Hello Bitcointalk,

I am looking for resources relating to bitcoin scripting /transaction automation.

These would be shell scripts that can automatically execute bitcoin transactions.

I would like to learn more about how I can program bitcoin transactions so I can develop automated interaction with the blockchain.

Ive seen transactions on the blockchain where bitcoin is automated and it skips around the blockchain to new addresses automatically without a physical person signing those transactions and I want to figure out how these people are doing it. Is there a software for this automation or is it raw back-end shell scripting?

There are little to no You-tube videos on this topic or substantial resources I have been able to locate.  

Thank you in advance for your time in locating any resources and trying to help me.

Highest regards,

-Eclipse

So if I'm not mistaken, you wanna try looting puzzle 66 as soon as it moves, right? But what you are asking is kind of a hacking bot, so it's gonna cost you some money, besides why would any looter help the competition? 😉

Hello Eclipse.

Bitcoin scripting isn't hard at all, it's easy if we understand how to create/sign/send transactions with the bitcoin core.

Create a transaction:

Sign the transaction, and get back the hex:

Send the transaction (signed hex):


Source: https://developer.bitcoin.org/reference/rpc/sendrawtransaction.html

But to make the script you need to know the inputs for building the transaction, you can get that information from:


Once you have the right inputs from the list unspent (txID and Vout) you already have all the data and the tools to create the script.

Check out BitIDE, it has a full IDE, visual debugger, and integration with local testnet:

Looking at the resources you've linked, I get the feeling you're mixing up 'scripting Bitcoin transactions' which means creating Bitcoin transactions programmatically and 'scripting Bitcoin' as in 'using the Bitcoin scripting language'.

You don't need to write any custom Bitcoin scripts (in the Bitcoin scripting language) in order to automate creation of transactions. Don't waste your time with the former; just use the bitcoin-cli as shown by seoincorporation and invoke it from your shell script or whatever programming language you prefer.

Alternatively, you could use the Bitcoin Core RPC interface through JSON-RPC calls from any programming language:

For createrawtransaction (https://developer.bitcoin.org/reference/rpc/createrawtransaction.html), it would be:

Instead of curl, you can use your chosen programming language's preferred framework to build and send a POST request.
