Astralscan

Overview

Astralscan is a block explorer built for the Astral Protocol, a spatial extension of the decentralized web. It allows users to explore, verify, and interact with location-based attestations recorded onchain. The goal is to make the where of web3 as verifiable and accessible as the what and when.

This project was born from a serendipitous collaboration during my time at Kernel, a community of web3 builders. There I met John from the Astral team, became fascinated with their vision, and volunteered to help bring spatial attestations to life through a better user experience.

Problem

Astral had already developed a prototype called Logbook, which allowed users to create spatial attestations directly on the app. However, it lacked the ability to:

• Visualize attestations across time, space, or chain
• Filter or browse attestations in a meaningful way

There was a clear need for a new interface designed to both visualize and organize spatial attestations and support future development through a unified component system.

Goals

• Design a map-based and list-based explorer for attestations across different chains
• Build a reusable and scalable component library
• Enable users to explore, add, and verify entries with location, media, and metadata
• Improve visual hierarchy and usability
• Lay the groundwork for features like filters, tags, and sharing

Solution

The new app, Astralscan, will allow people to:

• View all attestations on a global map
• Browse entries in a sortable and filterable list view
• Click on entries to see details, including:
  • Location, date/time
  • Media (e.g. image proofs)
  • Description or memo
  • Chain metadata
• Create new attestations with a smoother, more guided UX

Current Status & Next Steps

This is an ongoing project. I’m currently:

• Expanding the entry detail view to show additional metadata
• Improving loading/empty states
• Finalizing and documenting the component library
