Bitcoin Ordinals Sync API

Real-time blockchain sync API for a Bitcoin Ordinals marketplace — indexing inscriptions, ownership transfers, and listing events at chain speed.

  • Node.js
  • Bitcoin
  • Real-time Sync
  • REST API

The Problem

Ordinals marketplaces need continuous indexing of inscriptions and transfers; standard EVM-style indexers do not apply.

Stale ownership data breaks trust in listings and trades.

Tech Stack & Architecture

Node.js REST API focused on Bitcoin-native sync of inscriptions, ownership transfers, and listing events.

Ingestion is checkpointed so reorgs and restarts do not silently corrupt marketplace state.

Key Results / Business Outcome

Delivered a real-time Ordinals sync API used to keep marketplace listings and ownership accurate at chain speed.

The marketplace UI can rely on a single ownership source instead of ad-hoc explorer scraping.
