12 bitcoin security levels: - level 0: on an exchange. You don’t really own anything. - level 1: hot storage on a closed source shitcoin wallet (like @Ledger) - level 2: hot storage on an open source bitcoin only wallet (like @bluewalletio or @SparrowWallet) - level 3: cold storage on a usb hardware wallet with shitcoin support - level 4: cold storage on a bitcoin only usb hardware (like @COLDCARDwallet mk4 or @BitBoxSwiss) - level 4: cold storage on a bitcoin only airgapped hardware wallet without reproducible builds (like @KeystoneForBTC) - level 5: cold storage on a bitcoin only airgapped hardware wallet with reproducible builds (like @foundationhq Passport) - level 6: analog-only airgapped cold storage (Passport supports this) with self generated ephemeral seed - level 7: cold single seed + passphrase (protect against seed compromise) - level 8: Shamirs secret sharing cold single seed (protect against seed compromise & introduce fault tolerance) - level 9: hybrid 2/3 multi-sig with 1 hot key - level 10: full cold 2/3 multi-sig - level 11: hybrid 3/5 multi-sig with 1 hot key - level 12: full cold 3/5 multi-sig Could be split up further but might not make a lot of sense. Bonus points for connecting to your own node at any level. I’m sure many will disagree somewhere. What would you change? What would you remove or rank differently? Note higher security is not always the best fit for your situation.

A main critique of shielded bitcoin: "it's not L1" and I actually agree! it's much more akin to lightning / liquid with a peg in and out That criticism is very valid, it's still a massive unlock for bitcoin privacy, a step in the right direction. Lightning for scaling, Shielded for privacy, All anchored on the most decentralized & secure money on the planet, doesn't sound too bad does it?

Don't upgrade to the new 2.0 version of umbrel. I lost everything and could not restore. Lost my Blockchain and different WillItMod apps that no longer load on the new version.

Everyone quick to point at the problem, Here’s a rare case of offering a solution One could also just Keep calm & stack sats
Cut rates to zero, cut interest on bank reserves to zero, buy back some of the debt with 0% T-Bills, let gold moon, instruct Warsh to revalue official gold to the new much higher price, depositing multiple trillions into the TGA, use the TGA to buy back to rest of the debt, voila

yeah so basically trump got cocky after succeeding with venezuela and had a hot hand and decided to double down and strike iran in february thinking they could take over the country in a couple of weeks despite everyone telling him it was a bad idea and would drag on nothing really happened and then Iran learned that they can actually close the strait of hormuz and were unsure if it would even work but now its become obvious they can do it and feel empowered. the iranians have a longer history as a culture and are slow walking trump as much as possible as they know that higher oil prices are going to ruin his odds in the midterms and weaken him not only that but now higher energy prices are putting upward pressure on inflation and bond yields which has made the job of his new fed chair warsh who came in under a premise of potential rate cute but because of the iran war were entering a rate hiking cycle the only person in the room who was trying to juggle all of this was scott bessent but after trying to juggle everything for so long he decided he was going to try and fight the bond vigilantes to lower bond yields and declared himself as the house. but he showed up to the bond fight with hardly any ammunition and now the bond market is calling his bluff and now the bond auctions are going terrible and he looks like a fool now so now bond yields are surging export bans on diesel are being put in place as an act of desparation midterms are a total write off and the trump admin is about to spend the next two years probably fighting impeachment hearings while things continue to detoriorate and the funny thing about all of this is he won the presidency off the idea of no more foreign wars but its his own foreign war with iran that started this whole mess and now the free market is testing them all

Personal milestone: my first change to a bitcoin BIP 🥳 A side effect of SeedSigner silent payments work The wrong spec told wallets to delete data that taproot signing needs, found by running BIP-376's test vectors through two wallet libs, embit (Python) and bwk (Rust)

We won't contain it We won't control it
today i've learned that 2 air gapped computers in the same room can communicate with each other by regulating their CPU temperature we're not gonna be able to contain AGI
Community note
Two air-gapped computers can communicate via CPU temperature regulation only if both are pre-infected with malware, placed within 40 cm, at 1-8 bits per hour as shown in 2015 research. arxiv.org/abs/1503.07919 gizmodo.com/openai-researc… windowsforum.com/news/openai-th… xenospectrum.com/en/openai-air-…
