How to store data on a blockchain ?

By yanis | little crypto guides | 13 Sep 2020


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.

op_return example : http://explorer.bitcoin.com/bch/transaction/408362ec10137261b97c2c3b0ba63466e41475935c849bda48f3b38d7649297c

We also can send files using bitcoinfiles !

 

2 - Ethereum hex tx data

With myetherwallet, you can add arbitrary data to your ethereum transaction, but you'll have to convert them to hexadecimal format using tools like browserling or hexed.it

 

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.

Example : https://tronscan.io/#/transaction/ba0937fbf5200efe1d4899abd8d9bbfeb87c4b8433fab5aa69f4cc5f2bacaa71

 

4 - Using Hive/Steem

Steem (now Hive since a little problem with Justin Sun) plateform stores all its articles on a blockchain. I also can mention everipedia, that stores its wikis on a blockchain.

 

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 !)
