Blockchain Network Simulator

Blockchain networks stay secure not through a central authority but through decentralized gossip and majority consensus. This simulator visualizes a peer-to-peer mesh of nodes: when one peer mines a block, it spreads hop by hop across the network's direct connections until every node holds the same chain. Trigger a simulated malicious fork to see why a minority broadcast — however fast — can never out-race the honestly gossiped majority chain. Adjust peer count, network latency and block rate to see how topology and timing shape how quickly the whole network reaches consensus.
