Zcash NU7: Proposals and Upgrade Status

Quick Answer

The retrieved ZIP 259 is a Draft deployment proposal. It describes NU7 changes, but its presence in the repository does not establish a mainnet activation or a verified community vote outcome. ZIP 259 describes a deployment that would reduce block target spacing from 75 to 25 seconds, deploy the changes in ZIP 218, ZIP 235, ZIP 237 and ZIP 2008, and disallow version 4 transactions.

Key Takeaways

This corpus does not establish mainnet activation.
The latest primary summary verifies participation (135 of 198 members; source-reported 68%) and that the poll closed.
The retrieved ZIP 259 is a Draft deployment proposal.

What the proposal actually says

ZIP 259 describes a deployment that would reduce block target spacing from 75 to 25 seconds, deploy the changes in ZIP 218, ZIP 235, ZIP 237 and ZIP 2008, and disallow version 4 transactions. Those are proposal statements, not descriptions of changes verified as active on the chain.

The abstract says version 5 and version 6 transactions would remain valid. Read the exact document version before comparing these claims with an earlier report.

Three different kinds of evidence

A document header records the editorial ZIP status. A forum discussion or vote concerns governance participation and expressed preferences.

Chain activation concerns consensus rules actually enforced at a specified network and height. None can substitute for the others.

This guide keeps the literal Draft header, an unverified activation state and separately identified February results, August questions and September participation evidence. The latest result-chart option counts remain missing; participation is not proof of approval or activation.

What the version comparison does

The NU7 tracker compares two genuinely retrieved versions of ZIP 259. Each has its own immutable URL, commit and SHA-256.

Added and removed lines show text changes, not a consensus implementation audit. The line-multiset method can miss moved lines and does not decide whether a wording change is material.

Original versions remain linked so a reviewer can inspect context.

Limits and update boundaries

The ZIP discussion link returned HTTP 403, but the primary Foundation article dated September 14, 2026 is separately available. It reports 135 ZCAP ballots from 198 eligible participants and a rounded 68% response rate for the poll that began August 27.

Results are shown in an image; retrieval of that image returned 403, so no per-option percentages, winning choice or full outcome is transcribed. February sentiment results cannot fill those missing fields.

No independently operated node establishes activation. Future changes must enter review before public publication.

FAQ

Is NU7 live?

This corpus does not establish mainnet activation. The retrieved deployment document is Draft; that is not proof of activation or non-activation.

Does the Poll show approval?

The latest primary summary verifies participation (135 of 198 members; source-reported 68%) and that the poll closed. Its option-result image was unavailable, so this draft does not verify the winning choices or infer protocol activation. February results are a different round.
