Monero (XMR) Solo Mining Pool: How It Works and What to Check
Choosing a Monero mining pool requires more than comparing fees and hashrate. XMR uses RandomX, a proof-of-work algorithm optimised for general-purpose CPUs and designed to reduce the advantage of specialised hardware. That lets you take part in mining without depending on dedicated ASICs, but it does not remove a fundamental question: how your work is handled, and what happens to the reward once a block is found.
Monero supports several different models. A shared pool groups the hashrate of many participants and distributes rewards according to a set payout system. P2Pool does something similar in a decentralised way. It is also possible to mine solo, running the necessary infrastructure yourself and taking on all the variance individually.
There is also an operational middle ground: using a pool's infrastructure to do solo mining. The pool provides Stratum connectivity and the infrastructure needed to process work and submit blocks, but rewards are not shared among its participants.
That is the model OwnBlock uses.
What exactly is a Monero mining pool?
In a shared pool, many miners contribute hashrate to the same infrastructure. By combining computing power, the pool finds blocks more often than each participant would alone, and later distributes rewards according to the agreed payout system.
Two common models are PPLNS and PPS. Under PPLNS, the reward depends on the shares submitted within a given window when the pool finds a block. Under PPS, the miner receives a set amount for every valid share, and the operator absorbs the variance between what is paid out to participants and the blocks it actually finds.
Solo mining works differently. You individually keep your own probability of finding a block. That probability depends on your hashrate relative to the difficulty and the network's total hashrate. With little computing power, long periods can pass without finding one; when one is found, though, the reward is yours, since you produced the valid work.
OwnBlock uses this second model. There is no PPLNS, PPS, or reward-sharing among the pool's users. You compete independently and only receive a reward when your own work finds a valid block.
The difference from running the entire infrastructure yourself is purely operational: OwnBlock provides the Stratum service and the infrastructure needed to connect to the mining network, while you keep the variance that is characteristic of solo mining.
How to choose a good Monero mining pool?
There is no single pool that is best for every case. The right choice depends on the mining model you want, your tolerance for variance, where your hashrate is located, and how the service handles rewards. There are several criteria worth checking before connecting any computing power:
Where OwnBlock fits into this
OwnBlock is a solo mining pool for XMR. Its role is not to pool the rewards of different miners and split them proportionally. Each participant mines independently and keeps their own probability of finding a block.
OwnBlock provides the infrastructure that sits between the mining software and the Monero network: Stratum servers, receiving and validating work, worker management, block construction, and submission once a valid solution is found.
The XMR service currently includes solo mining with no PPLNS or PPS, dedicated infrastructure in Europe, a 2% fee, direct distribution via a coinbase split, no custodial balance held within the pool, access with no KYC, compatibility with XMRig, compatibility with NiceHash and MiningRigRentals, and a public dashboard showing hashrate, miners, and blocks found.
This model does not reduce the variance of solo mining, and it is important to understand that before starting. Accepted shares let you measure the work submitted and confirm your miner is running correctly, but they do not by themselves create a payable balance. You only receive a reward when you find a valid block.
If what you are looking for is to spread out the variance and receive rewards proportional to your contributed hashrate, P2Pool is a different alternative and is worth evaluating as such.
You can check the pool's hashrate, the network's hashrate, and the history of blocks found directly from OwnBlock's public dashboard.
Transparency and on-chain verification
One of the differences in the model OwnBlock uses is that your reward originates directly in the block's coinbase transaction.
Coinbase transactions — also called miner transactions in Monero — follow different rules from ordinary transfers. Among other quirks, they use a Null RingCT type, so their outputs do not hide amounts via RingCT the way a conventional transaction does.
This makes it possible to publicly verify the structure and amounts of the reward created by a block.
Monero's privacy, however, remains relevant: observing an output on-chain does not by itself reveal which Monero address received it. Outputs use cryptographically derived keys, and the recipient's address is not published directly on the blockchain.
OwnBlock uses that property to offer verifiability without automatically turning your full address into public information.
When a block is found, the pool generates and keeps the tx_key used in building the coinbase. Combining that tx_key, the transaction, and your address makes it possible to cryptographically prove that a given output was intended for that address.
The pool publishes these proofs for the blocks it finds, and they can be cross-checked using P2Pool Observer, an independent tool from the Monero community.
OwnBlock also publishes the information needed to verify the output corresponding to its own fee. This makes it possible to independently confirm that the block attributed to the pool exists, and that the coinbase distribution matches the declared scheme.
There is an important distinction here: anyone can audit the public information of the block and the pool, but publicly proving that your output belongs to a specific address requires knowing that address together with the corresponding cryptographic proof. It is up to you whether to reveal that link.
This mechanism also makes it possible to technically demonstrate that the funds received originated as a mining reward, and not as a later transfer from an operator wallet.
If an exchange, custodian, or institution requests documentation on the origin of funds, this proof can provide cryptographic evidence of their provenance. Whether it is accepted as sufficient documentation will, naturally, depend on each entity's own compliance policies.
