💎Solana is an open infrastructure for building scalable crypto applications. Its architecture is censorship-resistant, fast, and secure, and it is designed to facilitate global adoption. To maintain time on the Solana blockchain, it employs an innovative process called Proof of History. PoH is not a consensus mechanism, but it plays an important role in Solana's Proof of Stake consensus mechanism.
The result of PoH and another key innovation of Solana makes the network highly scalable; in fact, Solana can process a maximum of 50,000 transactions per second. The blockchain remains cheap and fast as it scales, with an average transaction fee of $0.00025 and block time typically below one second, with finality in less than a second.
Solana also maintains composability among ecosystem projects through its unique global state, meaning that it is not necessary to integrate it with multiple shards or 2-layer solutions. Other benefits of building on Solana include auditing, enterprise-level security, and the flexibility to code in popular languages such as C, C++, and Rust.
