ARK Invest's Director of Digital Asset Research, Lorenzo, stated that the latest improvement proposals from Solana and Ethereum are surprising. The market has indicated that Hyperliquid and others are posing strong competition, but the relevant communities are still taking time to adjust inflation arrangements and CU restrictions, which may further decrease the competitiveness of applications. He believes that L1 should prioritize how proposals can enhance network competitiveness, promote growth, and attract more consumer-grade applications and users.Lorenzo pointed out that for Solana, this is certainly not the time to be entangled in the value accumulation of token holders versus cash flow, or to increase the costs for application developers. It is essential to first prove that the pie can be expanded 100 times before discussing how to allocate it. Although in the future, it will be necessary to price high resource-consuming transactions more finely and address token value accumulation, if market share is seized by HYPE, there will be no value to accumulate. The current priority should be to expand the pie 100 times.

The Arbitrum development team stated that they are introducing zero-knowledge (ZK) proofs into the Arbitrum platform to achieve a multi-proof settlement model. Through ZK proofs, the settlement time of Arbitrum blocks to Ethereum L1 is expected to be reduced from several days to several hours, while enhancing user, cross-chain bridge, and protocol capital efficiency, and maintaining security through the multi-proof mechanism. Related capabilities are aimed at Arbitrum One and dedicated chains based on the Arbitrum platform. Offchain will subsequently submit upgrade proposals to the DAO.Current progress includes: the ability to run the same state transition functions in SP1 zkVM as in optimistic execution, generating ZK proofs for real mainnet block production; Stylus's WASM contracts can be proven alongside Solidity contracts; the team has launched an independent Rust verifier, making ZK proofs a first-class mode alongside standard verification; the BoLD settlement protocol has supported the acceptance of ZK proofs and is endorsed by a fast confirmation committee, while the original dispute games still serve as a fallback path, forming a multi-proof architecture that coordinates ZK proofs, proof committees, and fraud proofs.The team claims to be continuously reducing proof costs and will gradually merge related code into the Nitro main production path. The next steps include further optimizing proofs and shifting to Reth-based execution, completing L1 message inbox proofs, and integrating ZK settlement capabilities into node configurations for on-demand activation across chains.

Matthew Sigel, the Head of Digital Asset Research at VanEck, stated that if the U.S. CLARITY Act is passed, it will trigger "an enormous relief rally" in L1 tokens.Sigel's remarks focus on the potential impact of regulatory progress on native assets of public chains. The CLARITY Act aims to provide a clearer regulatory framework for digital assets, and the market generally views it as one of the important legislative variables affecting the risk appetite for crypto assets.

Justin Drake posted on the X platform that Ethereum L1 will no longer use the SNARK-friendly hash function Poseidon, which has dominated since 2019, and will instead turn to traditional hash functions such as SHA2 or BLAKE2s.This adjustment is based on advancements in the field of SNARK design, shifting the focus from "SNARK-friendly hashing" to "hash-friendly SNARK." By aligning Boolean operations in traditional hashing with binary field native, the proof performance of traditional hashing in SNARK has reached 1 million per second, with an overhead of about 100 times.Research from Binius and Flock has driven relevant progress. The Ethereum Foundation's post-quantum team is advancing this route, with a roadmap that includes deploying production-level leanVM in 2027, and deploying in the consensus layer, execution layer, and data processing layer in 2028.Justin Drake also stated that the enhanced capabilities of AI in cryptanalysis have recently led to setbacks for the lattice-based scheme HAWK and the homomorphic scheme SQIsign, with hash-based schemes being used for post-quantum signatures on the blockchain. The trend of open-source automated research is also accelerating, with SNARK.fast achieving 1.8 million BLAKE3 proofs per second.

Ten European financial institutions have jointly launched Regulated Layer One (RL1). This network has been established and is operational in Luxembourg as a European cooperative, targeting regulated financial markets and tokenized assets. The founding members of RL1 include ABN AMRO, Cecabank, Chartered Investment, Crédit Mutuel Alliance Fédérale, DekaBank, DZ BANK, LBBW, Natixis CIB, SC Ventures, and Seturion. RL1 indicates that each member has equal decision-making power in network governance and development.This private permissioned network is based on the infrastructure developed by the German fintech company Secure Worldwide Interbank Asset Transfer (SWIAT), which has transferred ownership of the network to the cooperative. SWIAT states that the platform has processed over 50 transactions amounting to more than 700 million euros during its three years of production use. The intended uses of RL1 include digital currencies, tokenized bonds, collateral, and blockchain-based settlement. RL1 will be led by former SWIAT Managing Director Henning Vollbehr, and KfW and L-Bank will continue to support the initiative. RL1 is in discussions with more institutions, including NatWest, about joining the network.

Forma announced on the X platform that after careful consideration, it has decided to shut down Forma Chain due to the unsustainability of operating the chain.As a transitional solution, Modularium and Forma NFT will migrate to Ethereum L1 to ensure the permanent existence of artworks and the marketplace. After the migration, NFTs will still be accessible and can be traded on OpenSea or other Ethereum marketplaces, with Modularium continuing to serve as the display platform for these collectibles.The team strongly recommends that users withdraw funds via the Forma bridge. Any funds not withdrawn in a timely manner will be manually migrated to an EVM-compatible chain to be announced later.The team emphasizes that user funds and NFTs are safe, and a specific timeline and migration steps will be announced subsequently.

According to official news, the one-stop trading platform Dango team announced that due to various reasons, the project has no viable path to achieve sustained commercial success and has decided to shut down. The team emphasized user fund safety, withdrawal restrictions will be lifted in the short term, and advised users to close positions and withdraw funds as soon as possible, while reminding that current liquidity is expected to be thin, and caution should be taken regarding slippage risk.At 20:00 Beijing time on July 29 (12:00 UTC), Dango will stop trading, and remaining positions will be closed at oracle prices. DLP gold deposits will be unlocked, and all funds will be returned to users' spot accounts in the form of USDC.At 20:00 Beijing time on August 13 (12:00 UTC), the Dango L1 blockchain will cease operation. At that time, any deposits that have not been withdrawn will be refunded to the user's original Ethereum deposit address.

TxFlow L1 announces the launch of its second Channel Probly, which is the first prediction market application developed based on the TxFlow Improvement Protocol 3 (TIP3). When Probly goes live, it will offer 172 real-time markets covering over 7,000 events, including continuous rolling markets with a minimum duration of 5 minutes, and supports full on-chain settlement and TxFlow L1 shared financial infrastructure.Probly covers 15 categories including politics, sports, crypto, finance, and geopolitics, and provides prediction markets related to BTC, ETH, SOL, and XRP price trends for 5 minutes, 15 minutes, 1 hour, and 4 hours. Users can access Probly through an email-based embedded wallet without managing mnemonic phrases, and can also connect compatible wallets such as MetaMask, Coinbase Wallet, Phantom, and Uniswap Wallet. Eligible settlement amounts will be automatically credited in USDC after the event resolution, without the need for separate claims.

Ethereum co-founder Joseph Lubin stated that Ethereum L1 transaction fees should remain low to promote ecosystem growth. It is expected that in the next 2 to 3 years, tens of thousands of companies will deploy on Ethereum L1, L2, and permissioned EVM networks, achieving cross-layer interoperability.Lubin believes that large-scale adoption will enhance the monetary premium of ETH and the total transaction fee revenue of L1. At the same time, staking and other locking mechanisms will reduce circulating supply. If ETH returns to a net destruction state, its value is expected to rise further.

According to monitoring by Catcher Predict, in the market prediction event on Polymarket for "Dota 2: L1ga Team vs 4ikibamboni - International Europe Closed Qualifiers Playoffs," the "Total Kills Exceeding 45.5 in the First Game" sub-market's "Exceeding" option win rate has experienced significant fluctuations, soaring from 50% an hour ago to the current 95.5% (a fluctuation of 45.5%). Please note the impact of related breaking news.

According to analysis by BlockSec Phalcon (@Phalcon_xyz), the RollupProcessorV3 contract of Aztec Network was attacked, resulting in losses exceeding $2.15 million. The root cause was that numRealTxs was not effectively bound to the transaction set enforced by the ZK proof, leading to discrepancies in the proof verification path and the L1 settlement logic's interpretation of the transaction list.The attacker exploited this vulnerability to move real deposits to slots not processed by the settlement logic, bypassing the decreasePendingDepositBalance() function, creating unsecured private balances out of thin air, and then withdrawing through the normal settlement process, involving a total of seven assets.

Aptos posted on platform X stating that Aptos is the first L1 to support dynamically scheduled formal verification, which can be mathematically proven to operate as designed. Aptos claims that AI writes specifications, mathematically proves their correctness, and Move Prover serves as the oracle, which is the trust layer between the market and machines.

Aptos announced that after the governance vote passes, it will become the first Layer 1 public chain to provide a native encrypted mempool. This feature achieves complete confidentiality of transaction intentions, does not affect transaction speed, and aligns the trust assumptions with the network itself, aiming to protect users from frontrunning at the protocol level.
