Blobscan is the first open-source blockchain explorer designed to navigate and visualize shard blob transactions introduced in EIP-4844. It provides essential public infrastructure to help scale Ethereum, featuring:

• 🔍 Advanced blob search and filtering.
• 🧠 Rich blob decoding (including Starknet and Optimism support).
• 🗃 Multiple persistent blob storage integrations.
• 📊 A detailed analytics dashboard
• 🔌 An API for querying blobs and metrics.
• 🐳 Docker and Kubernetes-ready deployment options.

We see Blobscan as a vital public good for Ethereum’s future and are committed to delivering the tools the ecosystem needs to thrive.

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.

We’re a passionate team of developers who enjoy building open-source tools and working with data. Blobscan is our way of supporting Ethereum’s rollup-centric roadmap. As blobs become a foundational component of scalable rollups, we see a clear need for a tool that helps developers and researchers explore and use this new data layer effectively.

With the introduction of EIP-4844 shard blob transactions in the Dencun Fork, the Ethereum ecosystem faced several challenges:

• Lack of tooling for blob-related data: There was no dedicated tool to easily query, visualize, or monitor blob data across networks.
• Blob data interaction: Developers and users lacked an open, reliable, and user-friendly way to access and interact with blob data.
• Blob data persistence: Once blobs are pruned from the chain, there is no guarantee of their continued availability, threatening data accessibility and long-term integrity.
• Missing blob analytics: There was no easy way to access meaningful metrics or insights into blob data usage or network trends.
• Opaque Blob Data: Blobs are currently accessible only in their raw, encoded form, offering little to no meaningful insight without additional decoding tools or context.

Blobscan addresses these issues by:

• Providing open access to blob data: Supporting Ethereum mainnet, testnets, and chains like Gnosis, Blobscan enables easy querying and visualization through both a web interface and a developer-friendly API for different networks.
• Ensuring blob data persistence: Storing blobs in both centralized and decentralized storage solutions to guarantee their availability and redundancy even after pruning.
• Offering easy-to-deploy Docker images: Delivering easy-to-deploy Docker images that can be seamlessly integrated into existing tech stacks, enabling developers, researchers, node operators, and others in the Ethereum community to work with blob data efficiently and effectively.
• Offering blob analytics dashboard: Providing rollup-grouped blob stats and metrics that offer deeper insights into this new data layer, helping researchers and developers better understand blob activity over time.
• Decoded Blob Delivery: Blobscan decodes blob data and serves it via both API and web interface, presenting the data in a clear, and user-friendly way.
