Adds real-time block detection via ckpool log tailing and a push channel for the upcoming Svelte UI, all stdlib-only: - logmon.Tailer follows ckpool.log with rotation/truncation survival (inode + size tracking) and parses "Solved and confirmed block N" into BlockEvent values. - state.Aggregator grows a 256-entry block ring, an OnRefresh hook, and IngestBlockEvents which best-effort enriches events with the block hash via bitcoind getblockhash. - httpapi.Hub implements RFC 6455 from scratch (SHA1 handshake, unmasked text frames out, masked frames in, ping keepalive, per-client write mutex, slow-client drop) so we don't pull in a ws dependency before we can go mod tidy. - New routes: GET /api/blocks and GET /api/ws. Snapshot pushes fire on every poll tick and immediately on block-solve. ZMQ hashblock subscription and SQLite persistence are deferred to Phase 2b.5 once the s9pk packaging repo exists and we have a real build environment for adding Go deps.

# Kamado Pool
|
|
|
|
A modern, feature-complete solo Bitcoin mining pool built on a patched fork of CKPool, with a real-time web dashboard and a Go-based API middleware that surfaces everything CKPool knows.
|
|
|
|
## Why Kamado?
|
|
|
|
Existing CKPool-based solutions (like Bassin for Umbrel) read only a handful of periodic stats files and miss most of CKPool's rich data. Kamado talks directly to CKPool's Unix socket API to expose:
|
|
|
|
- Real-time per-client data: hashrate, difficulty, user agent, hardware detection
|
|
- Full block-found history with height, hash, reward, and solving worker
|
|
- Per-worker and per-client best share tracking (current + all-time)
|
|
- Network difficulty, pool efficiency, expected time to block
|
|
- Live dashboard updates via WebSocket (no 60-second file polls)
|
|
|
|
## Architecture

Three main components:
|
|
|
|
| Component | Language | Purpose |
|
|
| -------------- | -------- | -------------------------------------------------- |
|
|
| `ckpool/` | C | Stratum server, share validation, block submission |
|
|
| `api/` | Go | Socket client, REST/WebSocket API, persistence |
|
|
| `ui/` | Svelte | Real-time dashboard |
|
|
|
|
## Phases
|
|
|
|
- [x] **Phase 1** — Fork & fix CKPool, build infrastructure
|
|
- [~] **Phase 2** — Go API middleware
|
|
- [x] Phase 2a: CKPool socket client, bitcoind RPC, state aggregator, REST API
|
|
- [x] Phase 2b: CKPool log tailer, block history, stdlib WebSocket push
|
|
- [ ] Phase 2b.5: ZMQ block notifier, SQLite persistence (deferred until s9pk repo exists — need real Go build env for new deps)
|
|
- [ ] **Phase 3** — Svelte UI dashboard
|
|
- [ ] **Phase 4** — Monorepo Docker build, full stack integration
|
|
- [ ] **Phase 5** — Testing (regtest, testnet4), polish
|
|
|
|
## Quick start (dev)
|
|
|
|
```sh
|
|
cp .env.example .env # set POOL_BTCADDRESS and bitcoind creds
|
|
make up # build + start ckpool + api
|
|
curl localhost:8080/api/health
|
|
curl localhost:8080/api/pool
|
|
```
|
|
|
|
REST endpoints:
|
|
|
|
| Route | Returns |
|
|
| -------------------- | ----------------------------------------------------------- |
|
|
| `GET /api/health` | CKPool + bitcoind health |
|
|
| `GET /api/pool` | Pool stats + derived hashrate windows + chain info |
|
|
| `GET /api/users` | All users from `users` socket command |
|
|
| `GET /api/workers` | All workers from `workers` socket command |
|
|
| `GET /api/clients` | All connected stratum sessions (useragent, IP, diff) |
|
|
| `GET /api/blocks` | Recent solved blocks (in-memory ring, SQLite in Phase 2b.5) |
|
|
| `GET /api/snapshot` | Full merged snapshot (everything) |
|
|
| `GET /api/ws` | WebSocket push: full snapshot on every refresh + on solve |
|
|
|
|
StartOS packaging lives in a separate repository.
