satoshiandClaude Opus 4.6 bd0b1b0318 Phase 2a: kamado-api Go middleware (core MVP)
Go 1.22 module that polls CKPool's Unix socket control API, queries
Bitcoin Core over JSON-RPC, merges both into a thread-safe snapshot, and
serves it over REST. Layout:

  ├── cmd/kamado-api/main.go              signal-aware entrypoint
  └── internal/
      ├── config/       env var loader with validation

      │                 on a ticker; readers get a copy under RWMutex
      └── httpapi/      REST handlers on Go 1.22 ServeMux:
                        /api/health /api/pool /api/users
                        /api/workers /api/clients /api/snapshot

CKPool stores hashrate as "dsps" (diff shares per second); we convert
to H/s via the 2^32 constant used by GoBrrr-Pool and other clients.
Every stat CKPool exposes to its socket API is surfaced — useragent,
IP, per-client diff, per-worker best diff — closing the gap against
Bassin which only reads the 60-second stats files.

Dockerfile does a CGO_ENABLED=0 static build on golang:1.22-bookworm
with -trimpath -ldflags=-s -w. docker-compose now runs both ckpool and
kamado-api, sharing a named volume for /run/ckpool so the API can
dial the stratifier socket directly.

Deferred to Phase 2b (called out in README):
  - Bitcoin Core ZMQ hashblock subscriber
  - WebSocket push for real-time UI updates
  - SQLite persistence (block history, best-share history)
  - CKPool log tailer for "Solved and confirmed block" detection

Tests and build NOT run in this commit — Go isn't installed in the
dev environment. Run `make api-test` or `make api` to verify.

# 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
```
┌────────────────────────────────────────────────────┐
│ ckpool-solo (C) ──Unix socket──► kamado-api (Go) │
│ ports: 3333 ports: 80 │
│ │
│ ▲ stratum ▲ HTTP/WS │

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
- [ ] Phase 2b: ZMQ block notifier, WebSocket push, SQLite persistence, log tailer
- [ ] **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 (Phase 2a):
| 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/snapshot` | Full merged snapshot (everything) |
StartOS packaging lives in a separate repository.
