What is the Monero block time target and why does it matter for solo mining?

Monero targets one new block about every two minutes across the whole network, not one block every two minutes for each miner. If you mine solo, this matters because your share of the network’s mining power determines how often you can expect to find one—and the wait can be much longer than you think.

Two minutes is an average, not a schedule

A block is a group of transactions added to Monero’s shared transaction record, called the blockchain. Miners use computing power to compete for the chance to add the next block and collect its reward.

The two-minute target does not mean a block arrives exactly every 120 seconds. One might appear in seconds; another might take several minutes.

Monero adjusts difficulty, the measure of how hard it is to find a valid block, after every block. This helps keep the long-term average near two minutes as miners join or leave. It does not remove the randomness of individual block discoveries.

At that target, the whole network produces roughly 720 blocks per day.

Your mining share determines your expected wait

Your hashrate is the number of mining calculations your device performs each second. For solo mining, what matters is your hashrate compared with the total network hashrate.

A useful estimate is:

Expected time to find a block ≈ 2 minutes ÷ your share of network hashrate

For example, suppose you provide 0.001% of the network’s mining power. That is one hundred-thousandth of the total.

• Your expected rate would be about one block per 100,000 network blocks.
• At two minutes per block, that means about 200,000 minutes.
• That works out to roughly 139 days per block on average.

This is a hypothetical example, not an earnings forecast. Your device speed and network difficulty can change. Use your measured mining speed and a live calculator or blockchain explorer to estimate your own situation.

An average wait is not a payout deadline

Solo mining has variance, meaning your actual results can differ greatly from the average.

Even if your estimated average wait is 139 days, you might find a block tomorrow—or find nothing for far longer. Assuming your mining share stays constant, you have only about a 63% chance of finding at least one block during one expected waiting period.

Mining without success does not make your next attempt more likely to win. You do not build up progress toward a guaranteed block.

That is the key solo-mining trade-off: you receive the block reward when you succeed, but you must be comfortable with long stretches of no income. Monero’s base reward is currently 0.6 XMR per block, plus the transaction fees included in that block.

Your node and the reward waiting period

A node is software that checks blocks and keeps track of the blockchain. For solo mining, a synchronized, well-connected node helps your miner work on the latest block. Running a node does not increase your share of mining power.

After you find an accepted block, newly mined coins remain locked for 60 blocks. At the target pace, that is about two hours—not an exact clock-based wait.

The bottom line

The two-minute target tells you how often the network finds blocks, not how often you will get paid. For solo mining, calculate your expected wait from your network share, then plan for the real wait to be much longer.
