Cycle Lab · Protocol clock

The halving changes issuance—not destiny.

Canonical blocks anchor the protocol timeline while demand, miner economics, fees and liquidity remain separate variables.

Research state4 verified events · point-in-time snapshot

Verified record

Four events. Exact hashes.

The local snapshot resolves each subsidy epoch through its canonical height, block hash and UTC timestamp.

What the chart shows

The current subsidy epoch, estimated blocks remaining, one-month hashrate history and the next difficulty adjustment.

Blue Rogues Read

Issuance is deterministic; the estimated calendar date is not. Faster or slower blocks move the countdown.

What it confirms

The protocol supply schedule and canonical halving blocks.

What it does not confirm

Demand, miner profitability, fee-market strength or a post-halving price response.

Evidence required next

Watch block-time drift, difficulty, hashrate and demand evidence as separate families.
