________________
In this short tutorial I demonstrate how to store hex data on the ethereum blockchain by signing an 0 ether transaction. This is a great first step for people to share texts and avoid censorship. As soon as a transaction is broadcast to the ethereum blockchain it cannot be tampered with. This is a level of trust that is not seen anywhere at the moment. There are many other blockchain platforms that allow this but we are only looking at the Ethereum Blockchain.

A chinese student used this method to avoid being censored by the chinese government.

What wallet like My Ether Wallet can I use to add data (the secret message) but in another network like BSC or MATIC, since the fee to go to My Ether Wallet is high :( thanks!

21cents is really expensive for that little text data. Does the cost vary depending on how much data you're storing?
