Blockchain is a radical new technology. It has the potential to profoundly disrupt a wide range of industries including finance, healthcare, logistics, and public administration. Despite its great potential, today's blockchain has several major hurdles to overcome in order to see widespread adoption. First, it can slow. Second, it can be costly. Third, it has scalability issues. For example, Dapper Labs (Axiom Zen's blockchain subsidiary) launched CryptoKitties - the world's first Ethereum game - in late 2017, soon creating network congestion for all users of the Ethereum blockchain. Motivated by this, we aim to develop a theoretical framework together with Dapper Labs that allows us to compare and evaluate various solutions that address the major hurdles facing today's blockchain.
