Abstract
Blockchain is a rising technology mainly characterized by its decentralization, persistency, anonymity, and auditability. Due to these properties it is nowadays increasingly used in IoT and smart cities. However, the amount of generated data in these areas is large, and the size of the blockchain increases steadily as transactions and data are stored. To deal with this drawback, the blockchain technology must be adapted, in particular regarding its size. Indeed, after a few years of operation, Bitcoin and Ethereum blockchains already weigh more than 200 GB, which is impossible to manage for resource limited devices. Several solutions have been proposed, each with a different approach. In this paper, we try to overcome many of their limitations, by offering a solution that allows to greatly reduce the size of the blockchain by proposing an architecture specifically dedicated to the storage and manipulation of data, while allowing a free control and sharing of data by their owner.
