Cryptocurrency emerged from the intersection of cryptography, distributed computing, and game theory. Bitcoin's 2008 whitepaper introduced a protocol where mutually distrusting nodes could agree on a shared ledger without any central authority — solving the Byzantine generals' problem with economic incentives and computational proof.
These simulations let you mine blocks by adjusting difficulty and hash rate, solve proof-of-work puzzles interactively, build and verify Merkle trees, observe consensus algorithms reaching agreement across a network, and explore how cryptographic hash functions produce avalanche effects — all with real-time animated visualizations.
