Solana is one of those emerging blockchains that have capitalized on Ethereum’s issues. Known as the “Ethereum killer” by some observers, Solana calls itself the “fastest blockchain in the world,” boasting 1,547 transactions per second (TPS). By way of comparison, the Ethereum blockchain is much slower, at about 15 TPS, but with the upgrade to Eth 2.0, that will jump to up to 100,000 TPS.
