Build simple Substrate runtime modules with a tutorial

[EdwardAThomson]

We need more tutorials that help developers get acquainted to building for Polkadot. In this bounty we desire the creation of a tutorial that leads fellow community members through the necessary steps of creating a Substrate runtime module.

Example project 1:
Create a simple module that hashes a piece of data and stores it on chain (please include a timestamp). The module must be also be able to check the hash and timestamp.

This task should include a simple UI plus a tutorial.

Example project 2:
Taking inspiration from Gavin Wood’s talk at W3S, we would like a tutorial that teaches the community how to build a simple game that uses a Substrate runtime module.

This task should include a simple UI (e.g. in a web browser) and include a tutorial.

Example project 3:
Take inspiration from the above example projects and come up with your own Substrate runtime modules.

It is likely that you will have to create a simple UI, plus you need to write an accompanying tutorial.

Requirements

When undertaking the work for this bounty, be advised that a correct submission will:

• Be open source. This work will be shared widely with the community.
• Have a step-by-step tutorial that explains how to write the module. The tutorial will explain the reasoning as to why the module is designed as it is.
• The module must function as requested and contain no compiler errors.

Bounty

This issue now has a funding of 900.0 DAI (900.0 USD @ $1.0/DAI) attached to it as part of the Web 3 Foundation fund.

Just as an FYI for all bounty hunters: the total pot of funds is 900 Dai, but we are looking for 3 submissions. That means that each individual submission is eligible for 300 Dai.

Keep this in mind while applying! Thanks and good luck!

@EdwardAThomson Is this issue still open? I want to work on this. I don't know much about Substrate run time modules or polkadot, but I think I can figure it out. I think I can write the tutorial better as I will also be trying to figure out how to create the module myself, and the tutorial is targeted for the first timers like me.

Tell me if it is available to work on. Also should the three example projects listed needs to be created or any one of them is fine?

Hey @pbteja1998 this bounty is definitely still open! Thanks for reaching out and good luck with your submission.

@EdwardAThomson
Where can I contact you if I need any clarifications, is there some slack or gitter channel that I can join?

Also Should I make tutorials for all the three example projects listed or just any one of them?

Any one of them is fine. We just wanted to provide some example ideas.

I recently joined the Gitcoin Slack but I barely visit. We do prefer to use Riot at W3F. I can also ping you an email, I see the address in your profile.

@EdwardAThomson thanks. I just joined the riot channel.

This is awesome!

I'm currently exploring building web2/web3 data bridges to enable on-chain voting mechanisms. If I got this to work on Substrate, explained how to replicate it, and created a way for people to get involved to improve the architectures/protocols would that count for the bounty?

Also, does the Polkadot testnet pool security/validator actors yet, because that might change design decisions?

Thanks :)

[EdwardAThomson]

This is awesome!

Thanks! @burrrata :-) I'm appreciating the enthusiasm.

If I understood correctly, yes.

Almost any tutorial that shows people how to build a module on Substrate is acceptable!

In theory yes, but there has been a few hiccups getting our new hybrid consensus mechanism working. This has slowed down the deployment of test parachains, although we did see a couple on the previous test net.

Hi! I just completed a module for a Bonded Token, also known as Bonding Curve Token or Bonded Fungible Token taking inspiration from this EIP for a smart contract.

What I did for this is to implement the runtime module for an ERC20 token that can be bought and sold continuously for a price which is a function of the total supply. Code is available here. So far I've written a tutorial walking through the Rust code portions and still needs some editing and a better home for publishing it besides my random GitHub repo 😅

I'm wondering if this would qualify for the bounty?

[EdwardAThomson]

implement the runtime module for an ERC20....

Hey @lsaether , thanks for showing interest. That sounds like an impressive effort, so this would be eligible for a bounty!

I'd like to have someone check over it before awarding any funding. We would check that the code works and that the tutorial is clear enough. I've asked someone on our side to take a look and verify it for me. :-)

For high quality tutorials, I believe it should be possible to get them hosted on the Substrate hub site. I don't have any editorial input there, so I'd need someone from Parity to inform us.
