It's not that strange. People tend to use what is popular.

There are several implementations of core across various languages, not including custom forks of core.

There was a section of IBM's quantum computing challenge that had you encrypt/decrypt logical qbits by transforming their phase state to a known degree. If the state was altered in-transit, than the inverse transform will not cancel out correctly.

the challenge also mentioned that for it to work in practice, the qbits themselves would have to be transported somehow.

Plot twist: this entire shit-show was orchestrated by chatgpt while inside OpenAI's basement.

> Austin was just a bunch of housed and employed people quietly dying because our government is anti-humanist.

Good lord.

It was a once in a century weather event. Austin and Texas in general celebrates a limited government. So you should take responsibility and prepare accordingly.

If you seriously feel like the city government is anti-humanist and out to get you, then maybe you should pack up and leave town immediately.

> I haven't yet heard a rational explanation for just how badly ECDSA mangles the Schnorr protocol in exactly the way that means a lot of implementations end up with horrible security holes.

I thought schnorr was under patent for a bit, so an open alternative was needed? Also ECDSA does allow for recovery of the public key from the signature, which can be useful.

nostr has an early NIP that talks about publishing timestamp commitments to the bitcoin blockchain, using the open timestamp protocol

it's not that big a deal if you use a hosted wallet. There's quite a few options out there, like stacker.news or wallet of satoshi.

You can use it as currency on stacker.news

You can tip people on the nostr protocol. stats are on zaplife.lol

you can tip musicians on wavlake

there's a Minecraft server called satlantis where it is used as a currency

there's a lot of plugins you can use to build your own lightning enabled apps on lnbits

the space is still young so a lot of software is beta, but there's plenty to play with

check out the plebdev course on udemy if you want to dive into lightning development

TLDR:

- Create two keypairs.

- Use ECDH to derive a shared secret.

- Use secret to tweak pubkey of the recipient.

- Send money to the tweaked (and hashed) pubkey.

- Recipient has to keep an eye out for this tweaked key on the blockchain.

Nostr partially addresses this in a few ways:

* Media itself is not stored, only links to media.

* Relays are free to limit usage, charge a fee or require proof of work.

* There are many kinds of messages with different storage standards i.e ephemeral messages are not stored at all.

Gas fees are also a solution to the halting problem that comes with Ethereum's EVM (and its Turing completeness). So you are paying for space and computation.
