Anza

Anza has just announced Alpenglow – the largest upgrade in Solana's history, aiming to reduce latency to 150 milliseconds, bringing this blockchain to response speeds comparable to Web2. Could this be the turning point for Solana to overcome its weaknesses and lead the race?

Alpenglow: The Largest Core Change in Solana

In the whitepaper dated 05/20/2025, the research team #Anza – including Quentin Kniep, Kobi Sliwinski, and Roger Wattenhofer – describes Alpenglow as a 'turning point' for Solana. This upgrade changes the core protocol, with two main components: Votor (consensus) and Rotor (data distribution), aimed at increasing speed and efficiency.

The #Solana Foundation recently patched a serious flaw in its privacy-focused Token-22 system that could have allowed attackers to forge fake zero-knowledge proofs (ZKPs). This bug could have enabled unauthorized minting of tokens or withdrawal from other accounts.
Reported on April 16 via ’s GitHub, the vulnerability involved missing algebraic components in the ElGamal Proof program, a part of s confidential transfer mechanism. This flaw meant invalid proofs could be wrongly accepted by the #blockchain .
Development teams from #Anza , Firedancer, and Jito verified and swiftly fixed the issue. Patches were quietly rolled out to validators starting April 17, with further updates issued later that day. Third-party firms, including Asymmetric Research, Neodyme, and OtterSec, reviewed the fixes.
The main #SPL tokens and Token-2022 logic were unaffected. No exploits have been detected, and all funds remain safe.
