EU Regulators Might Nuke Blockchain Histories to Protect Your “Precious” Personal Data

BBG News

Imagine spending years building a giant, indelible ledger, only for someone in Brussels to hand you a mop, point to all your hard work, and say, “Clean it up, or else.” The European Union’s regulators, armed with a brand-new report, have set their sights on blockchain technology—the same people who made us click “accept cookies” on every website since 2018 (no, you’re not allowed to forget your cookies, ever 🍪).

The European Data Protection Board’s report is the kind of light reading usually reserved for insomniacs. In it, they suggest—straight-faced, mind you—that fully deleting a blockchain might sometimes be the only way to comply with GDPR, their favorite four-letter acronym. (They whisper it to each other at dinner parties.)

Before anyone panics and throws their hardware wallet into the sea, some “evaluations” must be conducted, which basically means a pop quiz for your blockchain:

  • Does your blockchain have personal data? If so, bad news—you might need to talk to HR (Human Retention).
  • Why blockchain? Is there literally no other way, like, say, ancient papyrus or interpretative dance?
  • Have you considered slightly less anarchic blockchains? Private? Permissioned? Something with a user manual?
  • Are any privacy gizmos in use? Please say yes, or prepare to design an entire new blockchain—no pressure! 🔧

No blockchain left behind—except, well, possibly every blockchain, if deleting a single embarrassing transaction isn’t already built in. Data must “be erased” once you’re done with it, like gently tucking your history into a shredder.

The EDPB admits, with what I imagine is an understated shrug, that “Data deletion at the individual level in a blockchain can be challenging and requires ad-hoc engineered architectures.” (Translation: It’s like trying to un-toast bread. Good luck! 🥖🔥)

And if you can’t? “This may require deleting the whole blockchain.” A solution so elegant it’s practically kaboom. “Welcome to Ethereum! Oh wait, it’s gone now.”

James Smith, who concerns himself with “special projects” at Ethereum, sounded more than a little alarmed on LinkedIn:

“The very architecture of public blockchains like Ethereum is being challenged. Without significant pushback, we’re facing a regulatory framework that fundamentally misunderstands decentralized technology. This isn’t just about compliance headaches – it’s about whether public blockchains can legally operate in Europe.”

The take-home: Europeans may soon enjoy both the right to be forgotten and the right to forget that blockchains ever existed. 🕵️‍♂️✨
