Technical Plan and Architecture

BlockBunny's Cross-Chain Architecture

Interoperability: Our architecture ensures seamless communication between various blockchains by leveraging bridges, cross-chain communication protocols, oracles, and other interoperability solutions. We also utilize the Farcaster protocol for enhanced cross-chain interactions and data integrity.

Smart Contracts: We develop smart contracts compatible across all targeted blockchains. This involves deploying separate contracts on each chain or using standardized cross-chain frameworks. Solidity is our primary language for writing these contracts, ensuring robust and secure code.

Multi-Chain Deployment

• Ethereum: BlockBunny uses Ethereum for its established ecosystem and strong smart contract capabilities. Ethereum's Solidity language is employed for developing smart contracts that handle NFT minting, transactions, and governance.

• Solana: To benefit from Solana's high throughput and low transaction costs, BlockBunny deploys additional smart contracts written in Rust or C. This ensures that users can perform high-speed transactions and interact with decentralized applications (dApps) seamlessly.

Off-Chain Architecture

• MERN Stack with Next.js: The off-chain components of BlockBunny are built using the MERN stack (MongoDB, Express.js, React, Node.js) along with Next.js for server-side rendering and improved performance.

  • MongoDB: A NoSQL database that handles the storage of user profiles, NFT metadata, transaction logs, and other non-blockchain data.

  • Express.js: A web application framework for Node.js, used to build the backend services and APIs that facilitate communication between the frontend and the blockchain.

  • React: A JavaScript library for building dynamic and responsive user interfaces, ensuring a smooth user experience.

  • Next.js: A React framework that provides server-side rendering, static site generation, and other advanced features to enhance performance and SEO.

  • Node.js: A runtime environment that executes JavaScript code on the server-side, powering the backend logic and integrating with blockchain networks.

Using Cross-Chain Tools and Protocols

Bridges: BlockBunny utilizes blockchain bridges to facilitate asset transfer and communication using Bunny Tokens across Ethereum, Polygon, and Solana. Key bridges include:

• Polygon Bridge: Connects Ethereum to Polygon.

• Wormhole: Supports decentralized bridging for Ethereum, Solana, and other chains.

Cross-Chain Protocols: We leverage protocols designed for multi-chain operations, such as:

• Polkadot: Renowned for its interoperability between different blockchains.

• Cosmos: Facilitates connections between various blockchain networks.

• Farcaster Protocol: Enhances our cross-chain data integrity and interaction capabilities.

• Lens Protocol

Deploying Smart Contracts on Multiple Chains

• Ethereum: We use Solidity to write and deploy smart contracts on the Ethereum network for Bunny Tokens.

• Polygon: Our Ethereum smart contracts are deployed on Polygon with minor adjustments due to its EVM compatibility.

• Solana: We develop and deploy programs (smart contracts) on the Solana network using Rust or C for Bunny Tokens.

Utilizing Multi-Chain Development Frameworks

• Foundry: We utilize the Foundry framework for developing, testing, and deploying Bunny Token smart contracts across EVM-compatible chains like Ethereum and Polygon.

• Anchor: Used for Solana smart contract development.

• Thirdweb: Provides tools and SDKs for deploying and managing multi-chain applications.

Implementing Cross-Chain Data Storage and Management

• Oracles: We use decentralized oracle services like Chainlink to fetch and verify data across different blockchains for Bunny Token transactions.

• Decentralized Storage: IPFS or Filecoin is considered for storing data in a decentralized manner, accessible from multiple chains.

Integrating Wallets and User Interfaces

• Wallet Compatibility: BlockBunny ensures platform support for wallets that operate across multiple chains (e.g., MetaMask, Phantom) for holding Bunny Tokens.

• Unified Interface: We develop a user interface that seamlessly interacts with multiple chains, detecting the user’s current network and providing appropriate options.

Ensuring Security and Audits

• Security Audits: BlockBunny conducts thorough security audits for Bunny Token smart contracts on all networks.

• Cross-Chain Security: We implement measures to protect against cross-chain vulnerabilities, such as replay attacks or bridge exploits.

Leveraging Cross-Chain SDKs and APIs

• Web3.js/Ethers.js: For interacting with Ethereum and Polygon using Bunny Tokens.

• Solana Web3.js: For interacting with the Solana network using Bunny Tokens.

• Third-Party SDKs: BlockBunny explores SDKs from third-party services that provide cross-chain functionalities.

Community and Ecosystem Engagement

Developer Communities: We engage with developer communities and resources on Ethereum, Polygon, and Solana to stay updated on best practices and emerging technologies.

Ecosystem Grants: BlockBunny applies for grants and support from ecosystem foundations like the Ethereum Foundation, Polygon Grants, and Solana Foundation.

Testing and Iteration

Testnets: Our platform is deployed and tested on testnets (Sepolia or Goerli for Ethereum, Mumbai for Polygon, Solana Devnet) using Bunny Tokens before going live.

Continuous Improvement: We iterate based on user feedback and emerging technologies to continually improve our platform.
