Architecture & Technology Stack
Graso’s architecture is built on Starknet, a high-performance Layer 2 ZK-Rollup network on Ethereum, offering scalability, low transaction costs, and strong security guarantees. By leveraging Starknet's Cairo programming language and its innovative zero-knowledge proof infrastructure, Graso provides a seamless and secure experience for investors, developers, and property owners in the real estate sector.
1. Blockchain Layer: Starknet Ecosystem
The Starknet blockchain, developed by StarkWare, provides Graso with significant advantages:
Scalability: Starknet enables off-chain computation with on-chain verification through STARK proofs, allowing Graso to scale seamlessly while maintaining Ethereum-grade security. This is essential for handling high-volume transactions involving fractional ownership, property tokenization, and marketplace trading.
Low Transaction Costs: By batching transactions and settling them on Ethereum, Starknet drastically reduces transaction fees, making micro-investments and regular rental income distributions cost-effective.
Cairo Programming Language: Graso utilizes Cairo, Starknet's native programming language, to build modular, verifiable smart contracts. These contracts govern tokenization, crowdfunding, fractional ownership, and rental income distribution.
ZK-Rollup Security: Starknet inherits Ethereum's security through its zero-knowledge rollup mechanism, ensuring the integrity and immutability of all transactions on Graso.
2. Key Components
Graso's architecture comprises modular, decentralized components for performance, transparency, and reliability:
Smart Contracts (Cairo-based)
Property Tokenization: Smart contracts will tokenize physical properties into digital assets, each represented by unique tokens that can be fractionally owned, traded, and rented.
Crowdfunding Contracts: Real estate developers can raise capital via decentralized crowdfunding. Investors contribute funds in return for tokens that represent ownership rights or revenue shares.
Rental Income Distribution: These contracts automate the distribution of rental income to token holders, ensuring accurate, transparent, and timely payouts.
DeFi Integration
Staking & Yield Farming: Users can stake Graso’s native token (GRA) within liquidity pools on Starknet. Rewards incentivize participation and liquidity provision.
Decentralized Exchange (DEX) Integration: Graso integrates with Starknet-based DEXs to support trading of property tokens, creating liquidity and enabling secondary market activity.
Crowdfunding Mechanism
Graso’s decentralized crowdfunding allows developers to raise funds for real estate projects from a broad pool of small and medium investors. Contributors receive tokenized ownership or revenue rights upon project completion.
NFTs for Property Titles
Each property will be represented by a Non-Fungible Token (NFT) that encodes ownership metadata, legal documents, and historical information. These NFTs are tradable and ensure legal transparency and traceability.
3. Frontend Technologies
Graso’s frontend ensures a modern, responsive experience using cutting-edge web technologies:
React.js: Used for building an interactive UI that enables seamless navigation and real-time interaction with property listings, tokenized assets, and investment dashboards.
Next.js: Offers server-side rendering and SEO optimization to improve user acquisition and discoverability.
Starknet.js: Enables wallet integration, contract interaction, and transaction management on Starknet directly from the frontend.
4. Backend Infrastructure
Graso’s backend manages off-chain operations and facilitates interaction with the Starknet blockchain:
Node.js & Express.js: Powers the API layer that connects frontend applications with smart contracts and databases.
Starknet Nodes: Graso will operate Starknet nodes to interface directly with the network, ensuring low-latency, real-time platform performance.
Database (MongoDB): Off-chain data such as user profiles, property metadata, and analytics will be stored in a NoSQL database, securely linked to on-chain activity.
5. Security Layer
Graso prioritizes robust security practices for its users and property data:
Contract Audits: All Cairo-based smart contracts will undergo independent audits to ensure security, correctness, and resistance to exploits.
Multi-Signature Wallets: Administrative functions and large-value transactions will be managed via multi-signature wallets to enhance operational security.
Data Encryption: Sensitive information like user identities, property documents, and investment logs will be encrypted both in transit and at rest.
KYC/AML Compliance: Integration with third-party KYC providers ensures that user verification aligns with global regulatory standards.
6. Decentralized Storage
Graso uses decentralized solutions to store and serve immutable data:
IPFS: Property contracts, legal documents, and media will be stored on the InterPlanetary File System (IPFS) to ensure transparency and permanence.
Arweave: Historical data such as transaction logs and ownership records will be archived permanently on Arweave for long-term accessibility.
7. Governance & Decentralization
Graso will transition towards decentralized governance to empower its community:
Governance Tokens (GRA): Token holders will vote on major decisions, including fee structures, platform upgrades, and community proposals.
DAO (Decentralized Autonomous Organization): Graso will evolve into a DAO that entrusts its stakeholders with controlling the platform’s development, treasury, and future direction.
Through this Starknet-based architecture, Graso combines blockchain innovation with user-friendly technology to create an open, secure, and efficient real estate investment ecosystem.
