Hey all. Does anyone know what it means when the R value starts with 0? Also, how can I find the msb bits for a lattice attack?

What version of testnet is included with the Bitcoin Knots executable? I’m not on my node right now, but I recall seeing something like bitcoin-test…

So in Bitcoin Core, we can import descriptors and set which index the wallet uses for a new address with commands like getnewaddress. But currently,…

Hey everyone, I’ve been trying to set up my own payment processor recently. I found this script that supposedly generates all sorts of Bitcoin…

I've been trying to keep up with the blockchain, and it's just so massive now. Kind of frustrating to run a full node. What if there was an…

Just came across this proposal from devs about freezing Bitcoin on legacy addresses if they’re not upgraded to quantum-resistant ones. Does this put…

Can I make a Bitcoin address with a specific string? I don't wanna deal with private or public keys, just something unique to put on the blockchain.…

So there are all these block explorers out there, right? Some just show basic blockchain info, while others focus on UTXO and pruned data. But I was…

I’ve been using torrents for ages, mainly for old shows and movies that are hard to find. Recently noticed there aren’t many seeders for the Bitcoin…

So, I stumbled on this sketchy crypto wallet about two months ago. It’s linked to some serious pigbutchering scams with a ton of transactions. It got…

Hey folks, first time posting here. I've been pondering the whole client diversity topic lately and I’m curious to hear your thoughts.

I saw something interesting about secp256k1. The gcd of p-1 and n-1 is 6, which limits our options to lambda and beta for efficiency. But secp160k1…

So many quantum proposals floating around. Some good, some bad, but it's all quiet on the deployment front. I took a shot at deploying one of the…

Came across this post from a guy named Michael Saylor talking about 110 reasons why BIP 110 is a bad move. If you got some time, it might be worth…

I've been trying to link Spectre with Bitcoin Core for hours now. My config has rpcpassword=b and rpcuser=a but Spectre keeps rejecting them. What’s…

I’m sharing a public node for Testnet4. It’s not the fastest, but it works. If you need some tBTC, just hit me up in a DM. Totally free, no strings…

Hey folks, I posted about this a bit ago and thought it’d be easy... but boy was I wrong. Trying to make a Bitcoin inscription in C#. The libraries…

I’ve been really worried about the updates for the iancoleman/bip39 project. It’s the go-to tool for mnemonic recovery and super user-friendly. Last…

So, how does this extended private key thing work? I think it comes from the root key using a hash function like HMAC-SHA512. You end up with a value…

Hey all, I’m interested in sharing a different idea regarding legacy signatures in QRAMP. Instead of rendering ECDSA spends useless after a certain…

I just set up my bitcoin node and noticed some incoming connections labeled "npr" with addresses like "127.0.0.1:33686". What does "npr" mean? And…

I’ve been thinking about how we can optimize Eltoo once Schnorr MuSig is out. If anyone sees a major flaw in my idea or if it’s already been…

Heard that Satoshi had a line in Bitcoin's early code that rejected any block over 1 MB even before it was an issue. Pretty curious if that was a way…

Hey everyone, Could someone share 3 examples of r, s, z, and nonce data? Just need nonces under 100, if possible. Thanks a lot!
