Ordinals are inscriptions created with the protocol described at: https://docs.ordinals.com/inscriptions.html The protocol was designed by developer Casey Rodarmor, and shares a few similarities with the <AtomSea & EMBII> protocol.

The protocol also includes a way to have ownership over inscriptions, effectively creating an <NFT> system on top of the bitcoin blockchain. <AtomSea & EMBII> also already had such a system however. In either case, <Ciro Santilli> couldn't give less of a fuck about who owns some random publicly viewable digital asset.

For whatever reason, orinals became extremelly popular compared to the <AtomSea & EMBII> format, leading to millions os inscriptions, and 10k+ images as of block 830k. They also started to take up a substatial portion of the available block space.

This in turn led to a lot of <child porn> rediscussion, and people linking back to this page to view earlier inscriptions: <incoming links>.

Unfortunately, unlike <AtomSea & EMBII> and even <cryptograffiti.info> uploads, most ordinals are designed to be just <Ordinal ruleset inscription collection>[souless bulk collectibles], as with as much artistic merit as any random collectible card set or postage stamps you may find at a newpaper stall. To make things worse many of them are likely algorithmically generated. <Eternal September> had truly arrived to the <Bitcoin blockchain>. As a result, <machine learning> would be almost essential in order to find interesting uploads amidst such bulk.

{description=This is the first <ordinal ruleset inscription>: https://ordinals.com/inscription/6fb976ab49dcec017f1e201e84395983204ae1a7c2abf7ced0a85d692e442799i0[]. It was made on block 767430 (https://www.blockchain.com/explorer/blocks/btc/767430[2022-12-14]).}

The `i0` at the end of the URL above means "inscription 0". This is because a single transaction can have multiple inscriptions.

Some of them have sold for high prices. <Magic Eden> is a popular interface for trading them:

The ordinals also started taking up large portions of the Bitcoin blockchain:
