Execution Layer

Introduction

The DaVinci Chain Execution Layer is responsible for processing transactions, executing smart contracts, and maintaining the state of the blockchain. As a fully DaVinci Virtual Machine (DVM) Layer 1 blockchain, DaVinci Chain follows the same execution model as Ethereum, ensuring compatibility with existing Ethereum-based tools and applications.

Overview of the Execution Layer

The Execution Layer is a crucial component of DaVinci Chain, responsible for handling:

• Transaction Processing – Validating and executing user transactions.

• Smart Contract Execution – Running decentralized applications (dApps) and executing Solidity-based smart contracts.

• State Management – Updating account balances, contract storage, and network state after transaction execution.

• EVM Compatibility – Ensuring seamless interaction with Ethereum-based wallets, tools, and protocols.

Core Components of the Execution Layer

1. DaVinci Virtual Machine (DVM)

   • Executes smart contracts and processes transactions within the DaVinci Chain network.

   • Fully compatible with Solidity, Vyper, and other Ethereum-based development languages.

2. Transactions & Gas Fees

   • Transactions require gas fees, similar to Ethereum, to prevent spam and allocate network resources efficiently.

   • Gas fees are paid in the native token of DaVinci Chain.

3. Smart Contract Execution

   • Developers can deploy and interact with smart contracts using Ethereum-standard tools like Remix, Hardhat, Truffle, and Web3.js.

   • Supports ERC-20, ERC-721, and other Ethereum token standards.

4. State Management

   • The Execution Layer updates the blockchain state by processing transactions and storing contract states.

   • Utilizes Merkle Patricia Tries for efficient storage and retrieval of account data.

5. Interoperability

   • DaVinci Chain’s Execution Layer is designed for seamless integration with existing Ethereum infrastructure.

   • Supports Ethereum’s JSON-RPC API, allowing easy interaction with wallets like Metamask, Trust Wallet, and other.

How the Execution Layer Works

1. Transaction Submission – Users submit transactions through wallets or dApps.

2. Transaction Validation – Transactions are verified by the network’s nodes.

3. Execution in the EVM – The smart contract code is executed within the EVM environment.

4. State Update – The blockchain state is updated based on the execution results.

5. Block Finalization – Valid transactions are added to new blocks and propagated across the network.

Developer Tools & Integration

To build on DaVinci Chain, developers can use:

• Solidity & Vyper for smart contract development.

• Truffle & Hardhat for contract deployment and testing.

• Web3.js & Ethers.js for blockchain interactions.

• Metamask & WalletConnect for user authentication and transactions.
