Developing a Multi-Paxos Server-Client System with Python Sockets and Consensus Algorithms

Key Concepts in Multi-Paxos Implementation using Python

Imagine a stock trading platform where multiple servers maintain a consistent order of transactions across the system. Users demand real-time accuracy, but server failures or network delays threaten data consistency.

Here’s where Paxos, a robust consensus algorithm, shines. It ensures that all servers agree on transaction order, even in adverse conditions. Building a multi-Paxos server-client program in Python leverages socket programming for network communication and Paxos to maintain consensus.

What is Multi-Paxos?

Multi-Paxos is an extension of the Paxos consensus algorithm designed to handle a sequence of decisions, such as maintaining a consistent log of operations across distributed servers. It provides fault tolerance and is essential in systems where agreement across multiple nodes is critical. Key components include Proposers, Acceptors, and Learners:

• Proposer: Proposes values for agreement.
• Acceptor: Votes on proposed values.
• Learner: Learns the agreed-upon value.
