Astria

Astria is the Shared Sequencer Network. Replace centralized sequencers and maintain sovereignty. Astria lets rollups share a single decentralized network of sequencers that's simple and permissionless to join. Rollups powered by the Shared Sequencer Network get fast block confirmations and the censorship resistance guarantees that can only be provided by a decentralized network. Astria enables atomic transaction inclusion across rollups via its native transaction bundles. By giving users the power of conditional transaction inclusion, Astria unlocks exciting possibilities like atomic cross-rollup arbitrage. Astria can be used without fear of being locked in. All transaction data is stored on the base layer, and Rollups own their execution and state. Swapping out the sequencing layer is as simple as updating your Rollup software.
