NexusPool

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.

Why NexusPool

• 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. Spec-conformant on both standard and extended V2 channels.
• 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, on V1 or native V2.
• See your payout before you win. Payout Preflight rebuilds the exact coinbase that would pay you — byte-for-byte, the same construction used for every real block — so you can verify the destination before a block is ever found.
• Built for industrial stability. Watchdog + crash recovery, OOM caps, a durable block journal with resubmit, hardware-aware per-rig vardiff, and a public-profile hardening layer. A solved block is never lost to anything that isn't mining itself.

The honest part

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.

Connect a miner

Point any Stratum V1/V2 miner at the pool. Your username is your payout address, plus an optional worker name. One endpoint serves both protocols on the same port — V2 (Noise-encrypted) and V1 are auto-detected.

Stratum V1 / AxeOS:

Host / URL:  nexuspool.io          (stratum+tcp://nexuspool.io:3350)
Port:        3350
Username:    <your-bitcoin-address>.<worker>      e.g.  bc1q…z3.bitaxe1
Password:    x

Native Stratum V2 (Noise-encrypted, authenticated). Use the full connection string — it carries the pool's authority key so your client can pin the pool's identity:

stratum2+tcp://nexuspool.io:3350/9amd6GUzTaGXASESCa75c9Rx3vWYihRyLUAE3Vrmqwgm3T9jtxN

• One endpoint, both protocols. V2 and V1 share port 3350 and are auto-detected; standard and extended V2 channels are supported.
• Pin the authority key. The key embedded in the V2 string is the pool's single signing identity — the same one shown on the dashboard and used for the Glass Ledger. Pin it and every job and receipt is verifiably ours.
• 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.

Verify, don't trust

NexusPool is built so you can check it rather than believe it. Everything below is public and non-custodial:

• Glass Ledger — signed, offline-verifiable proof that your work was counted → useful → conserved.
• Payout Preflight — enter your address and see the exact coinbase that would pay you, before you win.
• Pool statistics — live pool hashrate, blocks, and top-miner leaderboards. A Donate option is in the footer for anyone who wants to support the project.
• Status — forward-only availability history for each component of the pool.
• Changelog — every release, in plain language.
• Terms of Use — NexusPool stated plainly: free, non-custodial software — a communication protocol, not a product, service, or investment; SweetHash never holds your funds or keys; and solo mining is a lottery with no guarantee of finding a block.
• Your fleet is yours. Public stats and leaderboards mask addresses — other miners cannot enumerate your workers or your hashrate.

The Glass Ledger — proof of custody

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.

Architecture

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 per-rig vardiff, durable block journal + resubmit.
Control	TypeScript	Observability & product — persistence, per-miner stats, rig telemetry, REST API. If it goes down, the Core keeps mining.
Web	Next.js	The public dashboard, Glass Ledger, and tools at nexuspool.io.

Guiding principle: a solved block is never lost to anything that isn't mining itself. The public deployment adds a hardening layer — watchdog + auto-restart, ingress protection, and rate limiting — on top of that guarantee.

Adoption

NexusPool is listed among the production pools on the official Stratum V2 site, stratumprotocol.org — its native V1 & V2 support is interoperable with spec-compliant Stratum V2 clients.

Status

Live on Bitcoin mainnet at nexuspool.io, currently v0.7.26.13 — pre-1.0 (v0.6.x), in active hardening. This repository is being opened up progressively — starting with this README.
