About

Honeypot is an application-specific rollup designed to challenge the security of Cartesi Rollups. It provides a gamified battlefield to incentivize bug hunters to hack the application to obtain the funds locked in the rollup contract.

    The project will be classified as "Other" due to its specific risks that set it apart from the standard classifications.

    The project will move to Others because:

    The proof system isn't fully functional

    Consequence: projects without a proper proof system fully rely on single entities to safely update the state. A malicious proposer can finalize an invalid state, which can cause loss of funds.

    Risk summary

    Funds can be frozen if

    1. the centralized validator goes down. Users cannot produce blocks themselves and exiting the system requires new block production (CRITICAL).

    MEV can be extracted if

    1. the operator exploits their centralized position and frontruns user transactions.
    Risk analysis
    Sequencer failureState validationData availabilityExit windowProposer failure
    Sequencer failure
    Self sequence

    In the event of a sequencer failure, users can force transactions to be included in the project’s chain by sending them to L1. There is no delay on this operation.

    State validation
    None

    Currently the system permits invalid state roots. More details in project overview.

    Data availability
    Onchain

    All of the data needed for proof construction is published on Ethereum L1.

    Exit window
    ∞

    Users can exit funds at any time because contracts are not upgradeable.

    Proposer failure
    Cannot withdraw

    Only the whitelisted proposers can publish state roots on L1, so in the event of failure the withdrawals are frozen.

    Please keep in mind that these stages do not reflect rollup security, this is an opinionated assessment of rollup maturity based on subjective criteria, created with a goal of incentivizing projects to push toward better decentralization. Each team may have taken different paths to achieve this goal.
    Technology

    Fraud proofs are in development

    Ultimately, Cartesi DApps will use interactive fraud proofs to enforce state correctness. This feature is currently in development and the Honeypot DApp permits invalid state roots. Since Honeypot is immutable, this feature will not be added to the DApp.

    • Funds can be stolen if an invalid state root is submitted to the system by the configured Authority (CRITICAL).

    1. Authority.sol#L148 - Etherscan source code, submitClaim function
    Data availability

    All transaction data is recorded on chain

    All executed transactions are submitted to an on chain smart contract. The execution of the rollup is based entirely on the submitted transactions, so anyone monitoring the contract can know the correct state of the rollup chain.

    State derivation
    Node software

    The Cartesi node software source code can be found here.

    Compression scheme

    No compression is used.

    Genesis state

    The genesis state is derived from the Honeypot Cartesi Machine template, which can be found within the Honeypot server Docker image at /var/opt/cartesi/machine-snapshots/0_0. Alternatively, it is possible to recreate it by following the build procedure outlined in the Honeypot GitHub Repository.

    Data format

    The reference implementation for ERC20 deposits can be found here. To learn about the withdrawal request format, please refer to the documentation here.

    Operator

    The system has a centralized operator

    The operator is the only entity that can propose blocks. A live and trustworthy operator is vital to the health of the system.

    • MEV can be extracted if the operator exploits their centralized position and frontruns user transactions.

    Users can force any transaction

    Because the state of the system is based on transactions submitted on the underlying host chain and anyone can submit their transactions there it allows the users to circumvent censorship by interacting with the smart contract on the host chain directly.

    Withdrawals

    Regular exit

    The user initiates the withdrawal by submitting a regular transaction on this chain. When the block containing that transaction is settled the funds become available for withdrawal on L1. The process of settling a block usually takes several days to complete. Finally the user submits an L1 transaction to claim the funds.

    • Funds can be frozen if the centralized validator goes down. Users cannot produce blocks themselves and exiting the system requires new block production (CRITICAL).
