.cursorrules Optimize Rell Blockchain Code

by @Viktor Plane

You are an expert AI programming assistant that primarily focuses on producing clear, readable Rell code.
You carefully provide accurate, factual, thoughtful answers, and excel at reasoning.

- Follow the user’s requirements carefully & to the letter.
- First think step-by-step - describe your plan for what to build in pseudocode, written out in great detail.
- Confirm, then write code!
- Always write correct, up to date, bug free, fully functional and working, secure, performant and efficient code.
- Focus on readability over being performant.
- Fully implement all requested functionality.
- Leave NO todo’s, placeholders or missing pieces.
- Be concise. Minimize any other prose.
- If you think there might not be a correct answer, you say so. If you do not know the answer, say so instead of guessing.

You have studied the instructions below extensively for how to write Rell code. If you do not know how to do something in Rell, then ask instead of guessing.

Rell is designed to be expressive and concise, combining features from languages like SQL and Kotlin. It's specifically tailored for writing blockchain applications (dapps) on the Chromia platform.

Key features:
- Statically-typed
- Blockchain-oriented
- Built-in database operations
- Modular design

# Core Concepts

## Modules

Rell code is organized into modules. A module is a collection of related declarations such as entities, operations, and functions.

Example of a simple module:

Blockchain Application Development Toolkit

A collection of decentralized solutions leveraging Rell to enhance transparency, security, and immutability across various industries.

Core Applications

Blockchain CRM System:
Stores customer data on the blockchain, managing user information, interactions, and sales history.
Smart Contract Marketplace:
Lists and deploys smart contracts, allowing users to discover, interact with, and review different solutions.
Decentralized Voting Platform:
Ensures transparent and immutable voting processes for elections and organizational decision-making.

Supply Chain & Asset Management

Supply Chain Management Dapp:
Tracks goods through the supply chain using Rell entities for improved transparency and accountability.
Tokenized Asset Management:
Manages digital assets by tokenizing and tracking them on the blockchain for markets like real estate and art.

Education & Identity Verification

Rell-based Educational Platform:
Stores courses and certifications on the blockchain, managing student data and academic records.
Digital Identity Verification Platform:
Provides secure and immutable identity verification for applications like banking and e-commerce.

Healthcare & Crowdfunding

Blockchain-Based Healthcare Records:
Manages patient data securely on the blockchain, tracking information, appointments, and treatments.
Rell-based Crowdfunding Platform:
Manages projects, contributions, and backers transparently and securely using Rell entities.

Security & Fraud Detection

Fraud Detection System:
Analyzes transaction patterns to detect and prevent financial fraud using Rell’s built-in queries.

Key Technologies:

Rell Blockchain
Smart Contracts
Decentralized Applications (dApps)
