Integrate with Algorand to allow ASA management

[jdvlio]

Overview

In the initial implementation, the authorization library facilitates the creation of Algorand Standard Assets on the Algorand blockchain. We will allow the following operations:

• Creating a DRT
• Sketch a trait FungibleAsset for managing assets

In milestone 1 we treat DRT transfer, redemption, etc. as a matter of convention and these operations will not be implemented in the current scope. Other tooling, like goal, can be used in the mean time for development and testing purposes.

Implementation

Blockchain integration using algonaut library.

An AssetCreationTransaction trait is provided which has an async create_asset() method, using the async-trait crate, that returns a basic result type.

The initial implementation of the library sketches the outline of an FungibleAsset trait by presenting an interface similar to that in ERC-20, as follows:

• name() which returns an Option<String>, representing the asset name;
• symbol() which returns an Option<String>, an abbreviation for the asset name e.g. USDC;
• decimals() which returns a uint32, the number of digits after the decimal point;
• total_supply() which returns a uint256, the number of minted assets;
• balance_of(address: &[u8]) which returns the balance of the address as a uint256;
• transfer_from(sender: &[u8], receiver: &[u8], value: uint256) which transfers an amount of the asset and returns some Result<bool,Err>;
