Solana’s ‘Alpenglow’ Upgrade Live for Testing



Network News

LIVE “ALPENGLOW” UPGRADES FOR TESTING ON SOLANA: Solana developer Anza said Alpenglow, the largest network proposal for revision of the consensus to date, is live on a community testing cluster, marking a major step towards a potential mainnet deployment. The update means that validation operators can now test software designed to transition Solana from its current consensus system, which combines Proof-of-Stake with TowerBFT and Proof-of-History, to a new architecture intended to significantly reduce time-to-finality and improve network responsiveness. “Alpenglow is live on the community testing cluster”, Anza written the. “The biggest consensus change in Solana history, now running on validator infrastructure before mainnet.” Today, Solana leverages Proof-of-History, a cryptographic clock that timestamps transactions, alongside TowerBFT, a voting mechanism that validators use to agree on the state of the blockchain. Although the design helped Solana achieve high throughput and low fees, some have pointed to outages and network instability during periods of high demand. — Margaux Nijkerk Learn more.

LAYERZERO APOLOGY FOR KELP DAO INCIDENT: LayerZero said that it “made a mistake” by allowing its own verification infrastructure to secure high-value crypto assets in a vulnerable setup, marking a notable change in tone after weeks of blame on the developer Kelp DAO for $292 million hack linked to North Korean attackers. This admission marks a notable change after weeks of public finger pointing between LayerZero and Kelp on responsibility for the April hack, which LayerZero initially presented as an application-level configuration failure by Kelp. “First of all: a long overdue apology,” LayerZero wrote in a blog. LayerZero initially blamed Kelp, arguing that the protocol chose a risky “1 on 1” setup in which a single decentralized verification network, or DVN, had to approve cross-chain transfers, creating a single point of failure. A DVN is part of the infrastructure that verifies whether a transaction transferring assets between blockchains is legitimate. “We made a mistake in allowing our DVN to act as a 1/1 DVN for high-value transactions,” the company said. “We didn’t control what our DVN was securing, which created a risk that we simply didn’t see. We own it.” — Sam Reynolds Learn more.

RONIN TRANSITING TO LAYER-2: Ronin, the gaming-centric blockchain once synonymous with the industry infamous $625 million feat in 2022, officially loses its sidechain skin on May 12 to become an Ethereum 2 layer to improve security while maintaining throughput. Ronin, which announced the migration in April, will perform a hard fork at block 55,577,490, a process that will result in approximately 10 hours of downtime for users, according to the network said Monday. According to chain dataThe migration is expected to begin Tuesday around 3:16 p.m. UTC. “Four years ago, we launched Ronin because Axie Infinity needed a faster, more efficient network,” Ronin said when announcing the migration. “It worked. Axie Infinity brought millions of players to crypto, and Pixels proved it was possible to do it again.” Now is the time to “reconnect with the mothership.” While operating as an independent sidechain in mid-May 2022, Ronin underwent what is still today the largest DeFI bridge feat in history. Layer 2 protocols benefit closer ties to the underlying blockchain than sidechains, offering benefits that include greater security. — Olivier Acuna Learn more.

ETHEREUM DEVELOPERS RELEASE “A CLEAR SIGNATURE”: The Ethereum Foundation and a group of leading crypto wallet developers deploy a new security standard designed to prevent users from accidentally giving up their funds, a problem that has fueled some of the industry’s biggest hacks and scams. The initiative, called “Clear Signing”, aims to replace confusing walls of code users currently see when they approve Ethereum transactions with simple, human-readable explanations of what they are actually accepting. This effort comes after years of phishing attacks and wallet leaks that often boil down to the same problem: users unknowingly approve malicious transactions they don’t understand. The Ethereum Foundation cited incidents such as the Bybit hack as examples of how attackers exploit “blind signing,” where users approve transactions filled with unreadable technical data. Right now, signing a crypto transaction can feel like clicking “accept” on a terms of service page written in another language. Wallets often display long strings of code that only highly technical users can decipher, leaving ordinary traders vulnerable to fake apps, malicious links, and compromised websites. — Margaux Nijkerk Learn more.

The latest version isn’t expected to offer many surprises to the crypto industry that has already had a chance to review it privately, but it does include still-controversial language on stablecoin yield and maintains legal protections for decentralized finance (DeFi) developers, keeping this corner of the crypto sector happy (so far). Industry insiders waited late into the night for the release, and they’ll have to do it again study the language to ensure their expectations are met. “This bill reflects serious, good faith work in the committee and provides the certainty, safeguards, and accountability that Americans deserve,” committee Chairman Tim Scott said in a statement. “It puts consumers first, fights illicit finance, cracks down on criminals and foreign adversaries, and safeguards the future of finance here in the United States.” — Jesse Hamilton Learn more.
