High Level Overview of Boost V2

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.
Boost Signature Flow
  1. 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.
  2. 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.
