Traditional and DATUM share one rolling window of the newest accepted work
totaling eight times network difficulty, subject to the configured minimum work.
Shares are weighted by assigned difficulty; the oldest share is clipped at the
window boundary. Finding a block does not reset the window. Each issued job freezes
its complete allocation; newly accepted shares change future jobs only.

The full subsidy plus included transaction fees is apportioned between the two
paths by their work in that window. Traditional pays a 1.5% fee on its gross share,
rounded down to satoshis. DATUM pays 0%. When DATUM work is present, 0.5% of the
Traditional gross share, rounded down, funds the DATUM Bonus from that fee. The
operator keeps the remainder. The Bonus is distributed by DATUM work; it is not a
flat 0.5% increase to each DATUM miner's reward. An all-DATUM window has no fee or
Bonus. An all-Traditional window pays the full 1.5% fee to the operator.

Traditional net rewards, DATUM gross rewards and the DATUM Bonus are each allocated
by their respective work using largest-remainder rounding. The gross path tie goes
to Traditional. Miner ties use payout script bytes in ascending order, followed by
canonical address. Work through both paths at the same address is tracked separately
for fees and Bonus, then combined into one payout output. All satoshis are conserved.

Before the minimum payout activates, every positive miner allocation is paid to that
miner's address in the block coinbase. From block 975,100, a
1,000-satoshi minimum applies per block: the pool pays the largest set of top-ranked
miners, at most 511, whose payouts all reach 1,000 satoshis. Miners with equal
weighted work are paid or left unpaid together, except that if more than 511 miners
tie for the largest allocation, only the first 511 in payout order (ascending payout
script bytes, then canonical address) are paid. Allocations of the other miners,
including work beyond the 511-recipient limit, are not paid and are shared among the
paid miners in proportion to their allocations; a DATUM Bonus forfeited by unpaid
DATUM miners goes to the paid DATUM miners by DATUM work (to all paid miners if none
of them used DATUM). In the rare case that even the top-ranked miners (those tied for
the largest allocation, at most 511) could not each reach 1,000 satoshis from the
miners' total less any forfeited DATUM Bonus that goes to paid DATUM miners, the
miners' whole total is split equally among them, and those outputs can be below 1,000
satoshis. No payout wallet holds miner rewards and there is no carried balance.
Coinbase rewards become spendable after 101 confirmations (6,481 confirmations
for blocks at height 973,440 and above); orphaned blocks provide
no spendable reward. The website's matured total is lifetime receipts, not wallet
balance. The website never sends payments.

At an empty window, a job pays its own authenticated finder after that path's fee:
98.5% for Traditional or 100% for DATUM, with no Bonus. If native block delivery
completed before its protected cohort or ordinary admission reached durable
storage, independently verified actual coinbase payments can appear while the
mining-path attribution remains unavailable. No work is invented.

Traditional uses the pool's node templates. DATUM gateways use their own synced
Bitcoin (XBT) Knots node. Both depend on the pool's shared work accounting. A separate
auditor reconstructs the issued split and checks actual on-chain coinbase outputs.

Limits: 511 miner recipients, room for an operator output, the complete coinbase
budget and the node's block limits. Before the minimum payout activates, work is
not issued if the complete split cannot fit. After activation, work is never
refused for capacity, and work beyond the top 511 miners is not paid. Use the
downloadable Kachie gateway: its setup helper creates a persistent private identity
and found-block directory; run it with run-kachie.sh.
Stock startup jobs that omit the complete split are rejected.

Use an address dedicated to this Bitcoin (XBT) chain. Legacy, nested SegWit, native
SegWit and Taproot destinations are supported. Website statistics and both path
histories are stored persistently and refresh every 30 seconds. The original solo
endpoint on port 23334 is separate.
