Ordinals developers introduced a method called recursive inscriptions to overcome Bitcoin’s 4 MB per block size limit, which limits the size of NFTs. Previously, inscriptions representing tokens and NFTs on Bitcoin were independent of each other and had no knowledge of other inscriptions. The new feature allows inscriptions to reference the contents of other inscriptions using a special syntax. This feature was introduced to the Ordinals system on June 10. Recursive inscriptions can improve efficiency and reduce costs.
