# Molten Network Markdown version of https://ethbeat.org/layer2s/projects/molten ## Summary **Warning:** This project is archived and no longer maintained. **Warning:** Critical contracts can be upgraded by an EOA which could result in the loss of all funds. **Warning:** 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.

Molten adds the Espresso TEE sequencer to their Celestia DA with Blobstream. - 2024-11-13: [Molten starts using Blobstream](https://arbiscan.io/tx/0x9a8ae683e857b80a843f7f071b0f831ac8162c6ac2c09fd9a8a514809d80c7af). Upgraded ChallengeManager contract to the version that uses Celestia with Blobstream bridge. - 2024-03-31: [Mainnet Launch](https://x.com/MoltenL3/status/1774485708742205545). Molten launches its Mainnet. ## Risk summary There are 3 additional risks coming from the host chain [Arbitrum One](https://ethbeat.org/layer2s/projects/arbitrum) **Warning:** 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). ### MEV can be extracted if 3. the operator exploits their centralized position and frontruns user transactions. ### Withdrawals can be delayed if 4. 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. **Warning:** Critical contracts can be upgraded by an EOA which could result in the loss of all funds. **Warning:** Fraud proof system is fully deployed but is not yet permissionless as it requires Validators to be whitelisted. | | Sequencer failure | State validation | Data availability | Exit window | Proposer failure | | --- | --- | --- | --- | --- | --- | | Arbitrum One (L2) | Self sequence (sentiment: good) | Fraud proofs (INT) (sentiment: good) | Onchain (sentiment: good) | None (sentiment: bad) | Self propose (sentiment: good) | | Molten Network (L3, individual) | Self sequence (sentiment: good) | Fraud proofs (INT) (sentiment: bad) | Onchain (sentiment: good) | None (sentiment: bad) | Self propose (sentiment: good) | | Molten Network (L3, combined) | Self sequence (sentiment: good) | Fraud proofs (INT) (sentiment: bad) | Onchain (sentiment: good) | None (sentiment: bad) | Self propose (sentiment: good) | ### L3 combined risks The information below reflects combined L2 & L3 risks. #### Sequencer failure Self sequence (sentiment: good) 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) (6d 8h challenge period; sentiment: bad) 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 Onchain (sentiment: good) All of the data needed for proof construction is published on Ethereum L1. #### Exit window None (sentiment: bad) There is no window for users to exit in case of an unwanted upgrade since contracts are instantly upgradable. #### Proposer failure Self propose (sentiment: good) Anyone can become a Proposer after 12d 17h of inactivity from the currently whitelisted Proposers. ## Stage Molten Network is not even a Stage 0 project. **The project does not pass the walkaway test**: users are not able to exit in the presence of malicious operators if the Security Council disappears. ### Stage 0 1 issue needs fixing. - Met: A complete and functional proof system is deployed. - Met: The project calls itself a rollup. - Met: State roots are posted to Ethereum L1. - Met: Inputs for the state transition function are posted to Ethereum L1. - Met: A source-available node exists that can recreate the state from Ethereum L1 data. Please note that the ETHBEAT team has not verified the validity of the node source code. [View code](https://github.com/OffchainLabs/nitro/) - Issue: Fraud proof submission is not sufficiently decentralized. ### Stage 1 3 issues need fixing. **Principle** - Issue: Compromising ≥75% of the Security Council should be the only way (other than bugs) for a rollup to indefinitely block an L2→L1 message (e.g. a withdrawal) or push an invalid L2→L1 message (e.g. an invalid withdrawal) with a <7d exit window. **Guidelines** - Met: Users are able to exit without the help of the permissioned operators. - Met: The sources of all programs used are public and program hashes can be independently regenerated. - Issue: Upgrades executed by actors with more centralized control than a Security Council provide less than 7d for users to exit if the permissioned operator is down or censoring. - Issue: The Security Council is not properly set up. ### Stage 2 3 issues need fixing. - Issue: Fraud proof submission is open only to whitelisted actors. - Issue: Upgrades unrelated to onchain provable bugs provide less than 30d to exit. - Issue: The Security Council's actions are not confined to onchain provable bugs. [Learn more about Stages](https://ethbeat.org/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 ### 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. **References** - [Sequencing followed by deterministic execution - Arbitrum documentation](https://developer.offchainlabs.com/inside-arbitrum-nitro/#sequencing-followed-by-deterministic-execution) - [SequencerInbox.sol - source code, addSequencerL2BatchFromOrigin function](https://arbiscan.io/address/0x481863c96f949F5E13932ec2F65470C0CF83808d#code) Learn more about the DA layer here: [Ethereum](https://ethbeat.org/projects/ethereum) ## State validation ![A diagram of the state validation](https://ethbeat.org/static/images/state-validation/orbit.b691a319.png) Updates to the system state can be proposed and challenged by a set of whitelisted validators. If a state root passes the challenge period, it is optimistically considered correct and made actionable for withdrawals. ### State root proposals Whitelisted validators propose state roots as children of a previous state root. A state root can have multiple conflicting children. This structure forms a graph, and therefore, in the contracts, state roots are referred to as nodes. Each proposal requires a stake, currently set to 0.1 ETH, that can be slashed if the proposal is proven incorrect via a fraud proof. Stakes can be moved from one node to one of its children, either by calling `stakeOnExistingNode` or `stakeOnNewNode`. New nodes cannot be created faster than the minimum assertion period by the same validator, currently set to 15m. The oldest unconfirmed node can be confirmed if the challenge period has passed and there are no siblings, and rejected if the parent is not a confirmed node or if the challenge period has passed and no one is staked on it. **Risks** - Funds can be stolen if none of the whitelisted verifiers checks the published state. Fraud proofs assume at least one honest and able validator (CRITICAL). **References** - [How is fraud proven - Arbitrum documentation FAQ](https://docs.arbitrum.io/get-started/arbitrum-introduction) ### Challenges A challenge can be started between two siblings, i.e. two different state roots that share the same parent, by calling the `startChallenge` function. Validators cannot be in more than one challenge at the same time, meaning that the protocol operates with [partial concurrency](https://medium.com/l2beat/fraud-proof-wars-b0cb4d0f452a). Since each challenge lasts 6d 8h, this implies that the protocol can be subject to [delay attacks](https://medium.com/offchainlabs/solutions-to-delay-attacks-on-rollups-434f9d05a07a), where a malicious actor can delay withdrawals as long as they are willing to pay the cost of losing their stakes. If the protocol is delayed attacked, the new stake requirement increases exponentially for each challenge period of delay. Challenges are played via a bisection game, where asserter and challenger play together to find the first instruction of disagreement. Such instruction is then executed onchain in the WASM OneStepProver contract to determine the winner, who then gets half of the stake of the loser. As said before, a state root is rejected only when no one left is staked on it. The protocol does not enforces valid bisections, meaning that actors can propose correct initial claim and then provide incorrect midpoints. **References** - [Fraud Proof Wars: Arbitrum Classic](https://medium.com/l2beat/fraud-proof-wars-b0cb4d0f452a) ### Program Hashes #### Celestia Blobstream DA bridge program ZK-friendly implementation of Celestia Blobstream DA bridge that proves that enough Celestia validators have confirmed a given data root. - Hash: `0x00b451fcd696cd0a4025e30bfed96343b1767ac6523a360fee1183f9e2e20745` - Repository: https://github.com/succinctlabs/sp1-blobstream/tree/78a9d3419339a8c60bf51e1e3241f242bc44d434/program - Verification: successful - Used in: [Molten Network](https://ethbeat.org/layer2s/projects/molten) ##### Verification steps Prepare: 1.

CertManager previously validated AWS Nitro cert chains in Solidity - expensive gas cost. - New EspressoNitroTEEVerifier (0xF99De7) delegates attestation verification to a new NitroEnclaveVerifier (0x0d4cD6) that accepts ZK proofs of off-chain attestation validation. Currently EspressoNitroTEEVerifier only works with Succinct SP1 Turbo proofs, however RiscZero and Pico proofs could easily be supported as well. - New NitroEnclaveVerifier (0x0d4cD6) manages zk verifier contracts and allowed program ids, currently only for SP1. - EspressoTEEVerifier (0x7A7E3B, unchanged) now points to the new NitroTEEVerifier. - SafeL2 lost the interact permission on the old verifier (no longer exists). Security implications: same TEE trust model (AWS Nitro), but adds trust in the ZK verifier (RiscZero/Succinct/Pico) and configured program IDs.

For more details please refer to [Arbitrum One](https://ethbeat.org/layer2s/projects/arbitrum) ### 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. **Risks** - MEV can be extracted if the operator exploits their centralized position and frontruns user transactions. **References** - [Sequencer - Arbitrum documentation](https://docs.arbitrum.io/how-arbitrum-works/inside-arbitrum-nitro#the-sequencer) ### 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. After a delay of 1d in which a Sequencer has failed to include a transaction that was directly posted to the smart contract, it can be forcefully included by anyone on the host chain, which finalizes its ordering. **References** - [SequencerInbox.sol - source code, forceInclusion function](https://arbiscan.io/address/0x481863c96f949F5E13932ec2F65470C0CF83808d#code) - [Sequencer Isn't Doing Its Job - Arbitrum documentation](https://docs.arbitrum.io/how-arbitrum-works/sequencer#unhappyuncommon-case-sequencer-isnt-doing-its-job) ## Sequencing ### Espresso TEE sequencer Integration with Espresso sequencing. In addition to providing regular pre-confirmations, the sequencer publishes blocks to the Espresso Network. The integration expects the transaction batch poster to run inside a Trusted Execution Environment (TEE), and it is programmed to verify batch inclusion in a Espresso Network block before publishing it to the host chain. However, the confirmations provided by Espresso Network are additive, and the batch poster can skip Espresso inclusion checks should the Espresso Network be down or unavailable. To ensure the batch poster is running inside a TEE, the SequencerInbox contract on the host chain was updated so that the data posting function also includes a TEE attestation as input (a "quote" / signature) that is verified onchain by the EspressoTEEVerifier for each batch transaction. The verifier checks whether the signature originates from inside the TEE and reverts if unsuccessful. **Risks** - Withdrawals can be delayed if the owner of EspressoTEEVerifier updates the contract verification values (enclave hash, signer) and it is no longer possible to verify the TEE quote. **References** - [Nitro Espresso Integration](https://github.com/EspressoSystems/nitro-espresso-integration/blob/7ddcc6c036fa05cc47560552c85f30b5adedf32c/arbnode/batch_poster.go#L574) - [SGX Quote](https://gramine.readthedocs.io/en/stable/sgx-intro.html#:~:text=The%20SGX%20quote%20is%20a%20signed%20report%20that%20contains%20the%20enclave%20measurement%20and%20the%20signer%20measurement%20of%20the%20enclave%20and%20the%20signer%20of%20the%20signer%20process%20that%20created%20the%20report.) ## Withdrawals The section considers only the L3 properties. For more details please refer to [Arbitrum One](https://ethbeat.org/layer2s/projects/arbitrum) ### 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. The process of block finalization usually takes several days to complete. **References** - [Transaction lifecycle - Arbitrum documentation](https://developer.offchainlabs.com/tx-lifecycle) - [L2 to L1 Messages - Arbitrum documentation](https://docs.arbitrum.io/how-arbitrum-works/deep-dives/l2-to-l1-messaging) - [Mainnet for everyone - Arbitrum Blog](https://offchain.medium.com/mainnet-for-everyone-27ce0f67c85e) ### Autonomous exit Users can (eventually) exit the system by pushing the transaction on L1 and providing the corresponding state root. The only way to prevent such withdrawal is via an upgrade. ## Other considerations ### EVM compatible smart contracts are supported Arbitrum One uses Nitro technology that allows running fraud proofs by executing EVM code on top of WASM. **References** -
