Blobscan

Blobscan is an Ethereum explorer and data service for searching and inspecting EIP-4844 blobs, their contents, and related transactions and blocks. It also provides specialized blob decoding, persistence across centralized and decentralized storage systems, analytics, and an API for querying blob data.

Practical overview

When it fits

Use Blobscan when an Ethereum investigation centers on EIP-4844 blob data, or when an application needs blob-related records and metrics through its API.

Who it is for

  • Ethereum users tracing blob activity to related transactions and blocks.
  • Researchers reviewing blob contents, formats and network metrics.
  • Developers integrating blob, transaction, block or statistics queries through the API.
  • Teams evaluating an open-source explorer and data service for self-hosting.

Documented uses

  • Find blobs using a versioned hash, KZG commitment, transaction hash, slot or block number.
  • Inspect blob contents and access decoding for supported specialized formats such as rollup blobs or blobscriptions.
  • Review charts and metrics about blobs, blocks and transactions.
  • Query blob-related records and statistics through the API.
  • Retain blob data using multiple centralized or decentralized storage systems, including in response to chain pruning.
Before you choose

Requirements & limits

The project is open source under the AGPL-3.0 license. Its repository lists Docker images for the web and API components and links to separate installation documentation.

  • Search accepts versioned hash, KZG commitment, transaction hash, slot or block number.
  • Specialized decoding is described for rollup blobs and blobscriptions.
  • Blob persistence is designed to use multiple centralized and decentralized storage systems; the project does not specify which configurations a particular deployment uses.
  • The repository identifies separate web and API Docker images, so self-hosting requires consulting the installation documentation.
  • The API covers blobs, associated blocks and transactions, statistics and metrics.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Search and inspect Ethereum blob transactions

Find an EIP-4844 blob and inspect its content and related transaction or block.

Before you start

  • A search value: versioned hash, KZG commitment, transaction hash, slot, or block number.

Steps

  1. Search Blobscan using one of the supported identifiers.

  2. Open the matching blob to examine its content.

  3. Inspect its associated transaction and block.

Expected outcome

The blob, its content, and associated transaction and block can be explored.

Guide limitations

  • The README does not specify exact interface steps or confirm how every blob format is displayed.
  • Specialized-format decoding is described for formats including rollup blobs and blobscriptions.
