View source for Lower Level Library (LLL)

The Lower Level Library (LLL) is the foundation for the TAO Framework. It is a base template library written in C++ minimizing hardware abstraction, thus maximizing bare metal efficiencies. Architecturally, the LLL is an interchangeable construct requiring logical development of templates and modules for specific functions. The LLL-TAO or TAO Framework is a series of LLL templates and data models that are accessible through a simple JSON-based API, allowing any type of developer to improve their application’s security, scalability, and robustness.

The LLL contains three main components: Cryptography (LLC), Database (LLD), and Protocol (LLP). There are several representations of LLD in the stack; Ledger, Register, Operations and API. The LLC is primarily applied at the Ledger layer although can be implemented elsewhere. As a component of the Network Layer, the LLP is designed to be a light, fast protocol that allows a developer to customize their packet design and message interpretation.

== Lower Level Crypto ==

'''Set of Operations for handling Crypto including:'''

* Digital Signatures (ECDSA, Hash Based)
* Hashing (SHA3 / Notable Secure Algorithms)
* Encryption (Symmetric / Asymmetric)
* Post-Quantum Cryptography (Experimental)

'''Currently Implemented:'''
