It happened. Bitcoin runs DOOM.

To the delight of crypto Twitter and Reddit circles, someone has uploaded a cloned version of the 30-year-old video game classic DOOM to the Bitcoin blockchain as an inscription on the network’s own NFT protocol, Ordinals. 

Thanks to a happenstance loophole enabled by Bitcoin’s Taproot upgrade pushed in Nov. 2021, a budget (read: free) version of DOOM has been permanently etched on a single satoshi via block 774526, which was added to the blockchain on Wednesday morning.

Being written to Bitcoin means the functional game will forever live on the immutable blockchain. As long as the network is online, folks can play this version of DOOM.

Web browsers are still required to compile the code, but forcing unconventional technologies to run DOOM is a meme in tech culture. Crafty hackers have made DOOM run via pregnancy tests, calculators, ATMs, smart watches, toasters and Pelotons — even “unhackable” crypto wallets, among other zany conduits.

While the clone is fun in its own blocky-and-basic way, an actual copy of the real DOOM looks destined to make it to the Bitcoin blockchain sometime soon (a Reddit thread from Feb. 2018 suggests DOOM was once playable on Ethereum, however the linked YouTube video is now unavailable).

DOOM on Bitcoin via a single satoshi

Meanwhile, Ordinals continues to pepper conversation amongst Bitcoiners as the community parses what bringing NFTs to the oldest blockchain really means for the future of network and the NFT ecosystem writ large.

The protocol notably just enabled the biggest-ever Bitcoin block to be mined. A high-definition “Taproot wizard” was inscribed to a satoshi this week, clocking a 3.96MB transaction — close to Bitcoin’s 4MB block size limit (originally 1MB but stretchable via SegWit).

As for the DOOM Ordinal, it was only 31.2 KB big. 

Remember: It’s not the size that matters. The ability to run DOOM is far more important.

Built on Solana, Loopscale is an orderbook-based lending protocol that pairs the efficiency of direct market matching with the flexibility and UX of modular protocols. We believe Loopscale can help scale NNAs in Solana DeFi and act as their foundational credit layer. Stablecoin deposits and select USD-pegged Loops on Loopscale are offering competitive yields, with an additional upside from farming the protocol and adjacent ecosystem projects (e.g., OnRe, Hylo) for potential future airdrops.
