Solana describes itself as a third-generation network designed to solve the blockchain trilemma — the almost impossible feat of improving performance without compromising decentralization and security. Solana looks to succeed where first and second-generation blockchains have failed by introducing innovative methodologies to optimize a blockchain network's speed while retaining a high level of decentralization. Solana's decision to focus on finding a balance between speed, security, and decentralization stems from the need to create enabling environments for launching world-class decentralized applications. The goal is to provide a blockchain network to help DApps attain the same functionality and user experience that their centralized counterparts offer. The Solana ecosystem has SOL as its base currency, which users can use to make payments, settle related fees and participate in the network's staking economy. The digital asset also doubles as Solana's governance currency. In essence, SOL holders can vote on proposals that would, in turn, determine the type of changes and upgrades adopted by the Solana ecosystem.
