Promise

This dossier examines the documented purpose and mechanisms of native Zcash (ZEC) on the zcash-mainnet network. The objective is to verify how the project describes its privacy features, consensus rules, and software lifecycle through available source materials.

Established facts

The supplied original summaries describe pinned primary documentation and software versions for the Zcash ecosystem. The project identifies Zcash as originating from Bitcoin and Zerocash, utilizing zero-knowledge proofs for shielded transactions. In the supplied summary, a zero-knowledge proof can demonstrate transaction validity while concealing selected transaction details in a shielded transaction. However, the documentation explicitly warns that this does not establish anonymity for all transactions, nor does it verify deployed privacy guarantees, operator control, usage, supply, ownership, liquidity, or complete incident history. The software is described as experimental. Regarding client support, the pinned Zcash README identifies version 6.20.0 of zcashd, the historical node client, as End of Life. It reports a final End-of-Support halt on July 18, 2026, at block height 3417100. Unmodified 6.20.0 nodes stop at that specific height. The README lists Zebra and Zakura as successor node software and Zallet as wallet software. This statement concerns the legacy client only and does not establish that the Zcash network stopped or verify the deployment status of these successors. In terms of consensus mechanics, the pinned source file defines CheckProofOfWork, which compares a supplied hash with a target represented by nBits. It rejects invalid target ranges or hashes that exceed the target. This establishes that the reviewed client contains a proof-of-work validation path. Here, the reviewed proof-of-work check accepts a supplied hash only when it meets a permitted difficulty target. This code review does not independently identify all consensus rules, current deployed clients, network hashrate, miner independence, ownership, or resistance to attacks. No block or network transaction was reproduced in this review.

Unknowns

Present independent control, beneficial ownership, actual usage patterns, client adoption rates, total supply distribution, concentration metrics, liquidity depth, and the complete incident history remain unverified. No independently reviewed criterion observation was admitted in this documentary lot for identity, usage, token-role, supply, concentration, value-capture, control, security, governance, accountability, incidents, continuity, or execution. The review is limited to the supplied documentary mechanisms.

Consequences

The README reports an end-of-support stop for unmodified legacy zcashd 6.20.0 nodes at the specified height. Its list of successor software supplies no verification of their present deployment. The scope of the warning is client software; it supplies no proof that the Zcash network stopped. Current client adoption and the privacy behavior of deployed transactions require separate observations. This review remains limited to the pinned documentation and proof-of-work check.

Verdict

Operational strength remains unproven. The asset is unrated with 0% scoring coverage. The absence of independent verification for essential criteria such as identity, supply, and control means no definitive conclusion can be drawn regarding the project's resilience or fairness. The documentation provides technical definitions but lacks empirical evidence of real-world application or security auditing.

What would change it

Reproduced identity checks, independent dated network observations, and criterion-specific evidence would be required to update this assessment. Calibration and editorial review following the submission of verifiable data on usage, supply, control, and security incidents would allow for a potential score assignment. Until such evidence is provided, the status remains unrated based solely on documentary claims.

zcash/zcash: pinned client README

The pinned Zcash README identifies version 6.20.0 of zcashd, the historical node client, as End of Life. It reports a final End-of-Support halt on July 18, 2026 at block height 3417100: unmodified 6.20.0 nodes stop at that height. The README lists Zebra and Zakura as successor node software and Zallet as wallet software. This statement concerns the legacy client and does not establish that the Zcash network stopped or verify deployment of successors. The project describes Zcash as originating from Bitcoin and Zerocash and using zero-knowledge proofs for shielded transactions, where a proof can demonstrate validity while concealing selected transaction details. This documentation does not establish anonymity of all transactions, deployed privacy guarantees, operator control, usage, supply, ownership, liquidity or complete incident history. It warns that the software is experimental.

zcash/zcash: pinned proof-of-work checks

The pinned source file defines CheckProofOfWork, comparing a supplied hash with a target represented by nBits and rejecting invalid target ranges or hashes that exceed the target. This establishes that the reviewed client contains a proof-of-work validation path. It does not independently identify all consensus rules, current deployed clients, network hashrate, miner independence, ownership or resistance to attacks.
