Milestone: PoA & VM Execution
Overview
This milestone focuses on implementing Proof of Authority (PoA) consensus and Virtual Machine (VM) execution for OPNet, enhancing the Bitcoin Layer 1 with smart contract capabilities. This milestone will also include the integration of WBTC (Wrapped Bitcoin) swapping functionalities and p2p trading.
Objectives
-
PoA Consensus Implementation
- Develop and integrate a robust PoA consensus mechanism.
- Establish a set of validators authorized to validate transactions.
- Implement a reward system for validators.
- Ensure secure and efficient validation processes.
-
VM Execution
- Develop a Virtual Machine (VM) for executing smart contracts.
- Ensure deterministic execution of contracts to prevent variances in contract outcomes.
- Implement isolation mechanisms using isolated-vm to sandbox contract execution.
- Introduce a timeout mechanism based on CPU cycles to prevent DoS attacks and infinite loops.
-
WBTC Swapping Integration (PSBT) / P2P trading style (PSBT)
- P2P trading style
- Implement functionalities for swapping BTC to WBTC and vice versa.
- Ensure 1:1 value correspondence between BTC and WBTC.
- Integrate smart contract mechanisms for secure and transparent swaps.
Detailed Tasks
PoA Consensus Implementation
-
Validator Selection and Management
- Define criteria for selecting validators.
- Develop smart contracts for validator registration and management.
- Implement a mechanism to regularly update the list of active validators.
-
Transaction Validation
- Develop algorithms for transaction validation.
- Ensure transactions are validated efficiently and securely.
- Implement consensus rules and ensure compliance among validators.
-
Reward System
- Develop a reward system to incentivize validators.
- Implement smart contracts for distributing rewards.
- Ensure transparency and fairness in reward distribution.
VM Execution
-
VM Development
- Design and develop a VM capable of executing WebAssembly (Wasm) based contracts.
- Ensure compatibility with OP20 and other relevant standards.
- Implement a deterministic execution environment.
-
Isolation and Security
- Use isolated-vm to create isolated execution contexts for each contract.
- Implement security measures to prevent cross-contract interference.
- Ensure robust handling of external calls and state changes.
-
Timeout Mechanism
- Develop a timeout mechanism based on CPU cycles to limit execution time.
- Implement monitoring and enforcement of execution limits.
- Ensure graceful termination of contracts exceeding execution limits.
WBTC Swapping Integration (PSBT) / P2P trading style (PSBT)
-
Swap Mechanism Development
- Develop smart contracts for BTC to WBTC swaps and vice versa.
- Ensure atomic swaps to guarantee 1:1 value correspondence.
- Implement mechanisms to handle edge cases and failures securely.
-
Testing and Security
- Conduct thorough testing of the swap mechanism under various scenarios.
- Implement security audits to identify and mitigate vulnerabilities.
- Ensure compliance with industry standards and best practices.
Deliverables
- Fully implemented PoA consensus mechanism.
- Operational VM for executing Wasm-based smart contracts. (rust)
- Integrated WBTC swapping functionalities.
- Documentation detailing the implementation, usage, and maintenance.
- Comprehensive test cases and results.

- Ensure libraries provide a simple and intuitive interface for interacting with the JSON-RPC server.
-
Documentation and Examples
- Provide comprehensive documentation for each client library.
- Include usage examples and sample code to help developers get started quickly.
-
Community Engagement
- Engage with the developer community to gather feedback and improve the libraries.
