Google AI whitepaper: ‘Algorand is the perfect example of post-quantum computing’ – ALGO jumps 24%

Google AI's recent whitepaper on quantum computing vulnerabilities has triggered a significant 24% price surge for Algorand (ALGO), with its daily volume increasing nearly fivefold. The paper, a collaboration between Google Quantum AI, UC Berkeley, and the Ethereum Foundation, highlighted Algorand as a prime example of a blockchain proactively implementing post-quantum cryptography (PQC). It specifically commended Algorand's use of Falcon digital signatures for smart contracts and state proofs, positioning the network well for a future migration to a post-quantum standard. This news catalyzed a strong bullish move, allowing ALGO to break out of its prolonged trading range between $0.08 and $0.10. The rally saw bulls reclaim the $0.082 support level and push toward the range highs. While the surge has cleared a cluster of short liquidations, it now faces a key resistance zone around $0.10-$0.11. Analysts suggest that holding above $0.095 could signal a bullish continuation, while a drop below would indicate a return to the previous range-bound trading.

New Bitcoin Post-Quantum Work Undercuts ‘No One Is Building’ Claims

Bitcoin core developer Matt Corallo refutes claims that no serious work is being done on post-quantum cryptography for Bitcoin, pointing to Blockstream's new proposal, OP_SHRINCSVERIFY. This opcode enables SHRINCS, a hybrid hash-based signature scheme combining stateless and stateful elements, aiming for efficient 324-byte signatures with static backups. The topic is gaining traction, with multiple sessions on quantum risks and solutions scheduled at the OPNEXT 2026 conference, featuring speakers from institutions like BlackRock and Coinbase. While SHRINCS offers significant size advantages over NIST alternatives, it remains an open research proposal with unresolved questions. The development underscores that Bitcoin's post-quantum efforts are advancing with concrete proposals, moving beyond theoretical discussion.

‘Time to go full PQ’ – Ethereum Foundation launches post-quantum push

The Ethereum Foundation (EF) has declared post-quantum (PQ) security a top strategic priority, aiming to accelerate its development with a target to "go full PQ" by 2026. A dedicated team has been formed to lead this initiative, focusing on making Ethereum quantum-resistant. The EF is offering a $1 million prize to improve the Poseidon hash function as part of its emphasis on hash-based cryptography. PQ developer networks are already in progress, and a formal roadmap will be released soon. In contrast, the Bitcoin community remains divided on the urgency of quantum threats. Some analysts suggest that if it lags in PQ readiness, Ethereum could significantly outperform Bitcoin in returns, potentially by 200%.

From Principles to the Future: How Quantum Computing Reshapes the Security Landscape of Blockchain

Summary: This article analyzes the real quantum computing threat to blockchain, arguing timelines for cryptographically relevant quantum computers (CRQCs) are often exaggerated. While "Harvest Now, Decrypt Later" (HNDL) attacks necessitate an immediate shift to post-quantum encryption for long-term data secrecy, the transition for digital signatures is less urgent as they are not vulnerable to HNDL attacks. Most blockchains (e.g., Bitcoin, Ethereum) primarily use signatures, not encryption, so they face the threat of future signature forgery, not immediate decryption. However, Bitcoin requires urgent planning due to its slow governance, the need for active user migration of funds, and the risk of losing billions in vulnerable, possibly abandoned coins. Privacy chains with encrypted on-chain data are more immediate HNDL targets. The article cautions against a rushed adoption of immature post-quantum signatures (which are larger and riskier to implement) and zkSNARKs, advising a measured approach. It recommends immediate deployment of hybrid encryption, planning for blockchain migration, prioritizing implementation security (bugs are a bigger near-term risk than quantum computers), and maintaining perspective on quantum computing announcements.
