D-Wave Shares Jump 20% After AT&T Expands Quantum Computing Agreement
D-Wave Quantum shares surged after AT&T signed an agreement to expand its use of the company’s quantum computing technology across network operations. QBTS closed at $19.51 on Monday, July 27, 2026, gaining 20.36% from the previous session, as investors responded to evidence that the telecommunications group plans to apply quantum optimization to practical infrastructure challenges.
EIP-8292 Post-Quantum Attestation Aggregators Draft Released
Ethereum developers have introduced EIP-8292, a draft core proposal defining a specialized aggregator role for a potential post-quantum consensus system. The proposal would move the computationally intensive aggregation of validator attestations to opt-in, higher-specification nodes, allowing ordinary validators and block proposers to avoid generating complex cryptographic proofs during every slot. EIP-8292 was created on June […]
BitGo Rolls Out Quantum Risk Management Tools for Institutional Bitcoin Wallets
BitGo has introduced new quantum risk management capabilities for its Bitcoin custody infrastructure, giving institutional clients tools to score, track and reduce cryptographic exposure across UTXO-based wallets. The update is integrated directly into the company’s existing multi-signature custody architecture.
Cardano Vision 2026 Proposal Outlines Post-Quantum and Scalability Roadmap
Input Output Research (IOR) has introduced the Cardano Vision 2026 program, a restructured research and development proposal designed to address long-term infrastructure challenges including post-quantum security, decentralized identity, and multi-layer scalability. The initiative, led by a consortium of nine organizations, seeks to move theoretical blockchain science into practical engineering implementations over the next two years.
Algorand Foundation sets post-quantum security roadmap
The Algorand Foundation has outlined a post-quantum security roadmap aimed at moving the protocol toward broad quantum resilience before the end of 2027. The plan covers user wallets, developer tooling and deeper protocol mechanisms rather than a single isolated upgrade.
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 […]
