Bounty Details

  • Bounty Amount: 200 ICP First Prize, 100 ICP Second Prize, 50 ICP Third Prize
  • Project Type: Single Contributor/Team
  • Opened: 03/28/2022
  • Time Commitment: Weeks
  • Project Type: Sample App
  • Experience Type: Intermediate - Motoko; Intermediate - Rust; Intermediate - Web


This bounty gives the opportunity to

  • learn motoko
  • learn rust
  • learn how scaling works
  • learn how to use canisters to create canisters
  • learn about indexing
  • learn how clients access the Internet Computer

The goal of this bounty is to produce a sample application on the Internet Computer.

Goal: Demonstrate scalability by using inter-canister calls

Create a practical dapp that has a common endpoint (primary canister) that can scale its application by creating secondary canisters and distributing requests across those canisters.

Reach Goal 1: The primary canister provides indexing information such that a client can distribute parallel calls across secondary canisters directly.

Reach Goal 2: Provide a security interface such that secondary canisters can hold private data from many users but only deliver requests to authorized requesters. Attempt to use as few inter-canister calls as possible.

Your application can be written in either motoko or rust. Further, a motoko and rust version can be submitted as seperate entries by the same person/team.

The code must be opensourced using the MIT License.

To submit for this bounty you should:

Create a github repo with your sample application and post the link to either the (dev forum post)[] or the (ICDevs.org dscvr portal)[https://h5aet-waaaa-aaaab-qaamq-cai.raw.ic0.app/p/icdevs].

We will start selecting prize winners by April 12th, 2022. Submission will stay open until we believe we have a sufficient number of sample applications. Multiple prizes may be awarded for submissions that reach a sufficient level of completeness.

Bounty Completion

Once your app is complete and submitted, it will be judged on the following criteria:

  • How relevant is this sample dapp for the community?
  • How well is the sample dapp’s functionality presented?
  • Does this sample dapp help me to build enough? Can I use the sample dapp for a real project?
  • How well was the sample dapp written?
  • How many goals were reached?

Bonus considerations:

  • Are there tests?
  • Is the documentation provided (readme file on github) sufficient?
  • A user interface of some kind is highly encouraged so that users of your sample application can get a visual view of how your application works.
