Boost V2 Core Protocol Architecture

The Boost V2 core protocol architecture is designed to enable flexible, secure, and efficient on-chain incentivization. It consists of several key components that work together to validate actions, generate proofs, and distribute rewards. Here’s a breakdown of the architecture:

​

Components

• User: The end-user interacting with the system.
• ExternalContract: The smart contract with which the user interacts to perform the incentivized action.
• BackendValidator: An off-chain component that validates the user’s action.
• Core: The central smart contract of the Boost protocol.
• SignerValidator: An on-chain component that verifies the proof of the user’s action.

​

Process Flow

1. Action Execution:

   • The User executes an action on the ExternalContract.
   • This action is the behavior that Boost aims to incentivize.

2. Off-chain Validation:

   • The BackendValidator observes and validates the action off-chain.
   • This allows for complex validation logic without incurring high gas costs.

3. Signature Generation:

   • Upon successful validation, the BackendValidator generates a cryptographic signature.
   • This signature serves as a proof that the user performed the specified action.

4. Signature Submission:

   • The User submits the signature to the Core contract.
   • This step initiates the on-chain portion of the claiming process.

5. On-chain Verification:

   • The Core contract calls the SignerValidator with the provided signature.
   • The SignerValidator uses EIP-712 signature validation to verify the proof.
   • EIP-712 provides a secure method for signing and verifying structured data.

6. Reward Distribution:

   • If the signature is valid, the Core contract distributes the incentive to the User.

Choosing a Reward

When setting up a Boost, it’s crucial to choose an appropriate reward structure that aligns with your project’s goals and tokenomics. Here are some considerations:

1. Token Type:

   • Native tokens (e.g., ETH)
   • Project-specific tokens
   • Stablecoins (e.g., USDC, DAI)

2. Reward Amount:

   • Fixed amount per action
   • Percentage-based rewards
   • Tiered rewards based on action value or user status

3. Reward Frequency:

   • Immediate distribution upon action completion
   • Periodic distributions (e.g., daily, weekly)
   • Milestone-based rewards

4. Reward Caps:

   • Per-user caps to prevent exploitation
   • Total reward caps for budget control
   • Time-based caps (e.g., daily limits)

5. Vesting or Lock-up Periods:

   • Immediate availability
   • Gradual vesting to encourage long-term engagement
   • Lock-up periods for larger rewards

When choosing a reward structure, consider factors such as:

• The perceived value of the incentivized action
• Your project’s token supply and inflation rate
• User behavior and motivation
• Regulatory compliance and tax implications

A well-designed reward structure can effectively drive desired user actions while maintaining the economic balance of your ecosystem.

Key Improvements in V2

• Flexibility: The architecture allows for incentivizing actions on any external contract, greatly expanding the use cases for Boost.
• Gas Efficiency: By moving complex validation off-chain and only verifying a compact signature on-chain, gas costs are significantly reduced.
• Security: The use of EIP-712 for structured data signing ensures that the proofs are secure and tamper-resistant.
• Scalability: The off-chain validation allows for handling complex conditions and high volumes of actions without congesting the blockchain.
• Modularity: The separation of concerns between different components (ExternalContract, BackendValidator, Core, SignerValidator) allows for easier upgrades and maintenance.
