Polkadot (DOT) vs Solana (SOL)

Polkadot is a distributed and programmable "layer 0" blockchain, designed as a technological foundation for building various specialized blockchains dedicated to one or more use cases, interconnected with each other and called "parachains."

Solana is a distributed and programmable layer 1 blockchain, part of the trend of "Ethereum Killers," which are competitors of Ethereum looking to replace it. Solana's unique design (notably through the Proof of History consensus) allows it to be optimized for scalability, with an exceptional (and theoretical) execution capacity of 60,000 transactions per second and extremely low fees. SOL is the native cryptocurrency of the Solana network, used to pay transaction fees, reward validators, and contribute to the governance of the project.
