Coinbase & James Harper Sound Alarm: IRS ’Real-Time’ Blockchain Surveillance Threatens User Privacy

Big Brother wants your ledger—and crypto giants are pushing back.

Coinbase and digital rights advocate James Harper just dropped a red alert: The IRS could soon track every crypto transaction like a hawk stalking prey. Their weapon of choice? Unrestricted access to blockchain records.

The Surveillance Playbook

Imagine tax authorities watching your wallet moves in real time—no warrants, no waiting. Harper calls it 'financial strip-searching.' Coinbase warns this could bulldoze the pseudonymity that makes crypto… well, crypto.

Why This Stings

Blockchains don’t forget. Once the IRS gets a master key, every coffee-bought-with-Bitcoin becomes audit fodder. 'It’s like giving the taxman a live feed of your Venmo,' scoffs one trader, 'except you can’t hide behind that 🍕emoji.'

The Irony Department

Meanwhile, Wall Street banks still settle trades via fax. Priorities, people.

This isn’t just about taxes—it’s about who controls the financial future. Will crypto’s promise of sovereignty survive the bureaucrats’ spreadsheet fetish? Grab your popcorn (and a VPN).

The Supreme Court’s refusal means special rules for crypto

By refusing to hear the appeal, the Supreme Court leaves the First Circuit’s ruling intact. For now, Americans using crypto exchanges have no Fourth Amendment protection over transaction logs held by third parties.

Privacy advocates hoped this case WOULD extend the narrow Carpenter v. United States (2018) exception, which required warrants to access historical cell-site data, to financial platforms.

But the Court’s silence when refusing review signals no new legal guardrails will emerge for now. This also means crypto platforms and other digital services cannot refuse requests for user data from the IRS and other related federal agencies.

Harper’s lawsuit claimed the ruling strips “millions of Americans” of meaningful privacy over digital financial data. Coinbase, backing Harper via an amicus brief filed in April, warned that the IRS dragnet allows reconstruction and future tracking of user activity—“a real‑time monitor” of every transaction.

Chief Legal Officer Paul Grewal emphasized that without limits, Fourth Amendment protections over bank accounts, emails, and phone records could evaporate—and that digital platforms should receive no less privacy protection than physical mail.

The TRUMP administration urged the Court to reject the appeal, arguing Harper “lacks any reasonable expectation of privacy in Coinbase’s records.” They maintain that users voluntarily share data with platforms, forfeiting Fourth Amendment protection.

Other cases are challenging subpoenas to access digital data

X (formerly Twitter), now under Elon Musk, filed its own amicus brief in April, warning that broad, suspicionless subpoenas pose a threat not just to financial platforms but social media too.

X’s filing stated that the government’s ability to snoop on private accounts without warrants endangers free expression and data privacy on all digital platforms.

With no Supreme Court intervention, the First Circuit’s interpretation will continue to influence similar cases across the country, granting the IRS the power to subpoena digital financial data stored by custodial services.

There’s growing momentum from privacy groups and bipartisan lawmakers to update Fourth Amendment protections for digital data. So, Congress or future litigation may eventually challenge the doctrine’s place in the crypto era.
