Design and implement Permission/interop system

[thiscaspar]

Description:

We aim to design a blockchain-based system that defines the behavior of a pixel when another pixel interacts with it. This permission and interoperability system will be crucial for managing interactions between pixels in our platform.

System Process:

1. Pixel Interaction: When a pixel interacts with another pixel, the system checks the permissions associated with the target pixel on the blockchain.
2. Permission Check: The system determines whether the interaction is allowed based on the permissions set for the target pixel in the blockchain.
3. Interaction Outcome: If the interaction is permitted, the system executes the interaction and updates the state of the pixels accordingly on the blockchain.

Requirements:

1. Blockchain Smart Contract: Develop a smart contract for setting and checking permissions for each pixel. This should include a way to specify which types of interactions are allowed for each pixel.
2. Interoperability System: Design a system that handles interactions between pixels. This should include a way to execute interactions and update pixel states on the blockchain.
3. Front-End Interface: Create an interface for users to set permissions for their pixels and initiate interactions with other pixels.
4. Testing: Thoroughly test the system to ensure it works correctly and securely.

Deliverables:

1. A fully functioning blockchain-based permission and interoperability system for pixel interactions.
2. Comprehensive documentation explaining how the system works and how to use it.
3. Test cases and their results.
