@syonfox

or is it a just roll your own with sea kind of deal. ... is the user space accessible from other users. how does one publish a object that a user owns so others cant edit but anyone can see/decrypt depending on application

@Mac16661

How I can extract data return from content-addressing? Because it returning hash: data

Radu

@rococtz

@syonfox you never use public space for anything. you always use user space (with certify) or Content Addressing. For encryption see this

do you guys have any recommendations for increasing performance? i have a game and im using gun to sync player positions, calling .put(position) every say 50ms, but its pretty resource intensive and has a lot of latency

Radu

@rococtz

@lain:iwakura.xyz If you don't need to persist data (for example player position), why not use this one? https://peerjs.com/

also, how do you measure latency? latency between what and what?

hi @amark ! I'm sorry to spend your time for a very personal question, I promise I will be a fun of gun forever. ^^ The question is could you remember the link to the awesome tutorial of cryptography that you once provided in gun's documentation a few years ago? (In the new version gun documentation I cannot find it anymore.) I need this online tutorial to learn cryptography. thanks! ^^

@asd417

hi I'm new to this whole thing and I wonder how GUN handles proof of work or validating a peer's data

lain

@lain:iwakura.xyz

[m]

i had used yjs (a webrtc crdt database thing) before so i can use that for it i guess

Radu

@rococtz

@asd417 You can probably write a book about that :) But you can have a look yourself in the docs, maybe start with the Architecture chapter https://gun.eco/docs/

Or maybe this https://gun.eco/docs/Cartoon-Cryptography#cryptography for @SiJinmin as-well

SiJinmin

@SiJinmin

@rococtz yes, I have read these cartoons, but I want to learn the detail principles and algorithms for crypto, so I need a more detail tutorial about crypto. Thank you!

@NuclearManatee

a question about data modeling. How can I handle objects with arrays in it? Example:

let object = {
  scopes : [ 
    { name: 'a'},
   { name: 'b'}
  ],
  value : 'my value'

do I have any alternative other than decomposing the object and the array and saving into gun using gun.set() ?

Hey All, I am exploring the use of Gun in Expo following the ReactNative example. I guess I have some questions on dependencies, specifically in regards to SEA. It looks like Metro doesn’t support dynamic imports? I am getting the error "Dynamic require defined at line 5; not supported by Metro”, related to the use function at line 15 of SEA.js. Anyone have some experience using Gun in Expo, or interest in helping sort out a demonstration? I am interested in building a simple client/server monorepo that demonstrates basic auth and chat.

@u007

gun.unset code chnanged? my code didnt work
gun.user().get('coins').unset(gun.user().get('coin/code1'));

and also this issue

// does login here
let machines = gun.user().get('machines');
let machine = gun.user().get('machine/tesseract');
machine.put({faces: 24, cells: 8, edges: 32});
machines.set(machine);
// let's add machine to the list of machines;

let machine2 = gun.user().get('machine/tesseract2');
machine2.put({faces: 1, cells: 1, edges: 1});

machines.set(machine2);

gun.user().get('machines').map().once(() => {
    //this is called once only with machine, not machine2

})

@abow

if it did break, I'm guessing that rel and node aren't always "#" and "_"

[D]Alta: should I mod gundb to have the features I need, and risk having my version and the original try to talk with each other or should I write my own version from scratch?

@amark

@resession :clap: :clap: ! w000!
@u007 when Browser B makes a query, it gets relayed to Browser A even if Relay has 0 data, and Browser A serves the data, then this gets re-cached on Relay.
@gun-db-fan:matrix.org :clap: @rococtz !
@syonfox that was a bug in the CPU scheduled JSON parser I wrote the other month, see PR that has a fix we're merging, or tell GUN to use regular JSON not mine. Sorry :(
@lain:iwakura.xyz :clap: @finwo , or maybe user a webpack ignore fs etc. (?) Or one of you want to do a screencall with me to see why webpack has changed... for the 7th time in 5 years? They really make library dev life miserable by constantly changing.
@u007 wat? Several other apps (like Svelte Fireship one) all export gun.user() and then reuse it several other places, same as with vanilla. What env are you in?
Hmm, so maybe Browser is fine but NodeJS really doesn't like the User and isn't staying logged in?
interesting @syonfox !
@syonfox once() usually calls undefined if no data can be found within some timespan on the current network. However .map() will make things stream, so you'd want to .once(checkNotFound).map().once()
@lain:iwakura.xyz :sweat_smile: I'm glad you were able to figure it out and fix!
@NuclearManatee :wave: ! :) :clap: @lain:iwakura.xyz !
... will catch up later on rest ... (or ping me if still need help on some)

just got released, if anyone wants to download agregore, here is the release link

https://github.com/AgregoreWeb/agregore-browser/releases/tag/v1.0.0-44

gun-fetch README.md is outdated btw, i'll update it before i go to sleep

Thought this was pretty interesting idea and appropriate to some of the work here on SEA https://static1.squarespace.com/static/6182fa0bdec2ad76a2de22f0/t/61a54d333ed02a77d17716df/1638223155336/Polychain.pdf Not sure if the author is in this group anymore he was in the discord fro awhile

[D]Alta: What happened to Amark?

Hsingai Tigris Altaica

@DrAlta

gunDB is awesome but I think I just want to use it because if I make a cool piece of software with gunDB the gundb community will talk about it... and using it asa marketing ploy seems wrong....

@GideonWislang

@amark How would you handle cross-signing with metamask public key and signed message

tedd pasta

@azdez:matrix.org

[m]

i have a dilema. i can either save secret/private keys in memory and on-disk. it will be encrypted of course, but still less safe since i will hold the data. or i can recreate a function i need from the dht/bencode module that the webtorrent dht uses, this would mean if the webtorrent team/feross ever updates that original function then it will break my module until i update mine and match their changes, this choice is safer though since i am not holding any secret/private keys, i am only holding signatures, so much more safer. which would you rather do?

tedd pasta

@azdez:matrix.org

[m]

i'll go with the second choice, safety comes first.

@ranon-rat

Im having a little bit weird problem

im trying to put some data in a row or something idk called users

and idk why is giving me a problem

here is the error message

gun.js:1008 Uncaught TypeError: Cannot read properties of undefined (reading 'push')
    at walk (gun.js:1008)

someone can help me?

Radu

@rococtz

@ranon-rat can you share the code?

Mark Nadal

@amark

@syonfox (1) aliases are not unique so never use them for security things, only ever as an approximate search (2) grant is deprecated until future refactor, use .certify( instead like @rococtz :clap: linked.
@lain:iwakura.xyz if clocks aren't NTP synced, the latency is simulated. Sync has been fast enough for several other games, for years, what latency are you seeing? I'd love to try your game - I'm working with a couple others on some new ones too! Be cool to swap notes.
@SiJinmin :clap: :+1: @rococtz ! If not the cartoon, then which curves are detailed in https://gun.eco/docs/SEA . But I'm pretty sure you're probably remembering the cartoons.
@asd417 ^^^ :)
@NuclearManatee if you can tell us how you want array concurrency handled, then you probably understand why arrays are indeterminate without additional data, but can show you some hacks to wrap them.
@tyrauber :wave: :) this was just fixed by @aethiop use latest github and follow https://gun.eco/docs/React-Native instructions. Also he's just workign on an awesome tutorial too, I don't think finished yet tho: https://github.com/aethiop/jot !
@u007 I tried to replicate, I got both machines here. In-memory, no peers. You connected to peers?
@abow they're always that.
discord@Alta :wave: most features can be built ontop, including other CRDTs in 12 lines: https://gun.eco/docs/Counter . What are you wanting to make?
@azdez:matrix.org :fire:
@i001962:matrix.org :+1:
@DrAlta :laughing: no shame.
@GideonWislang pester https://twitter.com/shannonNullCode because they promised 5 times to upload their metamask login example and still haven't :P
@azdez:matrix.org :)
@ranon-rat :wave: this error message is fixed on GitHub latest, @rococtz this is when GUN().get('top').put('primitive') root level nodes need to be objects. Code crashed before getting to error message, been causing confusion for people, latest main properly logs what to do. Sorry about that!
