Solana (SOL) price enters April 2026 under pressure, with March closing at roughly -0.88%, extending a red streak that now stretches six consecutive months since October 2025, with a head-and-shoulders breakdown on the daily chart confirmed on March 27 opening a measured move target near $73. Solana plans a major consensus upgrade with the new Alpenglow protocol developed by Anza, which would replace Solana's current Proof of History and Tower BFT systems, introducing Votor (which can finalize blocks in 100 to 150 milliseconds) and Rotor (a more efficient data relay protocol), with the upgrade expected to make transactions faster and possibly increase demand for the SOL token. SOL trades around $86 at press time, with analysts suggesting that if the spot price stabilizes above $85, a rebound toward the $88–$90 resistance zone is plausible.
