What is Astria? Astria has its roots in two projects, the Cevmos project (an early attempt to build EVM-based compilations on Celestia) and Rollkit (fka Rollmint or Optimint). So what is Astria? The project What’s outstanding? Let’s find out with Weakhand.

Overview of Astria
What is Astria?
Astria is a Layer 2 in Celestia’s ecosystem. Astria replaces the centralized sequencers on current Layer 2 platforms such as Arbitrum Optimism, zkSync,… allowing multiple Rollup platforms to share a network of decentralized sequencers in a simple way. Simple and no licensing required to participate. Astria offers instant censorship resistance, fast block confirmations, and cross-chain interoperability.
Astria EVM can overcome the scalability, performance, and decentralization limitations that other EVMs face. Astria EVM helps launch Celestia’s aggregated ecosystem by serving as a cross-chain and liquidity hub, both within Celestia’s existing data cluster and with other ecosystems.
Astria network components
- Astria Sequencer: The block producer node provides block order commitments.
- Data Availability Layer (Celestia): The DA layer provides finality.
- Rollup (Geth): The aggregation node performs state execution and storage.
- Composer: Write pipeline middleware to convert aggregate transactions into sequential transactions.
- Conductors: Path reader middleware helps filter sequencer “meta blocks” for the namespace of an aggregate.
- Relayer: Broadcast blocks from the sequencer to the aggregation nodes and post the blocks to the DA Layer.
Astria’s mechanism of action
Write Path: Send transaction
- Users connect to the Geth pool using a standard Ethereum engine like Metamask or Foundry, and sign and send transactions to the pool’s storage.
- Composer retrieves pending transactions from aggregate memory in the order they were received (i.e., first come, first served), wraps them in an Astria transaction, and sends them to Astria’s CometBFT memory.
- Astria Shared Sequencer Network creates a single “meta block” consisting of transactions sent to its cache by one or more aggregations.
- Blocks sorted from the sequencer will be Relayer retrieves, sends them to both Conductor and the data availability layer, Celestia.
Read Path:
Retrieve and execute block
- Each compilation runs its own instance of Conductor. Conductor receive individual blocks with Astria sequencer soft commits with Astria block time ~1 second and block batches with firm commits from Celestia with Celestia block time ~11 seconds . Conductor filters these blocks or batches of blocks to contain only data for its particular compilation’s namespace. The filtered blocks are passed to the aggregate for execution, resulting in the aggregate state and parent state being updated.
- When Conductor receives a series of blocks from Celestia that it previously saw from Astria, it notifies the synth that the blocks have been completed.
