Demos
Launch the blockchain visuals
Browser-only, no backend. Hashes, blocks, mining, consensus, signatures, Merkle proofs, addresses, and more. Dark by default; built to teach.
Quick start
- ➜ Hashing Lab for SHA-256 + avalanche
- ➜ Blockchain Demo for blocks & tampering
- ➜ Mining Visualizer for difficulty intuition
- ➜ Consensus Simulator for rounds & BFT
All demos
See the poems ↗Hashing Lab
SHA-256 live hashing, avalanche effect grid, and a mini proof-of-work.
Hashing
Blockchain Demo
Wallets → transactions → blocks → chain immutability and tampering.
Immutability
Mining Visualizer
Nonce search vs target difficulty rendered in real time.
Proof-of-Work
Merkle Tree Explorer
Build a tree, inspect proof paths, and watch the root change.
Data
Keys & Signatures
Generate a keypair, sign, and verify with WebCrypto ECDSA.
Crypto
Consensus Simulator
Step through rounds with honest & Byzantine nodes.
Fault tolerance
Byzantine Generals
Interactive take on why n ≥ 3f + 1 matters.
BFT
Forks & Reorgs
Competing branches, orphaned blocks, and reorg intuition.
Networks
Addresses & Checksums
From public key to address to Base58Check checksum.
Integrity
