As the Ordinals protocol on the Bitcoin chain continues to heat up, innovations based on the Ordinals protocol have begun to emerge one after another, and more and more R&D teams and developers have invested in this innovation revolution."Recently, Bitcoin Inscription has a new story. Raph, the new lead developer of the Bitcoin protocol Ordinals, recently uploaded the "recursive inscription number 2167" proposed by the creator of the Bitcoin protocol Ordinals, Casey Rodarmor, on Github.

The update was merged into the Ordinals protocol, and finally recursion was officially launched in version 0.6.2. Then the concept of recursive inscription was born. This is a new way of inscribing inscriptions with a self-referential feature, i.e. recursive inscriptions allow special syntax to request the content of other inscriptions. In the previous inscription method, each inscription is independent, and there is no connection between the inscriptions. This will expand the possibilities of inscriptions and greatly reduce the transaction costs.

From "static inscriptions" to "recursion" to "real-time interactive" feedback, the narrative of Bitcoin ecology is becoming more dynamic and imaginative. "Recursive inscriptions" may be becoming a new ecological outlet, and "interactive" will give inscription NFT more new ways to play.

What is a "recursive inscription"?

According to the interpretation of the well-known KOL Leonidas of Ordinals, "Recursive inscriptions" refers to a new way of inscription on the blockchain, which can realize mutual reference and calling between inscriptions and inscriptions. Each inscription is an embarrassing situation that is independent and unrelated. Through the combinable feature, the possibility of free combination is opened. Simply put, a recursive inscription is an inscription that requests the content of other inscriptions.

Using the "recursive inscription" inscription method, the inscription uses the special "/-/content/:inscription_id" syntax to request the content of other inscriptions, and the user can use a smaller amount of code to reduce the capacity of the inscription, that is, lower Costs create inscriptions on the Bitcoin chain and enable more complex functions.

In this regard, Leonidas explained that instead of individually inscribing 10,000 JPEG files for the PFP collection (which would be very expensive), it would be better to extract and inscribe 200 features from the collection, and then request these 200 features through the new inscription syntax, and combine the production 10k inscriptions, each using only a small amount of code to request features and combine to render images.

Specifically, in the past, if you want to create 10,000 inscriptions of the PFP collection, you need to upload 10,000 different pictures, and the inscription space will be different due to the different resolutions of the pictures. The fees and costs of engraving pictures are higher. Today's recursive inscriptions only need to upload the key elements required by the PFP collection, such as patterns, characters, accessories, etc., and the special id syntax used can call these elements, and the existing corresponding elements can be recombined and spliced ​​to display As an image, there is no need to upload the entire image.

The first interactive recursive inscription Recursive Playground

"Recursive Playground" is the first interactive recursive inscription NFT project, as its beta version shows, users can change the state of the screen by simply dragging the mouse. Let the inscription NFT change from static and eye-catching to dynamic and real-time interactive, so that collectors can also become co-creators, and they can create their own works based on this.

From the perspective of "Recursive Playground", interactive art is the unique artwork created in real time by personal inspiration and computer interaction in some way.

At present, the "Recursive Playground" project party is still relatively mysterious, and has not disclosed the launch time, price and total amount of its related NFT products. The project party only announced an interactive NFT trial version and some photos.

Just imagine, if we try to change the reaction logic behind the "Recursive Playground" and extend the click interaction limited to the mouse to the gravity system, fluid mechanics, and even time logic, etc., will the "interactive recursive inscription" NFT have it? More playability? NFT will no longer be limited to conveying visual effects through the display screen. Users can feel its existence more through the interaction of the mouse. The user only needs to move their fingers lightly, and the NFT can react to the starting point of the pressure. Ripples.

What kind of possibilities will "interactive recursive inscriptions" bring to the Bitcoin ecological Metaverse?

Let's go back to the "recursive inscription" reading again, as Leonidas said, due to the properties of the recursive inscription, "there will now be a huge package repository for developers to build on", which will unlock under 4 MB forever A powerful use case that can't be done. Just like code compiled together to make complex software, a package repository built through recursive inscriptions could put complex 3D video games entirely on the Bitcoin chain. Bitcoin will essentially become an intranet, with every file requesting data from every other file on Bitcoin, and perhaps happily surfing the Internet via Bitcoin in the not-too-distant future.

Assuming that NFT is used as an electronic pet or a game prop, then through the inscription of recursive inscriptions, NFT can select the elements it needs in the inscription element library to upgrade. Just like the current online games, the characters will have the attributes of growth and upgrading. Similarly, this attribute is also applicable to the Metaverse and the game field. In addition, coupled with the infinite recursive property of recursive inscriptions, theoretically the element library can be compatible with any game or NFT in the Bitcoin ecosystem, so full-chain games are also possible. When your NFT or equipment freely shuttles in the Bitcoin In any game of Bitcoin Ecology, the real Bitcoin Ecological Metaverse will be presented in front of your eyes.

The project provides the basic attribute characteristics of the NFT series, and players can make NFT by DIY and then engrave it. According to the official introduction of the project, Doodinals is the first recursive art collection completely created by the community. Community players can do DIY graffiti on io. All element features support position, zoom and rotation functions, and the SVG files generated by DIY will be burned in On Ordinals, every player's doodle will have the opportunity to be included in the collection series. According to official data, more than 128 avg files have been burned on Ordinals.

Summarize

As Recursive Playground explained that "Bitcoin is art, a canvas, or a computer", the generation of interactive recursive inscriptions breaks the limitations of capacity and plane for the creators of the Bitcoin ecosystem, and makes the Bitcoin network completely become A creative paradise for users, where they can create unique svgs, websites and artworks with just a touch of the mouse.

Users have changed from simple collectors to creators, and the real metaverse also requires the construction and creation of every metaverse user. Interactive may provide another possibility for the realization of metaverse in the future.
