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.

RISE public mainnet launch
2026 May 1st
RISE opens its mainnet (genesis on January 5th 2026) to the public together with the RISEx exchange.
Fraud proofs allow actors watching the chain to prove that the state is incorrect. Single round proofs (1R) only require a single transaction to resolve. ZK proofs are used to prove the correctness of the state transition. The system currently operates with a closed set of 1 whitelisted challenger.
There is no window for users to exit in case of an unwanted upgrade since contracts are instantly upgradable.
Only the whitelisted proposers can publish state roots on L1, so in the event of failure the withdrawals are frozen.
Transactions roots are posted onchain and the full data is posted on EigenDA. The sequencer is publishing data to EigenDA v2. The DACert Verifier is used to verify attestations from the EigenDA operator set that the data is indeed available. If EigenDA becomes unavailable, the sequencer falls back to Ethereum.
Funds can be lost if the sequencer posts an unavailable transaction root (CRITICAL).
Funds can be lost if the data is not available on the external provider (CRITICAL).
State roots are proposed by whitelisted proposers who create dispute games via the DisputeGameFactory by posting a bond of 0.0 ETH. Once created, the game enters a challenge period of 1d during which whitelisted challengers can dispute the proposal by posting a bond of 0.00000025 ETH. If challenged, anyone can submit a ZK proof to prove the correct state within the proving period of 7d. After the challenge period passes without a successful challenge, or after a valid proof is submitted, anyone can resolve the game and finalize the state root.
Funds can be stolen if the validity proof cryptography is broken or implemented incorrectly.
Funds can be stolen if no whitelisted challenger disputes an invalid state root before the challenge window expires (CRITICAL).
Funds can be stolen if the proposer routes proof verification through a malicious or faulty verifier.
Funds can be frozen if the permissioned proposer fails to publish state roots to the L1.

MEV can be extracted if the operator exploits their centralized position and frontruns user transactions.
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 user initiates the withdrawal by submitting a regular transaction on this chain. When a state root containing such transaction is settled, the funds become available for withdrawal on L1 after 3d 12h. Withdrawal inclusion can be proven before state root settlement, but a 7d period has to pass before it becomes actionable. The process of state root settlement takes a challenge period of at least 1d to complete. Finally the user submits an L1 transaction to claim the funds. This transaction requires a merkle proof.
If the user experiences censorship from the operator with regular L2->L1 messaging they can submit their messages directly on L1. The system is then obliged to service this request or halt all messages, including forced withdrawals from L1 and regular messages initiated on L2. Once the force operation is submitted and if the request is serviced, the operation follows the flow of a regular message.
OP stack chains are pursuing the EVM Equivalence model. No changes to smart contracts are required regardless of the language they are written in, i.e. anything deployed on L1 can be deployed on L2.
