1# Mining-for-Bandwidth Implementation Plan
2
3## Overview
4
5Add Bitcoin mining (Stratum v1 + v2) to the TollGate firmware so that devices earn internet access by mining real Bitcoin blocks. A BitAxe (ESP32-S3 + BM1366 ASIC) running TollGate firmware becomes a plug-and-play mesh node — no e-cash, Nostr identity, or prior setup required.
6
7## Design Decisions
8
9### Why real Bitcoin mining instead of arbitrary proof-of-work?
10
11The work must be **useful** — mining against a Stratum v2 block template means every share contributes to Bitcoin's security. Even at negligible hashrate (ESP32 software mining at ~10-50 kH/s), the work is real. With a BM1366 ASIC (~500 GH/s), the device produces meaningful hashrate.
12
13### Why Stratum v2 upstream + Stratum v1 local?
14
15- **SV2 upstream (to pool)**: Binary framing is bandwidth-efficient, Noise encryption prevents hash hijacking, and the encrypted tunnel uses minimal megabytes on the paid internet link
16- **SV1 local (to downstream miners)**: JSON-RPC is trivial to implement, no handshake overhead, works over local WiFi with negligible latency
17- BitAxe already has both implementations — we reuse them
18
19### Why Braiins Pool as default SV2 pool?
20
21- Native SV2 support with published authority pubkey
22- 0% PPLNS fee option
23- Lightning Network payouts (useful for converting mining revenue to e-cash)
24- The authority pubkey is known: `024e031a0b63c7885b19e48f76d49ddbcda9bf3d7f1d6b05df8b71569e2c2f7ff0`
25
26### Why dual payout mode (Lightning sats vs e-cash)?
27
28A TollGate's position in the mesh determines what it earns:
29
30| Position | Hashrate goes to | Earns |
31|----------|-----------------|-------|
32| Standalone (has direct internet) | Braiins pool | Lightning sats for operator |
33| Mesh node (upstream TollGate detected) | Upstream TollGate's proxy | e-cash / megabytes / minutes |
34| Relay (no ASIC, no internet) | Nothing locally | Just proxies for downstream miners |
35
36The `mining_payout_mode` config field controls this: `auto` (default) detects upstream TollGate and chooses accordingly.
37
38### Why mine with CPU too?
39
40UX. We don't care if CPU mining is profitable. A plain ESP32-S3 without an ASIC can still produce non-zero hashrate (~10-50 kH/s via hardware SHA256 accelerator). This means ANY ESP32 running TollGate firmware can bootstrap itself — even one byte per hour is better than zero.
41
42### Why sandbox mint access?
43
44Miners who earn bandwidth via hashrate should also reach the Cashu mint URLs the TollGate accepts. This way they can receive e-cash from mobile wallets without first having internet access. The firewall whitelists mint URLs for unauthenticated clients.
45
46### Why hashprice from block template?
47
48The conversion from hashrate → bandwidth needs a price signal:
49
50```
51hashprice = (block_subsidy * blocks_per_day) / (difficulty * 2^32) [sat/GH/day]
52allotment = (hashrate_ghs * hashprice_per_s * duration_s) / price_per_step * step_size
53```
54
55Calculating hashprice from the `nbits` field in the SV2 block template is automatic, requires no external API, and is always accurate. A config override (`hashprice_sats_per_ghs_day`) is available as fallback. A ContextVM MCP tool (`get_hashprice`) is planned for future dynamic pricing.
56
57### Why BitAxe as git submodule?
58
59The BitAxe ESP-Miner firmware (GPL-3.0) runs on the same ESP-IDF v5.x on ESP32-S3. It contains production-quality implementations of:
60- `components/stratum_v2/` — SV2 protocol + Noise handshake
61- `components/stratum/` — SV1 protocol
62- `components/asic/` — BM1366/BM1368 serial drivers
63
64Rather than copying code that will diverge, we reference it as a submodule and compile selected components.
65
66## Architecture
67
68```
69[Bitcoin SV2 Pool (Braiins)]
70 ↑ SV2 + Noise (encrypted, binary)
71[TollGate Gateway] (ESP32-S3, has internet via STA)
72 ├── stratum_client.c — SV2 upstream to Braiins (Noise handshake, job reception, share forwarding)

91## Config Fields (config.json)
92
93```json
94{
95 "mining_enabled": true,
96 "mining_payout_mode": "auto",
97 "stratum_host": "v2.pool.braiins.com",
98 "stratum_port": 3333,
99 "stratum_user": "bc1q...TollGate",
100 "stratum_pass": "x",
101 "stratum_sv2_authority_pubkey": "024e031a0b63c7885b19e48f76d49ddbcda9bf3d7f1d6b05df8b71569e2c2f7ff0",

104 "mining_port": 3333,
105 "hashprice_sats_per_ghs_day": 0,
106 "mining_sandbox_mint_access": true
107}
108```
109
110| Field | Default | Description |
111|-------|---------|-------------|
112| `mining_enabled` | `false` | Enable mining subsystem |
113| `mining_payout_mode` | `"auto"` | `"auto"`, `"pool"`, `"upstream"`, `"proxy_only"` |
114| `stratum_host` | `"v2.pool.braiins.com"` | SV2 pool hostname |
115| `stratum_port` | `3333` | SV2 pool port |
116| `stratum_user` | `""` | Bitcoin/Lightning address for pool payout |
117| `stratum_pass` | `"x"` | Pool password |
118| `stratum_sv2_authority_pubkey` | Braiins key | Pool authority pubkey for Noise verification |
119| `stratum_fallback_host` | `"public-pool.io"` | SV1 fallback pool hostname |
120| `stratum_fallback_port` | `21496` | SV1 fallback pool port |
121| `mining_port` | `3333` | Local mining proxy listen port |
122| `hashprice_sats_per_ghs_day` | `0` | Manual hashprice override (0 = auto from nbits) |
123| `mining_sandbox_mint_access` | `true` | Allow unauthenticated clients to reach mint URLs |
124
125## Mining Payout Modes
126
127### `auto` (default)
128```
129TollGate boots → connects to WiFi (STA)
130 → tollgate_client_detect(gw_ip)
131 → GET http://gw_ip:2121/
132 → If upstream TollGate detected → mine to upstream proxy → earn e-cash/bytes
133 → If regular router → mine to Braiins pool → earn Lightning sats
134```
135
136### `pool`
137Always mine to Braiins/public-pool via SV2. Never mine to upstream TollGate. Gateway's own hashrate earns Lightning sats for the operator.
138
139### `upstream`
140Always mine to upstream TollGate's proxy. Fail if no upstream TollGate detected. Gateway's own hashrate earns e-cash/bytes/minutes.
141
142### `proxy_only`
143Don't mine locally at all. Only run the local proxy for downstream miners. Useful for plain ESP32 relay nodes without ASICs that don't want to waste CPU on mining.
144
145## Sandbox / Firewall Changes
146
147Unauthenticated clients (no Cashu, no session) get access to:
148- `TCP :3333` — mining proxy (get jobs, submit shares)
149- `TCP :2121` — tollgate API (`GET /mining/job`, `POST /mining/share`)
150- `TCP :80` — captive portal
151- `TCP/443` to `mint_url` — so miners can receive e-cash from mobile wallets
152
153## Hashrate-to-Bandwidth Conversion
154
155```
156difficulty = nbits_to_difficulty(job.nbits)
157hashprice_sats_per_ghs_day = (312500000 * 144) / (difficulty * 2^32)
158hashprice_sats_per_ghs_s = hashprice_sats_per_ghs_day / 86400
159
160allotment_ms = (client_hashrate_ghs * hashprice_sats_per_ghs_s * measurement_window_s)
161 / price_per_step * step_size_ms
162```
163
164The measurement window is a sliding interval (e.g., 30 seconds). Shares submitted during the window are counted, hashrate is estimated, and allotment is calculated and granted via `session_create()` or `session_extend()`.
165

4Implement Bitcoin mining-for-bandwidth in a proper git worktree so the shared `esp32-tollgate` repo stays clean for other LLM sessions.
5
6## Worktree Location
7- **Shared repo:** `/home/c03rad0r/esp32-tollgate` (stays on `master`, always clean)
8- **Mining worktree:** `/home/c03rad0r/esp32-tollgate-mining` (on `feature/mining-payment` branch)
9
10## Checklist
11
12### Phase 1: Cleanup & Setup
13- [x] 1.1 Backup all mining files to `/home/c03rad0r/mining-work-backup/`
14- [x] 1.2 Restore shared repo to clean master (discard edits, remove untracked, delete accidental branches)
15- [x] 1.3 Create `feature/mining-payment` branch from master
16- [x] 1.4 Create git worktree at `/home/c03rad0r/esp32-tollgate-mining`
17- [x] 1.5 Copy backup files into worktree
18- [x] 1.6 Verify worktree is clean and on correct branch
19
20### Phase 2: Apply Tracked File Edits (in worktree)
21- [x] 2.1 Edit `main/CMakeLists.txt` — add 6 mining source files + `tcp_transport`
22- [x] 2.2 Edit `main/config.h` — add `mining_payout_mode_t` enum + mining fields
23- [x] 2.3 Edit `main/config.c` — add mining defaults + JSON parsing
24- [x] 2.4 Edit `main/tollgate_main.c` — mining includes, init, tick
25- [x] 2.5 Edit `main/tollgate_api.c` — 3 mining endpoints + discovery tag
26- [x] 2.6 Edit `main/session.h` — `payment_method_t` enum + field
27- [x] 2.7 Edit `main/session.c` — set payment_method in create functions
28- [x] 2.8 Edit `main/firewall.h` — `firewall_set_mining_port()` + `firewall_set_sandbox_mint_access()`
29- [x] 2.9 Edit `main/firewall.c` — sandbox allowlist + includes
30- [x] 2.10 Edit `main/tollgate_client.h` — `TG_CLIENT_MINING` state + mining discovery fields
31- [x] 2.11 Edit `main/tollgate_client.c` — mining tag parsing in discovery
32- [x] 2.12 Edit `main/captive_portal.c` — tabbed UI with Cashu/Mine tabs
33- [x] 2.13 N/A — esp-miner not in worktree (not needed as component)
34
35### Phase 3: Build & Test (in worktree)
36- [x] 3.1 Clean build from scratch (`rm -rf build && idf.py build`)
37 - Note: Pre-existing nucula_lib build error (`save_proofs()` is private) blocks full link
38 - All mining-specific source files passed compilation
39 - nucula_lib error exists in both main repo and worktree (not caused by mining changes)
40- [x] 3.2 Run existing unit tests (`make test-unit`)
41- [x] 3.3 All tests pass (84/84: 61 existing + 23 new mining_payment)
42
43### Phase 4: Missing Unit Tests
44- [ ] 4.1 `test_stratum_proxy.c` — job management, stats
45- [ ] 4.2 `test_session_payment_method.c` — payment_method field
46- [ ] 4.3 `test_tollgate_client_mining.c` — mining discovery tag parsing
47- [ ] 4.4 `test_firewall_sandbox.c` — sandbox allowlist logic
48- [ ] 4.5 All new tests pass
49
50### Phase 5: Commit
51- [x] 5.1 Stage all changes in worktree (2 commits made)
52- [x] 5.2 Commit with descriptive messages
53- [ ] 5.3 Push branch to origin (Nostr git relay issue — branch exists locally)
54
55### Phase 6: Merge (when ready)
56- [ ] 6.1 Squash-merge `feature/mining-payment` into `master`
57- [ ] 6.2 Remove worktree
58- [ ] 6.3 Push master
59
60## Commits Made
611. `c75230e` — feat(mining): add new mining source files and unit tests
622. `beb73a2` — feat(mining): integrate mining subsystem into existing modules
63
64## Known Issues (pre-existing)
65- `nucula_lib/nucula_wallet.cpp` calls private `save_proofs()` — build error in both repos
66- Nostr git relay (`relay.ngit.dev`) rejected push — branch exists locally only
67
68## Rules
69- **NEVER** edit files in `/home/c03rad0r/esp32-tollgate/` directly
70- **ALL** work happens in `/home/c03rad0r/esp32-tollgate-mining/`
71- **Commit frequently** — don't lose work again
72- No comments in code unless explicitly requested
