According to BlockBeats, the co-founder of Bitcoin NFT project Blob and the sixth-ranked contributor to the Ordinals protocol, @Elocremarc, has announced the introduction of 'recursive runes'. Following this announcement, the floor price of Blob has risen by 30%, breaking through 0.04 Bitcoin.

The term 'recursive' is understood to refer to 'on-chain pointers' that allow inscriptions to reference data on the Bitcoin chain, including data from other inscriptions. This data can include the latest block height, specified block height, and other inscription data, among other things. These are also known as 'recursive endpoints'.

@Elocremarc's proposal involves adding a 'recursive endpoint', specifically '/r/output'. Once this recursive endpoint is added, developers will be able to determine the quantity of corresponding runes and whether there are other inscriptions from the transaction output. This will allow inscriptions to change based on the quantity of runes.

Based on current understanding, this requires maintaining corresponding inscriptions and runes in a UTXO. If the balance of the runes changes, it will not be possible to determine the change in the balance of the runes from the transaction output, thus causing the inscription image to change accordingly. This suggests that we can look forward to this type of gameplay, such as engraving inscriptions and recording a small image at the same time. Depending on the number of corresponding runes, the resulting small images will be different.

More advanced gameplay, such as a full-chain Bitcoin game mentioned by Pizza Ninjas CEO @TO (for example, one NFT equals one game account, runes are game coins, and the game coin balance can be read directly on the NFT), may require further infrastructure support.

Finally, it should be noted that the addition of the '/r/output' recursive endpoint is a prerequisite for @Elocremarc's plan. Currently, @Elocremarc has submitted a PR on the official Ordinals Github. If it passes smoothly, we will have 'recursive runes' to play with.

In conclusion, 'runes' have been a hot topic in the crypto market over the past week, but despite high attention, they have not shown a good money-making effect. In addition to the 'pre-mining runes' of the project party and the 'fair casting' once played by BRC-20, 'runes' may need more gameplay to stimulate. If 'recursive runes' can be quickly implemented, it will undoubtedly be a strong boost for 'runes'.
