Zcash draft ZIP merges: 50,000 ZEC to NSM, 8% stream diverts to Future Dev + Legal Defense lockbox

Bowe, Wilcox and McGee's draft would wind down ZCG, remove ~55% of its treasury via OP_RETURN and redirect the 8% dev-fund stream until the third halving. Coinholder poll: Nov 16–30.

A draft Zcash Improvement Proposal titled "Future Dev and Legal Defense Fund Lockbox, and a 50,000 ZEC donation to the NSM" was merged into the zcash/zips repository on Nov 11, 2026 as PR #1428. The draft, authored by Sean Bowe (Tachyon Foundation), Zooko Wilcox (Shielded Labs) and Jason McGee (Shielded Labs), would end Zcash Community Grants funding at activation, send 50,000 ZEC to an unspendable address, and reroute the ZCG share of block rewards into a second lockbox for development and legal defense until the third halving. CoinDesk reports that coinholder polling runs Nov 16 through Nov 30, alongside a community-panel poll.

What the draft does

  • The ZCG Committee sends 50,000 ZEC to a P2SH address whose redeem script is OP_RETURN, within 30 days of the ZIP's acceptance. The outputs cannot be spent. Wallets are directed to present payments to that address as irreversible removals.
  • A later commit on the same branch reframes the transfer as a removal from circulation credited to the Network Sustainability Mechanism (NSM), due 30 days after mainnet reaches activation height A. The NSM returns ZEC to users via future block rewards.
  • At activation, the 8% ZCG share of newly minted ZEC ends. The same 8% accrues instead to a new lockbox — the Future Dev and Legal Defense Fund — until the third halving.
  • Spending from that lockbox requires a separate ZIP. The draft cross-references PR #1423 ("Wind down Zcash Community Grants and redirect its funding") and closed PR #1414.
  • The draft was opened by a contributor using the handle aquietinvestor and approved by str4d before the merge. The filename on disk is draft-mcgee-future-dev-legal-defense-fund.md; no ZIP number has been assigned yet.

Numbers

  • 50,000 ZEC — amount sent to the OP_RETURN-script P2SH address on acceptance.
  • 91,453 ZEC — ZCG treasury balance in CoinDesk's October snapshot. The 50,000-ZEC removal is roughly 55% of that balance; approximately 41,453 ZEC would remain if the draft activates.
  • 8% — current ZCG share of each block reward. Under the draft, this share flows to the new lockbox from activation until the third halving.
  • Nov 16–30, 2026 — coinholder poll window per CoinDesk; no on-chain vote mechanism is cited in the draft itself.

How this fits the broader ZCG wind-down debate

The draft is the third serious attempt in 2026 to resize the Zcash Community Grants pipeline. ZCG's own earlier plan to move roughly 36,200 ZEC to the NSM was withdrawn after community feedback. A rival draft from Tachyon Group and Shielded Labs — sketched in the same PR chain — proposed ending ZCG funding and routing 50,000 ZEC to an unspendable address but keeping the grant program open for new proposals. Bowe, Wilcox and McGee's version diverges by preserving a future-use lockbox rather than terminating the dev stream outright, which keeps a legal-defense pool available for the project and its contributors without re-litigating the fund every halving.

The 8% dev-fund stream itself traces back to ZIP 1014, the 2020 proposal that split the first-four-year Zcash Founders Reward replacement between the Electric Coin Company, the Zcash Foundation and the Major Grants slate that became ZCG after 2024. Rediverting that same 8% — not cutting it — is the compromise this draft offers.

What to watch

  1. ZIP number assignment. The draft currently ships without one; Zcash editors typically assign one before a formal coinholder vote mechanism goes live.
  2. Coinholder polling (Nov 16–30). CoinDesk cites "polls for coinholders and community panels." The exact tooling (ZcashCommunity forum poll, on-chain nu-vote mechanism, or an off-chain Snapshot-style measure) is not stated in the merged draft.
  3. Interaction with PR #1423. The two drafts overlap: #1423 winds ZCG down and redirects its funding; #1428 removes a 50,000 ZEC slice and creates the second lockbox. Whether editors merge the two paths or tee them up as competing polls will shape what coinholders actually vote on.
  4. NSM credit mechanics. A removal-plus-NSM-credit design is subtler than "burn 50,000 ZEC": the ZEC leaves circulation now but is re-emitted over time as block rewards. The ZIP will need wallet-level handling so holders see the outputs as burned rather than pending.
