The August 2026 Bitcoin consensus events

Heights are the clock. Watch it turn.

Independent, evidence-first monitoring of the BIP-110 activation window and the expected eCash hard fork. This site pairs a plain-language explanation of what can happen with accurate live data read in the same terms.

Current tip height MOCK

958,431

Phase Voluntary signalling STARTED Before period 476: last voluntary period not yet begun. MOCK

Blocks to next milestone MOCK 1,185 to height 959,616 (period 476 begins), roughly Jul 25.

You are here MOCK

957,600 Forknet rehearsal split ~Jul 11 passed

959,616 Period 476 begins (last voluntary period) ~Jul 25 next

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

The five heights are fixed consensus heights. Dates drift with hashrate and are projections, not consensus parameters, and follow the client-source-aligned projection (the technical walkthrough's independent projection lands up to four days later for the same heights). The current tip, phase, and blocks-to-next values shown above are mock placeholders until the read model goes live.

* 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.

What is happening

Full developments ledger ›

BIP-110 is a temporary restrictive soft fork (Reduced Data Temporary Softfork, RDTS). A BIP-110-valid block is still valid to an unmodified node, but not every ordinary block is valid to a BIP-110 node. Whether that difference ever produces two chains depends on miners, not on the calendar.

Latest developments

The dated, height-stamped developments ledger goes live at launch. The newsroom pipeline publishes sourced entries (BIP-110, eCash, mining, infrastructure, meta), newest first, and the two or three most recent will preview here.
