Bitcoin Ordinals aren't "using other chains". Other chains are implementing the Ordinals protocol and it's causing all types of hilarity to ensue.

Ordinals protocol? I thought they were just NFTs on Bitcoin possible due to some esoteric quirk of being able to add extra data

The Ordinals protocol is a way in a UTXO-based model to define and track the smallest unit of account. In Bitcoin's case, it's satoshis. Inscriptions (Bitcoin NFTs) are a way to ascribe data added to the network to an individual satoshi.

This still doesn't explain how inscriptions were happening on Arbitrum when it's not UTXO 🤔
