Solana
According to Investopedia:
“Solana is a high-performance blockchain designed to facilitate decentralized apps (dApps) and smart contracts on a massive scale.” Its native cryptocurrency, SOL, is used for transactions, staking, and governance within the Solana ecosystem.
Solana attempts to improve on the scalability issues inherent in proof of stake and proof of work by introducing something called proof of history (PoH).
POH is a procedure that makes transactions faster by centralising time.
The high throughput and corresponding low fees has seen Solana attract widespread attention and explode in popularity.
It now boasts hundreds of Dapps on its platform and, most notably, has become one of the most important platforms for NFTs.
