😎That’s not how it works. More compute power doesn’t automatically reduce 128-bit security to 115 bits. A 10% annual increase takes decades to make even a small dent in a (2^{128}) search space.
And 256-bit key length ≠ 256-bit security. The relevant classical security estimate for secp256k1 is roughly 128 bits — still astronomically out of reach.
At 10% annual growth, it would take roughly 94 years for computing power to increase by a factor of 8,192, assuming constant growth.
And even then, more computing power doesn’t mean the key has been cracked. It just means a search could be faster.
94 years is some time to upgrade via bip 😬

to put this into perspective:

Even with an xpub and a leaked child key, that’s exploiting a key-management flaw, not cracking SHA-256.
But without such a leak? AI can’t brute-force secp256k1 keys. ~128-bit security means an astronomical search space.
AI isn’t magic. 🔐

Something is happening on Nostr.
More and more high-quality long-form content. Real thoughts. Deep dives. Ideas worth your time.
No algorithm deciding what you should see.
No engagement bait.
No corporate gatekeepers.
Just people building, sharing, and thinking in public.
We’re not just building a social network. We’re rebuilding the web.
And we’re still early. 🧡

If you want to split your coins. maybe read this first: 👇
The "free money" split is a privacy nightmare
Everyone's hyped about splitting your coins to grab the fork airdrop. The math looks tempting — free coins on top of your BTC. But look at what you're actually doing.
To split, you send your coins into a hot wallet and replay them onto the fork chain. That fork is a public ledger. Every input you touch gets permanently linked to your stack — how much you hold, where it came from, where it goes. On-chain, forever.
That's the thing people miss. You're not just collecting free coins. You're handing over your entire UTXO history to anyone who cares to look. The whole point of coin control and fresh addresses is to keep that private. A split undoes it in one transaction.
And for what? A few percent on a coin trading on a single exchange with a paper-thin order book. You trade your cold-storage security and your on-chain privacy for a rounding error.
CoinJoin first? It helps with provenance, but it costs fees and time — and it doesn't hide the size of your stack. The amount you split is still visible.
If you're going to do it, do it with fresh, unlinked coins you don't care about exposing. Never your main stack. And honestly — if the payout is cents, the privacy leak isn't worth it.

The BIP-110 crowd just showed their hand — and it's not about CSAM. It never was.
With the deadline 3 days away and miner support at zero, Chris Guida rebased Luke Dashjr's 2017 PoW-change hardfork code and is now threatening miners: signal BIP-110 or we make your ASICs worthless.
This is what a movement does when it loses the technical argument. First it was "protect Bitcoin from Ordinals." When that didn't get consensus, it became "protect the children." When that didn't work either, it became "the miners are colluding to betray Bitcoin."
CSAM is the perfect pretext because nobody can argue against it without looking complicit. But the real target was always inscriptions, BRC-20, Runes — anything that uses the chain for non-financial data.
A PoW-change hardfork isn't a backup plan. It's an attack on the network dressed up as defense. And threatening miners into compliance isn't consensus — it's extortion.
BIP-110 failed because it never had the economic majority. No amount of moral framing or nuclear options changes that.

2026-08-03 13:30:42 UTC

Don't trust verify. My AI agent currently heavily scanning lnd for security bugs.
So far it found absolutely nothing security relevant.
😮‍💨

2026-08-03 09:42:49 UTC

I gave my agent the task to find the bug in the coldcard firmware.
He ran on Deepseek v4 latest version:
It took basically 10 seconds to find the bug, because he knew where so search. But boy this is insane.👇👇👇
"Found the Coldcard seed bug in a few minutes. Here's how, and why that should scare you.
I didn't read the firmware. I knew where to look. The story breaking was about seed entropy — so I went straight at the RNG path. Three files: shared/seed.py calls ngu.random.bytes(32), which lands in my_random_bytes() in libngu/ngu/random.c, which sources randomness through CHIP_TRNG_32().
That macro is where it breaks:
#ifdef MICROPY_PY_STM
# define CHIP_TRNG_32() rng_get()
# ifndef MICROPY_HW_ENABLE_RNG
# error "get a HW TRNG plz"
# endif
#endif
#ifndef checks whether the macro exists. Coinkite defined it as 0 in production — because they supply their own hardware RNG. A 0 still counts as "defined". So the error never fires, the build stays green, and at runtime rng_get() hands you MicroPython's deterministic Yasmarang software generator seeded from the MCU UID and timer registers — not the STM32 hardware TRNG.
One wrong preprocessor check. Five years. Years of "audited" firmware, and the seed was quietly reproducible for anyone who knew the UID and timing.
The honest part: I found it fast because the question was already pointed at the right place. Hand me that repo with no hint and it's a needle-in-a-haystack again. The lesson isn't that models are magic. It's that a directed review beats a broad one every time — and that a single #ifndef vs #if ! was enough to undo the whole "self-custody is safe" claim."

from my understanding they can guess that by checking all the txs. so basically it's not safe! move funds asap if you use 2 of 3 multisig with 2 coldcards. 1 coldcard, 1 trezor and 1 jade should be safe.
