A Brief Introduction to Ordinals
As mentioned in our previous post Bitcoin v Ethereum, developers have recently enabled the Bitcoin blockchain to host a type of NFTs, something that had previously been restricted to younger blockchains such as Ethereum. This new technology is known as Ordinals Protocol, and in this article we will give more detail on this exciting development and Trevor’s adoption of it.

The smallest unit of Bitcoin is known as a satoshi (equal to 0.00000001 bitcoin). Ordinals Protocol allows an individual identifier to be assigned to each satoshi as it is created, thus making each unique. Data (such as artwork) can then be recorded onto a satoshi in a process known as ‘inscribing’, turning the satoshi into a non-fungible token called an ‘ordinal’. Just as with other NFTs, the ordinal can be exchanged between collectors, with transactions recorded on the blockchain.
An advantage that ordinals have over other types of NFTs is that its inscribed artwork is stored entirely on the Bitcoin blockchain. Many other types of NFT store their artwork apart from their host blockchain via a link to an externally-stored image file. This difference guarantees the greater security of ordinals, ensuring that they cannot be altered or disappear due to the external host becoming inactive.

Of course, Trevor has embraced this new development, and ordinals will take centre stage in his upcoming project ‘CryptoAngels’. If you would like to know more, all the details – including a technical help guide for those new to purchasing ordinals – are on our dedicated CryptoAngels site.
A reminder of some of the terms used in this article:
