Analysis and comparison of IPFS and Ethereum SWARM distributed and decentralized file storage systems

V diplomskem delu smo raziskali, kateri izmed sistemov za porazdeljeno in decentralizirano shranjevanje datotek je učinkovitejši. Takšni sistemi nudijo alternativen način shranjevanja in prenosa datotek, pri katerem se izognemo centralnemu subjektu. Implementirali smo aplikacijo s pametno pogodbo, v katero se shranjujejo zgoščevalne vrednosti datotek, ki jih naložimo v omrežji Ethereum SWARM ali IPFS in po potrebi prenesemo s pomočjo zgoščevalne vrednosti, ki služi kot naslov datoteke. Nato smo testirali, kateri izmed sistemov je zmogljivejši, preprostejši za uporabo in hitrejši pri prenosu datotek.In this diploma thesis we researched which of the systems for distributed and decentralized file storage is more efficient. Such systems offer an alternative way of storing and transferring files in which we avoid the central entity. We implemented an application with a smart contract that stores the hash values of the files that are uploaded on the Ethereum SWARM or IPFS networks and, if necessary, are downloaded using the hash value as an address of the file. At the end we tested which of the systems is more powerful, easier to use and faster when transferring files
