How to Mine Block Zero (BLOZ) — rx/blockzero CPU Guide (patched XMRig)

Block Zero is a RandomX CPU chain and this pool speaks its stratum natively: the exact patched-XMRig command for rx/blockzero, the maturity and dev-fund rules that decide when your coins are actually spendable, and where the 1% fee is taken. No accounts and no sign-ups — your bz1… address is your identity on the pool.

What you need

A modern CPU — rx/blockzero is a RandomX variant: memory-hard work built for ordinary processors, not GPUs
The Block Zero XMRig build — upstream XMRig does not know the rx/blockzero algorithm, so use the project's patched release (xmrig-v6.26.0-bz4) from blockzero-ops releases
Your BLOZ wallet address — a bz1… address from the Block Zero wallet, see step 1
Nothing else: the pool has no accounts, logins or email confirmation

1. Get your BLOZ wallet

Official wallet: blockzero-core releases — the GUI wallet (bitcoin-qt) and CLI ship for Windows, macOS and Linux
Explorer (to check payments): https://explorer.bloz.org
Wallet guide: the project's step-by-step wallet doc — GUI first, CLI for servers; pick “Limit block chain storage” (prune) if you only want to mine
Block Zero addresses start with bz1… — not bc1: BLOZ and BTC are different networks and cannot be sent between each other
Take the address from Receive → Create new receiving address; a fresh wallet syncs and shows the address even before sync finishes

Use your own wallet address, not an exchange deposit address, unless the exchange explicitly says it supports pool payouts to BLOZ.

2. Install the Block Zero XMRig build

Upstream XMRig has no rx/blockzero in its algorithm list — Block Zero ships its own patched build (XMRig v6.26.0 + xmrig-bz/patch.py)
Grab xmrig-v6.26.0-bz4 for Windows or Linux from the blockzero-ops releases page — no compiling needed
The patch forces the donate level to 0 — the binary does not mine for anyone but you
Linux: enable huge pages (--huge-pages) for a solid RandomX boost; on Windows run the miner as Administrator for the same reason

HiveOS users: the same page carries hive-bzxmrig-v6.26.0 (installs as bzxmrig-6.26.0.tar.gz) — add it as a Custom miner and set the algorithm to rx/blockzero.

3. Create the mining command

Windows — save as mine-BLOZ.bat next to the miner

xmrig.exe -a rx/blockzero -o pool.ion.cool:33340 -u <YOUR_BLOZ_ADDRESS>.RIG1 -p x

Linux

./xmrig -a rx/blockzero -o pool.ion.cool:33340 -u <YOUR_BLOZ_ADDRESS>.RIG1 -p x

Replace <YOUR_BLOZ_ADDRESS> with your real bz1… address and RIG1 with your rig name
Wallet format: bz1ADDRESS or bz1ADDRESS.rigname — everything after the dot is the worker name
-a rx/blockzero is mandatory: Block Zero's variant differs from Monero's rx/0 only in the nonce position — offset 76 of the 80-byte header instead of 39 — so a build without the algorithm would hash at the wrong offset and no share would ever check out
The password field (-p x) is ignored by the pool — any value works
Several rigs: same address, different rig names (bz1ADDR.rig1, bz1ADDR.rig2, …)
Tested end to end on this pool: both project-native dialects accepted shares — the blockzero-miner.py reference miner and this patched XMRig

Miners: what was tested against this pool

Miner	Algorithm	Result on this pool
Block Zero's XMRig build CPU, Windows and Linux	`rx/blockzero`	Works — tested. A two-minute run on a Ryzen 7 CPU produced 3 accepted shares confirmed by the pool's counter, and the rig appeared in the Miners table under the test address

Stock upstream XMRig will not work, and no flag will make it work: the algorithm is simply absent from its list. The variant differs from Monero only in reading the nonce at offset 76 of the header instead of 39
The patched build pins the donate level at 0, so nothing you hash goes to anybody else

4. Pool ports

Server	Port	Protocol	Difficulty
pool.ion.cool	33340	stratum	50000

Port 33340 — plain stratum, the recommended default
The address bar of this page is always the server: pool.ion.cool

5. Autostart with systemd

The patched XMRig runs on Windows, Linux and macOS. To keep a Linux rig mining across reboots, create /etc/systemd/system/xmrig-bz.service:

[Unit]
Description=XMRig rx/blockzero (BLOZ)
After=network-online.target

[Service]
WorkingDirectory=/opt/xmrig-bz
ExecStart=/opt/xmrig-bz/xmrig -a rx/blockzero -o pool.ion.cool:33340 -u <YOUR_BLOZ_ADDRESS>.RIG1 -p x --huge-pages
Restart=always

[Install]
WantedBy=multi-user.target

Then enable it:

sudo systemctl daemon-reload && sudo systemctl enable --now xmrig-bz

HiveOS: import the hive-bzxmrig-v6.26.0 archive from the blockzero-ops releases as a Custom miner (algorithm rx/blockzero). On Windows keep mine-BLOZ.bat from step 3 in the startup folder.

6. Track your statistics

Dashboard: https://pool.ion.cool/bloz/ — paste your wallet into My Stats to see your hashrate, shares and rounds
Miners table on the dashboard shows every rig live, with per-hour hashrate and pool share
Payments tab lists every payout with its transaction ID
Public API: https://pool.ion.cool/api/pools (miningcore-compatible JSON: hashrate, connected miners, blocks, payments)

How payouts work

Scheme: PROP — your reward is proportional to your valid shares in each round
Cycle: the pool pays out every hour once your balance reaches 0.1 BLOZ
Maturity: a coinbase output unlocks after 100 confirmations (coinbase maturity 100 — about 17 hours at 10-minute blocks) — a consensus rule of Block Zero, not a pool delay
Dev & Growth Fund: from block 1500 the consensus itself requires ≥10% of every block subsidy to go to the dev fund address — the pool just builds a valid coinbase that includes it; nothing extra is taken from your balance. Watch the blocks on explorer.bloz.org
Fee: 1% — taken from the block rewards (payment.feePercent in the pool config), never from your balance
Blocks: under PROP you are paid from the blocks the pool finds; until the first block is found, balances only accumulate
Every payment is visible in the Payments tab and in the block explorer

Competitors' terms from the project's own announcements on BitcoinTalk and pool pages (October 2026). Note the fee structures differ: our 1% is a straight deduction from block rewards at payout time, while the official pool's 0% sits alongside an on-chain dev fund that every miner's blocks already carry.

FAQ

Do I need an account to mine here?

No. Point your miner at pool.ion.cool:33340 with your wallet address and the dashboard will find you by that address. There is no registration, login or email confirmation.

When will I be paid?

The pool pays out every hour once your balance reaches 0.1 BLOZ. Two clocks have to run out first: a coinbase matures after 100 confirmations (~17 hours at 10-minute blocks), and the pool's own payment interval is one hour — so the natural rhythm of the first payment is roughly a day after the pool's first block. PROP rules apply: balances only start moving once that first block is found.

Which miner should I use?

The Block Zero XMRig build (rx/blockzero) is the tested option on this pool — both project-native dialects were driven end to end against this stratum and accepted shares: the reference blockzero-miner.py and this patched XMRig. Stock upstream XMRig will not do: it has no rx/blockzero algorithm — the patch adds it — and it differs from Monero's rx/0 only in the nonce position: offset 76 of the 80-byte header instead of 39, so a stock build would hash at the wrong offset. Build options: ready-made xmrig-v6.26.0-bz4 binaries from blockzero-ops releases, or apply xmrig-bz/patch.py to the XMRig source yourself.

Can I mine from several rigs with one address?

Yes. Use the same address for every rig and give each a unique suffix after the dot: ADDRESS.rig1, ADDRESS.rig2. Each rig gets its own row in the Miners table.

Is there an encrypted (TLS) connection?

The BLOZ pool currently exposes plain stratum on port 33340 only — that is the port to use. TLS support may be added later; watch this page.

Where do I see my hashrate and payments?

On the dashboard: My Stats for your wallet, the Miners table for each rig, and the Payments tab for payout transactions. Machines can also poll the public API.
