Mine solo. Keep the whole block. Trust nothing — verify it.
A non-custodial solo & lottery Bitcoin mining pool by SweetHash — 0% fee, 100% of the block to the finder, native Stratum V1 & V2, with the Glass Ledger cryptographic proof of custody.
Live on Bitcoin mainnet → nexuspool.io
- 0% fee, 100% to the finder. When you solve a block, the entire reward is paid to your address by the coinbase. No pool cut, no "donation."
- Non-custodial by design. You mine to your own Bitcoin address. The pool never holds, routes, or touches your coins — there is nothing to withdraw and nothing to trust.
- Native Stratum V1 and V2. Encrypted, authenticated Stratum V2 over Noise, served side by side with Stratum V1 from a single engine — not a V1 pool with a translation shim bolted on.
- The Glass Ledger. Every share's journey — counted → useful → conserved — is signed by the pool's single authority key and verifiable by anyone, offline, from the ledger alone. We don't ask you to trust us; we hand you the proof.
- Bitaxe-ready. Point any Bitaxe (Ultra / Supra / Gamma), NerdAxe / NerdQAxe, or ESP32 miner at the pool with
your-address.worker— it works out of the box with AxeOS. - Built for industrial stability. Watchdog + crash recovery, OOM caps, a durable block journal with resubmit, intelligent vardiff, and a public-profile hardening layer. A solved block is never lost to anything that isn't mining itself.
Solo mining is a lottery, and no pool can change your odds. Your probability of finding a block is set by the network — p = 1 / (D · 2³²) per hash — and it is identical on every honest pool. What NexusPool changes is everything around that hash:
We don't change your luck. We prove we didn't lose your work.
0% fee, 100% kept, your own address, and a cryptographic receipt that every hash you sent was counted, turned into useful work, and conserved if it won.
Point any Stratum V1/V2 miner at the pool. Your username is your payout address, plus an optional worker name:
Host / URL: nexuspool.io (stratum+tcp://nexuspool.io:3350)
Port: 3350
Username: <your-bitcoin-address>.<worker> e.g. bc1q…z3.bitaxe1
Password: x
- One endpoint, both protocols. Stratum V2 (Noise-encrypted) and Stratum V1 are auto-detected on the same port.
- AxeOS / Bitaxe: set the host and port above and use your Bitcoin address as the user — that's the whole setup.
- Live pool stats, your workers, and the Glass Ledger are on the dashboard at nexuspool.io.
Mining pools ask for trust: that your shares were counted, that a found block was really yours, that nothing was skimmed. NexusPool replaces that trust with signed, append-only receipts:
- Counted — your submitted hashes were recorded.
- Useful — they were turned into valid work against the current block template.
- Conserved — if you solved a block, it was preserved and submitted, not lost.
Each receipt is signed (BIP340 Schnorr) by the pool's single authority key and is verifiable offline from the ledger alone. Pin the authority key shown on the dashboard and audit the whole chain of custody yourself — no trust in the operator required.
NexusPool is a decoupled system with a hard IPC boundary, so its parts fail independently:
| Component | Stack | Role |
|---|---|---|
| Core | C11 | The mining engine — Stratum V1/V2 server, bitcoind RPC + ZMQ, GBT → coinbase / merkle / witness, unconditional block detection with exact 256-bit target math, anti-stale, hardware-aware vardiff, durable block journal + resubmit. |
| Control | TypeScript | Observability & product — persistence, per-miner stats, REST API. If it goes down, the Core keeps mining. |
| Web | Next.js | The public dashboard and Glass Ledger at nexuspool.io. |
Guiding principle: a solved block is never lost to anything that isn't mining itself.
