Cellframe is a service oriented blockchain platform. Many different services could be build on Cellframe e.g. another blockchain, VPN, streaming services and many other products. This means that Cellframe could be used for every Layer. It’s a white usage SDK. Layer zero (Network Category Layer) is interoperability usage: peer-to-peer mesh network. Layer one (Fundamental Layer) is basic usage. The cryptographic protocols: ChaCha20 (SALSA2012), MSrln & SIDH, Keccak, CRYSTALS-DILITHIUM, RingCT2.0. Layer two (Execution Layer) is something underlying and specific. Layer three (Applications Layer) is our t-dApp from the t-dApps library.
