• Sharding is the process of splitting a database.
• Generally speaking, transactions are submitted to these layer 2 nodes instead of being submitted
• Sharding was on the Ethereum roadmap for a long time, and was once intended to be shipped before The Merge to proof-of-stake. However, the rapid development of layer 2 rollups and the invention of Danksharding (adding blobs of rollup data to Ethereum blocks that can be very efficiently verified by validators) has led the Ethereum community to favou...
• Layer 2 is a collective term for solutions designed to help scale your application by handling transactions off the Ethereum Mainnet (layer 1) while taking advantage of the robust decentralized security model of Mainnet.
• There are application-specific layer 2 networks that bring their own set of efficiencies when working with assets at scale.
