An Eight-Year Investment Takes a Sharp Turn: Why Did Ethereum Suddenly Abandon Poseidon?

On August 13, Ethereum researcher Justin Drake announced a significant shift in Ethereum's Layer-1 cryptographic roadmap: abandoning the SNARK-friendly hash function Poseidon in favor of traditional functions like SHA2 or BLAKE2. This decision ends eight years of research and investment, marking a major revision to the post-quantum security strategy. Poseidon, introduced in 2019, was highly efficient for zkRollups and zkVMs within SNARK circuits. However, its need for prolonged cryptanalysis and the pressing timeline for quantum resistance revealed limitations. Recent breakthroughs in SNARK design, specifically using binary fields, now enable traditional, battle-tested hash functions to perform as efficiently as Poseidon within SNARKs. Benchmarks show modern laptops can now verify over a million traditional hash calls per second. This change is partly driven by accelerated concerns over quantum computing threats. Reports warn that "Cryptographically Relevant Quantum Computers" could break current blockchain signatures like ECDSA by the early 2030s, risking trillions in assets. Ethereum's response focuses on hash-based post-quantum signature schemes, deemed more quantum-resistant than some lattice-based alternatives under pressure from AI cryptanalysis. Ethereum's updated post-quantum roadmap targets a production-ready "leanVM" for signature aggregation by 2027, with full deployment across consensus, execution, and data layers by 2028. The shift to mature hash functions like SHA2 reduces reliance on newer algorithms and aligns with the goal of using widely analyzed cryptographic primitives. Other major blockchains are also preparing. Solana's core teams have independently chosen the NIST-standardized Falcon signature scheme for its compact size. Starknet plans a phased migration, starting with replacing its Pedersen hash with BLAKE2. Ethereum's move signifies a strategic pivot towards proven security foundations for the quantum era.

Etherealize CEO Calls Wall Street's Private Blockchains a 'Race to the Bottom'

Etherealize co-founder and CEO Vivek Raman criticized Wall Street's growing interest in private, permissioned blockchains, calling them a "race to the bottom." In an interview with CoinDesk, Raman argued that consortium networks fragment liquidity and return the industry to the siloed systems that blockchain technology was meant to overcome. He stated that closed networks do not interoperate, undermining two key advantages of the technology: system compatibility and liquidity concentration. Etherealize promotes Ethereum as an open, foundational layer for institutional players. Raman insists that privacy and access restrictions should be built on top of public infrastructure—at the application or L2 level—rather than creating separate, closed networks. He compared Ethereum to HTTP as a base layer, with additional permissioned and private layers akin to HTTPS. Examples of this new wave of "closed" solutions mentioned include Canton Network from Digital Asset, Circle's Arc project, and Stripe's Tempo. Raman termed this trend "consortium chains 2.0," recalling earlier initiatives like the R3 interbank consortium and the Hyperledger corporate ecosystem from 2016 that failed to gain significant traction. He reiterated his firm belief that a global, open, permissionless infrastructure is necessary as a foundational base layer. Raman previously noted in June that traditional financial institutions had begun implementing Ethereum-based solutions into real business processes.

Bitcoin Red Team, BPI, and Over 40 Companies Join Forces to Close the AI Security Gap

More than 40 cryptocurrency companies, coordinated by the Bitcoin Policy Institute (BPI), are urging leading AI labs like OpenAI and Anthropic to grant trusted security researchers access to their most advanced AI models, which hackers already possess. This request aims to protect the over $1 trillion in assets secured by open-source financial software. The letter argues that while criminals exploit these powerful models for attacks, legitimate defenders are often restricted to weaker, open-source alternatives, creating a dangerous security gap. The signatories, including major firms like Block, Coinbase, and Galaxy, propose establishing verified access programs for qualified security experts to level the playing field. The call is driven by reports of sophisticated attackers, potentially including foreign adversaries, using advanced AI to target Bitcoin infrastructure. Data from firms like SlowMist shows a significant rise in blockchain security incidents in early 2026 (182 vs. 121 in early 2025), though total losses decreased sharply to about $956 million from $2.37 billion. This trend suggests attackers are launching more frequent, lower-impact attacks. The situation is further complicated by the U.S.-China AI race, as powerful Chinese models become more widely available. The core question remains whether granting defenders equal access to cutting-edge AI will help mitigate threats or simply accelerate a cybersecurity arms race.
