Zcash 基金會否認與兩個第三方產品 ZRC-20 和 CASH 代幣有任何關聯，此前其 X 帳號發布的一篇文章將它們描述為 Zcash 網路的新增功能。
摘要
- Zcash 基金會表示 ZRC-20 和 CASH 與該組織沒有官方關聯。
- ZRC-20 的草案規範依賴於屏蔽備註和鏈下索引器。
- 該擬議標準不需要更改 Zcash 協議或正式的 ZIP 批准。
- 美國投資者必須區分第三方代幣與網路開發者認可的產品。
Zcash 基金會表示事先不知情
Zcash 基金會在一份聲明中表示，在該事件公開之前，它並不知道 ZRC-20 項目或相關的 CASH 代幣。據該組織稱，這兩個產品均來自獨立第三方，並非 Zcash 協議的官方組成部分。
該澄清是在基金會帳號發布的一則 X 貼文 之後作出的，該貼文宣布了一項針對 Zcash 的代幣標準。貼文稱 ZRC-20 將很快允許用戶在專注於隱私的區塊鏈上部署、鑄造和轉移代幣，並將 CASH 作為首個使用該系統的代幣。
「Zcash 現在有了代幣標準，」該貼文寫道，然後引導用戶前往該項目的網站。
然而，在隨後的回應中，基金會否認與這些產品有任何關聯，並敦促用戶在與它們互動之前自行研究。聲明指出 ZRC-20 是一個私人開發的系統，而非由該非營利組織創建、批准或運營的功能。
沒有公開解釋說明一個無關項目的宣傳材料是如何通過基金會的帳號出現的。在沒有該組織確認的情況下，該事件不能被描述為帳號被入侵或駭客攻擊。
關於運營 ZRC-20 的團隊的公開信息也仍然有限。該項目已發布技術文檔和宣傳頁面，但所審查的材料並未明確指出負責該系統的公司、法律實體或具名開發者群體。
ZRC-20 使用 Zcash 備註而不更改其協議
根據該項目的 技術文檔，ZRC-20 是一種草案同質化代幣規範，它將 JSON 指令存儲在附加於屏蔽 Zcash 輸出上的加密備註字段中。獨立索引器將按區塊順序讀取指令，並在 Zcash 共識系統之外計算代幣餘額。
文檔描述了三個操作：部署、鑄造和轉移。部署將創建一個代幣代碼並設定其最大供應量，鑄造將發行不超過該限制的單位，轉移將在索引器識別的帳戶之間移動餘額。
ZRC-20 借鑒了比特幣 BRC-20 格式的基本結構，但擬議的數據載體不同。BRC-20 通過比特幣銘文記錄代幣指令，而 ZRC-20 草案則將它們置於屏蔽 Zcash 輸出中可用的 512 字節備註字段中。
該規範指出 ZRC-20 不是共識變更，也不需要智能合約。Zcash 節點既不會驗證也不會拒絕其代幣指令，因為維護餘額帳本的是索引器，而非區塊鏈協議。
因此，Zcash 共識只會確認底層交易。對 CASH 餘額的認可將取決於遵循第三方索引和驗證規則的軟件。
該項目也不會為公開交易的代幣提供自動隱私。根據其文檔，索引器需要訪問備註才能計算餘額。一種擬議設計將操作發送到一個公共協議地址並發布其傳入查看密鑰，允許索引器解密代幣指令，即使交易的其他部分仍保持屏蔽。
所有權將依賴於嵌入每個負載中的簽名，因為 Zcash 屏蔽地址不會公開揭示誰創建了輸出。草案提出了單獨的帳戶標識符和 Ed25519 簽名，以在索引層授權鑄造和轉移。
Several features remain unresolved. The documentation lists atomic trading, payloads exceeding 512 bytes, structured memos, and possible naming conflicts among its open questions. Early exchanges would also need to be custodial because the draft does not contain an atomic trading method comparable with tools used by some Bitcoin markets.
Official Zcash changes follow a separate process
The official Zcash Improvement Proposal system provides the established route for proposing protocol features, publishing implementation details, gathering community feedback, and recording design decisions. ZRC-20 does not appear as an adopted protocol feature under that process.
A third-party application can use Zcash transactions without gaining approval from the Foundation or becoming part of the network’s consensus rules. The Foundation’s statement makes that distinction central to the dispute: ZRC-20 may attempt to build on Zcash infrastructure, but its use of the blockchain does not make it an official Zcash token standard.
The name carries another source of possible confusion. ZetaChain already uses ZRC-20 for its omnichain fungible-token format, while members of the Zcash community discussed the same label years earlier when considering how token functionality could increase activity involving ZEC.
Recent Zcash development has instead centered on formal network changes. Planned NU7 proposals have included reducing the block target from 75 seconds to 25 seconds while adjusting block rewards to retain the existing issuance schedule. Unlike the independent token system, such protocol changes require coordination among network developers, node operators and other participants.
U.S. token buyers face separate issuer questions
For U.S. users, a third party’s use of an established blockchain does not settle how regulators may treat its token offering or sale. The legal assessment can depend on how the asset is issued, marketed and sold, rather than whether the underlying network’s foundation endorsed it.
In August, the U.S. Securities and Exchange Commission proposed crypto-asset rules covering certain investment contracts involving digital assets. The proposal included possible exemptions for offerings of up to $5 million over four years and up to $75 million during a 12-month period, subject to the proposed conditions.
The SEC proposal does not classify CASH or determine its status under U.S. law. It does, however, make the identity of a token’s operator, the terms of its distribution, and the claims made to purchasers relevant details for American participants reviewing a new launch.
The Foundation’s warning also arrived while ZEC was experiencing large price swings. As crypto.news reported on Sep. 7, ZEC gained about 43% during the first week of September and traded near $1,197 after breaking above $1,000.
By Sep. 14, the privacy coin had retreated toward $1,139 after touching a multi-year high near $1,290. Futures open interest fell by about 20% over 24 hours during the pullback, while roughly $17.2 million in long positions were liquidated.
ZEC then rose more than 20% to approximately $1,337 on Sep. 16, having reached an intraday high near $1,385. The move followed renewed attention on the NU7 vote and came as traders monitored resistance around $1,375 and $1,500.
