Sentium EVM

Quantum-Resistant EVM Compatibility Layer

Overview

Sentium EVM is a standalone EVM (Ethereum Virtual Machine) compatibility layer that enables Solidity smart contracts to run on Sentium-based blockchains. Similar to Cosmos Ethermint, it provides full Ethereum compatibility while adding quantum-resistant security features.

Why Separate Repository?

• ✅ Optional feature (not all Sentium chains need EVM)
• ✅ Different team (Ethereum/Solidity developers focused)
• ✅ Independent versioning
• ✅ Ethereum ecosystem integration
• ✅ Focused security audits for EVM-specific vulnerabilities

Features

• Full EVM Compatibility: Run existing Solidity contracts without modification
• Quantum-Resistant Opcodes: New opcodes for post-quantum cryptography
• EVM-to-Quantum VM Bridge: Seamless interoperability
• Ethereum Bridge Contracts: Connect to Ethereum mainnet
• Gas Optimization: Improved gas metering for quantum operations

New Quantum-Safe Opcodes

Opcode	Name	Description
0xF0	QSIGN	Dilithium5 signature
0xF1	QVERIFY	Verify quantum signature
0xF2	QENCRYPT	Kyber1024 encryption
0xF3	QDECRYPT	Kyber1024 decryption
0xF4	QHASH	SHA3-512 hashing

Installation

# Add to Cargo.toml
sentium-evm = "0.1"

# Or install CLI tools
cargo install sentium-evm-cli

Quick Start

Deploy Solidity Contract

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;

contract QuantumSafe {
    // Use quantum-safe signature verification
    function verifyQuantumSignature(
        bytes memory message,
        bytes memory signature,
        bytes memory publicKey
    ) public pure returns (bool) {
        // New QVERIFY opcode
        assembly {
            let result := qverify(message, signature, publicKey)
            mstore(0x00, result)
            return(0x00, 32)
        }
    }
}

Rust Integration

use sentium_evm::{EVM, Contract};

// Create EVM instance
let evm = EVM::new()
    .with_quantum_opcodes()
    .build();

// Deploy contract
let contract = Contract::from_solidity("MyContract.sol")?;
let address = evm.deploy(contract).await?;

// Call contract
let result = evm.call(address, "myFunction", &[]).await?;
