 As a decentralized Network, the state of these is replicated across all of the distributed Nodes in the Network by forming a Blockchain, in which Consensus on transactions transmutes to the final immutable state.

 [Narwhal](https://arxiv.org/abs/2105.11827) and [Bullshark](https://arxiv.org/abs/2209.05633), are high-performant mempool and consensus engines by [Mysten Labs](https://github.com/MystenLabs). The Fleek Network uses Narwhal as a DAG-mempool for transaction ordering that requires total ordering (linear order) and Bullshark as the consensus engine.

 Abstraction is conceptually useful in decentralized and distributed Web Service development because of how incredibly complex it can become and the speed at which developers have to react to the outside world. The core team put most of the complexity into well-defined building blocks.

 [Draco](https://github.com/fleek-network/draco) is the repository name containing the Fleek multi-service Edge Network implementation.
 
 The project aims to provide a higher focus on engineering productivity from the get-go, an improvement over the original [Ursa](https://github.com/fleek-network/ursa) implementation, which was exclusively focused on CDN, one of many services Draco offers support.

+### Interfaces
+
+The design pattern adopted for this software is highly inspired by the Object-Oriented model described by Alan Kay, which may be a bit different from OOP which grew to fame due to Java.
+
+In a nutshell, this is similar to the same idea, and we represent different units of computation and process as objects that communicate with each other by message passing.
