the node itself reports 21.72 M for the next block without easing; the base above is computed independently and should match it.

Estimates: the hashrate stays where it is and blocks arrive at their expected pace; ASERT alone, the easing can make single blocks faster; 1-minute means within 10 % of 60 s.

WHAT ASERT DOES

Every block has a schedule: block n is due 60 s × n after genesis. ASERT compares the last block's time with that schedule. For every 2 hours the chain is behind, the difficulty halves; for every 2 hours ahead, it doubles. It started at 100.00 M, which needs about 7.2 PH/s for 60-second blocks, and it looks only at the schedule, so one slow or fast block cannot swing it.

WHAT THE EASING DOES

If no block has been found 20 minutes after the last one, the block being mined may use a lower difficulty: half after 22 minutes, a quarter after 24, and so on, halving every 2 minutes by its own timestamp. It applies to that one block only; the next block starts again from the ASERT base. A block must also come at least 30 seconds after the one before it.

WHY BLOCKS ARE SLOW RIGHT NOW

The miners now bring about 427.31 TH/s. At the current base of 21.72 M a block would take about 3 m 38 s on average, so most blocks come in through the easing, 20-30 minutes after the one before. Each slow block puts the chain further behind its schedule, and every 2 hours behind halves the base, so block times shorten step by step until the difficulty meets the hashrate.

The rules are consensus code: ASERT in src/pow.cpp, the launch rules (R1, R2) in the chain parameters. This page recomputes them from the block headers; /api/difficulty has the numbers as JSON.
