Introduction
On May 13th at 15:00 Beijing Time, BOSCore's core developers hosted an ecosystem discussion titled "How to Run Ethereum Smart Contracts on the EOS Network?" This session featured insights from Deadlock, a renowned blockchain architect and BOSCore's lead developer, who specializes in EOSIO底层架构 and cross-chain technologies. Below is a refined transcript of the key Q&A.
Key Concepts Explained
Q1: What is EOS-EVM?
A1:
EOS-EVM enables developers to execute Ethereum Solidity smart contracts within EOSIO’s environment. Think of it as a compatibility layer that translates Ethereum Virtual Machine (EVM) bytecode into EOS-executable logic.
Q2: How Does EVM Work on EOS?
A2:
EOS-EVM mimics EVM logic via EOS smart contracts, adhering to Ethereum’s specifications while leveraging EOS features like CPU/NET resource management.

Analogy:
"Running EVM on EOS is like playing Windows games on a Mac via a virtual machine—EOS is the Mac, EVM the虚拟机, and the game is the smart contract."
Q3: Differences Between EOS-EVM and Ethereum EVM?
A3:
- No Gas Fees: EOS-EVM waives Gas charges (Gasprice = 0, Difficulty = 0) but retains Gas calculation logic for optional activation.
- Resource Model: Uses EOS’s质押-based CPU/NET instead of ETH’s Gas-for-block-space approach.
Q4: Why Join the EOSIO Challenge?
A4:
- Technical Preparedness: BOSCore’s existing IBC跨链 expertise made the challenge feasible.
- Vision Alignment: Matches BOSCore’s goal of a "blockchain freeport" via BOS IBC HUB.
- Community Engagement: Showcases commitment to developer-friendly innovation.
Technical Deep Dive
Q5: Gas Fundamentals
Definitions:
| Term | Description |
|-------------|--------------------------------------------|
| Gas | Unit for measuring computational effort. |
| GasLimit| Max Gas a user allocates per transaction. |
| GasPrice| Price per Gas unit (denominated in Gwei). |
Relationship:
"GasFee = Gas × GasPrice (like fuel cost = liters × price per liter)."
Q6: Transaction Execution
- CPU/NET Costs: EOS mandates these instead of Gas fees.
- Speed Impact: EVM simulation adds complexity but doesn’t slow block confirmation.
Q7: RPC Compatibility
EOS-EVM supports core Ethereum RPCs (e.g., getBalance) but omits irrelevant features (e.g., hashrate). Custom solutions like the simulate interface enable off-chain queries.
Challenges and Solutions
Q8: Security Concerns
A8:
EOS-EVM maintains Ethereum’s security level since:
- It’s an EOS smart contract with EVM-equivalent logic.
- No VM-layer modifications risk链 integrity.
Q9: Enterprise Use Cases
Options for私有数据:
- 联盟链: Restricted access among trusted parties.
- 公链 + Encryption: Leverage immutability selectively.
Q10: Transaction Timeouts
EOS’s 30ms default transaction limit may cause ETH合约 failures. Workarounds involve optimizing contract logic (e.g., splitting lengthy operations).
FAQ
Q: Can EOS-EVM attract Ethereum developers?
A: Yes! It bridges ecosystems, enabling "code once, deploy multichain" strategies.
Q: How does跨合约调用 work?
A: EVM contracts interact via internal transactions, similar to Ethereum’s model.
Q: What’s next for BOSCore?
A: Enhancing EVM2.0 compatibility and expanding cross-chain interoperability.
Conclusion
EOS-EVM unlocks multi-chain flexibility by merging Ethereum’s developer ecosystem with EOS’s performance. While challenges like transaction limits exist, its potential for cross-chain collaboration makes it a groundbreaking innovation.
