Serverless Blockchain Transaction System using AWS

Abstract

This paper presents a serverless blockchain transaction model built entirely on Amazon Web Services (AWS), combining AWS Managed Blockchain (Hyperledger Fabric) with AWS Lambda for smart-contract execution. By eliminating traditional server infrastructure, the proposed architecture reduces operational overhead, automatically scales with demand, and optimizes costs through pay-as-you-go billing. Integration with AWS Identity and Access Management (IAM) enforces fine-grained access control, while AWS CloudWatch delivers real-time monitoring and logging. Smart contracts run as stateless Lambda functions triggered by blockchain events, enabling a fully decoupled, event-driven workflow. Infrastructure provisioning is automated via AWS CloudFormation, and AWS Key Management Service (KMS) secures cryptographic keys. Comparative benchmarking shows significant improvements in scalability, fault tolerance, and total cost of ownership versus server-based deployments, making this model ideal for enterprise-grade distributed ledger applications.
