Episode notes
Indexer Pivoted From EVM To Bitcoin Overnight
- Errol Binari pivoted his EVM-focused indexer to track Ordinals after seeing early demand within a week of launch.
- He adapted tooling built for faster blockchains to Bitcoin's 10-minute blocks and repurposed it to index inscriptions and BRC20 activity.
Taproot Enabled On Chain NFTs With Ordinals
- Taproot expanded Bitcoin's expressive surface area beyond payments into richer on-chain data capabilities.
- Casey's Ordinals numbered sats and enabled inscriptions, turning individual sats into on-chain NFTs stored directly on L1.
BRC20s Created Token Mania With Simple JSON Inscriptions
- BRC20 turned Ordinals into a fungible-token culture by inscribing JSON ledgers, creating tokens without smart contracts.
- Domo's simple JSON deploy/mint/transfer inscriptions and off-chain indexers drove a 10x spike in transaction volume.
