Mosaic is a parallelisation schema for decentralized applications. It introduces a set of Byzantine fault-tolerant consensus rules to compose heterogeneous blockchain systems into one another.
Decentralized applications can use Mosaic to compute over a composed network of multiple blockchain systems in parallel.
Use this category for anything that relates to the OpenST Mosaic protocol. Including, but not limited to, smart contract and validator node implementations.
If you want to discuss how to use Mosaic in a dApp, you should instead check out the category OpenST.
