In brief Ethereum Foundation researchers have published a draft “strawmap” outlining seven Ethereum forks through 2029, projecting roughly one upgrade every six months. The roadmap targets shorter slot times and finality measured in seconds through a shift from Gasper to a one-round BFT

Solana plans to launch the Alpenglow consensus upgrade in 2026, replacing the existing Tower BFT and PoH mechanisms. The new architecture achieves finality times of 100 to 150 milliseconds, approximately 100 times faster than the original 12.8 seconds. Core components include Votor voting aggregation and Rotor block propagation optimization, with latency reduced to as low as 18 milliseconds.

Cardano self-healed after a minority chain formed, removing the bugged transaction without losing most history or progress. BFT-style blockchains like Solana could face permanent issues in similar cases due to strict 67% consensus rules. Gradual stake growth on minority forks allows

The core upgrade proposal "Alpenglow" (SIMD-0326) for the Solana Blockchain has officially entered the community voting stage. This proposal aims to discard the existing Proof of History (PoH) and Tower BFT mechanisms, reducing the block finalization time from 12.8 seconds to 150 milliseconds. As a result, the price of SOL has surpassed $211, with an intraday rise of 3.78% and a trading volume surge of 43%. The retail investor sentiment ratio has reached an 11-week high. This article provides an in-depth analysis of the technical value of the Alpenglow upgrade, the voting progress, and its long-term impact on the SOL ecosystem.
