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.

XRP Has Undergone the Most Negative Period in Its History Over the Last Three Months, But Data Doesn't Show It

XRP has experienced its most negative investor sentiment in three months as the price failed to recover as expected, according to data from Santiment. Comments across social media platforms show retail investors growing significantly more pessimistic, a trend likely to persist in the short term with the price below $1. However, blockchain activity on the XRP Ledger tells a different story. In the last 24 hours, the network recorded 49,929 active addresses, the highest figure in over two months. This recent surge in activity, following a period of historically low engagement earlier in July, presents a key contrarian signal. Santiment suggests that the combination of high on-chain activity and extreme negative sentiment creates a scenario that could appeal to XRP bulls. The platform indicates that if XRP maintains its current technical structure and demand recovers, the present pessimism may later be viewed by cryptocurrency users as a discount buying opportunity.

Grayscale Highlights Three Factors Contributing to the Long-Term Growth of Bitcoin's Popularity

Grayscale Research Head Zach Pandl highlighted three structural trends that could drive long-term Bitcoin adoption, regardless of short-term price volatility. First, persistent U.S. fiscal deficits and rising public debt (forecast to reach 120% of GDP by 2036) may increase investor interest in scarce assets like Bitcoin. Second, blockchain infrastructure is entering regulated finance, with tokenized assets (exceeding $34B) and stablecoins creating new regulatory frameworks that bridge crypto and traditional markets. Third, a generational shift in portfolio construction sees younger investors more willing to hold digital assets. Institutional surveys indicate 73% plan to increase crypto allocations by 2026. Adoption channels are widening via Bitcoin ETFs and corporate treasury holdings. Grayscale argues these factors—fiscal trends, blockchain integration, and demographic change—are likely to persist beyond any single market cycle.

Bitwise Plans to Launch Solana Staking ETF with First Tokenized Shares

Bitwise Asset Management plans to tokenize shares of its exchange-traded funds (ETFs) on a blockchain, starting with a potential tokenized version of its Solana Staking ETF (BSOL). Through a partnership with Superstate, the company aims to offer investors a choice between traditional ownership recorded via the Depository Trust Company and a blockchain-based record maintained by Superstate's infrastructure. This initiative does not create new securities or alter the underlying funds; it only changes the method of recording ownership. Tokenized shares would carry the same rights as traditional shares but would not be freely transferable outside the approved system. Bitwise manages around $9 billion in assets across more than 70 products. The move towards tokenization occurs alongside internal restructuring, including a recent 14% staff reduction. The effort reflects a broader trend of placing regulated securities on blockchain without changing their legal status, focusing more on modernizing infrastructure than creating new assets. The company cautions that the initiative remains subject to legal and regulatory approvals, with no guarantee that tokenized shares for BSOL or any other fund will become available.

Expert Analyst Analyzes Current Actions of Major Players in the Bitcoin Market

Cryptocurrency analyst Benjamin Cowen analyzes the behavior of major Bitcoin investors. He notes that whale activity indicators should not be viewed as direct bull or bear signals, as spikes often occur around local price peaks or troughs. Currently, blockchain data shows a significant lull in large whale transactions, with volumes at very low levels reminiscent of the August 2018 recession period. Historically, whale transaction metrics peaked during major bull markets like 2017 and 2021. The analysis also reveals a redistribution among large Bitcoin holders. The share of wallets holding 1,000 to 10,000 BTC has decreased from about 30% to 20%, while the share of wallets holding 100 to 1,000 BTC has increased from 20% to 25-26%. Cowan suggests blockchain activity could pick up soon and advises closely monitoring whale movements to gauge whether the recent market volatility is ending.

Shinhan Asset Management and Plume Team Up for Tokenized Fund Pilot

South Korea's Shinhan Asset Management has signed a Memorandum of Understanding (MOU) with blockchain network Plume to develop a pilot version of a tokenized fund denominated in Korean won. The pilot will use Shinhan's ultra-short-term bond fund as the underlying asset, with BlackRock's BUIDL tokenized fund serving as a model for issuance and distribution. The project aims to test the compliance of tokenized investment products, including operations like whitelisted transfers, on-chain activities, KYC, and AML measures. Shinhan stated the pilot will explore the use of won-denominated financial products in on-chain markets, which have traditionally focused on dollar-denominated assets. This initiative follows other Shinhan Group blockchain projects, such as Shinhan Card's partnership with the Solana Foundation for stablecoin payments and Shinhan Bank's 2023 pilot for cross-border stablecoin transfers.

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.
