Read an interesting Twitter thread: https://twitter.com/level39/status/1632240495396044800?t=qX8lpBQEB_C6IBBx8xILaA&s=19

from level39 (is he on nostr?).

The threat is about losing your identity when you lost access to your nsec or NIP05 domain.

I thing this will not a problem in the long run as I'm confident there will be several solutions on nostr regarding these problems (Delegation, key deriving, multisig, key invalidation, did on nostr,... to name a few solutions)

New release 0.5.0 of pynostr

In this release the timeout parameter has moved to the class init function.
relay_manager.run_sync(timeout=2) ->
relay_manager = RelayManager(timeout=2)
relay_manager.run_sync()

and

io_loop.run_sync(r.connect, timeout=2) ->
io_loop.run_sync(r.connect)

I added a new example for sending and receiving dms:

## How to setup your own relay with nip05 authentication

I'm using a contabo CLOUD VPS M with NVMe and I'm using nostr-rs-relay with sqlite.

nostr-rs-relay does not work on ubuntu 20.04, so I'm using ubuntu 22.04

I mainly followed
https://github.com/BlockChainCaffe/Nostr-Relay-Setup-Guide

Addionially I needed to install protobuf

apt install protobuf-compiler

and I added

proxy_read_timeout 1d;
proxy_send_timeout 1d;
to the nginx conf in location / { } of listen 443 SSL;

The config.toml needs to be changed and

[verified_users]
mode = "enabled"

must be added.

let me know if you have questions are getting stuck during setup.

That happened during moving to the new server. I shortly removed the nip05 requirements for debugging.

Using nip05 works quite fine in fighting spam. Especially as I can blacklist domains.

I will check this out, thanks.

I just learned that the nostr-rs-relay is confused when using the same pubkey more than once in the nostr.json for NIP05 validation.

Meaning not a single of my events was stored on my on relay 😥

2023-02-23T08:03:02+01:00

My relay wss://relay.nostrich.de run's now on a more powerful server. (16 GByte ram, 6 cores and NVMe). Using NVMe really makes a difference, everything is much faster than before.

There are currently some good offers from contabo.com (double amount of storage for free). They are quite cheap and a good starting point for your new relay :).

2023-02-18T15:17:01+01:00

I finished my first useful python script, using my pynostr python library.

The script fetches the complete list of relays from https://api.nostr.watch/v1/online and requests from all relays my CONTACTS event.

Then the script checks if date and the follower count.

Finally the newest event is broadcasted to all relays that have a old version of my contact list. The best part is that my script does not need a private key.

How do a client know which relays I'm using? I checked the NIP definitions but I did not found something.

It does not work on each client, but snort and amethyst are supporting this.

There is NIP-65 with kind 10002, but it is not used yet.

Any ideas?

It could be that your metadata were mixed up with some random account due to a bug in a client.

Hi #[0]

can you help me with encrypted messages? In the example in https://github.com/nostr-protocol/nips/blob/master/04.md it says:

let sharedPoint = secp.getSharedSecret(ourPrivateKey, '02' + theirPublicKey)

But what is happening when the actual prefix of theirPublicKey was '03'? I think we will then calculate the wrong shared_secret.

As I understand from https://crypto.stackexchange.com/questions/103442/convert-a-schnorr-public-key-to-a-compressed-ecdsa-public-key

I need the private key to convert a BIP0340 Public key into a secp256k1 ECDSA public key:

BIP0340 to ECDSA: Find out if the associated private key produces a correct or incorrect implicit y
-coordinate. If correct prepend 0x02; if incorrect prepend 0x03.

But as I do not have the private key, how can I assume it is always 02?

For example:

bob_priv = "4138d1b6dde34f81c38cef2630429e85847dd5b70508e37f53c844f66f19f983"

When I create the ECDSA Pubkey it is:
bob_pub = "03a1db8e8b047e1350958a55e0a853151d0e1f685fa5cf3772e01bccc5aa5cb2eb"

When I convert it into the BIP0340 key it will be:
bob_pub_340 = "a1db8e8b047e1350958a55e0a853151d0e1f685fa5cf3772e01bccc5aa5cb2eb"

If I use bob_pub_340 for creating a shared secret, I assuming a prefix of "02 " and build the wrong shared secret.

I'm confused now.

It looks and feels like a native app.
