  • Making a decentralized app often means rethinking the whole structure of your application. It's rarely as simple as "change a few lines to sprinkle some blockchain in." (dare I say: never?) Storage and computation is many orders of magnitude more expensive, so you'll want to think about what stays on your servers and what goes in the blockchain. In general, storing data is as simple as creating a smart contract with a variable, and setting the variable value by issuing a transaction. – carver Oct 05 '17 at 21:28
