Quantum attacks could worsen without proof of ownership: Near One

NEAR Protocol warns quantum computers could break blockchain cryptography and compromise wallet ownership verification. Without proof-of-ownership systems, protocols face freezing assets or enabling theft. NEAR is implementing FIPS-204, a post-quantum signature solution, by Q2. Ethereum, Solana, and Bitcoin are also developing quantum-resistant defenses as Google researchers suggest functional quantum computers could arrive sooner than previously expected.
Key takeaways
- 1NEAR Protocol is implementing FIPS-204, a post-quantum signature solution, launching on testnet by Q2 2026.
- 2Google researchers warn quantum computers could break Bitcoin's cryptography within 10 minutes, enabling theft via on-spend attacks.
- 3Ethereum, Solana, and Bitcoin are all developing quantum-resistant defenses; Ethereum targets protocol-level solutions by 2029.

UAE-regulated stablecoins to develop AED-USD conversion rails for institutional settlement
UAE regulators are backing a new settlement infrastructure connecting AE Coin and USDU stablecoins, enabling near-instant AED-USD conversions for institutional payments. Powered by Al Maryah Community Bank, the framework targets treasury flows and cross-border settlement within the UAE's regulated payment token regime. This strengthens UAE's position as crypto's fastest-growing regional hub, signaling institutional crypto adoption momentum relevant to Indian investors monitoring emerging market infrastructure.
