Zcash and privacy protocols face a “do-or-die” SEC meeting that determines if developers are personally liable for code
The SEC’s Crypto Task Force scheduled a four-hour roundtable on monetary surveillance and privacy for Dec. 15, bringing collectively zero-knowledge proof developers, civil liberties advocates, and protocol executives to debate whether or not blockchain privacy instruments can coexist with anti-money laundering enforcement.
The timing is deliberate. Two months in the past, the co-founders of Samourai Wallet acquired five- and four-year prison sentences for working what prosecutors known as an unlicensed cash transmitter that facilitated $237 million in unlawful transactions.
Three months earlier than that, a jury convicted Tornado Cash developer Roman Storm on unlicensed money-transmitting expenses however deadlocked on money-laundering conspiracy and acquitted him on sanctions violations.
FinCEN’s proposed Section 311 rule focusing on worldwide cryptocurrency mixing as a “class of transactions of main cash laundering concern” stays unfinished, with its remark interval closed since January 2024 and its last textual content anticipated in 2025.
Commissioner Hester Peirce, who leads the duty drive, framed the event as a likelihood to “recalibrate monetary surveillance measures to make sure the safety of our nation and the liberties that make America distinctive.”
The panel listing reads like a blueprint for what that recalibration may appear to be: Zcash founder Zooko Wilcox, Aleo CEO Koh, Espresso Systems CSO Jill Gunter, and SpruceID founder Wayne Chang characterize the zero-knowledge and privacy-preserving computation camp.
Summer Mersinger from the Blockchain Association and J.W. Verret from George Mason Law School deliver the coverage and authorized framing.
ACLU senior coverage analyst Jay Stanley represents the civil liberties perspective that has traditionally handled monetary surveillance as a Fourth Amendment stress level.
The three-level squeeze on privacy instruments defines the backdrop. Samourai’s sentences present the harshest operational-liability end result for wallet-linked mixing: co-founders Keonne Rodriguez and William Lonergan Hill pleaded responsible, and Judge Denise Cote sentenced them in November 2025.
The DOJ handled Samourai as a mixer that enabled darknet markets, cyber intrusions, and transactions tied to sanctioned jurisdictions.
The idea is: if a software program facilitates monetary privacy and somebody operates it as a service, they run an unlicensed money-transmitting enterprise.
The Storm verdict attracts a narrower line. The jury convicted him on the unlicensed transmitter conspiracy however deadlocked on the extra severe money-laundering cost and acquitted him on sanctions-related conspiracy.
Prosecutors argued that Tornado Cash enabled over $1 billion in unlawful transactions, together with flows tied to North Korea-linked actors. Still, the jury confirmed larger consolation with punishing “cash transmission” theories than with affirming the complete “developer equals launderer” leap.
FinCEN’s Section 311 proposal is the regulatory overhang that makes the SEC roundtable really feel coordinated with a broader federal posture.
The company issued the discover of proposed rulemaking in October 2023, figuring out worldwide cryptocurrency mixing as a money-laundering concern and proposing enhanced recordkeeping and reporting necessities for lined monetary establishments once they know, suspect, or have purpose to suspect a transaction entails such mixing.
Legal analyses on the time famous how uncommon it was for FinCEN to make use of Section 311 to focus on an exercise class fairly than a particular establishment or jurisdiction.
The remark interval resulted in January 2024. A Unified Agenda entry indicated motion towards a last rule stage with a 2025 window.
As of early December 2025, FinCEN’s Special Measures listing nonetheless exhibits the cryptocurrency mixing motion as anchored to the 2023 discovering, with out a listed final-rule hyperlink, indicating the rule has not been finalized.
The hole between the NPRM and the ultimate rule creates uncertainty about how aggressively FinCEN will institutionalize surveillance expectations for mixer-linked flows.
The privacy-preserving computation wager
The panelists characterize a technical thesis: that zero-knowledge proofs, homomorphic encryption, and programmable privacy can fulfill compliance necessities with out exposing transaction graphs to blanket surveillance.
Aleo, Espresso, Zcash, and comparable initiatives construct programs that enable customers to show they meet regulatory thresholds, are non-sanctioned counterparty, have complied with tax reporting necessities, and are accredited traders, with out disclosing the complete transaction historical past.
The idea assumes regulators will settle for selective disclosure backed by cryptographic proof fairly than requiring full ledger visibility because the default.
SpruceID’s Wayne Chang brings a complementary angle: decentralized identification programs that let customers management attestations about compliance standing with out counting on centralized intermediaries.
The counterargument, implicit within the Samourai and Storm prosecutions, is that privacy-by-default architectures obscure enforcement sight traces an excessive amount of.
Prosecutors argued that Tornado Cash and Samourai enabled dangerous actors exactly as a result of the instruments didn’t distinguish between official privacy use instances and legal obfuscation.
The DOJ’s place treats privacy instruments as infrastructure that should be designed with regulation enforcement entry inbuilt, not bolted on.
That framing collapses the excellence between “device” and “service” and treats developers who deploy privacy-preserving code as operators of economic companies topic to Bank Secrecy Act obligations.
What the SEC good points from this dialog
The roundtable provides the SEC a public document on whether or not privacy-preserving know-how can meet securities regulation obligations.
The fee doesn’t regulate mixing instantly; that is, FinCEN and DOJ territory. However, it governs the issuance, buying and selling, and custody of digital property that could possibly be structured with privacy options.
If a tokenized safety makes use of zero-knowledge proofs to cover transaction particulars, does that violate broker-dealer reporting necessities?
Can an alternate buying and selling system use privacy-preserving computation to match orders with out disclosing pre-trade data to opponents whereas nonetheless meeting Regulation ATS transparency guidelines?
The roundtable panelists will doubtlessly reply these questions reside, on the document, with Chairman Paul Atkins and Commissioners Mark Uyeda and Hester Peirce current.
The timing additionally lets the SEC place itself relative to FinCEN.
If FinCEN finalizes the Section 311 mixer rule with broad restrictions, the SEC can level to its December roundtable as proof that it explored whether or not know-how may clear up the compliance drawback earlier than defaulting to prohibition.
On the opposite hand, if FinCEN softens the rule or delays it additional, the SEC’s roundtable turns into a sign that the administration is open to privacy-preserving options that meet regulation enforcement wants.
Either manner, the occasion builds a document that lets the SEC declare it consulted technologists, civil libertarians, and trade earlier than deciding the best way to deal with privacy in digital asset regulation.
The SEC now decides how a lot weight to offer privacy-preserving computation in its personal rulemaking.
If the roundtable reaches consensus that zero-knowledge proofs can meet compliance obligations, the fee can incorporate that flexibility into broker-dealer, ATS, and custody guidelines for digital property.
If the roundtable fractures into “privacy is a proper” versus “privacy permits crime” camps, the SEC defaults to present surveillance-heavy frameworks and leaves privacy advocates to litigate in court docket.
The Samourai sentences and the Storm verdict, for now, have already outlined the boundaries of legal legal responsibility.
The Dec. 15 roundtable decides whether or not there may be area inside these boundaries for privacy-preserving know-how to exist in any respect.
