Quick Take
- Scalability is hard for decentralized blockchains because numerous confirmations by a large network of nodes are both computationally intensive and time-consuming
- Per the scalability trilemma, blockchains that keep to “simple” techniques almost inevitably have to sacrifice either decentralization or security to preserve scalability
- Here, we dive into advanced techniques at the data layer, including block expansions, segregated witness (SegWit), and directed acyclic graphs (DAGs) that try to increase scalability while preserving decentralization and security
- We also cover “Layer 0” scaling strategies that try to accelerate block propagation by improving the communication protocol for any blockchain network
