Dogmcoin Pool Share Shift
how it’s computed →
Each day’s share is that pool’s blocks divided by all DOGM blocks found that UTC day, the pool read from the Litecoin coinbase inside each AuxPoW header. Only complete days are drawn — today never is.
The six pools with the largest trailing share are drawn; everything else is counted as other. The headline score is z = (s − s̄) / √(s̄(1−s̄)/N) against the trailing seven full days: |z| ≥ 4 is an event, pools under 2% of trailing share are not scored, and days with fewer than 50 blocks are skipped.
s_p(d) = blocks found by pool p on UTC day d / all blocks that day; baseline = the pool's share over the trailing 7 full days; z = (s_p(d) - baseline) / sqrt(baseline*(1-baseline)/N_d) (binomial, N_d = blocks that day); event = |z| >= 4; pools below 2% trailing share are not scored
What a pool share shift is
Pool share shift is the one-day change in a mining pool’s share of Dogmcoin blocks, measured against that pool’s own trailing week and scored in standard deviations of block luck. On Dogmcoin the pool behind a block is read from the Litecoin coinbase embedded in its AuxPoW header — DOGM is merge-mined under Litecoin parent pools, so a shift here is a shift in whose parent work carried DOGM that day, not a decision any DOGM-side miner made. In our dated attribution study (2026-10-02 → 2026-10-10), okminer 17.5%, yiimp 14.5% and ViaBTC 6.5% of DOGM blocks carried those tags. DOGM’s rotating chain ID forces pools onto createauxblock — part of why Mining-Dutch is the only payer we verified.
How much is luck on Dogmcoin
Dogmcoin targets a block every 60 seconds — about 1,440 a day — so a pool holding 17.5% of the chain — okminer, in our dated attribution study (2026-10-02 → 2026-10-10) — expects to wobble about ±1.0 percentage points on an ordinary day from luck alone. The event line is drawn at four of those standard deviations, from that arithmetic and nothing else; a day that reads 2σ is weather, not news. Retarget cadence is irrelevant here (Dogmcoin retargets every block (DigiShield, Dogecoin-1.14 class)): difficulty decides how many blocks a day there are, not who finds them.
FAQ
- Is a 2σ move on Dogmcoin an event?
- No. With about 1,440 DOGM blocks a day, a pool holding 17.5% of the chain wobbles about ±1.0 percentage points from luck alone. The line is drawn at 4σ so that pure luck produces fewer than one false event per pool per century of days.
- Does this say who mines Dogmcoin?
- It names who found the Litecoin parent block. Dogmcoin is merge-mined under Litecoin parent pools, and some parent pools do not pay DOGM to their miners — the note at the top of this page says so. A shift here is a shift in whose parent work carried DOGM that day.
- Why share of blocks and not hashrate per pool?
- Pool hashrate is not on-chain; block counts are. A pool’s share of the day’s blocks times the network hashrate is an estimate with its own luck error bar, so we score the share itself — the quantity our Dogmcoin node can actually count.
