SweetHash builds NexusPool.
Verification over trust, which is easy to put on a page and harder to ship. Below is what SweetHash is building, the two proofs that are finished, and the things we do not claim.
One company, three tracks.
They are at very different stages. The status on each card is the honest one rather than the flattering one.
NexusPool
LiveA solo and lottery mining pool with a from-scratch C core, its own full node, and both Stratum V1 and native encrypted Stratum V2 served from one engine. Non-custodial, 0% fee, the whole block paid on-chain to the address you supply. It mines Bitcoin, Bitcoin Cash, and Litecoin with Dogecoin merged in.
Home mining hardware
In fabricationA line of mining hardware for one person or a small fleet, not for a warehouse. It is in the fabrication process now, and it is not available to buy. We are not publishing a name, a specification, or a date for it here, because none of those are things you could check yet.
Firmware and AI research
In developmentFirmware for cryptocurrency mining hardware, and separate research work in artificial intelligence. Both are earlier than the pool. They get their own announcements when there is something to point at.
Two things you can check without us.
Every mining pool asks you to take one thing on faith: that it received your work, counted it correctly, and would pay you honestly. These two exist so you do not have to.
Glass Ledger
Every rig that mines here gets a receipt for the work the pool counted from it: how many shares, at what difficulty, over which window. Each receipt carries a BIP340 signature you check offline, against a key we publish and you pin yourself. Checking one needs no API call to us and no trust in a dashboard.
How proof of custody works →Payout Preflight
Enter your address and the pool rebuilds the exact coinbase transaction it would pay you, byte for byte, using the same construction a real block uses. You confirm where the money lands before you have won anything, instead of finding out you had a typo on the one day it matters.
Run a preflight →The gaps, in our own words, first.
A pool whose whole argument is that you should verify things does not get to be vague about its own limits. These are the ones worth knowing before you point a rig anywhere.
There is no third-party security audit.
What exists is internal review, fuzzing, and differential testing against real nodes. That is real work, but it is not an audit and we will not call it one. Because the pool is non-custodial and never holds funds, the worst case for a defect is a lost share or a lost block, not lost coins.
The core is MIT licensed. The source is not public yet.
The public repository ships a README, the license, and a version file today. The license is real; the code it applies to is not there yet. Verifying the pool does not depend on it either way, since a receipt is checked against a published key rather than against the code that wrote it.
Most rigs get a counted receipt, not a reconciled one.
A counted receipt covers what the pool saw: shares, difficulty, window. A reconciled receipt also cross-checks your firmware’s own hashrate, and most stock firmware has no way to report that. The difference is stamped on the receipt rather than averaged away.
We do not improve your odds. Nobody can.
A block costs D · 2³² hashes on average, where D is the network’s difficulty, and that is identical at every pool including this one. Solo mining is a lottery, an average is not a schedule, and most miners never find a block.
None of this is on our word.
Asked before pointing a rig here.
NexusPool is built by SweetHash. SweetHash develops firmware for cryptocurrency mining hardware, is in fabrication on a line of home mining hardware for individual and small-fleet miners, and conducts research in artificial intelligence. NexusPool is one product in that portfolio, and the one that is finished.
SweetHash builds non-custodial mining infrastructure. Its shipped product is NexusPool, a solo and lottery mining pool for Bitcoin, Bitcoin Cash, and Litecoin with Dogecoin merged in. SweetHash also develops mining firmware, has home mining hardware in fabrication, and conducts research in artificial intelligence.
NexusPool has not been audited by a third-party security firm. Its verification is internal: code review, fuzzing, and differential testing against real nodes. Because the pool is non-custodial and never holds funds, the worst outcome of a software defect is a lost share or a lost block, not lost coins.
The NexusPool core is MIT licensed, but its source has not been published yet. The public repository currently contains the README, the license, and a version file. Verifying the pool does not depend on source access: a Glass Ledger receipt is checked offline against a published key, whoever wrote the code.
SweetHash develops firmware for cryptocurrency mining hardware and conducts research in artificial intelligence. It also has a line of home mining hardware in fabrication, aimed at individual and small-fleet miners rather than industrial deployment. No product names, specifications, or dates have been published for that hardware yet.
NexusPool signs each work receipt with a BIP340 Schnorr signature covering the shares it counted, the difficulty it served, and the window. The miner verifies that signature offline against a public authority key NexusPool publishes itself, which requires no API call to NexusPool and no trust in its dashboard.
The mark, if you're writing about us.
Vector and raster, full color and the monochrome version, all on the page below. No form, no account, no request to approve.
The wordmark is set in Cerotu, a display face used for the logo and nowhere else on the site. It is reproduced in the files above; we do not distribute the typeface itself.
- Keep the icon as shipped: no recoloring, no gradient, no stretching or skewing.
- Give it clear space; do not crowd it against other logos or set it inside dense text.
- Use the white lockup on anything that is not a dark, near-black surface.
- Don't reset the wordmark in another typeface. If Cerotu will not render, "NexusPool" in plain text is correct.
Point a rig at it and check for yourself.
The connection details are on the landing page, and the receipts start the moment your first share lands.
