Maybe we can layer them like a sandwich? Platforms like Bitcoin and Ethereum are known as ‘Proof of Work’ blockchains, where the ‘work’ required to add that transaction to the blockchain uses a large amount of computing time and energy. The time in between blocks is not what determines throughput in crypto networks.
