🔍 Blobscan Explorer

Open-source explorer and analytics dashboard for Ethereum’s blob data enabling access, decoding, and archiving.

🧩 About

Blobscan is an explorer and API for shard blob transactions. It solves the challenge of accessing, analyzing, and preserving blob data by indexing and storing it permanently across centralized and decentralized storages. It allows to query, visualize, and decode blobs across multiple chains, while accessing an analytics dashboard with blob-related metrics and time series insights.

⚙️ Technical Architecture

• Blockchain(s): Ethereum mainnet & testnets (Holesky, Sepolia, Hoodi) and Gnosis mainnet.
• Backend**:** TypeScript + Node.js + Bullmq + Prisma + PostgreSQL for data indexing.
• Frontend**:** Typescript + Next.js + React + TailwindCSS.
• Indexer: Rust.
• Storage providers: storage agnostic, allows saving blobs to multiple storage providers such as S3, GCS (centralized) or Ethereum Swarm (decentralized).
• APIs**:** REST API (tRPC OpenAPI + Prisma) for blocks and transaction including blobs and blob details.
• Other integrations: Kurtosis, Load Network (prev. WeaveVM).
• Infra/Tools:
  • blobscan-infra - Infrastructure as a Code
  • blobscan-helm-charts - Kubernetes helm charts
  • swarm-batch-exporter - prometheus exporter to monitor status of Swarm batches

💼 Business Model

Who are your users and how do you sustain the project? Possible

• Target users: Rollup developers, Ethereum researchers and data analysts. New rollups with an architecture that relies on blob data, like the escape hatch of Lighter.xyz.
• Go-to-market or adoption plan: Integration with developer tooling; visibility through Ethereum community channels.
