Hello Bitcointalk,
First things first:
Grand Pool is not a new pool. It has been running in production since
the beginning of 2025, mining real blocks and paying real miners every day. We simply never had a
thread on this forum, and since Bitcointalk is still the place where miners actually talk to pool
operators, it felt wrong to keep ignoring it. So here we are.
If you would rather not take our word for it, our hashrate and found blocks are tracked
independently on MiningPoolStats:
https://miningpoolstats.stream/grandpool.io_pools
Supported CoinsBoth ASIC coins and GPU coins are supported side by side. The list is extended regularly, see the
roadmap section below.
Every coin has its own page with the full connection details: regional endpoints, ports, and both
plain
stratum+tcp and encrypted
stratum+ssl options. There is no registration and no
email, your wallet address is your username, so you can be hashing about a minute after opening
the page.
Why Grand PoolZero fee while we grow. We are currently running a 0% fee across every coin and every mode
to bring new miners to the pool — the more hashrate we have, the shorter the rounds are for
everyone. This is a growth decision, not a permanent promise: if fees are introduced later, it
will be announced in this thread in advance, never silently.
Three reward modes. Steady income with PPLNS, round-based payouts with PROP, or the full
block reward with SOLO. Pick per coin, switch whenever you want.
VarDiff on every port. The pool automatically adjusts share difficulty to the hashrate of
your device. A single Bitaxe and a full container farm can point at the same endpoint, no manual
port juggling, no "which difficulty do I pick" guesswork, no wasted shares on either end.
Automatic payouts every 4-8 hours. No withdrawal requests, no manual approvals, no waiting
for the operator to wake up. Balances above the minimum threshold are sent out automatically on
each payout cycle.
Multiple regions. Endpoints in Europe, North America and Asia, so you connect to a server
that is actually close to you instead of eating 200ms of latency and the stale shares that come
with it.
Built in Go, built for uptime. The pool core is written in Go and runs as a distributed
master/slave setup over a message bus: regional stratum servers are independent of each other, so
a problem in one region does not take the rest of the pool down. Share validation and block
template propagation stay fast under load, which means fewer stale shares on chains with short
block times, and adding a new coin or a new regional endpoint is a matter of minutes.
Telegram BotWe have a Telegram bot that turns your phone into a full mining dashboard:
- Live worker status and hashrate per device
- Offline / hashrate-drop alerts, so you find out about a dead rig in seconds instead of the next morning
- Payout notifications with tx links
- Pool-wide stats: found blocks, network difficulty, connected hashrate

Roadmap — Proof of Useful WorkWe keep adding coins, but lately our main interest has shifted toward
Proof of Useful Workchains, where the hashrate is not burned on an arbitrary puzzle but spent on real computation —
AI model training and inference in particular.
This is the reason Pearl is already live on the pool: it required writing a custom stratum
implementation from scratch, which is exactly the kind of work most pools will not take on. We are
currently evaluating several more PoUW / AI-inference chains for integration.
If you are working on a PoUW chain and need a pool that will actually implement your protocol
instead of asking you to fit into a generic template, get in touch.
Links & ContactsFeature requests, coin suggestions, bug reports and criticism are all welcome in this thread. We read and answer everything here.
Happy mining.
