Abstract

This paper proposes an architectural and performance evaluation of smart contracts aimed at managing decentralized digital identities in permissioned blockchain networks. The analysis compares approaches based on Hyperledger Indy and Hyperledger Besu, considering fundamental operations such as identity creation, credential schemes, and revocation control. Metrics such as response time, throughput, resource usage, and scalability are analyzed to support decisions on secure and efficient infrastructure for digital identity in the context of digital public governance. The results show superior performance gains in the Besu-based approach, in addition to greater predictability in resource usage, reinforcing its potential for sustainable large-scale applications. Codes, contracts, and test plans are publicly available for reproducibility.
