# **Blobscan: The First Blockchain Explorer for EIP-4844 Blobs**

We’re Blobscan, and we focus on ONE thing: blobs. Blob transactions are a new type of transaction that temporarily stores data on-chain. This temporary data, called a "blob" (short for "binary large object"), plays a crucial role in Ethereum’s scalability by allowing Layer 2 rollups to store large amounts of data off-chain. This reduces the burden on Ethereum’s main chain, enabling more transactions to be processed in parallel, improving efficiency, and lowering costs.

As the first blockchain explorer built specifically for EIP-4844 blobs, Blobscan gives you the power to filter, track, and visualize these transactions in just a few clicks.

## **Our Story**

Born at a hackathon in Devcon Bogotá, Colombia, in 2022, we are well-versed in receiving grant funding and putting it to good use. Thanks to the support we've received, we’ve been able to achieve the following:

## **What we have built so far**

* A frontend that allows navigating the data, having specific pages for blocks, transactions, addresses, and blobs, as well as stats and analytics.  
* An API that allows you to retrieve blocks, transactions, blobs, along with related statistics and time series data.  
* Enables other teams to build on top of blobscan's database.  
* An indexer that communicates with consensus and execution layer clients, fetches blob information, and stores it in different online storage solutions.  
* Easy to deploy using docker images.  
* Support for blob archiving in 2 different storage systems: Google Storage and Ethereum Swarm.  
* Support for 4 networks: Ethereum Mainnet, Sepolia, Holesky, and Gnosis.  
* Support blob decoding for 2 rollups: Starknet and Optimism.  
* Developed [swarm-batch-exporter](https://github.com/Blobscan/swarm-batch-exporter) for monitoring Ethereum Swarm stamps in Prometheus.

## **Ecosystem**

* Collaboration with the Ethereum Foundation DevOps team (EthPandaOps) to deliver a user interface for Ethereum core developers to test blob transactions during the Dencun devnets.  
* Collaboration with Kurtosis (Added support to spin up a local PoS Ethereum testnet with Blobscan).  
* Collaboration with Ethereum Swarm (Sponsoring the archival of blobs in distributed storage).  
* Collaborated with rollups like Starknet to decode their blobs and display the contained information.

## **Milestones**

**Documentation**:

* Created and deployed a documentation site detailing usage, guides, troubleshooting, etc.  
* A guide has been added for deploying Blobscan using **Kurtosis** and **Kubernetes**.

**Web App Upgrades**:

* Enhanced the views for blocks, blob transactions, and blobs by introducing a tabular format to display all elements.  
* Revamped homepage for richer insights.  
* Implemented filtering options for blocks, blob transactions, and blobs using parameters such as block timestamp, rollup, block number range, or slot range.  
* Improved stats view with interactive time series charts and added new metrics: gas expenditure comparison, blob price, blob base and max fee, blob gas usage, etc.  
* Added support for displaying decoded Starknet blobs (all blobs pre-Bolt upgrade). See example [here](https://blobscan.com/blob/0x0145b8901886ffd46a652fed01c5fccde82813c509e4d4f8d044df8fe40be217).  
* Refined responsive design for seamless performance on all screen sizes.  
* Added support for easier navigation across transactions by the same sender.  
* Finalized status and reorg badges are now visible for easier tracking of transactions and blobs.  
* Displayed new parameters on top and bottom bar such as current blob gas price and Swarm blob data expiry date

**Backend Upgrades**:

* Migrated the indexer to Rust to improve performance, robustness, and reliability.  
* Added support for Google Storage and Eth Swarm as blob data storage layers by creating a service with an auto-propagation mechanism.  
* Added support for filter query params to retrieve blocks, blob transactions and blobs by block timestamp, rollup, block number range, or slot range.

**Repository Refinements**:

* Added integration tests and telemetry support for advanced observability.  
* Enhanced CI/CD pipeline.  
* Optimized docker images which are 10x lighter.  
* Deprecation of the [blossomlabs/blobscan](https://hub.docker.com/r/blossomlabs/blobscan) image in favor of separate images: [blossomlabs/blobscan-web](https://hub.docker.com/r/blossomlabs/blobscan-web) and [blossomlabs/blobscan-api](https://hub.docker.com/r/blossomlabs/blobscan-api).
