Foresight News reported that the core development team of Solana, Anza, posted on Twitter announcing that Agave 4.0 has officially been pushed for upgrade to mainnet validators. This version brings multiple performance improvements, including significantly reduced network transmission latency, unified transaction submission using the QUIC protocol, and several on-chain modifications that unlock more block capacity, laying the foundation for Solana to pursue higher throughput.Main updates include: after introducing XDP technology, Turbine retransmission latency dropped from 600ms to approximately 0.8ms, establishing the basis for advancing 100 million compute unit blocks; transaction submissions now exclusively support QUIC, removing UDP entry points; replay phase speeds have been improved through asynchronous optimization; vote transactions no longer use the static CU cost model, releasing more block capacity. Additionally, various features will be activated during this version cycle, including p-token (releasing about 13% of block capacity), Stake Program v5 (minimum staking threshold increased from 1 lamport to 1 SOL), SBPFv3 program support, and BLS12-381 system calls.

The effective federal funds rate for the previous trading day was reported at 3.63%, remaining unchanged from the day before at 3.63%.

```htmlGolden Ten Data reported on May 18 that high mortgage rates, rising oil prices, and persistent economic uncertainty caused by the ongoing war with Iran continue to put pressure on potential homebuyers. However, U.S. builders are seeing a slight improvement in their business conditions and expect a surge in growth towards the end of spring. After a significant drop in April, the Housing Market Index released by the National Association of Home Builders (NAHB) showed that the builder confidence index for single-family homes rose by 3 points in May, reaching 37. Nevertheless, any reading below 50 is considered indicative of market pessimism. Robert Dietz, the association’s chief economist, said: "The recent rise in long-term interest rates will continue to suppress housing demand. Despite relatively strong market performance in certain regions, including parts of the Midwest, the housing market is still facing severe affordability challenges."```
