SHA-256 mining

Doichain (DOI) mining pool

Q: What is the pool fee?

The base fee is 2.9%. The higher your hashrate and the longer you mine, the lower the fee: the grade system brings it down to 0.4%.

Q: What is merged mining?

It is mining several coins with one hashrate. The ASIC solves the primary network task, and the pool counts the same work in the merged networks, so extra coins do not reduce the income from the primary one.

Q: Which ASIC do I need for Doichain?

Any SHA-256 ASIC works, for example Antminer S21 Pro, Antminer S21 XP, Antminer S23. You can estimate the income of each one in the calculator above.

Q: How do I withdraw DOI?

Add your DOI wallet address in the dashboard: the pool sends coins once the balance reaches the minimum payout of 5 DOI.

Doichain is not mined on its own: it comes as a bonus while your ASIC works on one of the primary coins — XEC, BC2, DGB, FB, FIX, BSV, BTCS. Nothing to set up, DOI is credited automatically.

The pool has no profitability data for ROD right now — they are not in the total, although these coins are still credited.

Fee 2.9% — Newbie grade after 30 days of mining

This is income before electricity, based on the average pool profitability over the last 24 hours. Prices and network difficulty change, so the result is an estimate.

Bonus to a primary coin on SHA-256Our nodes
Primary coins:XEC, BC2, DGB, FB, FIX, BSV, BTCS
Hashrate 2.55 PH/s · Reward system: CUSTOM30M-48H

DOI is credited as a bonus to the primary coin — including when the primary coin is chosen by autoswitch.

How autoswitch works

Connect in 3 steps

Sign up on Hash-Hut and add your DOI wallet address in the dashboard.
In the pool settings of the ASIC web interface, set the pool address and the worker (click a line to copy it):
Click on the item to copy it
If your equipment is located in Russia, you can mine to this address even under whitelist-based blocking. This address should be reachable via the MegaFon provider, but you can try it with others as well.
If you are logged into your account, then here will be shown your USER_STRATUM_ID
The password can stay empty or be any character. In a couple of minutes the ASIC appears in the dashboard under “Workers”.

No separate address is needed for DOI: it is mined together with the primary coin, and the pool picks the primary coin itself.
