Abstract

This paper presents a solution for managing circuit requests in MEICAN, using smart contracts and decentralized storage through IPFS. The architecture integrates a Solidity smart contract, an API for interacting with the blockchain and IPFS, and web interfaces that simulate the circuit request and approval workflows. The evaluation was conducted in terms of gas consumption, demonstrating the feasibility of the approach for recording requests in a transparent, auditable, and immutable manner across inter-domain environments.
