Blockchain in itself is a very challenging technology. We worked on the 'Ethereum' platform using 'Solidity' language. Writing code in the 'Solidity' programming language was a very new as well as a challenging task. We encountered various problems during our coding phase because the syntax that were used in the language were new to us as compared to other programming languages that we used earlier. Other programming languages have inbuilt functions like searching,sorting,etc but here we have to code all these functions by ourselves. In our code we have written the 'equilibrium' function that was also too challenging to code. Apart from the coding phase the testing phase was challenging too. As the language was not familiar it was throwing a lot of errors during testing and the errors were not specified in the console either so it was challenging to find the errors manually and correct them. We also faced a small amount of errors while making the UI of our website that were solved gradually. We need to think a lot while selecting the color scheme of our website that should suit the website and its structure. Then comes the main part that is the integration of the frontend and the backend of the project. Using truffle is very difficult as there is no good documentation available online. We made this project when we have to attend all our lectures, practical labs of our college so we had very limited time to complete our project and we completed this project to the best of our ability.
