    Why is the project listed in others?

    There are less than 5 external actors that can submit challenges

    Consequence: projects without a sufficiently decentralized set of challengers rely on few entities to safely update the state. A small set of challengers can collude with the proposer to finalize an invalid state, which can cause loss of funds.

    Risk summary
    There are 3 additional risks coming from the host chain Arbitrum One logoArbitrum One
    Fraud proof system is fully deployed but is not yet permissionless as it requires Validators to be whitelisted.

    Funds can be stolen if

    1. a contract receives a malicious code upgrade. There is no delay on code upgrades (CRITICAL),
    2. none of the whitelisted verifiers checks the published state. Fraud proofs assume at least one honest and able validator (CRITICAL).

    Funds can be lost if

    1. the sequencer posts an unavailable transaction root (CRITICAL),
    2. the data is not available on the external provider (CRITICAL),
    3. the external data becomes unavailable (CRITICAL).

    Users can be censored if

    1. the committee restricts their access to the external data.

    MEV can be extracted if

    1. the operator exploits their centralized position and frontruns user transactions.

    Withdrawals can be delayed if

    1. the owner of EspressoTEEVerifier updates the contract verification values (enclave hash, signer) and it is no longer possible to verify the TEE quote.
    Risk analysis
    The L3 risks depend on the individual properties of L3 and those of the host chain combined.

    L3 combined risks
    The information below reflects combined L2 & L3 risks.
    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 can be up to a 2d delay on this operation.

    State validation
    Fraud proofs (INT)

    No actor outside of the single Proposer can submit fraud proofs. Interactive proofs (INT) require multiple transactions over time to resolve. The challenge protocol can be subject to delay attacks. There is a 6d 8h challenge period.

    Data availability
    External (DAC)

    Proof construction relies fully on data that is NOT published onchain. There exists a Data Availability Committee (DAC) with a threshold of 1/1 that is tasked with protecting and supplying the data.

    Exit window
    None

    There is no window for users to exit in case of an unwanted upgrade since contracts are instantly upgradable.

    Proposer failure
    Self propose

    Anyone can become a Proposer after 12d 17h of inactivity from the currently whitelisted Proposers.

    Stage
    RARI Chain
    RARI Chain is not even a
    Stage 0
    project.
    The requirement for available node software is under review.
    Learn more about Stages
    Please keep in mind that these stages do not reflect project security, this is an opinionated assessment of project 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.
    Data availability

    Set of parties responsible for signing and attesting to the availability of data.

    Risk analysis
    Economic security
    None

    There are no onchain assets at risk of being slashed in case of a data withholding attack, and the committee members are not publicly known.

    Fraud detection
    None

    There is no fraud detection mechanism in place. A data withholding attack can only be detected by nodes downloading the full data from the DA layer.

    Committee security
    1/1

    The committee does not meet basic security standards, either due to insufficient size, lack of member diversity, or poorly defined threshold parameters. The system lacks an effective DA bridge and it is reliant on the assumption of an honest sequencer, creating significant risks to data integrity and availability.

    Upgradeability
    No delay

    There is no delay in the upgradeability of the bridge. Users have no time to exit the system before the bridge implementation update is completed.

    Relayer failure
    No mechanism

    The relayer role is permissioned, and the DA bridge does not have a Security Council or a governance mechanism to propose new relayers. In case of relayer failure, the DA bridge will halt and be unable to recover without the intervention of a centralized entity.
