Logos Network System Design Overview

This document summarizes the high level system components that reside within the Logos core software. The break down of the components are purely functional and does not reflect the actual software design. This document gives a clear view of all functional subsystems of the Logos core. For details software design and its associated logical break down, please reference the detailed software design.

Note that some of the components have been refactored and the design documents have yet to be updated. Additional design documents are also located under our SDF repo.

Functional Components

The Logos core software is a direct implementation of Logos core software requirement document (SRS) and it realizes the requirements detailed in the document. The SRS itself is directly derived and traced back to the white paper. This allows the software the software to directly reflect the design of the white paper. There are many functional components required to realize the design and they go beyond what are called out in the white paper. The entire core software can be broken down into the following functional components:

• Consensus

• Epoch Transition

• MicroBlock and EpochBlock

• Token

• Election and Staking

• Identity Management

• P2P Network Maintenance

• P2P Network Stack

• P2P Options and Feedback

• P2P Database

• P2P Consensus

• Reward

• TxAcceptor

• Heartbeat and Reconnect

• Block Cache

• Bootstrap

Please note that the bootstrap component has been refactored.
