Casey Rodarmor is a software developer and a Bitcoin enthusiast who has been contributing to the Bitcoin ecosystem for multiple years. He is best known for developing the Bitcoin Ordinals protocol, which enables the creation of Non-Fungible Tokens (NFTs) on Bitcoin. 
Rodarmor attended a community college where he failed many classes but was able to keep the grades from bringing his GPA down by using “weird administrative tricks” and was able to land a transfer to University of California, Berkeley with a 4.0 GPA. He enrolled at UC Berkeley in August 2006 and graduated with a Bachelor’s degree in Computer Science in December 2009. 
I had been going to community college and I hadn't been the best student but every time that I like dropped out or failed classes I would play these like weird administrative tricks to make sure that those grades never got on my GPA so even after dropping out of Community College like three times I had a 4.0. I kind of fooled them uh and then uh I was able to transfer to UC Berkeley I studied computer science.
Rodarmor started his career in technology in 2010, and worked at Google where he took on the role of a site reliability engineer, working on the traffic team who were responsible for managing data traffic. After working for Google, Rodarmor joined Chaincode Labs to work on Bitcoin Core, the protocol's main code implementation. 
He later became a co-host of SF Bitcoin BitDevs in San Francisco, which is a community that hosts monthly meetups to discuss technical aspects of Bitcoin. Rodarmor has also been contributing to various Bitcoin-related projects, such as Wasabi Wallet and JoinMarket. He has also co-hosted the Hell Money podcast, which explores topics related to money, finance, and Bitcoin. 
In 2022, he started working on Ordinals full-time and developed the protocol that enables the creation of NFTs on Bitcoin. He was inspired by Bitcoin's pseudonymous founder, Satoshi Nakamoto, who included references to something called "atoms" in the original Bitcoin codebase. He also believed that working on the Ethereum network was not ideal due to it's structure, as well as the programming language used for Ethereum's blockchain: Solidity. So he researched more on Bitcoin and discovered Bitcoin's UTXO model, which he found to be a better fit for NFTs, as it allows for natural serial numbering of tokens. 
I started writing I wrote an ERC 721 contract um that was like a NFT contract on Ethereum and as I wrote it it's just like it's just it was very bad um solidity is really bad the programming model of solubility is really bad everything is mutable, everything is super insecure compared to the building blocks of Bitcoin the building blocks of Ethereum are not very good it doesn't have native multisig doesn't have time locks there's all these weird things
Rodarmor's motivation was to make Bitcoin fun again, especially during the bear market, and to create a better version of NFTs. The Ordinal protocol outlines a way in which to sequentially number Satoshis (the smallest unit of bitcoin), and then inscribe data onto those Satoshis to make digital artifacts. 
Rodarmor is now the founder of Ordinal Labs, which was launched on January 21st 2023, and has also been a self-employed software engineer for Agora since April 2021.
