Why ask for this?

It stays on this device. We only send it if this browser finds a block that could win, so we know where to contact or pay you. A payout can happen only if Bitcoin accepts the block and the project wallet receives the reward.

What are your hashes?

This is the number of Bitcoin hash attempts your browser has made on this device. It grows while mining is running and is stored locally so you can see your progress.

What is hash rate?

Hash rate is how many Bitcoin hash attempts your browser is trying per second right now. A higher number means your device is checking more possibilities.

Terms of Use

oneblock.work is a browser-based Bitcoin mining project. Mining starts only when you choose to start it, and you can stop at any time. Nothing is installed on your device and there is no software download.

If your browser finds a valid Bitcoin block, the block is accepted by the Bitcoin network, and the project receives the reward, you may receive the BTC amount shown for your selected power level. Mining is based on chance, so a payout is never guaranteed.

By starting mining, you allow this page to use CPU and, when available, GPU resources while the page remains open. Closing the page or pressing Stop ends the mining session.

Mining can increase device load, heat, fan noise, battery use, and power consumption. Please use a power level that feels comfortable for your device and stop mining if you notice unusual heat, instability, slowdown, or any other concern. You are responsible for deciding whether this service is appropriate for your equipment.

Privacy Policy

If you enter an email or BTC address, it is stored in your browser and shared only when this browser finds a block that could win.

The service may process session identifiers, candidate metadata, and operational metrics to run the service, reduce abuse, and verify candidates.

Your selected language, payout contact, lifetime hash count, and performance hints may be stored locally on your device.
