indices associated with a first subset of transactions, received from the plurality of peer servers, to one or more of the plurality of peer servers. The set of elected peer leaders execute a first instance of a binary agreement protocol based at least in part on a second subset of indices associated with a second subset of the transactions. The set of elected peer leaders output a consensus vector comprising one or more of the transactions.
