Use of Blockchain in automotive industry

Algoritmi oziroma mehanizmi soglasja so ključni košček v sestavljanki verige blokov. Razvoj različnih mehanizmov soglasja je v porastu in prav ta košček bo kritično vplival na splošno adaptacijo in uporabo verig blokov v vsakdanjem življenju. V delu smo preverili, kako delujejo posamezni predlagani mehanizmi soglasij. Primerjali smo dokaz dela in dokaz deleža kot prva implementirana algoritma z dokazom pretečenega časa in dokazom požiga. Primerjali smo tudi ideje algoritmov soglasja, ki trenutno še nimajo praktične implementacije, kot dokaz sreče in dokaz oblasti. Raziskali smo, katere lastnosti mora mehanizem soglasja izpolnjevati, da pomeni izboljšavo tehnologije verige blokov. Ugotovljene lastnosti so nam postale merilo za primerjavo algoritmov soglasja. V delu smo pokazali, da lahko problem, ki ga je smiselno reševati s tehnologijo verige blokov, rešimo, in to celo bolje kot s pomočjo algoritma dokaza dela. Za izdelavo smo uporabili ogrodje Sawtooth z dokazom pretečenega časa, kot mehanizmom soglasja. Implementirali smo beležko vzdrževanj in popravil vozila, dobljeno rešitev pa smo primerjali z obstoječimi rešitvami servisne knjižice ter dokazali uporabnost in boljše delovanje verige blokov z alternativnim algoritmom soglasja.Consensus algorithms or mechanisms are a key piece in the blockchain puzzle. The development of different consensus mechanisms is on the rise, and this particular part of blockchain will critically influence the general adaptation and use of blockchains in everyday life. In this thesis, we examined how each proposed consensus mechanism works. We compared the proof of work and proof of stake as the first implemented algorithms with the proof of elapsed time and proof of burn. We also compared the ideas of consensus algorithms that do not currently have a practical implementation, such as proof of luck and proof of authority. We investigated what properties a consensus mechanism needs to fulfil to improve the technology of the blockchain. The established properties became the criteria for comparing consensus algorithms. We have shown that a problem that can be solved with blockchain technology can be implemented even better than with the use of a proof of work. For the implementation, we used the Sawtooth framework with a proof of elapsed time as a consensus mechanism. We implemented a maintenance and repair notebook of the vehicle, compared the solution obtained with the existing solutions of the service booklet, and proved the usability and superior performance of blockchain with alternative consensus an algorithm
