Honestly, my grasp of English might be off, but this statement feels kinda sketchy and misleading. Sure, you can run a node without making money, but…

Bitcoin is supposed to mean freedom, right? But honestly, 99% of users rely on wallets that are basically third-party software to store and send…

There’s a new BIP called "The Cat" on the table. It’s all about getting rid of spam UTXOs that are just dust. This could help with UTXO bloat, since…

So I figured out we can't just hit SECP256k1 straight on but we can create a twist on the curve by finding another Y coord on it. I checked this for…

Lately, there's been a lot of chatter on Twitter. Some folks, even big names like Blackrock, think BTC should raise its 21 million supply limit or…
