On May 18, Solana development firm Anza announced a formal recommendation for mainnet validators to upgrade to Agave 4.0. This update brings key improvements: XDP support for Turbine, QUIC-only TPU data access, a faster replay stage, and multiple SIMD features that will roll out in this cycle. Anza noted that production testing with large mainnet validators found XDP cut Turbine retransmit latency from about 600ms to roughly 0.8ms, giving Solana critical performance breathing room to scale to 1 billion compute units (CUs) per block. Additionally, Agave 4.0 completely removes UDP transaction access, making QUIC the sole transaction submission method. The update also shifts PoH entry validation and Ed25519 signature verification off the critical path, processing those tasks asynchronously to boost replay stage performance. This upgrade will also gradually roll out several SIMD features, including p-token—an SPL Token alternative that frees up approximately 13% of block capacity—Stake

Analysts note that since U.S.-Iran tensions escalated, global oil prices have stayed above $100 per barrel, and potential long-term disruptions to the Strait of Hormuz are amplifying concerns over a new round of inflation. Capital Economics has warned the market has not fully priced in the extreme scenario of a prolonged Strait of Hormuz blockade. Despite the AI investment frenzy and strong corporate earnings propping up U.S. stock performance, some institutions believe the S&P 500’s forward P/E ratio has risen to 21.3—well above its long-term average. With the bond market leading the charge in repricing inflation, stocks could face dual pres

On May 18, Hyperliquid’s HYPE token is forming a classic bullish cup-and-handle chart pattern. Analysts believe a breakout above the key resistance level of $45–$47 could push the token’s price to the $71–$72 range—representing roughly a 55% upside from current levels and hitting a new all-time high. On-chain data shows wallet addresses linked to a16z have accumulated approximately 2.11 million HYPE tokens over the past month, totaling about $90.87 million. The most recent transaction included an additional purchase of 372,000 HYPE tokens within just 3 hours, worth around $16.91 million. Market analysts note that sustained institutional accumulation, combined with the recent launch of a U.S. HYPE spot ETF, infrastructure support from Coinbase and Circle for Hyperliquid via USDC, and potential regulatory optimism tied to the U.S. CLARITY Act, are boosting market expectations for Hyperliquid’s long-term growth.
