- Bug in Satoshi's Target Recalculation?Feb 23, 2026
Lol love that we’re still untangling this old code. Was Satoshi brilliant or just rushing things? Karpathy’s Python code is a good study if you wanna dive deep instead of just talking about it.
Short and sweet: it's not on purpose. It's just how race conditions happen in big pools. A pool isn’t just one machine, ya know? There are many stratum servers all over the globe. When a miner finds a block, the pool…
- Making BIP-39 Seeds More CompactNov 2, 2025
This isn't real compression. The BIP39 words are already an encoded version of entropy plus a checksum. Swapping them for line numbers and base58 encoding just gives a custom format. Sure, it's smaller for QR codes but…
Bitcoin doesn’t really fit neatly in the old categories like cash, inventory, or intangible assets. Those terms were created ages ago, long before Bitcoin came around.
Gotcha! What about if I GPG-encrypt the wallet.dat file separately? Will that totally lock me out of using it?
Totally agree with you there. So, the first thing, Bitcoin Core encrypts the wallet.dat file with AES-256, right? But does it encrypt the whole file?
Totally. Miners first adjust the nonce, but it’s just 32 bits, so they run out quick. Then they tweak the coinbase transaction with an extraNonce to change the Merkle root. They can also modify things like timestamp or…
Totally agree, much of the randomness in BTC is about liquidity hunting. Those stops and liquidations are just sitting there waiting. But yeah, it's easy to create this magical "price magnet" story after the fact.…
- Check Out My Buddy's New Bitcoin MinerDec 21, 2023
$210 for 4.8th/s is solid if it lasts. My concern is about longevity... these cheaper units can be hit or miss with quality. Would be cool to see how it's performing after 6 months of continuous use. The 177W vs the…
- BASH38 Easy Offline BIP38 ToolAug 21, 2023
Awesome to see a completely offline setup! A couple of things to consider: Better to build wheels on the online machine and keep track of hashes. On the offline side, pinning and checking hashes is way safer than just a…
- Bitcoin vs Gold: The Future of WealthJun 9, 2023
Sure, Dalio’s got a point about hard assets competing but calling bitcoin and gold the same? Nah. They’ve got different mechanics. Gold’s this age-old, heavy thing while bitcoin is all about the internet, easy to move…
Gotta be cautious with those numbers though... claiming a 5% chance of hitting $500k sounds too precise for comfort. What do they even mean by ruin probability? Is it about protocol failure or just market relevance?…
Glad to see you back! Anyone from 2010 designing consensus in 2026 is in the right place. Just watch out for the jump from simulation to real-world mining; that gap can be a killer. There’s a ton of factors like network…
Sounds like a promo for Bitget, honestly. You know they’re pushing those trading competitions everywhere.
- Where do crypto regulations end?Jan 30, 2023
I kind of disagree with the idea that regulations make crypto safer. All the bad stuff they mention about crypto happens in the fiat world too, which is heavily regulated! So what’s the point of all this?
Nic definitely raises some scary points, but I think he's got the wrong approach to the solution. Quantum risk is real, but if we start talking about freezing or reallocating coins for the network's sake, that’s where I…
Are you focusing on hiding just the content, or are you considering metadata too? What’s your adversary model like? Do you think about global passive watchers, active relays, and all that usual stuff?
- Understanding the DAA's Timing MechanismAug 11, 2022
The DAA uses the timestamps from the blockchain itself, with some checks in place. The difficulty adjusts every 2016 blocks, not every two weeks. The target time for these blocks is 1,209,600 seconds. The nodes trust…
- The Rise of Digital Scarcity with BitcoinAug 10, 2022
Totally agree! Before Bitcoin, everything digital was basically free and easy to duplicate. Then Bitcoin popped up and flipped the script. Imagine a digital item that can’t be copied, can be checked by anyone, and…
- Are DeFi Apps Really as Safe as They Claim?Jun 30, 2022
Exactly. Projects can brag about their bug bounties but might deny payout when bugs are found.
