Question

How do I send a "Hello, world!" message to an ETH address through DATA? That is would be visible on Etherscan That's the whole question

Is that possible in any way?

Answer 1

you can use eth.sendTransaction method to send the message along with the ether.

eth.sendTransaction({from:eth.accounts[0],to:eth.accounts[1],value:web3.toWei(1‌00,'Wei'),data:web3.toHex('Hello World!')})

In the mist wallet under send tab select the more option to add the message along with the ether transactions. In data, section add the text in hexadecimal format.
