Blockle 0.2.9 — chain-stall fix finalized

Blockle 0.2.9 — chain-stall fix finalized (fast difficulty recovery)

Required update. It changes consensus from block height 360: older nodes/wallets will reject blocks past 360 and stop following the chain.

Why another release

0.2.7/0.2.8 added a quiet-lane difficulty decay and a miner that rebuilds its template so the decay actually applies to a solo miner. But the fast-recovery schedule was gated at height 400, and the chain stalled at 359 before reaching it — so it fell back to the slow schedule (~3.3 h grace) and took hours to recover.

The fix

• Fast decay now activates at height 360 (the first block after the stall), not 400.
• The fast schedule is aggressive: grace of one block interval (~10 min), difficulty halving every ~2 min, so a lane that outruns its hashrate recovers within an hour from any overshoot — in practice a quiet lane never freezes for more than a few minutes.
• Blocks below 360 keep validating under the schedule they were mined with.
