Solana is a highly functional open source project that banks on blockchain technology's permissionless nature to provide decentralized finance (DeFi) solutions. While the idea and initial work on the project began in 2017, Solana was officially launched in March 2020 by the Solana Foundation with headquarters in Geneva, Switzerland.
The Solana protocol is designed to facilitate decentralized app (DApp) creation. Itaims to improve scalability by introducing a proof-of-history (PoH) consensus combined with the underlying proof-of-stake (PoS) consensus of the blockchain.
Proof-of-History is a time-based consensus mechanism that develops a historical record of an activity based on its position in the blockchain, which is represented by a hash tree. This lets any node quickly verify the order of all transactions by checking the hashes on the hash tree, allowing for fast and efficient validation without requiring the nodes to store the full history of every transaction.
Anatoly Yakovenko, Solana's main founder, created the first version of Proof-of-History (PoH) in 2017. Teaming up with Raj Gokal, Greg Fitzgerald, and Stephen Akridge, they worked on building a high-performance blockchain that would solve scalability issues faced by popular blockchains like Ethereum, which often became slow and expensive at times of high demand. Solana Labs was launched in 2018 to support these efforts, and Solana was officially launched in 2020.
Because of the innovative hybrid consensus model, Solana enjoys interest from small-time traders and institutional traders alike. A significant focus for the Solana Foundation is to make decentralized finance accessible on a larger scale.
Solana is a cryptocurrency currently trading at $83.77 with a market capitalization of $48.12B as of April 30, 2026. You can manage Solana directly in Trust Wallet.
