Solana a public Blockchain Platform. It uses the Proof of Stake (PoS) mechanism as its Consensus Process. Its internal cryptocurrency is SOL.

In 2021, Bloomberg journalist Joanna Ossinger described Solana as “a potential long-term rival for Ethereum”, citing superior Transaction speeds and lower associated costs.

On 14 September 2021, the Solana blockchain went offline after a surge of transactions caused the network to Fork, and different validators had different views on the state of the network. The network was shortly brought back online on 15 September 2021. Solana can purportedly handle 50,000 transactions per second, which is faster than the Ethereum blockchain, but still less than the 400,000 transactions seen during the spike.

Like various other blockchains, Solana can run Smart Contracts.
