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 canc

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.

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.

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.

Guilty >_> It feels nice when a protocol has its core devs on the same wavelength as application devs. That's the feeling I get with nostr.

So much FUD. 1) miners profit from energy surplus. They do not create new power plants. Nobody is firing up a new coal plant to mine bitcoin. That is absurd. 2) miners have incentives to find and use wasted energy. For ex, flare gas recycli

They do with the extended key as it includes the chain code.

My vote is for extended keys, something based off HD Wallets: https://github.com/bitcoin/bips/blob/master/bip-0032.mediawi... Easy rotation and recovery of individual keys, but you do have to protect you

You can argue that it is not true P2P, since you rely on a public-facing intermediary. A lot of p2p protocols cheat with relays, it is really hard to traverse nats otherwise. Nostr can be used for peer discovery to bootstrap a direct p2p co

Yes this is the crux of any social media application. I don't know if there will ever be a perfect solution. I like that nostr abstracts this problem away from the relays. Relays only focus on storing data and handling subscriptions. T

Great question! Relays aren't involved in curation or discovery, so it fall on the client. You can request very broad subscriptions from relays! For example, here is a site that subscribes to everything, showing you a gods-eye view of

Nostr is a stupid simple P2P protocol that works, built by builders

As a Bitcoin maxi this is fun to watch. It's like the 08' financial collapse all over again, but there's no bailout coming this time around. I think it is glaringly obvious at this point that most of society does not understa

The future of micropayments will be the Lightning network. It's still under heavy development, but people use it to stream instant sub-cent payments all the time. Check out stacker.news as a live example.

You can't rewrite the history of blocks that have already been distributed. You may fool SPV nodes but any node with a copy of the blockchain (even if pruned) will reject your version.

I don't think it's fair to base a topic on the loudest voices in the room. That is a road to madness. I still wish to see more interest in technical discussion of Bitcoin here. Like the new BIP proposal expanding the scripting cap

I think group e2ee is overblown and self-defeating in principle. Good luck auditing a ratcheting e2ee algo. Plus it breaks often, and group encryption is defeated by any user in the chat. Direct e2ee is far simpler and can be expanded to sm
