Raph, the new chief maintainer of the Bitcoin protocol Ordinals, recently merged the recursive inscription No. 2167 update proposed by the creator of the Bitcoin protocol Ordinals, Casey Rodarmor, into the Ordinals code on Github.
According to developer Leonidas.og, inscriptions can now use the special /-/content/:inscription_id syntax to request content from other inscriptions. This simple change unlocks many powerful use cases.
For example, instead of inscribing 10,000 JPEG files individually for a PFP collection (which would be very expensive), it would be better to inscribe 200 features from the collection, and then make 10,000 more inscriptions, each using a small amount of code to request the features and render the image programmatically.
Artwork is simply stored on-chain in a more efficient manner, which in the case of Bitcoin Apes saves over $1 million in transaction fees.
In addition, it is possible to completely burn many code packages on the Bitcoin chain, because the code (text form) is called, so the volume is very small, which allows the size of the inscription to break through the 4MB limit of the Bitcoin block size. Complex 3D video games are fully on-chain to Bitcoin.
