What is a share in Monero mining?

A share in Monero mining is proof that your device has done some mining work for a pool. It usually does not create a Monero block or earn a reward on its own. Instead, the pool uses your accepted shares to measure your contribution and work out your part of its mining rewards.

A share is a small proof of work

When you mine Monero, your device runs RandomX, Monero’s mining algorithm—the rules your computer follows to search for a valid result. It repeatedly produces a hash, a digital result calculated from the mining data.

A result must meet a very strict target to qualify as a new block on the Monero network. Finding one is difficult, especially with just one device.

A mining pool gives you an easier target called share difficulty. When your device finds a result that meets that target, it submits it to the pool as a share.

That share is not a piece of a coin. It is evidence of work. The pool checks it before counting it toward your contribution.

How a share differs from a block

Your device is doing the same basic work whether it finds a share or a block. The difference is how demanding a target the result meets.

• An ordinary share meets the pool’s target but not the network’s stricter target. It helps the pool track your work.
• A block-winning share also meets the network’s target. The pool can submit that block to the Monero network.

If the network accepts the block, it earns the block reward and any included transaction fees. As of 2026, Monero’s ongoing base reward is 0.6 XMR per block.

Most shares never become blocks. They still matter because they let a pool divide rewards without relying only on who happened to find the winning result.

Why share counts can be misleading

Not every share represents the same amount of work. A higher-difficulty share takes more attempts to find on average than a lower-difficulty share.

For example, one share at difficulty 10,000 represents the same expected work as ten shares at difficulty 1,000. So a miner submitting fewer shares may still be contributing more computing power.

Many pools use variable difficulty, often shortened to vardiff. This automatically changes your share target to keep submissions arriving at a manageable pace.

If your share count drops after the pool raises difficulty, your mining speed has not necessarily fallen. Look at difficulty-weighted accepted work or the pool’s longer-term speed estimate, rather than share count alone.

What your share status means

Your mining screen may show several statuses:

• Accepted: The pool checked your share and counted it.
• Stale: Your share arrived after the pool had moved on to newer work. Whether it receives credit depends on the pool.
• Rejected or invalid: The pool did not count it, perhaps because it missed the target, repeated an earlier submission, or contained an error.

An accepted share does not promise an immediate payment. Your earnings depend on the pool’s reward method, fees, and payout rules. In browser mining, also check whether the displayed “shares” are actual pool-accepted Monero work or just the website’s internal credits.

The bottom line

A share is your pool’s receipt for mining work, not a coin or a guaranteed payment. Focus on accepted work, share difficulty, and the pool’s payout rules—not just a rising share counter.
