Saw some talk about the benefits of running your own node with HD wallets. So I thought a super simple guide would help those who aren’t very…

I mentioned earlier that I wasn't sure if you can actually run full nodes on mobile devices. ABCbits gave two options for this: ABCore and Smartino.…

Hey all. Quick question. When I wanna create a raw transaction in Sparrow, do I need to make it unsigned if the other signer needs to add their own…

Been diving into the whole NSA tampering thing with crypto standards. Seems like a scare tactic to make us doubt the math itself instead of just the…

I wanna talk about how many think it's necessary to have a dedicated server for stuff like faucets or wallets. But here’s a cool trick: you can just…

Hey everyone, Been diving into Bitcoin books lately. Got a few things bothering me though. How exactly is the timestamp on a mined block determined?…

Just found oooo $OOOO Contract: 0xf0a28bddac9d3045c95bf57df033e80685d881c0 So what’s this all about? - It automates cross-chain actions using plain…

Hey all, I'm struggling with Bitcoin Core. I want to create a new wallet there and import a bunch of addresses or descriptors from Sparrow. I managed…

Drop your Bitcoin Testnet4 address here and grab up to 0.02 tBTC4 per request. New accounts get less, but watch out for limits due to abuse. If you…

Anyone tried looking at the BTC Puzzle? I think we should simplify it using a probabilistic approach. Like, if we analyze the keys we've found, most…

BIP-110 is really dividing opinions. Some folks think we need limits on transaction data, while others are totally against it. I’m curious how…

Quick question here. If I run listdescriptor and then importdescriptor with an exported file on a new system, will I still have access to the same…

There's some buzz about a new study that claims we can predict the next prime number. Sounds wild, right?

So, like, each node in Bitcoin doesn’t really have a physical address, right? It’s just scripts. What I get is that a Bitcoin address is more like a…

I’ve been trying to set up a solo mining pool for Bitcoin just for privacy reasons. But I can’t find a no GUI version of Bitcoin Core. No idea how to…

How do we even tackle this topic? Like, who knows how the secp256k1 generator was created? I was chatting with someone who claimed no one knows, but…

I'm really worried about increasing OP_RETURN size. Just think about it, storing CSAM without any disguises... not cool.

So I’ve been looking at this BTC puzzle thing. You know, trying to find a private key for an address. I noticed some pools, like ttdsales, seem to…

Ark is basically a solution to make Bitcoin transactions faster and cheaper, right? Like, it’s supposed to help with scalability and privacy too.

Hey, I'm not super technical but I saw this slide from River. 276,000 code changes seems really high to me. ChatGPT said it means 40% of the code…

Hey all, I wanna know how to enable full RBF. What’s the first step to get started?

I was curious about how long it takes a regular PC without a GPU to fetch a key in the range of 2^74 to 2^75. So I coded my version of the kangaroo…

Code's working, just need a little more support to get the privkey from the pubkey, about half from dip. No useless algorithms, plz.

Hey all, I want to share my new project called ecloop. It's a tool designed to speed up the search for Bitcoin public keys (hash160) on the secp256k1…
