POCKET-JS, the NodeJS POCKET confirmer

What is the project about?

POCKET stands for Proof Of Concept Electronic Token (the K is silent).

POCKET is a project by @biophil. In a nutshell, it is a cryptocurrency that uses the STEEM blockchain as a base. It uses STEEM comments to execute commands such as sending tokens and confirming them.

The distribution of POCKET tokens has already stopped but many people still own some tokens and distributing them as tips via comments.

I started this project after seeing @sn0n asking @biophil if the project exists in Javascript on the following post:
https://steemit.com/pocket/@biophil/pocket-announcement#@sn0n/re-biophil-pocket-announcement-20180112t011307004z

The original implementation of the POCKET confirmer was developed with Python.

Screenshots

Here is a screenshot of @pode sending some POCKET to @dmaniabot via a comment. The transaction was then confirmed by @pocketjs

Technology Stack

Javascript
NodeJS
dsteem
JSON format for the file-based database
Docker + Docker Compose

Installation

Using GIT, clone the repository: git clone https://github.com/quochuy/pocketjs.git

Customizing the config file

make a copy of bot/config/config.distrib.json and name it config.json
edit the file and update set confirmer_account to your bot's Steem account username and confirmer_key to your bot's Steem private posting key
you might want to also set mode.test to true and mode.debug to 1 or 2 to increase log verbosity.

Once the confirmer is caught up with the head of the blockchain, you can set confirmation_active to true.

Running with NodeJS

You need to install NodeJS and then run the bot:

cd /path/to/project/bot
node confirmer.js

Running with Docker

You will need to install Docker and Docker Compose first then build the bot:

cd /path/to/project/bot
docker-compose build

Once the build is successful, you can run the bot with: docker-compose up -d
Check the logs with: tail -f bot/logs/bot.log

Generating a DB snapshot from an existing running Python confirmer

If you are already running @biophil's original confirmer written in Python and would like to help test this project, you can generate your own DB snapshot by copying the following file under the same directory as the blockchain_reader.py file:
https://github.com/quochuy/pocketjs/blob/master/bot/utils/convertDb.py

Then just run: python3 convertDb.py and this will generate a db.json file that you can just move into the bot/database/ directory of the POCKET-JS project.

Roadmap

The current version has been running fine for a couple of weeks already under @pocketjs but there are still few missing features:

replaying from block #1
replaying from Genesis
upvoting confirmation comments from other confirmers
rotate RPC nodes in case of connection issue
don't upvote or send confirmation comment until the replay reaches the head of the blockchain to prevent upvote/comment spamming

To run this script, it requires a post-genesis snapshot of the database. The GIT repository is currently hosting a DB snapshot as of 2018-07-06 at 6:00 pm AEST.

Ideas for extra features:

add an extra command (not part of the protocol) to allow requesting for an account balance: pocketbalance@user
create a simple blockchain explorer for POCKET

It's nice to revive project and not let them decay!
Let's hope it will be used :p

Let's go for the review:

Since the account doesn't have much Steems on it I'll write it: https://github.com/quochuy/pocketjs/commit/aefd1a49738bf72c926201b7da04e735ec25e42d#diff-e22b50e740e102c8de5e858dbcd7753dL6 => Never ever post your private keep! Github archives everything :p. You better change it now :D
https://github.com/quochuy/pocketjs/blob/master/bot/confirmer.js#L56 => Any particular reason for not using && since you don't have any elses ?
https://github.com/quochuy/pocketjs/tree/master/bot/test => You have a lot of tests and there are not useless this is awesome !
https://github.com/quochuy/pocketjs/commit/92f21722b6b30d12fdff588407789f55cf3a1a66 => Try to do a better job about your commits ha ha, can't remember... :-P, misc this is not serious, or having Validator or Add config twice. You can be more precise. Good comments are free!
It's nice to add a docker config. Really cool.

This a great job overall!

To answer the other questions:

password changed, thanks again
&& instead of elses is because I did a straight port from Python to JS https://github.com/biophil/pocket/blob/master/blockchain_reader.py#L135 and I haven't yet gone thru code optimization and rewrite as the primary goal is to get the JS version up and running with the same logic. So keeping things as close as possible to the original makes it easier if I spot a behavior that is different from the Python version.
The tests were very useful as I get to change code here and there as I go, this allowed me to make sure that I didn't break anything with the new changes and refactor.
hahaha, I'm often working on a train and then forget to commit as I rush down, three days later... can't remember things. Advice taken :-)
I do almost everything with Docker as it makes it so much easier to deploy or migrate

Thanks again @gregory.latinier

^{Someone sent you some POCKET tokens. POCKET is an experimental sub-token system which operates on the Steem blockchain. It's like having a custom token without SMT. You can also send some to someone else by just commenting on a post with the following command: pocketsend:number_of_token@recipient_name,memo for example to send 10 tokens to @pocketjs, make a comment starting with: pocketsend:10@pocketjs,This is a gift}
