BNB Chain Launches New Layer 1 for Agent Trading, Targeting 2027 Mainnet Launch
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 plans to launch a new Layer 1 blockchain, with mainnet expected to go live in 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.

Zcash Foundation Urgently Releases Zebra 4.5.0: Critical Consensus Bug Fix and Mandatory Upgrade Recommended
: 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.
Foundry USA mined 6 consecutive blocks, Bitcoin block 941,881 chain reorganization completed
Odaily News, March 24 – Antpool mined Bitcoin block 941,881 at UTC time 15:49:35. Foundry USA mined another version of the same height 12 seconds later, briefly creating two competing chains on the Bitcoin blockchain. Subsequently, ViaBTC extended block 941,882 on top of the Antpool version, while Foundry USA also continued to extend its own branch. Foundry USA then mined blocks 941,883 to 941,886 consecutively, giving its branch a cumulative workload lead. Nodes subsequently reorganized to the Foundry USA version, causing the blocks mined by Antpool and ViaBTC to become orphaned. The affected miners lost the corresponding block rewards and fees, and transactions not confirmed on the winning chain re-entered the mempool to be confirmed in subsequent blocks.

Ethereum Foundation’s Kohaku Launches Wallet Privacy Integration SDK, Enabling Ethereum Wallets to Integrate Protocols Such as Railgun
According to The Defiant, the Ethereum Foundation’s Kohaku Initiative has released an SDK for integrating privacy protocols into Ethereum wallets. A functional 4337 mempool relay supporting private transactions is now available in version v0.0.1-alpha.21 of the kohaku-eth/railgun integration. This SDK aims to integrate shielded-pool protocols—such as Railgun, Tornado Cash, and Privacy Pools—directly into wallet interfaces, reducing reliance on centralized relay infrastructure. Kohaku has also demonstrated a CLI-based wallet and is advancing integration with production-grade wallets like Ambire, while simultaneously developing post-quantum accounts, multisig support, and hardware wallet compatibility.

Deloitte Effectively Acquires Blocknative Team, Company to Discontinue API and Gas Network Services
Deloitte has absorbed the crypto infrastructure company Blocknative through a "team acquisition." The Blocknative team will now focus on driving Web3 innovation within Deloitte's client portfolio.According to an announcement on Blocknative's official website, the company is ceasing operations. Its API services and Gas Network are expected to run until June 19 before being gradually shut down. Founded in 2018, Blocknative primarily provided real-time mempool monitoring, Gas fee forecasting, and transaction management tools. Its Gas Network was used to deliver real-time Gas price data.This transaction occurs against the backdrop of a new wave of consolidation in the crypto industry. Recently, multiple infrastructure projects have experienced layoffs or ceased operations, while traditional professional services firms like Deloitte continue to expand their service coverage in the crypto sector, including accounting, auditing, and corporate advisory.
