SupaPool works with any Equihash ASIC, such as an Antminer Z15 or Z15 Pro. In your miner’s pool settings enter one of the URLs below, your Zcash address as the username, and x as the password (or d= and a number to choose your difficulty, see below).

Use TLS if your miner supports it: it hides your traffic from your network provider. Both endpoints give the same work.

Your username is the Zcash address that should receive the reward. Transparent addresses (t1… and t3…) work, and so does a unified address (u1… or tu1…) that includes a transparent receiver: the reward is paid to that receiver. Shielded-only addresses (zs1…, zu1…, or a u1… without a transparent part) and exchange TEX addresses (tex1…) don’t, because a block’s reward can only pay a transparent address. Zcash also requires mined coins to be shielded before they can be spent, so use a wallet that does this for you, such as Zashi or YWallet, not an exchange deposit address. An invalid address is refused when the miner connects.

To tell several machines apart, add a dot and a name after the address. Each name shows up as its own worker on My Stats. All workers of one address pay to that address.

In the Antminer’s web interface open Miner Configuration and enter stratum+tcp://zec.stratum.supapool.xyz:3403 as the pool URL, your Zcash address as the worker (add .name to tell machines apart) and x as the password. The pool lowers the difficulty to suit a small miner by itself.

If your firmware has a TLS option, use port 3404 instead.

Every hash has the same chance of finding a Zcash block, so a home miner can win the whole reward. On average, at today’s network difficulty:

Network difficulty 95.7 M. These are averages: luck decides, and a block can come years early or late. Miners here have found 0 so far.

The pool sets each miner’s share difficulty automatically (vardiff) so it submits a share every few seconds, starting at 256. Difficulty never goes below 16.

To choose your own starting and minimum difficulty, put d= and a number in the password field. Vardiff can still raise it if your miner is faster.

Share difficulty only changes how often your miner reports in. It doesn’t change your chance of finding a block.

Rental services work with the pool. They send very large amounts of hashrate, so they are given a higher minimum difficulty automatically:

• nicehash: minimum difficulty 1.02 K

On NiceHash choose the Equihash algorithm and enter the TCP URL above as a custom pool.

On MiningRigRentals add the pool with the TCP URL, your address as the worker name and x as the password. If the rig disconnects for low share rate, set a difficulty with d= in the password.

In solo mining you don’t share rewards with anyone. Each hash your miner computes has a tiny chance of solving a block. If one does, the whole block reward (minus the pool fee) is yours. If none does, you earn nothing. There are no partial payouts.

The reward is paid in the block itself: the pool builds each block so that its first transaction pays your address directly. The pool never holds your coins, and there is nothing to withdraw. The coins become spendable after 100 confirmations (about 42 min).

The pool fee is 1% of the block reward. It is taken only when you find a block.

Effort compares the work done since the last block with what a block takes on average. 100% means average luck; it can go far above 100% without anything being wrong. It resets when a block is found.

Best share is the highest difficulty any of your shares has reached. A share that reaches the network difficulty is a block.

Share quality shows how close a share came to a block, on a logarithmic scale: log10(share difficulty) ÷ log10(network difficulty). 100% or more is a block. It shows how lucky a share was, not progress saved up towards a block.

A rejected share didn’t count, usually because it arrived after a new block made its work out of date (stale), was a duplicate, or didn’t meet the difficulty. A few percent is normal; a high rate usually means a slow network connection.

A block’s reward can be spent once the block has 100 confirmations: 100 blocks mined on top of it. At about 25 s per block that takes around 42 min. The Blocks page shows how many each block has so far.

Do I need an account?

No. Your address is your identity. Open My Stats, enter the address, and bookmark the page.

How often will I find a block?

It depends only on your hashrate compared with the whole network’s. Divide the network hashrate by yours and multiply by 25 s for the average wait. For a single ASIC that can be years; it can also happen today.

My miner shows as idle. What should I check?

A worker is active if it sent a share in the last ten minutes. Check the miner is powered and online, the pool URL and port are right, and the username is a valid Zcash address.

What happens if my block is orphaned?

Occasionally two miners find a block at almost the same time and the network keeps only one. An orphaned block pays nothing. This is part of how Zcash works and is rare.

Check Pool status at the top of every page first. If the pool shows Online and your miner still can’t connect, the problem is usually the URL, port or address on the miner.
