Occam.Fi Challenge #1: Creation of a Haskell module to manipulate with cardano addresses (create random Byron, Shelley, stake addresses, ...), currently only possible in command line.

1. Rather than having to constantly access the cabal repl command line in order to acquire wallet addresses, which wastes time, we want a module which can be imported into a file and then allows for a function to be called to:

  • Generate a random wallet address (Primary goal)
  • Generate staking addresses (optional but extra credit)

2. Here is how we would normally go about getting a cardano dummy wallet address:

  • If on windows load up a virtual machine
  • Open the terminal in the virtual machine
  • Go into a nix-shell in /plutus/
  • Then navigate into the /plutus-pioneer-program/
  • Cabal build
  • Cabal repl
  • import Wallet.Emulator
  • import Ledger
  • pubKeyHash $ walletPubKey $ Wallet #

Pictured below is what it looks like:

So with the module, we would want to be able call some function and in return receive a random wallet address hash like this: 39f713d0a644253f04529421b9f51b9b08979d08295959c4f3990ee617f5139f

“Creation of a Haskell module to interface with Plutus modules to generate and manipulate randomized Cardano addresses so that we can easily and quickly access example addresses for wallets or staking contracts without having to go back and forth to the command line.”

Occam.Fi Challenge #2: Creation of a Haskell module to estimate transaction size/fee during testing.

“Creation of a Haskell module to allow for estimation of transaction size for different transactions based on complexity for each transaction. The module would allow us to call it and provide different custom transactions then receive estimated fees as an output.”

Adosia Challenge #1: Build an open source donation platform using Heidrun to accept the ADA donations and kick a callback to the core donation to issue an email receipt. The platform should meet the minimum requirements for community organizations to begin accepting ADA donations.
BOUNTIES: 300k ADO, 200k ADO, 100k ADO
Adosia Challenge #2: Build an open source native asset drop / contest distribution / participant management platform using Heidrun - let’s make it easy to distribute native assets / enable faucets.
BOUNTIES: 200k ADO, 100k ADO, 50k ADO
Adosia Challenge #3: Heidrun expansion challenge - let’s expand Heidrun functionality - perhaps add a TrackAssetPaymentAndCallback, or TrackPaymentAndDropAssetAndCallback methods - be creative!
BOUNTIES: 500k ADO, 250k ADO, 100k ADO

Adosia Heidrun Development Challenge:

Heidrun is an open source platform API enabling developers a simple self-hosted means to rapidly integrate accepting Cardano payments and/or Cardano native asset withdrawals directly into custom applications. Heidrun currently supports payment wallets, drop wallets, and two separate API job functions – a TrackPaymentAndCallback function enables setting up a Heidrun job to trigger a custom action (webhook callback) upon detecting a specific Ada payment. The TrackPaymentAndDropAsset function enables dropping a native asset on detecting a specific Ada payment. The TrackPaymentAndCallback API method issues a webhook callback upon detecting payment (leaves the inbound payment wallet utxo alone), and the TrackPaymentAndCallback API function consumes the entire payment wallet utxo returning any excess Ada amount to the target address along with the native assets.

SPOCRA Challenge #1: Create in-wallet on-boarding process to verify SPOs.
  • Validate SPO to authenticate membership
  • CIP-0022: Pool Operator Verification – use elements of this?
SPOCRA Challenge #2: Verification of requirements met to determine membership level
  • Block production
  • Membership fee paid
  • Owner (holds keys – identify verification needed/ many owners?)
  • Operator (completed apprenticeship courses/ tests successfully)
SPOCRA Challenge #3: NFT Badge held in stake pool address for members and removed if pool changes owners, membership fee not paid, minimum activity not met, etc.
  • Automatically remove NFT from wallet in not staked with specific SPO
