Creating a Purpose-Built Data Indexer

Blockchain datasets offer a wealth of rich, open data, but their rapidly evolving standards and non-regular structures pose unique data challenges. In this talk, I’ll explore the approach we took to make engineering trade-offs at Yakoa when creating the digital asset indexer that powers our services. From outlining the various models for chain-based indexers, to selecting an anchor model in our data schema, to navigating irregular data structures, I'll share hard-won lessons on architecting systems resilient to blockchain's intrinsic complexities. I’ll then reflect on how these technical decisions struck a balance between ideal long-term solutions and messy real-world constraints, and how that foundation influences our client-facing applications.
