X39 Mining — Bitcoin SOLO on our own full node
1% fee, certified against a real coinbase template
X39 Mining is an independent Bitcoin SOLO pool running CKPool against our own
Bitcoin full node.
Website:
https://mining.x39matrix.orgStratum: stratum+tcp://mining.x39matrix.org:3333
HOW IT WORKS
You mine with your own Bitcoin mainnet address as the username. There is no account,
no balance and no withdrawal. If your miner finds a block, the coinbase pays you
(99%) and the operator (1%) directly in that same transaction. The pool never holds
your funds. If this pool disappeared tomorrow you would lose nothing — you would
just repoint your miner.
And to be clear about what SOLO means: other people's hashrate here does not improve
your odds. Your chance of finding a block depends only on your own hashrate. This
pool does not change your luck. It builds block templates from its own node and
handles the stratum side, nothing more.
CONNECT YOUR MINER
Algorithm: SHA-256

Password: x
Port 3333 is plain Stratum TCP, no TLS. Minimum share difficulty is currently
500,000 — low-hashrate hardware will see shares rarely; I am looking at variable
difficulty for small miners.
Then open "My miner" on the website with that same address to follow your workers,
last accepted share and accumulated accepted difficulty. Interface in English and
Spanish.
WHAT IS VERIFIED, AND WHAT IS NOT
This is the part I care about most, and I would rather tell you than have you find
it yourselves.
Verified: the 1% fee is certified against a real coinbase template from our own
node — the actual output addresses and amounts are checked, not just a line in a
config file. The certification carries an expiry timestamp, and when it lapses the
site shows "not verified" instead of assuming it is still true.
Not verified yet: the stratum path is not flagged as independently verified on the
site, and the share counters are published as raw CKPool counters with explicit
semantics (sum of accepted share difficulty) rather than as a polished reject rate.
You do not have to take my word for any of it. Read-only, no key, no account:
https://mining.x39matrix.org/api/public/stats https://mining.x39matrix.org/api/public/miner?address=YOUR_ADDRESSThe payload carries the flags counterSemantics, feeVerified and stratumVerified, so
you can see exactly where this pool stands at any moment.
I run this as an independent developer on my own infrastructure. Technical criticism
is welcome — I would rather fix something now than have it bite a miner later.
