Abstract
Cílem Bakalářské práce je demonstrovat blockchain databázi a chytrý kontrakt v oblasti elektronických mýtných brán.
Obsahem práce je rešeršní část vysvětlujicí základy technologie.
Praktická část vysvětluje oblast elektronického mýta a výběru poplatků za využití silnic I. třídy.
Jedná se o vozidla do 3,5 tuny a nad 3,5 tuny.
Za použití GPS souřadnic pomocí GPX protokolu by bylo možné vybrat poplatek jen za ujetou trasu.
Výběr mýta jen za ujetou trasu funguje u vozidel nad 3,5 tuny, u osobních vozidel
do 3,5 tuny tomu tak nefunguje.
Blockchain za pomocí chytrého kontraktu představuje řešení metody platby za trasu.
Představené řešení by také mohlo spojit platbu mýta obou kategorií.
V této práci jsou znázorněny nejdříve 3 návrhy.
Návrhy jsou v dostatečné míře okomentovány zhlediska jejich výhod a úskalí.
Z návrhů bylo vybráno jedno z řešení a to názorně zrealizováno.
Vybrané řešení umožňuje vytvořit mýtnou bránou na jednotlivých bodech GPS souřadnic a
následně uživatel si dokáže stáhnout informace o přítomnosti platbě mýta pomocí GPS souřadnic.
Realizace byla vytvořena a testována na soukromé testovací síti Ethereum blockchain.
Výsledkem se stalo řešení, které cílí na minimalizování počtu transakcí,
zlepšení pseudoanonymity a rychlost.
Při návrhu nebyla snížena míra bezpečnosti na úrovni blockchain nebo chytrého kontraktu.
Aplikace dokáže z definované trasy protokolem GPX zpoplatnit trasu.
Zpoplatnění je definované na jednotlivý bodech GPS souřadnic.
Goal of the Bachelor thesis is to demonstrate blockchain database and smart contract in the area of e-toll. The thesis starts with a research, which explains basics of the blockchain technology. Next is practical part explaining functionality of current e-toll in Czech republic. The first system of e-toll is for lorries declared as vehicles above 3,5 tonne. The other system is for cars up to 3,5 tonne. With the help of GPS coordinates and GPX protocol is possible to pay fees for only driven route. Similarly works the system for lorries, the system for cars does not work in this way. Blockchain with smart contracts introduce the solution of payment for only driven route. The thesis also represents the solution for joining those two systems of e-toll in area of payments. Firstly in the thesis are described 3 proposals. The proposals are carefully discussed about their benefits and drawbacks. The one proposal is then chosen and implemented. The chosen proposal allows to create toll gate on each GPS coordinate seperately. User is able to download the information about presence of a toll road by GPS coordinates. Implementation was created and tested on a local blockchain network. The result of the implementation is the solution that aims for better pseudoanonymity and overall performance of the whole network. There is also no decreased of security level on a layer of blockchain nor smart contracts. Application demonstrates simulation of driving on a toll road and on top of that creating payment for the toll. Simulation of driving is done by using GPX protocol. Toll gate can be created for each GPS coordinate separately.
