Most blockchains have transactions limits baked into the protocol (e.g. adding more servers to Bitcoin does not increase its transaction volume) and need cumbersome workarounds to address scaling. The Internet Computer can process unbounded volumes of smart contract data and computation natively because it can grow in capacity by adding more nodes. That is how the network went from 19 blocks per second in July 2021 to 30 blocks per second by December 2021.
