Pi Network rolls out a security update, requiring Pioneers to enable two-factor authentication (2FA) to protect users’ account and wallet security and prevent loss of funds during the mainnet migration. This move addresses ongoing scam threats and ensures that sensitive actions are approved only by the account owner. At the same time, node operators have upgraded to protocol 21.2 to improve system performance. Users must complete the mainnet migration step by step to safeguard their assets.

Ampersend went live on April 3 to provide AI Agents with an independent wallet and budget controls. Users can register via the official website or add a Skill for OpenClaw. The product supports multiple open standards and is developed by the Edge & Node team.

At the EthCC conference, an AWS researcher conducted high-pressure testing on the Ethereum Verkle tree, revealing four major performance bottlenecks facing statelessness and proposing optimization solutions, which are expected to improve node operating efficiency by more than 3x.

An Ethereum Foundation researcher presented the zkAttester client solution at the EthCC conference, addressing the computational burden of node re-execution, allowing validators to verify zero-knowledge proofs directly, lowering CPU performance requirements, shortening the time for new node synchronization, and helping enable Ethereum light verification and scaling.

Ethereum Foundation researcher CPerezz introduced the VOPS technology at the EthCC conference, aiming to solve Ethereum’s state bloat problem and reduce the storage requirements for full nodes. VOPS nodes only need to store basic fields, reducing storage requirements by 25x, enabling users to participate in transactions, and accelerating Ethereum’s move toward statelessness.

Pi Network announced a phased plan to upgrade nodes to v23. Version 21.2 will be deployed in April 2026, with future versions supporting smart contracts and enhancing node tools and autonomy. Market feedback is cautiously optimistic, but past delays have kept users on hold. The next few months will be a critical window.

Google announced a quantum cryptography migration timetable in March 2026, planning to complete system upgrades by 2029 to address quantum computing threats. The focus is on transitioning authentication systems to post-quantum cryptography and updating products like Android and Chrome accordingly. This development is significant for the blockchain industry, as future encryption security will face new challenges.

On March 23rd, Cardano (ADA) faced selling pressure, with prices retreating to $0.25, affected by the US-Iran conflict as market risk assets were liquidated. Futures contracts show shorts dominating, with technical indicators suggesting a breakdown below $0.22 could accelerate the downtrend. However, analysts identified buy signals, with ADA potentially maintaining above $0.23 potentially driving price increases. Meanwhile, the development team released Node 10.7.0, laying the groundwork for future upgrades, and Midnight privacy sidechain launching this week could bring growth potential.

Gate News: On March 19, Monad co-founder Keone Hon posted on Twitter stating that Monad mainnet will undergo a hard fork today at 22:30 Beijing time to upgrade to the MONAD_NINE version. This upgrade introduces three improvement proposals: MIP-3, MIP-4, and MIP-5. Before the hard fork, node operators need to upgrade to at least

On March 18th, Moody's launched the Token Integration Engine (TIE), becoming the first rating agency to bring analytical capabilities to blockchain, aimed at directly acquiring and distributing on-chain financial data. The first node is Canton Network, with plans to expand to more blockchain networks in the future.
