Grayscale Says Bitcoin Pressure Came From ETF Mechanics, Not Quantum Fears
Grayscale pushed back on the idea that Bitcoin’s recent weakness was driven by quantum-computing fears, arguing instead that the decline reflected broader de-risking and the mechanics of ETF redemptions. The firm said large operational BTC transfers amplified selling pressure, with roughly 115,600 BTC moved since GBTC converted to an ETF.
Solana Advances Falcon-Based Plan for Post-Quantum Security
Solana developers and ecosystem partners are moving to adopt the Falcon post-quantum signature scheme as the core of a phased quantum-readiness roadmap. The plan is designed to protect wallets against future quantum threats while preserving Solana’s high-throughput performance profile.
Hoskinson Says Bitcoin’s Quantum Plan Risks Stranding Its Oldest Coins
Charles Hoskinson has sharpened the debate over Bitcoin’s post-quantum future by arguing that BIP-361, the draft proposal meant to protect the network from a future break in current signature schemes, would not merely harden Bitcoin against a distant technical threat. In his view, the plan would force a migration that many of the network’s oldest […]
BitMEX Pitches ‘Canary Fund’ as Alternative to a Bitcoin Quantum Coin Freeze
BitMEX Research has injected a new fault line into Bitcoin’s post-quantum security debate with a proposal that would wait for hard evidence of a cryptographic break before triggering defensive action. The idea centers on an evidence-first “canary fund” designed to react only when a quantum attack is proven on-chain, setting it directly against BIP-361’s more […]
BIP-361 Wants to Turn Quantum Risk Into a Market Pressure Campaign
BIP-361, titled Post Quantum Migration and Legacy Signature Sunset, would push Bitcoin toward a long, staged break from legacy ECDSA and Schnorr signatures by making inaction increasingly costly for holders who leave funds in quantum-vulnerable outputs. Rather than offering explicit rewards for upgrading, the proposal tries to convert future cryptographic risk into a private financial […]
Grayscale outlined three responses for Bitcoin’s quantum‑vulnerable coins
Bitcoin’s quantum-risk debate is moving out of the realm of theory and into the realm of governance. Grayscale has outlined three possible paths for dealing with roughly 1.7 million BTC held in early pay-to-public-key outputs that could, in theory, become vulnerable to future quantum attacks.
Circle lays out quantum-resistant roadmap for Arc L1 to protect $32 billion in USDC
Circle has laid out a quantum-resistance roadmap for Arc, its Layer-1 network built for stablecoin finance, setting a phased plan to protect wallets, transactions, validators and infrastructure from future quantum threats. The roadmap presents quantum security not as a distant research topic, but as a practical engineering priority for a network expected to support long-lived […]
CZ says crypto can adapt to quantum computing, but Satoshi‑era Bitcoin faces acute risk
Changpeng Zhao has urged the crypto industry to treat quantum computing as a solvable technical challenge rather than a reason for panic. He argued that the right response is not fear, but a deliberate transition toward post-quantum upgrades that can strengthen protocols and future transactions.
Google paper finds far fewer qubits needed to break ECC, sharpening quantum threat to crypto networks
Google’s Quantum AI team has published a whitepaper arguing that the quantum resources needed to break elliptic-curve cryptography are far lower than previously believed. The revised estimate narrows the gap between theory and practical attack capability, raising new urgency around the security of on-chain signatures and exposed wallet keys.
Ethereum forms Post‑Quantum team to harden protocol; aims to finish L1 upgrades by 2029
Ethereum developers have formally launched a dedicated Post-Quantum team, signaling a more organized push to prepare the network for a future in which quantum computing could threaten today’s cryptographic standards. The announcement turns a long-discussed technical risk into a defined coordination effort with its own roadmap, public resources and implementation track.
