The UK government has made clear it won’t be swayed by Washington’s displeasure over proposed social media restrictions targeting children under 16. Technology Secretary Liz Kendall confirmed on June 9 that Britain will move forward with the regulations, brushing aside concerns raised by the US embassy just days earlier.

What the UK is actually doing

The proposed rules would impose age or functionality restrictions on social media platforms for users under 16. A public consultation ran from March 2 to May 26, 2026, pulling in over 116,000 responses.

This isn’t the UK’s first swing at tech regulation. The Online Safety Act of 2023 already established a framework for holding platforms accountable for harmful content. The Children’s Wellbeing and Schools Act of 2026 built on that foundation.

The enforcement teeth are real. Under the Online Safety Act, platforms that fail to meet child safety duties face fines of up to 10% of global revenue or £18 million, whichever is higher.

Australia already moved in this direction, introducing similar under-16 rules on December 10, 2025. That rollout impacted roughly 4.7 million accounts by mid-December 2025.

The US pushback and why it didn’t work

The US embassy raised its objections on June 5, 2026, warning that the regulations would place a disproportionate burden on American companies. There were also questions about how age verification would actually work for users between 13 and 16, a cohort that currently accesses most platforms under existing terms of service.

Kendall’s response was effectively: we hear you, and we’re doing it anyway. Prime Minister Keir Starmer has positioned child safety measures as a core policy priority.

Why crypto and Web3 should be paying attention

Age verification at scale requires robust identity systems. That’s precisely the space where decentralized identity (DID) protocols and zero-knowledge proof solutions have been positioning themselves.

Decentralized social media platforms would face an uncomfortable question: do you comply with UK age restrictions, or do you become effectively illegal in the country? The UK has shown it’s willing to pursue aggressive remedies including ISP-level blocking.

Ten percent of global revenue is the kind of penalty designed to make even the largest companies take notice. If that enforcement model proves effective for child safety, expect regulators to extend the template to other areas: financial promotion rules, anti-money laundering obligations, consumer protection mandates.
