In my previous article, I talked about using a blockchain-based cloud (storj), but ethereum was only used for paying node operators. So in this article, I will give you ways for directly storing data on the blockchain.
1 - OP_returns
OP_returns are a way for putting messages on bitcoin-based blockchains. For doing that, we need for a compatible wallet.
We also can send files using bitcoinfiles !
2 - Ethereum hex tx data
3 - Tron transaction note
It's a bit the same principle as the previous, but we doesn't have to encode/decode data. Only add a tx note on tronlink.
4 - Using Hive/Steem
That's all !
It's the end of this article and I hope that you liked it.
If you want to try one of these methods, feel free of putting blockchain explorer link in the comments (it would be nice !)
If you liked it, plz give a tip and a like
And if you see anything to improve, feel free of saying it in the comments
