Investment bank Mizuho stated that after acquiring the stablecoin infrastructure company BVNK, Mastercard is expected to become a "network connector" linking crypto assets with fiat currency systems, further expanding its payment ecosystem.Analysis indicates that stablecoins will not undermine Mastercard's core card payment business; instead, they will serve as an "accelerator" for its network, particularly in areas such as B2B cross-border payments, remittances, and the creator and gig economy, facilitating faster, lower-cost, 24/7 capital flow. Mizuho maintains an "outperform" rating on Mastercard and sets a target price of $666.Analysts believe that in the aforementioned emerging scenarios, the penetration rate of traditional bank cards remains relatively low, and stablecoins are expected to fill this gap, while card payments will continue to serve as the core entry point for consumers. It is reported that Mastercard has agreed to acquire BVNK for up to $1.8 billion. This transaction is seen as an important step in continuing its role as a "network connector," expanding its business into the conversion and settlement between stablecoins and fiat currencies.Against the backdrop of a gradually loosening regulatory environment and traditional payment giants like Visa and Stripe accelerating their layout in stablecoins, stablecoins are becoming an important growth direction for the global payment system.

Bitlayer ($BTR) has plummeted 80% since yesterday afternoon, with the price dropping from $0.2 to $0.04. On-chain data shows that within a day, 41% of the circulating supply (about 140 million coins) of $BTR flowed into the Bithumb exchange, which is suspected to be the main dumping ground or price manipulation site for this spot trading.

The Ethereum Foundation today released a systematic explanation regarding the evolution of the roles of L1 and L2. The core point indicates that as the ecosystem matures, the primary goal of L2 has shifted from "scaling Ethereum" to "providing differentiated functions, customized services, and autonomous controllable areas," while scaling has become a secondary focus.The Foundation has redefined the roles of L1 and L2 as follows:· L1: As a permissionless, highly resilient global settlement layer, it undertakes the functions of shared state, liquidity, and DeFi hub, and must continue to scale while maintaining censorship resistance, open source, privacy, and security.· L2: While developing its own on-chain economy, it will extend Ethereum's core attributes to a broader user base, forming a "full-spectrum" ecosystem.The Foundation clarifies that L2s with the highest integration with L1 should pursue synchronous composability, complete interoperability, shared liquidity, and Stage 2 mechanisms. A large number of L2s with diverse business models and technical expertise will continue to play an important role, providing functionalities that L1 does not possess.The Ethereum Foundation stated that it will continue to invest in technology to help L2 smoothly extend L1's core attributes and securely access cross-layer liquidity, while emphasizing that L2 must maintain transparency and verifiability of its security attributes.

Cybersecurity company CUJO AI has officially launched a network-layer cryptocurrency investment fraud detection capability designed for network service providers (NSP), which can identify fraudulent activities that bypass application layer and platform layer protections. CUJO AI stated that modern cryptocurrency investment scams often rely on rotating domain names, wallet interactions, and social engineering tactics, making it difficult for a single platform to grasp the full picture; the network layer is a key location where such threats are concentrated.According to Chainalysis data, global losses from cryptocurrency-related scams and fraud are estimated to reach $17 billion by 2025, with the majority of victims being ordinary users rather than institutional traders.

The Bitcoin Layer 2 network Stacks announced that its SIP-034 upgrade has been implemented on the mainnet, which can increase the network processing capacity of some DeFi applications by up to 30 times.The upgrade optimizes transaction processing limits by resetting only the exhausted single resource limit instead of all limits, thereby utilizing block capacity more efficiently. Alex Huth, the product lead at Stacks Labs, stated that this improvement has the greatest impact on complex and read-intensive DeFi applications, such as concentrated liquidity and advanced automated market maker (AMM) designs. Although the upgrade does not directly change the STX token economics, it is expected to indirectly increase transactions and fees as network activity increases.

According to the official announcement, the globally leading digital asset trading platform Gate has announced a partnership with the Ethereum Layer2 network Abstract and the DeFi protocol Aborean Finance deployed on that chain, launching a liquidity incentive campaign called "Gate Abstract Incentive Carnival" aimed at the Abstract ecosystem. This program revolves around the GTBTC/GUSD liquidity pool, integrating transaction fee sharing, $ABX governance token rewards, and ecological XP incentive mechanisms, constructing a multi-layered revenue structure of "transaction fees + tokens + ecological points" to strengthen the platform's capabilities in on-chain liquidity and multi-chain collaboration.According to the rules, users can obtain LP certificates and share transaction fees after adding liquidity on Gate. If they choose to stake in Aborean, they can receive governance token rewards; during the event, they can also earn double XP and exclusive badges from the Abstract ecosystem. This collaboration precisely matches wallet binding and on-chain incentives, enhancing reward transparency and verifiability, and under the backdrop of the maturation of account abstraction and Layer2 infrastructure, it forms a new exploration direction in multi-chain collaboration and on-chain incentive mechanism design.

According to The Block, Ethereum researchers demonstrated a proof of concept for "native Rollups" based on the execution client Ethrex, implementing EIP-8079 through the addition of an EXECUTE precompile, which directly replays and verifies Layer 2 block state changes on the Ethereum base layer.This solution does not rely on zero-knowledge proofs or fraud proofs, but instead is executed and confirmed by Ethereum itself to validate Rollup transaction validity. The related contracts are used to track Rollup state, bridge cross-layer messages, and verify withdrawals based on Merkle-Patricia proofs. Developers claim that native Rollups can simplify long-term maintenance of Layer 2, allowing them to directly inherit Ethereum's security and upgrade properties, and they are still in the exploration and proof of concept stage.

The digital asset trading platform Gate officially launched Gate for AI, introducing the industry's first unified AI entry point that integrates five major capabilities—CEX, DEX, wallets, real-time information, and on-chain data—under the same interface system.Gate for AI adopts a dual-layer capability structure. In this architecture, MCP provides standardized basic interfaces, covering functions such as market data, account information, trade execution, and on-chain data queries, enabling AI to quickly access and utilize platform capabilities; Skills encapsulates higher-level strategy modules based on this, such as market scanning, position range assessment, and risk analysis, helping AI make more complex trading decisions.In addition, Gate for AI supports multi-platform calls, lowering the usage threshold and catering to users with different needs. This release marks the upgrade of the exchange's capabilities from interface products to directly callable AI infrastructure, pushing digital asset trading into the era of Agent-native.

According to CoinDesk, Davide Crapis, head of AI at the Ethereum Foundation, stated that Ethereum's goal is not to merge with AI at the computational level, but to become a coordination and verification layer for the AI world. He pointed out that as more digital activities are handled by AI systems, if these systems are controlled by centralized entities, the values advocated by the crypto movement, such as decentralization, self-sovereignty, anti-censorship, and privacy, will be eroded.Ethereum's AI strategy includes two main directions: first, decentralized AI coordination, providing infrastructure for identity recognition, trust establishment, and payment exchange for increasingly popular AI agents, allowing agents to discover each other, assess reputation, and route payments through public registries via standards like ERC-8004; second, introducing core principles such as privacy, openness, and anti-censorship into the AI field, promoting more AI processing to occur locally on user devices, allowing users to retain control over their data and identity.Crapis emphasized that in a future where AI can impersonate humans, cryptographic keys will become even more important. Even if Ethereum does not provide the "brain" of AI, it can help govern its operating environment.
