Nostr Web Client

Serious question from a non-cryptographer pleb and important discussion for the future of Nostr.

1. Private keys derive public keys; but is it possible to derive a new private key associated with the old public one? (And burn the old nsec)

—— In the regular world, I often change my passwords frequently for opsec. How does one protect their npub on Nostr? (Saying “be smart with your private key” simply won’t cut it if we want mass adoption)

—— is there a technical solution that would allow users to change up their nsec every so often to prevent compromise?

2. I’ve seen a few accounts here get compromised. What solutions do we have if this happens?

—— the only thing I can think of is having a second “ICE” npub posted on your bio that will only post in the event the main npub gets compromised. Not a perfect solution but could at least provide some assurance that the main account was hacked. (Granted most followers would never see it, but at least would provide some backup incase of anything nefarious being posted “as you”)

Obviously being smart with keys and using solutions like nsecbunker/extensions/signing devices is important, but they don’t address what happens should your main account be compromised. Anyone thinking about these things? #asknostr

To change your public key, send your coins to a new address that you control.

trees can be scary to programmers: lots of pointers flying around everywhere to different parts of memory, lots of memory allocations, but fixed and balanced trees have a very simple representation that you can store and navigate in a straight line (programmers like straight lines, we call them arrays)

The numbers in this image are the index into an array. Given any position in the tree, you can find a parent or sibling element with a few arithmetic operations which result in another index.

No allocating complex data structures, no chasing pointers around, just a bit of math to jump around a tree flattened into a straight line. As a programmer finding elegant solutions like this is a pure dopamine hit. Code can be beautiful 🥹

I agree with the elegance. This is how heaps are stored in arrays: https://en.m.wikipedia.org/wiki/Heap_(data_structure)

Choose Your Fate Game

Welcome to a text based RPG GROUP GAME by #[0]. We have selected a monster investigation. Anyone can participate and affect the outcome but you MUST reply directly to each specific action message with only the action number itself. The first reply each round will decide what action is taken. A pool of 300 satoshis will be split among all that participate correctly if the game is won. Good luck! This game will time out in 6 minutes if no one responds. #games on #grownostr #bitcoin

Welcome to the village of Ravenswood, a place shrouded in mystery and darkness. As you ride your horse buggy into town, you notice the weather is unusually gloomy, with thick fog enveloping the cobblestone streets. The village's welcome sign reads:

"Welcome to Ravenswood, where shadows whisper secrets and nightmares come alive."

Round 1: You arrive at the village square, where a small crowd has gathered, murmuring about the alleged monster sightings. What will you do?

1. Approach the crowd and ask for more information.

2. Ignore the crowd and head straight to the local inn.

3. Search for any signs of the monster on your own.

Choose wisely, for your fate hangs in the balance. [1698447000]

If you intend to go swim alone, what's a good piece of equipment you can bring for safety?

The smaller the better. An inflatable boat within a small bracelet would be perfect.

Sometimes I see people swimming with a surfboard in tow (but more commonly they swim on top of the surfboard). Most surfboards accomodate a leash, but note that it fastens at the back of the board and around your ankle.
