How to input custom data to blockchain?

[wsxdrfv]

So bitcoin is just input number's data (how many bitcoin some address have) on top of blockchain, right?

And ethereum custom it and can input custom code into blockchain, right?

Then how input own custom datas into blockchain?

For this purpose, one should either clone ethereum or using ethereum?

No. Addresses do not exist on a technical level. Bitcoin is 'made of' transaction outputs referencing earlier outputs, assigned to public keys.

No. For deploying contracts (code) into the ethereum VM you can't simply inject any code you want.
You will have to use solidity (most frequently used), LLL, serpent or mutan.

What kind of question is this ? EVERY data is encoded into 1's and 0's. This should already answer your question..

If you have to ask this question, you are definitely not able to properly build what you are trying to build.

If you want to post something to eth blockchain just google "ethereum oracles" and choose the service you like. I used chainthis.com few times to post some data to eth blockchain, the service is pretty easy.

When sending ETH you can enter input data, which is used as an option with every transaction.
Check this transaction

If you click on View Input on the bottom as UTF-8 you will see that the binary code is now converted.

This message is stored on the Ethereum network forever.

sending to unspendable addresses enables this feature
