ALPENGLOW APPROVED BY SOLANA COMMUNITY: The Solana group voted overwhelmingly in favor of the long-awaited Alpenglow improve, bringing the community one step nearer to probably the most vital technical transformation in its historical past. In line with Solana Standing on X, 98.27% of SOL stakers that voted accredited the proposal, with just one.05% voting towards and 0.36% abstaining. In whole, 52% of the community’s stakers participated within the vote. The improve introduces a brand new consensus protocol designed to dramatically enhance transaction finality and community effectivity. On the coronary heart of Alpenglow are two new elements, Votor and Rotor, which can change Solana’s present programs, Proof-of-Historical past and TowerBFT. Presently, Proof-of-Historical past timestamps transactions to protect their order with out slowing the community, whereas TowerBFT handles the voting course of amongst validators. Alpenglow will overhaul each programs. Votor will slash transaction finality instances from over 12 seconds to round 150 milliseconds, delivering near-instant affirmation for customers. Rotor, scheduled for a later rollout, will decrease knowledge transfers between validators, an important enchancment for high-demand functions reminiscent of decentralized finance (DeFi) and blockchain-based gaming.With approval secured, Solana is now getting ready to implement the improve, a milestone anticipated to unlock better velocity, resilience, and scalability throughout its ecosystem. — Margaux Nijkerk Learn extra.
EF TO SELL 10K ETH OVER NEXT FEW WEEKS: The Ethereum Basis (EF) shared in a submit on X on Tuesday that it plans to promote 10,000 ETH by centralized exchanges over the following a number of weeks to assist work towards analysis & growth, ecosystem grants and associated donations. In line with CoinMarketCap, the ETH will quantity to roughly $43 million at Tuesday’s costs. “Conversions will happen over a number of smaller orders, reasonably than as a single giant transaction,” the EF wrote within the submit on X.The information follows the EF’s rollout of a brand new treasury coverage in June that caps annual operational spending (opex) at 15%, establishes a multiyear reserve buffer and units a gradual tempo towards even leaner spending long-term. The inspiration offered a further 10,000 ETH to SharpLink Gaming in July, making the web on line casino advertising and marketing agency the primary publicly traded firm to purchase ETH from a key agency within the community’s ecosystem. — Margaux Nijkerk Learn extra.
A CHAT WITH BRUCE LIU ON OP_CAT: With out OP_CAT, Bruce Liu says Bitcoin is as “helpful as a jumbo jet with out wings” able to way more than it’s allowed to do, however caught on the bottom whereas Ethereum and Solana soar. Liu, the founding father of OPCAT_Labs, says a single opcode, OP_CAT, might remodel bitcoin from static digital gold into programmable cash that rivals different layer-1 chains. OP_CAT is a long-disabled opcode in Bitcoin’s code that, if re-enabled, would enable builders to concatenate knowledge in scripts and unlock new potentialities, from vaults and covenants to decentralized exchanges and zero-knowledge proofs. The Bitcoin blockchain, if OP_CAT was re-enabled, can be as programmable as Ethereum or Solana, mentioned Liu. “OP_CAT is just not new code. It was by no means deleted, simply commented out and disabled. We aren’t including my opcode or someone else’s. It’s Satoshi’s,” Liu informed CoinDesk throughout an interview on the sidelines of BTC Asia in Hong Kong. — Sam Reynolds Learn extra.
HOLESKY SUNSET IS COMING AFTER FUSAKA UPGRADE: A recent slate of Ethereum testnets is changing Holesky, the once-massive staging floor now set for shutdown after two years of service.The wind-down will happen two weeks after the Fusaka improve is finalized later this 12 months, at which level consumer and infrastructure groups will stop offering assist. Fusaka is about to make Ethereum rollups cheaper and sooner by spreading out the “knowledge storage work” extra evenly throughout validators. Holesky went reside in 2023 to stress-test Ethereum’s proof-of-stake equipment at scale. It shortly turned the most important public testnet, offering 1000’s of validators with a platform to trial upgrades earlier than they had been deployed on the mainnet. Main milestones, such because the Dencun and Pectra upgrades — which lowered transaction prices and upgraded validator effectivity, amongst different options — had been run by Holesky first. Nevertheless, cracks started to appear because the community aged. Holesky encountered “inactivity leaks” after Pectra’s activation in early 2025, a time period referring to validators going offline in giant numbers, which created a big backlog for these trying to exit. The consequence was months-long queues that made it impractical to check the total validator lifecycle. For builders needing quick suggestions loops, Holesky had turn out to be extra of a roadblock than a software. — Shaurya Malwa Learn extra.
