The block pays you, not the pool.
Every block B2Pool finds carries one output per miner. Your address is written into the block itself, by the transaction that creates the coins. They are yours the moment the block is mined — no pool wallet ever holds them, and there is nothing to withdraw.

What almost every other pool does.
The pool's address collects the whole block reward. Your share becomes a number in the operator's database, and some time later a second transaction sends it on. Between the block and your wallet sits a balance you have to trust somebody to honour — and a payout run that can be delayed, batched, or simply stop.
What happens here instead.
We build the coinbase ourselves, per block, from the live TIDES split. When one of our miners solves a block, the transaction that mints the reward already lists every miner who earned a slice, with the amount next to their address. The pool never takes custody, because the coins never pass through us. This is the same mechanism DATUM uses — we run it on the ordinary stratum ports too, which very few pools do.
Maturity is the chain's rule, not ours.
Freshly mined coins cannot be spent right away. That holds for every coinbase on the network, at every pool, and it is consensus — not a policy we could waive. Normally the wait is 100 blocks. While the long coinbase maturity soft fork is active, from block 973,440, every coinbase mined in that window unlocks at block 979,920. The difference a coinbase payout makes is not the wait; it is that the coins are already yours while you wait, sitting at your address on the chain, not on the pool's books.
Below the threshold.
An output worth less than 10,000 sat is not written into the block — a dust-sized output costs more to spend than it carries. Anything under that is carried forward and paid with your next slice. Your miner page shows both what has been paid and what is still carried.
Questions worth asking first.
Do I have to withdraw anything?
No. There is no withdrawal, no minimum balance to reach before you can request one and no button to press. Your address is in the block; the payout happened when the block was found.
When can I spend what I mined?
When the coinbase matures — 100 blocks normally, and for coins mined during the long coinbase maturity soft fork, at block 979,920. This is a rule of the chain and applies to every miner and every pool on the network equally.
Is the ticker BTCB2 or XBT?
Both refer to the same coin. Exchanges and explorers list the BLAKE2b fork of Bitcoin (BIP-110) as BTCB2, and a growing number now list it as XBT. It is the coin this pool mines and pays out in either case; check which symbol your exchange uses before you send a withdrawal to it.
What happens if the payout feed is unreachable?
The block still gets built. If the pool's payout split cannot be fetched when a template is made, the coinbase pays the pool address and that single block is settled from the wallet afterwards, exactly as a conventional pool would. A missing answer costs nobody a block.
