The problem Dcloud solves

For storing files and data online, most of us use cloud services provided by an central authority. We have to buy storage space in bulk and want to make payment regularly to access and store our data. As datas are stored in central system. there is a chance o loosing our data in case of a failure in the system and our data could be manipulate.
Dcloud provide sollutions to this problems. Our data can be stored securely in blockchain and it is immutable and no one can manipulate our datas. And payment need to be done only once. We use Filecoin to store the data, and the hash is stored in mumbai(polygon testnet)which runs on ethereum evm. Now everyone is able to upload their files in blockchain with ease.

Challenges I ran into

Had to face lot and lots of errors, mainly during compile time and during deploying. And i was able to get most of the solution from stackoverflow, rest done with googling and previous knowledge.
