According to the official blog, Circle's institutional-grade blockchain Arc has released a phased upgrade roadmap for post-quantum cryptography (PQ), planning to introduce post-quantum signature schemes at the launch of the mainnet, gradually covering full-stack layers such as private state protection, infrastructure hardening, and validator authentication.The Arc mainnet will support post-quantum signatures from the outset, using an opt-in mechanism that does not require mandatory migration or a full network reset, allowing users to independently create wallets with long-term security. The recent goal is to extend quantum resistance to the private virtual machine (VM) layer, protecting private balances, private transactions, and private payees, with public keys additionally encapsulated in a symmetric encryption layer under privacy mode.The mid-term plan is to advance the upgrade of the infrastructure layer, aligning with industry standards such as TLS 1.3, covering access control, cloud environments, and hardware security modules (HSM). The long-term goal is to complete the hardening of validator signatures. Given that Arc's block finalization time is less than 1 second, the current assessment considers the risk of quantum attacks in this phase to be relatively limited, and it will be steadily advanced after the post-quantum consensus toolchain matures.Circle also warns that attackers may adopt a "collect now, decrypt later" strategy, and institutions should plan their cryptographic migration paths as early as possible.

According to GlobeNewswire, Nasdaq-listed company ZeroStack Corp. announced that it has reached a final agreement on a $107 million financing deal anchored by 0G tokens. After the transaction is completed, ZeroStack will hold approximately 21% of the total supply of 0G tokens.According to the financing terms, ZeroStack will establish a Texas-based company called Texas Blocker to facilitate this transaction.

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 Block, the Ethereum Layer 2 project ZKsync has announced that it will officially discontinue ZKsync Lite (formerly ZKsync 1) on May 4, 2026. At that time, the network will stop producing blocks and permanently freeze the final state to ensure that balances cannot be changed after the shutdown. The team stated that this move is a "orderly planned exit" and will not affect ZKsync Era or other chains built on the ZK Stack.After Lite is shut down, the official will maintain a read-only API for at least one year to support historical data queries. Users are advised to proactively withdraw assets before the deadline for convenience, but unwithdrawn funds can still be claimed later. Data shows that there are currently about $33.9 million in assets bridged on ZKsync Lite, including approximately $24.9 million in stablecoins, $8.4 million in ETH and its derivatives, $313,000 in BTC and its derivatives, and about $231,000 in other assets.ZKsync Lite was launched in June 2020 and is regarded as the first zero-knowledge Rollup on Ethereum, supporting token transfers, atomic swaps, and NFT minting, but lacking smart contract functionality. In March 2023, the developer Matter Labs stopped development on Lite after launching Era, shifting focus to support the zkEVM system for general smart contracts.

Due to the Layer 2 solution Base announcing its transition from the OP Stack to its independently operated unified tech stack base/base, the native token OP of Optimism has dropped over 20% in price in the past 24 hours.Base stated that this move aims to improve development speed and reduce system complexity. In the future, node operators will need to migrate to the Base client to align with the hard fork. Base went live in 2023 as an OP Stack chain, and according to previous agreements, a portion of its sequencer revenue was to be submitted to the Optimism treasury. With Base transitioning to an independent architecture, this revenue stream will be retained by Base itself. Currently, the trading price of OP is $0.1436, down about 97% from its historical high of $4.84 set in 2024. In contrast, Base has not yet issued any tokens.

According to official news, Polymarket has announced an exclusive partnership with Substack.According to the announcement, Substack authors will be able to natively integrate Polymarket market data into their content, using real-time prediction market information to assist news reporting.Both parties stated that this move aims to embed prediction market data into the writing process, providing data reference support for content creators.

According to The Block, Coinbase's incubated Ethereum Layer 2 network Base has announced its separation from Optimism's Superchain ecosystem, shifting to a unified tech stack operated by Base, and abandoning external dependencies on OP Stack as well as Flashbots and Paradigm.This change aims to reduce the coordination overhead of maintaining code across multiple teams, simplifying the system through optimizations based on open-source components like Reth, while maintaining the "Stage 1" rollup status. It plans to be temporarily compatible with OP Stack, but future hard forks will require migration to the new Base client. The upcoming hard fork includes Base V1 (supporting Fusaka and switching to TEE/ZK proofs), and subsequent versions will synchronize with the Ethereum Glamsterdam upgrade; the blog emphasizes the protocol's openness and welcomes alternative implementations.

According to The Block, Coinbase's Ethereum Layer 2 network Base announced that it will no longer rely on Optimism's OP Stack and Superchain architecture, instead opting for a "unified stack" operated independently by Base.According to the official blog, Base will integrate core components that were previously scattered across multiple teams and code repositories (including key modules like the sequencer) into a unified codebase "base/base" to reduce coordination and maintenance costs, and to optimize deeply for its own needs.At the same time, Base will also reduce its external dependencies on Flashbots, Paradigm, and others. In terms of governance, Base will adjust the security committee structure, replacing the original Optimism-related seats with newly added independent signers.Despite the shift towards an autonomous technical architecture, Base stated that the protocol will remain open source and publicly standardized, welcoming third-party developers to create independent clients and maintain cross-upgrade compatibility. Base is currently the largest network in the OP Stack Superchain ecosystem.
