Solana is a project dedicated to supporting large and high-frequency blockchain applications, another goal is to democratize financial systems. How does Solana wants to achieve this? Solana is a delegated Proof of Stake protocol with a focus on scalability, without the loss of decentralization or security. Achieving scalability, decentralization and security is considered the holy grail when it comes to distributed ledger technologies. The solution Solana offers lays within its decentralized clock, called the Proof-of-History (PoH). The PoH allows each node to locally generate timestamps, eliminating the need for broadcasting these across the network. This results in a more efficient network.
