Abstract

Since the creation of the cryptocurrency Bitcoin, the interest in blockchain technology has increased, entering areas such as IoT (Internet of Things) and data sharing. The main objective of this paper is to develop a system that allows the storage of data from IoT services in a decentralized network with a blockchain managing transactions through a smart contract. The project was carried out using the blockchain Ethereum, IPFS (InterPlanetary File System) for storage, Solidity language for contract development, NodeJS for coding the simulation of IoT devices, web interface and back-end of the solution. The MQTT protocol was used to transport data from the devices. Our main objective was achieved, as the tests carried out show use cases in which this solution has an advantage over the direct storage in the Ethereum blockchain. (AU)
