Alpenglow is a proposed new consensus mechanism for the Solana blockchain, aimed at improving its efficiency and scalability. The mechanism leverages a hybrid approach, combining elements from both proof-of-stake and proof-of-history to enhance transaction throughput and reduce latency. By addressing existing limitations, Alpenglow seeks to position Solana as a leading platform for decentralized applications and services.

Jump Crypto's Firedancer team suggests lifting the compute limit on Solana blocks after the Alpenglow upgrade, enabling scalability based on validator performance. This change aims to incentivize hardware improvements among validators, fostering a competitive environment for transaction capacity. Concerns about potential centralization and network stability have been raised by industry experts.
