AltLayer is a system of highly scalable application-dedicated execution layers that derive security from an underlying L1/L2. It is designed as a modular and pluggable framework for a multi-chain and multi-VM world. At its core, AltLayer is a system of several optimistic rollup-like execution layers called flash layers with a novel innovation that makes them disposable and therefore highly resource-optimized.
Manta is the universal private blockchain platform provides end-to-end privacy protection for blockchain users through leading cryptography architectures such as zkSNARK.
