This document focuses on functions for each component.
generateAttestation: Generate an attestation proving that the batcher is
running in a TEE that can be trusted.
initializeBatcherState: Initialize the batcher’s state based on finalized data
from Espresso and L1.
submitToEspresso: Submit transactions with the batcher signature to
Espresso for fast confirmation, and handle errors during submission.
computeBlobHashes: Compute the hashes for finalized transaction blobs
within a batch.
signBlobHashes: Sign the computed blob hashes using the batcher’s attested
private key.
submitToL1: Submit finalized and validated batches to L1.
register: verify a TEE attestation on an ephemeral key and add it to the
set of allowed keys
authenticate: verify an ephemeral key signature on a batch commitment
and record the commitment as an acceptable batch to post
isValidBatch: check if a batch is acceptable to post
fallback: accept batches, reverting if they are not authenticated with the
Batch Authentication Contract.
fetchFinalizedBatches: Retrieve finalized batches from Espresso using the
HotShot query service.
validateBatchConsistency: Validate batch consistency using Merkle proofs
and sequence numbers.
reprocessForReorg: Handle L1 reorgs by re-fetching and re-processing
affected transactions.
deriveState: Reconstruct the state according to the processed batches.
