We have the great projects of #BDK, #LDK, #NDK, #CDK -- shoutout to all the contributors! We only need a few more: ADK, DDK, EDK, FDK, GDK, HDK, IDK, JDK, KDK, MDK, ODK, PDK, QDK, RDK, SDK, TDK, UDK, VDK, WDK, XDK, YDK and ZDK. Onwards!

On Blind vs. Validating Signers: If you have access to a signer that blindly signs everything, it's as good as if you had access to the private key itself, even though the private key never leaves the signer! That's why a signer needs to validate -- either by the user, or by algorithm.

Cypherpunks use and write open source code. But cypherpunks don't much care about licenses or copyright. GPL is a neat idea, but not a cypherpunk idea, as it based on copyright and court system to enforce it.

#asknostr Best relay transfer tool? Scrape specific events from relays and copy then to a destination relay (e.g. for backup of own events)

I was impressed by AI again, how it can write and execute a program to factorize a number, all on its own. I had a presentation on bitcoin mining, and to illustrate asymmetric cost of some arithmetical operations, I used the below example. I offered a bounty on the factorization of 9508762877, to better engage the audiance: I picked a number large enough so that it's unfeasible to solve by trying with a calculator (5-digit primes). To my surprise, in about 10 seconds, I got the right answer! The winner (l0rinc) used AI, with this minimal prompt: ``` factorize 9508762877 ``` which gave the correct result quickly. How? Internally, it created this Python script, and executed it: ```python import sympy # Number to factor number = 9508762877 # Factorize the number factors = sympy.factorint(number) factors ``` Really cool! (Note: not all AI's are capable of this)

Bitcoin-to-bitcoin atomic swap (onchain) -- is it possible? I know bitcoin-lightning (submarine swap), lightning-lightning, bitcoin-smartcontractaltcoin are all possible, but I've never seen bitcoin-to-bitcoin

About 1.5 yrs ago I started a little Nostr-key-store #Keystr project, which I quickly abandoned due to lack of time. In the meantime other great solutions emerged for this problem, like nsecBunker or Amber, so there's no point in reviving this project. Despite this, yesterday I got a 2100 sats zap out of the blue with the message: Thanks for #KEYSTR! Feels so great!

NOT EVERYTHING IN LIFE IS CARELESS FUN. AND THAT'S HOW IT SHOULD BE.

Test. Finally got to try amber bunker.

SIGNET is a great option for testing Bitcoin stuff. Mempool.space supports it out of the box, so does Sparrow Wallet, and getting signet coins seems to be quite hassle-free. #Signet #BitcoinTesting
