    Risk summary

    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 can be up to a 7d delay on this operation. Proposing new blocks requires creating ZK proofs.

    State validation
    ZK proofs (SN)

    SNARKs are zero knowledge proofs that ensure state correctness, but require trusted setup.

    Data availability
    Onchain

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

    Exit window
    None

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

    Proposer failure
    Self propose

    If the Proposer fails, users can leverage the source available prover to submit proofs to the L1 bridge.

    Learn more about Rollup stages
    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.
    Data availability

    All data required for proofs is published on chain

    All the data that is used to construct the system state is published on chain in the form of cheap blobs or calldata. This ensures that it will be available for enough time.

    1. ScrollChain.sol - Etherscan source code commitBatch() and commitBatchWithBlobProof() functions
    Learn more about the DA layer here: Ethereum logoEthereum
    State derivation
    Node software

    The node software to reconstruct the state is available here. Note that it uses the L2 p2p network to fetch blocks, and not the L1 network. The consistency with L1 data can be checked by running the scroll-geth node with the --rollup.verify flag.

    Compression scheme

    Data batches are compressed using the zlib algorithm with best compression level.

    Genesis state

    The genesis file can be found here, which contains two prefunded addresses and five predeployed contracts.

    Data format

    Blocks are grouped into chunks, chunks are grouped into batches, and batches are grouped into bundles. Chunk encoding format can be found here, and batch encoding format can be found here.

    State validation

    Each update to the system state must be accompanied by a ZK proof that ensures that the new state was derived by correctly applying a series of valid user transactions to the previous state. These proofs are then verified on Ethereum by a smart contract.

    Prover Architecture

    The prover code can be found here.

    ZK Circuits

    Scroll circuits are openvm based Guest Programs based on the Halo2 proof system. The source code of the base circuits can be found here.

    Verification Keys Generation

    SNARK verification keys can be generated and checked against Ethereum verifier contract using this guide. The system requires a trusted setup.

    Validity proofs

    Each update to the system state must be accompanied by a ZK proof that ensures that the new state was derived by correctly applying a series of valid user transactions to the previous state. These proofs are then verified on Ethereum by a smart contract.

    1. ScrollChain.sol - Etherscan source code, verifyAggregateProof() and verifyBundleProof() calls
    Operator

    The system has a centralized sequencer

    While forcing transaction is open to anyone the system employs a privileged sequencer that has priority for submitting transaction batches and ordering transactions.

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

    1. ScrollChain.sol - Etherscan source code, finalizeBundlePostEuclidV2() function modifier

    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. The enforced liveness mechanism is activated if either an L1 message has not been finalized for more than 7d or a batch has not been finalized for more than 7d. When activated, transactions that were directly posted to the smart contract can be forcefully included by anyone on the host chain, which finalizes their ordering.

    2. L1MessageQueueV2 - Etherscan proxy contract
    Withdrawals

    Regular messaging

    The user initiates L2->L1 messages by submitting a regular transaction on this chain. When the block containing that transaction is settled, the message becomes available for processing on L1. ZK proofs are required to settle blocks.

    Upgrades & Governance
    A diagram of the upgrades and governance
    A diagram of the upgrades and governance

    All core contracts in the Scroll protocol are upgradable by the ProxyAdmin, which is controlled by the Security Council through the ScrollOwner contract. The ScrollOwner is a central governance contract controlled by four distinct Timelocks: two governed by the Security Council multisig and two by the Scroll team multisigs. Each multisig can initiate specific types of changes with differing delay guarantees. The team can change parameters that affect L1->L2 messaging and the activation of permissionless sequencing (i.e., enforcedBatchMode), such as by calling the updateMessageQueueParameters and updateEnforcedBatchParameters functions through the TimelockFast, or by pausing the EnforcedTXGateway through the TimelockEmergency. It also has authority to revert unfinalized batches and add or remove sequencers and provers while sequencing is in permissioned mode. As the ScrollOwner admin, the Security Council can revert the team actions by revoking the team roles in the ScrollOwner contract (through the TimelockSCSlow) and upgrading the affected contracts. SCR token holders perform onchain voting on governance proposal through the AgoraGovernor contract on L2. However, upgrades are not triggered automatically, the Security Council is in charge of executing upgrades.
