Delphi Digital unlocks Zcash report highlighting privacy advantages

Delphi Digital just made its deep-dive Zcash report available to the public. Titled “Zcash: Encrypted Money for a Surveilled World,” the report lays out a case that ZEC has been building momentum on multiple fronts: shielded-pool adoption is surging, a major protocol upgrade is on the horizon, and regulatory headwinds have calmed considerably.

The headline number is hard to ignore. The share of Zcash’s circulating supply held in shielded pools jumped from roughly 11% to nearly 30% in the span of a single year. Nearly 1 million additional ZEC migrated into shielded addresses since October 2025 alone.

Privacy adoption is accelerating

Zcash has long offered optional privacy through its shielded transactions powered by zk-SNARKs, a form of zero-knowledge cryptography that lets users prove a transaction is valid without revealing the sender, receiver, or amount. The problem was that most users never bothered to use it. Transparent transactions were easier, and the privacy pool remained small enough that using it could, paradoxically, draw attention.

The transaction volume data underscores the growing activity. ZEC recorded approximately $285 million in transaction volume over a 30-day window before the report’s February 5 publication date. For comparison, Bitcoin logged $348 million in the same timeframe.

The Tachyon upgrade and quantum resistance

Perhaps the most forward-looking element of Delphi’s analysis centers on the Tachyon upgrade, a protocol overhaul scheduled for completion by the end of 2026. Tachyon aims to improve transaction efficiency and scaling while layering in post-quantum privacy features.

The “harvest now, decrypt later” threat is real. Adversaries can store encrypted blockchain data today and attempt to crack it once quantum hardware matures. The Tachyon upgrade would incorporate cryptographic primitives designed to withstand quantum attacks, making ZEC one of the few major digital assets proactively addressing the threat.

Regulatory clarity and institutional interest

The SEC concluded its investigation into the Zcash Foundation without taking any enforcement action. That regulatory clarity appears to be catalyzing institutional moves. Grayscale is actively pursuing a spot ZEC ETF, which would give traditional investors exposure to Zcash through a familiar wrapper without needing to manage private keys or navigate crypto exchanges directly.

Delphi’s report notes high-profile stakeholders including the Winklevoss twins and VanEck as supporters of the Zcash ecosystem.

A vulnerability that was discovered and patched in Zcash’s Orchard layer reportedly caused notable market fluctuations, serving as a reminder that cutting-edge cryptography carries its own risks.
