Proposed Technical Architecture of EstateDAO

EstateDAO is built on **Internet Computer Protocol (ICP)** and would be a truly decentralized platform, with both the front-end and back-end hosted on-chain.

EstateDAO would be a web-first platform, with the front-end application layer, consisting of progressive web-apps, delivering the experience to the end users. This application layer is hosted on the Internet Computer blockchain and can be accessed on this link.

The entire application of EstateDAO is hosted on-chain, except the Know-your-Customer process. The microservices of EstateDAO comprises of the following:

1. Provision Canister:

The Main Canister is the primary canister responsible for managing the properties listed on EstateDao. The process involves:

Property owners fill out an application form to list their property for sale on EstateDao. Upon approval, the Main Canister provisions:

• An NFT Collection Canister (Minter Canister)
• An Asset Canister for storing property images and documents.

The Main Canister also manages commit permissions over the Asset Canister and provides filters for NFT collections.

1. Minter Canisters:

The Minter Canister adheres to the minimal ICRC7 standard and performs the following tasks:

• Creates and manages collection data for the property.
• Mints NFTs for the property.
• Facilitates primary sales of the NFTs.
• Manages an escrow account for each user to hold primary sale funds until completion of the sale.

1. Asset Canisters: An Asset Canister on ICP is a specialized smart contract used for storing and managing digital assets. In Estate, the Asset Canister is utilized to store property images and required documents for each property.
