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. + +## Design Decisions + +### Why real Bitcoin mining instead of arbitrary proof-of-work? + +The 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. + +### Why Stratum v2 upstream + Stratum v1 local? + +- **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 +- **SV1 local (to downstream miners)**: JSON-RPC is trivial to implement, no handshake overhead, works over local WiFi with negligible latency +- BitAxe already has both implementations — we reuse them + +### Why Braiins Pool as default SV2 pool? + +- Native SV2 support with published authority pubkey +- 0% PPLNS fee option +- Lightning Network payouts (useful for converting mining revenue to e-cash) +- The authority pubkey is known: `024e031a0b63c7885b19e48f76d49ddbcda9bf3d7f1d6b05df8b71569e2c2f7ff0` + +### Why dual payout mode (Lightning sats vs e-cash)? + +A TollGate's position in the mesh determines what it earns: + +| Position | Hashrate goes to | Earns | +|----------|-----------------|-------| +| Standalone (has direct internet) | Braiins pool | Lightning sats for operator | +| Mesh node (upstream TollGate detected) | Upstream TollGate's proxy | e-cash / megabytes / minutes | +| Relay (no ASIC, no internet) | Nothing locally | Just proxies for downstream miners | + +The `mining_payout_mode` config field controls this: `auto` (default) detects upstream TollGate and chooses accordingly. + +### Why mine with CPU too? + +UX. 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. + +### Why sandbox mint access? + +Miners 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. + +### Why hashprice from block template? + +The conversion from hashrate → bandwidth needs a price signal: + +``` +hashprice = (block_subsidy * blocks_per_day) / (difficulty * 2^32) [sat/GH/day] +allotment = (hashrate_ghs * hashprice_per_s * duration_s) / price_per_step * step_size +``` + +Calculating 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. + +### Why BitAxe as git submodule? + +The BitAxe ESP-Miner firmware (GPL-3.0) runs on the same ESP-IDF v5.x on ESP32-S3.
