Signet

Signet is a deliberately minimal Ethereum rollup that removes proving systems and state roots, replacing cross-chain asset movement with market matching rather than proofs: assets are bought and sold across chains instead of being locked and transported, so entry and exit between mainnet and the L2 settle inside the same Ethereum block with no waiting period.

Block production uses round-robin assignment instead of an auction, removing bidding for ordering, and conditional transactions make each cross-chain operation complete or revert as a whole, so market making, liquidations and oracle updates can react to mainnet events in the same block. Execution is fully EVM compatible, standard tooling points at the network directly, and a node runs as a light upgrade of an existing Ethereum node. It is built by the Init4 research collective, with de-complexification itself as the thesis.
