As the title says, i would like to know how to post a message to blockchain, as a proof, for future consideration
I want to write plain message, not to sign a message via some transaction, not to stamped a document.
Just a plain message, public to anyone via the txid
Thanks in advance
There are several methods to encode messages into the blockchain. You could send to addresses with words in it (like Vanitygen), send a transaction with certain amount of money (in hexadecimal) or many other methods. Some websites offer services to encode messages into the bitcoin blockchain. All of the methods require burning some coins because the messages are encoded in a transaction.
