MiniBTC: the build log

A Bitcoin-style blockchain built from scratch in Rust — consensus, UTXO set, P2P, mining, an HD wallet, JSON-RPC, CLI, explorer and an MCP server that can inspect the chain and draft payments but never spend without a human. Built in the open on a private devnet.

JSON-RPC server + typed client + the full command surface.

P10 · explorer

Read-only HTML explorer: blocks, transactions, addresses, mempool.

P11 · mcp server

11 tools, resources, prompts — spending gated on human approval.

P12 · attack lab and hardening

All 15 blueprint attacks, fuzzing, property tests, million-op load runs.

ship
Attack lab + ship gate

Every blueprint phase landed: 15 attack scenarios automated and passing, four fuzz targets at ~26M executions with zero crashes, nine property invariants, a 6M-operation load run, and a three-node devnet that survives a deliberate fork — resolved by most-work, with a two-wallet payment confirmed through the live network.

P13 · UI expansion

Enriched read-only explorer + a local web wallet with in-memory sessions, CSRF and a human-gated send flow.

ui
Explorer + wallet UI

Restructured after UX review (Solana-explorer-style flows): create/restore/unlock landing, two-step wallet creation with a show-once seed gate, dashboard hero + action bar, receive/addresses/activity pages — plus the earlier enriched explorer. Beyond the blueprint's read-only explorer: global search, pagination and dashboard stats on the public side, and a separate key-holding wallet UI with passphrase-to-memory sessions, per-session CSRF, origin checks, a two-step build-review-confirm-broadcast send flow, and a secret-free audit log — live-verified end to end on the devnet.

P13b · wallet entropy hardening

Coldcard-class weak-RNG attack test: low-entropy seeds collide; real generator verified full-width.
