Welcome to the Distributed Banking System repository! This project demonstrates the implementation of a variant of the Paxos Consensus Protocol, applied to a distributed banking system. The system achieves consistency, fault tolerance, and reliability across multiple nodes, even in the face of failures.
This project is built to simulate a distributed environment where banking transactions are processed and replicated across 5 nodes, ensuring data consistency through the Paxos consensus algorithm. The system can tolerate up to 2 node failures without impacting correctness.
- Node Failure Tolerance: Handles up to 2 failures in a 5-node system.
- Local and Distributed Transactions: Supports both local transactions and Paxos-based consensus for distributed transactions.
- Block Construction: Combines multiple transactions into a block for efficiency.
- High Performance: Optimized for minimal latency (0.6 seconds per transaction) and high throughput (1.5 transactions/second).
- Java 17+
- Spring Boot
- Maven
- Clone this repository:
git clone https://github.com/MurtazaMister/Paxos.git cd paxos - Build the project:
mvn clean install
- Run the application:
run_servers.bat
- Client-Server Architecture: Each client is connected to a dedicated server for initiating transactions.
- Local Transactions: Transactions are processed locally if sufficient balance exists.
- Consensus via Paxos: For insufficient local balance, the Paxos protocol ensures global consistency by:
- Collecting local transaction data from all servers.
- Achieving consensus on a constructed transaction block.
- Broadcasting the committed block to all nodes.
