 # Blob Syncer
 
+## Overview
+
+The Blob-Syncer is the service sitting between Greenfield and Ethereum, it constantly fetches blobs from Ethereum, blobs from a range of slots will be assembled into a bundle and
+uploaded to the [Bundle Service](https://docs.bnbchain.org/greenfield-docs/docs/api/bundle-service/), finally persisted into Greenfield for permanent archiving. The blob-syncer service also provides APIs for users to query historical blobs.

 notification and not ready for production use. The code and security audit have not been fully completed and not ready
