Feature | Substrate Account | EVM-Compatible Account | Potential Conflicts |
---|---|---|---|
Underlying Technology | Customizable blockchain framework. | Runs Ethereum smart contracts; uses Ethereum tools. | Different base technologies limit direct interoperability. |
Account Format | Uses public-private key pair, SS58 address format. | Hexadecimal address format derived from public key. | Incompatible address formats can complicate cross-platform interactions. |
Compatibility | Customizable, can integrate EVM if configured. | Directly compatible with Ethereum and its dApps. | Default configurations may not support cross-chain functionality without modifications. |
Functionality and Use | Highly customizable, supports governance, staking. | Focused on smart contracts and dApps. | Substrate's broader functionality may not be fully utilizable in EVM without specific adjustments. |
Security and Network | Additional security features can be designed. | Depends on Ethereum's security and features. | Security assumptions and features may differ, requiring careful integration planning. |
Issue Category | Description | Impact on Integration |
---|---|---|
Gas and Fee Mechanisms | Substrate uses flexible, customizable fee structures, different from the EVM's gas-based model. | Confusion and incompatibility in transaction fees leading to potential execution issues. |
Consensus Mechanisms | Substrate supports various consensus mechanisms, which may not align with those used by EVM. | Affects block validation and network security; requires alignment for proper functionality. |
Storage and State Management | Substrate and EVM manage storage and state differently, potentially causing inefficiencies or data loss. | Challenges in data management that could impact application performance and state consistency. |
Event Handling and Logging | Different systems for events and logs can impact how dApps function and interact. | Ensuring consistent and accurate event logging and handling across both platforms is crucial. |
Tooling and Developer Experience | Differences in development tools, languages, and environments between Substrate (Rust) and EVM (Solidity). | Learning curve and potential for bugs due to tool adaptation issues. |
Upgradeability and Governance | Discrepancies in how Substrate and EVM handle upgrades and governance. | Possible governance conflicts and upgrade incompatibilities. |
Inter-Contract Communication | Communication between Substrate and EVM contracts may require special protocols or bridges. | Adds complexity and potential failure points in contract interactions. |
