Performance Evaluation of Decentralized Digital Identity Contracts on Ethereum-Based Blockchain Networks

Abstract

This paper presents a performance evaluation of smart contracts designed for managing decentralized digital identities on Ethereum-based blockchain networks. The analysis focuses on core identity lifecycle operations such as creation, update, credential schema definition, and revocation control, all implemented through Solidity smart contracts. Two execution contexts were considered: an environment using Hyperledger Besu operating in permissioned mode, and a reference to the traditional Hyperledger Indy model. The tests were conducted in a private network simulating different load levels and consensus configurations. The evaluated metrics include response time, throughput, resource usage, and scalability. The results provide insights to support the selection of efficient architectures for digital identity solutions based on Self-Sovereign Identity (SSI) and Ethereum, particularly in enterprise or regulated environments.
