Is Solana PoS or DPoS?

Solana uses a PoS not a DPoS consensus mechanism , as discussed many times. It’s an easy mistake to make because there are multiple roles on the Solana blockchain (leaders, validators, archivers, etc.). While DPoS cryptocurrencies essentially delegate these roles among network participants, Solana does not.

Solana can process many more transactions per second and charges much lower transaction fees than rival blockchains like Ethereum. Solana is a proof-of-stake (PoS) blockchain and also uses a new technology called Proof of History (PoH).1 Ara 2021

Solana uses proof-of-stake as well as a protocol known as proof-of-history. How many transactions can Solana do per second? Solana has a theoretical throughput of 65,000.
