Development & Technology

I’m diving into the technical side of Bitcoin and learning Python at the same time. I wrote a simple program to work with elliptic curves. I thought…

Some are worried about mining sustainability in the future. If fees aren’t enough to keep hashrate up, security could suffer. But changing that 21…

Hey folks! Just wanted to share the new CUDACyclone tool. It's super lightweight and hits 1.3 Gkeys/s on the RTX4060. The best part? It uses very…

Hey everyone! I just hit my one-year mark here and I’m excited! Got a lot planned for tonight, so figured I’d post now. Big thanks to all of you for…

Just saw the update on BitVM2... pretty cool stuff. It’s a way to run Turing-complete contracts on Bitcoin without messing with the consensus rules.…

Been checking out the splicing feature in the Phoenix wallet. So, does it actually erase the on-chain BTC trail? Here's what I'm thinking: 1. You…

What if we built a mini OS just for hunting down private keys? Sounds crazy but could be cool.

Nonce r from rsz is a coordinate of public key with privkey = nonce(k), which is the privkey of nonce pubkey R. R = E.Lift_x(r) R / k = G Can anyone…

So there's a lot of chatter about Bitcoin version 30 that's coming up. People are kinda worried about this OP_RETURN size limit lift leading to…

Just saw a proposal about adding a theft prevention feature in Bitcoin. Sounds interesting but also kind of risky. Anyone have thoughts?

Hey everyone, I'm working on a draft for a new API that could help people pull blockchain data easily without getting tangled up in legal issues from…

I’m trying to get started on testnet4 for my project, but I can't find any tBTC faucets. Can anyone send me some tBTC? Here’s my address:…

Moody mentioned that the analysis of the two other algorithm sets is ongoing, but these new PQC standards are key. He thinks we shouldn’t wait for…

Hey, I got a question about running a node. Didn’t want to clutter the challenge thread... So, while my Bitcoin core wallet is syncing, I see blocks…

Hey, is there anywhere I can grab an old version of Bitcoin? Like, Bitcoin 0.2 for Windows?

Came across a proposal in the latest Optech newsletter from Lucas Lima about Bitcoin. He talks about how fountain codes could let pruned nodes help…

Is it okay to use the same Bitcoin address multiple times, ignoring privacy concerns? I read somewhere that if the nonce k used for the ECDSA…

so how many transactions would actually be needed to shift all these quantum-vulnerable addresses to new ones? I'm not sure, but might be interesting…

I’m diving into this cool thing called the OMNI-UTXO protocol. It’s supposed to boost the BTC network. Anyone else following this?

Hey all. Kicking off a convo about keeping Bitcoin safe from future threats. So, there’s this idea floating around about holding back the public key…

So I had this BIP idea to reduce spam but realized it might mess up some stuff like Bisq and coin mixers. Gonna sit on this for now.

I'm curious... if I run one RTX 4090 on BSGS and another on Pollard Rho, which one is faster? Like, actual speeds per second and stuff. Anyone here…

Hey all. I'm kinda lost with this taproot address thing. How do I turn a hexadecimal private key into a taproot address using Python? I tried using…

Just stumbled upon this research. The author managed to extract a private key by exploiting less than 4 bits of nonce leakage through multiple…

I'm just starting with Bitcoin dev stuff but really want to learn. Been thinking a lot about how we can keep the blockchain from getting bloated.…
