Excellent, many thanks! This really works. Amended the code for public address generation, too (now produces the same results as Bitcoin Core):
I've been playing around with these "dumb scripts" like this: Script("OP_DROP", "OP_1") is pretty basic but still valid. It accepts any single value, drops it, and just leaves a True on the stack. In hex, it's simply…
Found another interesting example. I call it "the nothing P2SH address". Because the script is NOTHING (code below). Here is how to calculate the address (Python command line): What's fascinating is its high activity,…
I'm not really sure what you mean. Yes, Bitcoin scripts can be infinitely complex, but hashes are only hashes (the "H" in P2SH), there are only so many opcodes, and the "only" thing your code needs to make sure is that…
Gotcha. Thanks for taking the time to explain. I find it a little funny you can easily create a transaction here, and then later broadcast it in Bitcoin Core without a problem at all, but not create it within the…
Thanks! If it really is the case that importmulti for P2SH with scriptPubKey and redeemscript can only produce watchonly-addresses in Bitcoin Core, I don't understand why the function exists in the first place since the…
Very interesting, thanks. Could you please give me an example with a what would be considered a standard P2SH address and its redeem script and a JSON-string that will be accepted by importmulti in Bitcoin Core? The…
I can replicate and confirm this, thank you. importaddress is for watch-only addresses though, according to the specs: https://bitcoincore.org/en/doc/0.20.0/rpc/wallet/importaddress/ However, importmulti specifically…
Damn, this is frustrating! The manual for Bitcoin Core says you can do it (import sigscript together with redeem script): https://bitcoincore.org/en/doc/0.20.0/rpc/wallet/importmulti/ But the closest I get is this…
Creating valid custom scriptSig/scriptPubkey combos is pretty straightforward. You can easily calculate a P2SH address, send coins there, and then spend from it with a bit of manual work. For instance: scriptSig Result…
- Risk takers keep pushing forwardMar 24, 2026
It is true that investing in Alt coins is as risky as gambling, there is no assurance of money by investing. Alt coins can disappear at any time, so I think it is completely foolish to invest money here. Bitcoin is…
A bank asking for screenshots? I can't imagine that. A screenshot has no legal value. I can make any screenshot you want on Photoshop.
We shall not say that Ukraine is a crypto-friendly country. It isn't. What's happening is that Ukrainians cannot trust their currency (like Russians). Most property deals in Ukraine are made with US $, and the biggest…
Great news, and of course the scammers' call is here https://twitter.com/Excellion/status/1264941244158898183?s=20
The question you shall ask yourself is what's next. What when the anonymous company wants to transfer funds to an individual? Or a non anonymous business? Most states or countries which allow anonymous companies are…
Yup. Downloading Bitcoin Core, letting it sync and run a blockparser will do the job. It's not fast and easy; in fact, most if not all block parsers I've tried require almost insane hardware and a decent amount of…
This is the best option if you're only interested in the current balance. For various reasons, I'm more interested in transaction history - e.g. "even if the balance is 0, has this public address ever occured on the…
If you, or anyone else for that matter, is interested in a copy - without download speed limits - I put a copy of the latest version here:…
I didn't know this one existed, many thanks! EDIT: Aha, so it is capped to 10 KB/s, so that it takes about 21 hours to download the file. Smart business model.
A pretty popular question you see around here is: "I've got thousands of bitcoin addresses. How do I check their balances?" I guess this is something people who are into hacking brainwallets or messing with BrainFlayer…
