New Solana Consensus Model ‘Alpenglow’ Enters Community Vote
Solana core developers have pushed a sweeping consensus overhaul, “Alpenglow” (SIMD-0326), into the ecosystem’s formal governance track, setting up a validator vote that, if approved, would replace TowerBFT and re-architect finality and validator incentives on mainnet-beta. The proposal’s authors—Quentin Kniep, Kobi Sliwinski, and Roger Wattenhofer—describe Alpenglow as “a major overhaul of Solana’s core consensus protocol,” […]

When discussing consensus mechanisms for different cryptocurrencies, one issue that often causes arguments is a lack of understanding (and definition) of the security model that they provide for the historical data in the ledger. While each consensus model aims to prevent various theoretical attacks, it’s important to understand the goals for the model. Every security model has two main parts: assumptions and guarantees. If the assumptions used as inputs hold true, then so should the guarantees that are output by the model. Let’s dig into the security model that appears to be offered to....
