Blockchain Trilemma & Rollups

Last week, we briefly mentioned #Ethereum and its Danksharding method for on-chain scalability. However, there are other methods aimed at addressing the blockchain trilemma, which refers to the unavoidable trade-offs between:

Scalability
Decentralisation
Security

This cryptographic problem has not been solved yet; however, several scalability solutions have been proposed in the literature, such as traditional Sharding, Lightning Network, increasing block sizes, and Rollups.

Rollups takes advantage of the concept that all core blockchain tasks, including consensus settlement, data availability guarantee, and transaction execution, must not be performed on a single layer. Some modular blockchains , such as Syscoin, perform one of these core tasks on a different layer. Rollups are an off-chain technique that can convert a single chain into a modular framework by processing transactions outside the primary chain. This approach preserves the main chain's state while applying the most recently processed state on the other chain (i.e., layer 2).

Other off-chain scalability methods exist besides Rollups like Plasma and Sidechains, but over this week, we will discuss the increasingly popular Rollups, their benefits and much more!

Stay tuned!
