No hidden fees, no silent changes. Pool fees are hardcoded into block coinbase templates and auditable on-chain.
| 30-Day Unique Miners | Pool Fee | Status |
|---|---|---|
| 0 – 24 Unique Miners | 0.25% (25 bps) | CURRENT ACTIVE TIER |
| 25 – 99 Unique Miners | 0.50% (50 bps) | Upcoming |

• Anti-Gaming Rule: Tiers count unique payout wallet addresses, never worker names or connection counts.
• 14-Day Advance Notice: Any fee adjustment requires sustaining the threshold for 30 consecutive days and a mandatory 14-day advance notice.

Why Work-Weighted PPLNS-8D Matters for ASICs
▼
Traditional pools count raw share rows equally. This penalizes high-difficulty ASICs: submitting 1 share at diff 131,072 represents the same expected work as 128 shares at diff 1,024.
Our pool calculates reward shares strictly proportional to total expected hashes performed across the last 8 network difficulties of accepted work.
Coinbase rewards are split directly inside the block transaction (up to 512 outputs). Balances under the 546-sat dust limit roll up into the persistent owed ledger for subsequent block payouts.

Frequently Asked Questions
▼
Do I need custom firmware for BM-S3?
No. Standard factory stock firmware is 100% supported. The gateway automatically adapts the BTCB2 work header to what the ASIC expects.
When do mining rewards mature?
Per Bitcoin consensus rules, coinbase transactions require 100 block confirmations before funds become spendable on-chain.
What is the minimum payout threshold?
Minimum payout per block is 546 satoshis (standard Bitcoin dust limit). Sub-546 balances roll into the owed ledger for the next pool block.
Is this pool protected against block withholding?
Yes. Built on the DATUM protocol with anti-block-withholding assignment slots to protect all honest miners.
