Facet uses FCT as its native gas token, which is minted through L1 gas consumption rather than being pre-minted. FCT issuance is directly tied to the amount of L1 ETH burned to pay calldata gas in Ethereum transactions.

Each bridge has its own smart contract counterpart on the L2, meaning the same L1 tokens bridged through different bridges will result in different L2 token representations.

Facet does not designate a canonical bridge and allows multiple bridges to be deployed that use the same Rollup state for depositing and withdrawing assets.

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 EOA inbox on the host chain directly.

There is no privileged entity that sequences transactions or produces blocks. This activity is permissionless and open to anyone.

The system uses @SuccinctLabs SP1 zkVM and Prover Network to generate zero-knowledge proofs that verify L2 state transitions. Anyone can submit a validity proof through the proveBlock() function of the Rollup contract to bypass the optimistic flow and settle an anchor block.

Validity proofs bypass the optimistic flow and can invalidate multiple incorrect optimistic proposals simultaneously targeting the same state root. When optimistic proposals are challenged, proposers must defend their claims by providing ZK proofs within the proving window.

The system operates on two parallel tracks: an optimistic track where whitelisted proposers submit state roots with ETH bonds that can be challenged within a time window, and a validity-proof track where anyone can submit direct ZK proofs for immediate resolution.

Facet implements a dual-track proving system that combines optimistic proposals with bonds with ZK validity proofs. The system allows bypassing the 7-day fraud proof window by providing a ZK proof.

Facet blocks preserve the exact order in which Ethereum includes these transactions. Additionally, L1 smart contracts can create Facet transactions by emitting events with the Facet event signature, where the event data payload contains the same RLP-encoded transaction data.

Facet uses a based sequencing model where transaction ordering is determined entirely by Ethereum L1. Users submit transactions to an immutable address on Ethereum with transaction information encoded as RLP calldata.

Another Stage 2 🟢 rollup on L2BEAT! 💗. Introducing @0xFacet - based rollup built on OP-Succinct using based sequencing and multi-bridging. How does it work? 👇

RT @VitalikButerin: Amazing to see so many major L2s now at stage 1. The next goal we should shoot for is, in my view, fast (<1h) withdraw….

RT @l2beatgov: 📢Governance Review #63 is out!. New month, fresh proposals. Activity dipped a bit, but the governance boat’s still afloat.….

RT @hubkotl: Ronin is coming back as an Ethereum L2 – and this is only the start of a massive L1 → L2 migration! 🫨. I’d love to see the fac….

RT @KintoXYZ: Kinto successfully retains Stage 1.

Glad to report that all 6 rollups affected by the recent Stage 1 requirements changes have performed the necessary upgrades and are now fully compliant. That includes:. - @base.- @Optimism.- @unichain.- @Scroll_ZKP.- @inkonchain .- @KintoXYZ. Now onwards to Stage 2! 🫡

RT @poolnoodle93: we did the first ever mainstream deployment of an L2 (@Optimism) with @viamirror. everyone else followed.
