Overview

znn.js

znn.js is a community-backed javascript SDJ for the zenon.network project. The implementation is based on the official Dart SDK.

Minimal requirements

allow devs to create addresses from a mnemonic
allow devs to create the hash of a block
allow devs to sign a block

In theory, this will allow any JS-client to be able to interact with the ZNN network in a rudimentary way. All read operations can be done as depicted in the who-to-delegate tool @ source code here.

Snippet of code depicting a embedded.pillar.getAll RPC call

$.ajax({
    type: 'POST',
    url: 'http://ip-of-node:35997',
    crossDomain: true,
    data: '{"jsonrpc": "2.0","id": 30,"method": "embedded.pillar.getAll","params": [0, 150]}',
    beforeSend: function (xhr) {
        xhr.setRequestHeader("Content-Type", "application/json");
        xhr.setRequestHeader("Accept", "application/json, text/plain, */*");
    }, success: function (response) {
    }
})

Add browser-wallet-manager

When using the SDK in a browser environment, the developer might expect to find/store keyFiles in cookies / browser session.

This requires a lot of moving pieces which I’m not aware on how to deal with at the moment.

The cookies/session storage is just an idea. I’ve never actually done anything remotely similar to this before If anyone has any thoughts on how this works/what to expect, please hit me up E.G: a project/medium article that simulates a directory structure/file system in the browser-session/cookies will be of amazing help 🙏🏻

Hey - added some node endpoint requests

Hey Alien Valley,

I saw your JS SDK and thought it was a good entry point into learning about the Zenon Network and how this is all structured. Currently I have finished the znnplayground found here: https://znnplayground.com/. (It only works on http now for a WS/HTTP request, otherwise you get a SSL error)

I added more function to the src folder, do you want that file (I just copied all the requests basically, not written custom ones). But I managed to make the websocket and http request use the same structure you provided. Now I will continue to learn about the network and see if I can build some more onto it.

Empty array in 'api.ledger.getUnreceivedBlocksByAddress'
Test prerequisit:

Transaction sent from account A to account B, but not received yet

Test

Use 'api.ledger.getUnreceivedBlockByAddress' with address of account B

Result is { list: [], count: 1, more: false }, list is empty

When unning the same api function with the dart SDK the list array has one transaction in it

Add Flags in cli

The Dart znn-cli tool has a lot of cool flags which can be used here as well. As a design decision, the JS version should be as close as possible to the Dart one, where if makes sense, to not reinvent the wheel.

The following flags should be added:

FLAGS:
-u, --url           Provide a websocket znnd connection URL with a port
                    (defaults to "ws://127.0.0.1:35998")
-p, --passphrase    use this passphrase for the keyStore or enter it manually in a secure way
-k, --keyStore      Select the local keyStore
                    (defaults to "available keyStore if only one is present")
-i, --index         Address index
                    (defaults to "0")
-v, --verbose       Prints detailed information about the action that it performs
-h, --help          Displays help information

should be enabled only for WS connections

an error should be thrown by the znnd if called via HTTP

add momentum.listen in cli to test functionality out

Migrate PoW into znn.js
Migrate the znn-pow-links.js into the SDK natively.

test the blocking behaviour of generating PoW

only test in node.js scenario since running wasm in browser can be hard

or at least in extensions due to policy
