Fleet Pool: Guide for Hosted Miners

Your datacenter runs your machines on Fleet Pool: a pool where every block it finds is divided among all clients by the work each one did recently. Your part is created directly at your Bitcoin address, inside the block’s own transaction. We take a fixed 1% of each block; the clients share the other 99%.

On your own, your machines would wait for a whole block, which can take years. In Fleet Pool you receive a part of almost every block the pool finds. It is still Bitcoin mining: the pool can find two blocks in a week and then none for months, and nobody receives anything between blocks.

You need a Bitcoin address from a wallet you control. There is nothing to sign: your machines use your address as username, and that address is paid.

Version 1.0 · 1 November 2026 · Bitcoin (BTC). Your datacenter has a written agreement with us for Fleet Pool. The operator guide is Fleet Pool: Setup Guide for Datacenters. Numbers on this page use the network difficulty of 1 November 2026 (148.36 T).

Key takeaways

• Every block of the pool is divided by the work in the window: the most recent shares of all clients, weighted by difficulty, at most 90 days old.
• Your part is an output of the coinbase at your address. It can be spent after 100 confirmations.
• A part below 5,000 sat becomes a credit and is paid in a following block. A debit is an extra you already received, taken from your next parts.
• Your page shows your share of the window, hashrate, balance, total paid, an estimate for the next block and every payout.
• If you stop mining you keep receiving a shrinking part while your work is still in the window.

Fleet Pool in one minute

All clients of your datacenter mine on the same pool. When the pool finds a block, the reward (3.125 BTC today, plus the transaction fees of the block) is divided like this:

• 1% to us, as its own output of the coinbase.
• 99% to the clients, each in proportion to their work in the window.

Example: your machines did 2% of the work in the window. Your part is 2% × 3.125 BTC × 99% = 0.061875 BTC, plus 2% of the transaction fees after our 1%, at your address in that block.

The window

Every share your machines send enters the window with its difficulty. The window holds the most recent work of the pool, up to the work needed on average to find one block. When new work arrives the oldest leaves, and no share stays longer than 90 days.

With 100 PH/s in the pool, the window holds about the last 73.8 days of work. This has two effects you should know:

• When you start, your share is small and grows day by day while your work fills the window. A block found in your first week pays you only a small part.
• When you stop, your share shrinks slowly, and blocks found in the following weeks still pay you a part.

Nothing restarts when a block is found: the window keeps sliding, and every block is divided by the same rule.

Credits and debits

A coinbase output below 5,000 sat is not created. If your part of a block is smaller, it is not lost and does not go to the pool:

• It becomes a credit in your balance. At the next block the credit is added to your new part, and you are paid when the total reaches 5,000 sat, even if you no longer mine.
• The value of your part was spread over the clients paid in that block. Each of them gets a debit of the same amount, taken from their next parts.

So a credit means “the pool owes you this, paid with a following block”; a debit means “you already received this, it will be taken from your next parts”. Credits and debits of all clients sum to about zero.

Example: a Bitaxe at 1.2 TH/s in a 100 PH/s pool has about 0.0012% of the window. Its part of one block is about 3,700 sat: it becomes a credit. At the next block credit and new part make about 7,400 sat, and the Bitaxe is paid in that coinbase.

Your machine settings

Your datacenter configures the machines. If you check them yourself, they look like this:

The address before the dot is the one that is paid. Check that it is yours, written exactly. Fleet Pool accepts connections only from your datacenter’s network.

Your page

Open solofury.com/fleet-pool/?addr=<your address>, or the link your datacenter sent you. It updates every minute and shows:

• Share of the window: your part of the recent work, the part the next block pays you.
• Hashrate and workers online: your machines as the pool sees them.
• Balance: credit, debit or nothing pending.
• Paid in total: everything paid to your address in coinbases.
• If the pool finds a block now: an estimate with your current share, 3.125 BTC and the 1% fee; transaction fees are added on top.
• Fleet Pool now: how many miners are in the window and its size.
• Your payouts: each block with date, amount, share and type (“in the coinbase” or “to balance”).

Your page shows only the data of your address. Anyone who has the link can see it, like any miner page of the site; the list of all clients is not public.

Verify a payout yourself

1. In “Your payouts”, note the block height of a payout.
2. Open that block on any block explorer and find its first transaction, the coinbase.
3. Among its outputs you find your address with the amount on your page, and our 1% at bc1q68egs68a3arhc8fj92pu920h062sqk9rvyd2ey.

The amount can differ from “share × reward” by your balance: a credit paid in that block adds to it, a debit reduces it.

If you stop mining or change datacenter

There is nothing to sign or cancel. Your work stays in the window until newer work pushes it out, or for at most 90 days, and each block found until then pays you a shrinking part. A credit below 5,000 sat is paid by a following block if it reaches the threshold; after 90 days without shares it is offset against open debits of other clients.

What is coming

• Telegram alerts for a block found, your payouts and machines offline.
• Public Fleet Pool terms next to the Fleet terms. Today your datacenter has a written agreement with us; ask them for the rules that apply to you.

What the numbers say

A pool of 100 PH/s finds about 4.95 blocks a year on average. With 2 PH/s in that pool you receive about 0.0619 BTC per block, about 0.31 BTC a year on average, before transaction fees. These are averages, not income: blocks come at random, and a gap of several months is normal. Mining alone with 2 PH/s gives the same expected value, but as one block every several years, or none.

How we work

• Non-custodial payout. Your part is an output of the coinbase; the network creates the bitcoin at your address.
• Nothing kept by the pool. Parts too small for the coinbase become credits and are paid later; they never go to our fee.
• Every payout on the blockchain. Your page shows the block of each payout, so you can check it yourself.

Conclusion

In Fleet Pool your machines take part in almost every block the pool finds. Each block pays you by your recent work, directly at your address, with a 1% fee. Small parts wait as credit and are paid later. Your page shows your share, your balance and every payout, and each payout can be checked on the blockchain.
