Practicals

Every practical states why it exists, what it will teach you when it fails, and the safety rules that protect your keys. Never enter a private key or seed phrase anywhere in BCM.

BCM-P01

Break a chain, then reason about it

aimUse the BCM chain, mempool, PoW and double-spend simulators to show why a distributed network needs an ordering rule, and record what you observed.

why it existsLearners who only read about hash linkage conclude that hashing makes history unchangeable. Editing a historical block and then re-mining it disproves that in about two minutes.

BCM-P02

Your first public blockchain transaction

aimCreate a wallet, obtain Sepolia test ETH, send a transaction, find it in a block and read it on an explorer.

why it existsThis is the OGM live lab. It converts abstract vocabulary — wallet, RPC, node, validator, gas, block, explorer — into one traceable event the learner produced themselves.

toolsMetaMask, Ethereum Sepolia testnet, A Sepolia faucet, Sepolia block explorer
