Solana Developers Propose Major Upgrade with New Consensus Protocol Alpenglow

Solana developers are planning a major core upgrade called Alpenglow, aimed at enhancing the blockchain's consensus mechanism for faster finality and responsiveness.

Key details include:

  • Alpenglow will replace Proof of History and Tower BFT, addressing their complexities and slowness.
  • The new solution consists of two parts: Votor, which can finalize transactions in 100–150 milliseconds, and Rotor, a more efficient data relay protocol.
  • This upgrade targets improved developer experience and supports applications such as real-time finance and gaming.
  • Finality under one second could significantly enhance on-chain activity and demand for SOL tokens.
  • Votor can finalize blocks in one voting round with 80% stake online or two rounds with 60% responsive, optimizing transaction confirmations.

No launch date is confirmed yet. If successful, Alpenglow could solidify Solana's reputation as a leading Layer 1 blockchain for real-time applications.
