ZK-Rollups and The Race to Becoming The Premier L2 Execution Layer

Scalability Trilemma

Scalability: the chain can process more transactions than a single regular node (think: a consumer laptop) can verify.

Decentralization: the chain can run without any trust dependencies on a small group of large centralized actors. This is typically interpreted to mean that there should not be any trust (or even honest-majority assumption) of a set of nodes that you cannot join with just a consumer laptop.

Security: the chain can resist a large percentage of participating nodes trying to attack it (ideally 50%; anything above 25% is fine, 5% is definitely not fine).
