bitcoin-forks.org August 2026 consensus-event monitor

Timeline

The event clock and the timeline of record

Two layers. First the event clock: the five fixed consensus heights of the BIP-110 window and the phases between them. Below it the developments ledger: dated, height-stamped, sourced entries, newest first. Heights are the clock; the dates are projections that drift with hashrate.

Preview build. The five heights and their milestones are fixed facts. The event clock below now reads the live chain-height feed; the developments ledger further down is still pending and populates at launch.

Event clock

Current tip height
current tip height: live at launch
Phase deployment phase: live at launch Derived from chain height on the node's selected branch, never set by hand.
Blocks to next milestone blocks to next milestone: live at launch Recomputed from the current tip against the next fixed height.
957,600 Forknet rehearsal split ~Jul 11
959,616 Period 476 begins (last voluntary period) ~Jul 25
961,632 Mandatory signalling begins ~Aug 7
963,648 Lock-in deadline; expected eCash fork* ~Aug 21
965,664 Maximum activation (RDTS active on enforcing nodes) ~Sep 1

feed timestamp: live at launch

The passed, next, and "you are here" markers on the rail reflect the live tip when the feed is reachable; otherwise they stay unmarked and the pending chips above remain. Because deployment state is branch-relative, a deep reorganization can move the computed position backward on the affected branch: that is treated as correct behaviour, not a bug. The activation explainer covers the state machine and why the schedule can shift earlier if a voluntary period reaches the threshold. The dates above follow the client-source-aligned projection; the technical walkthrough's independent projection lands up to four days later for the same heights.

* The eCash-fork alignment at 963,648 is an expectation from the 2026-07 eCash announcement, not a settled fact, and could still shift. See the eCash stub for the reconfirmable source.

Developments

last updated: at launch

The developments ledger is the timeline of record: dated, height-stamped, sourced entries produced by the campaign newsroom, newest first. Each entry carries a category pill, a short plain-language summary, and source links. Corrections appear as new entries linking the superseded one; published entries never change. Categories: BIP-110 eCash mining infra meta

Ledger pending

No entries yet. The newsroom pipeline begins publishing at launch, on a cadence of a few hours rather than a live feed. The full ledger will also be published as a CC0 flat file via the data downloads, like every other dataset on this site.
