Recent developments suggest the network is working to become a high-performance settlement layer and a more resilient base for large-scale financial activity.
One of the strongest adoption signals came from Visa, where Head of Crypto Cuy Sheffield confirmed that two U.S. banks have begun settling transactions in USDC on the Solana network.
Sheffield noted that Visa is excited to build on its existing momentum in stablecoins. Stablecoin settlement at this level highlights confidence in Solana’s throughput, cost efficiency, and reliability.
In other news, Solana developers are preparing a major consensus overhaul through SIMD 0326, which introduces the Alpenglow consensus protocol.
 
Alpenglow replaces Proof of History and TowerBFT with a streamlined architecture centered on direct voting and faster finality.
Under the new design, block finalization latency could drop from roughly 12.8 seconds to as low as 100-150 milliseconds, bringing performance closer to Web2 standards.
The protocol also improves bandwidth efficiency by eliminating heavy gossip traffic and introducing aggregated cryptographic proofs for consensus.
Alpenglow is designed to address long-standing performance and security limitations. It strengthens fault tolerance through a “20 plus 20” resilience model, allowing the network to remain live even if a significant portion of validators are adversarial or offline.
The overhaul has also reworked incentive structures, replacing on-chain vote transactions with off-chain voting and introducing a Validator Admission Ticket to preserve economic fairness.
A December 2025 testnet launch is in the works, with mainnet activation targeted for 2026.
Looking ahead, Solana’s outlook is cautiously optimistic. Continued technical innovation, improved stability, and rising developer activity could cement its position across DeFi, NFTs, and consumer applications.
Under favorable conditions, some projections place Solana’s 2026 price range between $200 and $500 or higher, reflecting both opportunity and execution risk.
