Eigen Zeth

A “Type 0” zkEVM.

Eigen Zeth Architecture

As illustrated in the figure above, Eigen Zeth include these components:

Watcher: Monitors and synchronizes blocks confirmed by the Layer 2 sequencer.
Proposer: Packages a specified number of blocks into a batch in sequential order.
Settlement: Generates a proof for the batched blocks and calls the settlement layer’s verify function for final settlement.
Custom Eigen Reth Node: A custom Layer 2 node based on Reth, designed to receive transactions, determine their order on Layer 2, and generate and confirm Layer 2 blocks.

The transaction life cycle in the Eigen Network contains the following three phases:

Pending: The user submits a transaction to the L2 sequencer. The transaction enters the transaction pool and becomes Pending, waiting to be included in a block by the sequencer.
Sequenced: The sequencer packages the transaction into a block. At this stage, the transaction is confirmed on Layer 2, and the transactions in this block become Committed.
Batching: A certain number of Layer 2 blocks are packaged sequentially into a batch. The transactions in the batch enter the Batching state.
Submitted: Once the batch is complete, it is sent to the DA layer. The transactions in this batch are now Submitted.
Finalized: The Settlement component generates a proof for the batch and calls the Layer 1 Verify contract for final settlement. After verification and inclusion in Layer 1, these transactions become Finalized.
