According to The Block, BNB Chain is building a new Layer 1 blockchain designed specifically for agent trading, targeting transaction pre-confirmation in under 50 milliseconds, and suppressing MEV behaviors such as sandwich attacks by eliminating the public mempool (adopting the TxStream mechanism). The new chain will also reserve block space for oracles, liquidations, and cross-chain bridges via PriorityLane, with a designed throughput target exceeding 100,000 TPS, and supporting sub-second block finality. This chain will become the fourth chain in the BNB Chain ecosystem, connected to BNB Smart Chain via a native bridge, with BSC serving as the settlement hub. The testnet is planned to launch at the end of 2026, and the mainnet is expected to deploy in early 2027.
BNB Chain is developing a new Layer 1 blockchain designed for Agentic Trading, releasing the first detailed architectural information after months of research and development. According to BNB Chain's disclosed technical roadmap for the second half of 2026, the new chain will run in parallel with the existing BNB Chain ecosystem, targeting transaction preconfirmation times of less than 50 milliseconds. The goal is to deliver an execution experience close to that of centralized exchanges (CEX) while retaining the advantages of on-chain self-custody and transparency.In terms of technical architecture, the new chain will remove the traditional public mempool and introduce a transaction transmission mechanism called "TxStream," which directly sends transactions to block producers to reduce latency and minimize MEV extraction behaviors such as sandwich attacks.

: The Zcash Foundation has released version 4.5.0 of its node client, Zebra. This update includes multiple security fixes, addressing a critical consensus vulnerability and several high-severity Denial of Service (DoS) issues. All node operators are strongly urged to upgrade immediately.Key fixes in this release include a sigop counting error in P2SH script parsing (which could cause a consensus fork with zcashd), a logic flaw in NU5 block validation caching, a crash risk related to transparent address balance overflow, along with multiple crash and resource exhaustion vulnerabilities in RPC interfaces and mempool processing. The Foundation stated that some vulnerabilities could be exploited by malicious nodes, leading to node stalls, restart loops, or even permanent stoppage.Additionally, this version adds support for ZIP-213 (enabling shielded coinbase outputs to Sapling) and optimizes network performance and security boundaries. This includes limiting resource allocation during the pre-handshake phase, fixing risks related to multi-threaded queue abuse, and enhancing the misbehavior scoring mechanism.The Zcash Foundation stated that this update addresses over 80 security reports from the ZCG Vulnerability Disclosure Program (spanning April to May 2026), covering multiple layers including consensus security, memory management, RPC processing, and the P2P network attack surface. Officials emphasized that there is no alternative to this upgrade; upgrading is the only way to ensure nodes do not experience a chain split and remain secure.
