Hydra Heads Take on Classic Games

Charles Hoskinson, Cardano's founder, recently discussed Bitcoin and BitcoinOS (BOS), a smart contract operating system designed for Bitcoin to bring

Cardano founder Charles Hoskinson shared that after a team of developers successfully implemented the popular video game “Doom” on Cardano’s Hydra layer two (L2) solution, programmers are now aiming to get a Nintendo emulator working on Hydra.

In an interview with Scott Melker, Hoskinson discussed Bitcoin and BitcoinOS (BOS), a smart contract operating system designed for Bitcoin to bring advanced capabilities and seamless interoperability.

Recently, in a partnership announcement, Cardano joined forces with BOS to integrate the Grail bridge, opening up Cardano's decentralized finance (defi) sector to Bitcoin's $1.3 trillion liquidity.

According to BOS, this collaboration provides Cardano users and developers secure, trustless access to Bitcoin's assets, enhancing cross-chain operability and boosting Cardano's defi potential.

Speaking about BOS and Hydra in a recent interview, Hoskinson explored the possibilities for BOS and Cardano together with Hydra's L2 solution.

Hydra enhances Cardano’s transaction efficiency and reduces delay by handling processes off-chain. It supports parallel transactions through “Hydra Heads” or state channels, enabling faster interactions. During the discussion, Hoskinson mentioned that developers successfully got the classic video game “Doom” running on Hydra. The demonstration showcases “Doom” running on a Hydra head, with smart contracts verifying in-game state changes.

Every action a player takes—whether walking, shooting, or looking around—gets logged as a transaction via a smart contract call on the Hydra L2 chain. Hoskinson then went on to say, “I'm gonna tell you the next thing we're gonna do… gonna break the news right here. The next thing I'm going to do after we do Hydra for the whole deathmatch for Doom, we're going to try to get a Nintendo emulator working on Hydra.”

“So you can play any Nintendo, any Super Nintendo, these types of games on Hydra, how about that?”

The founder of Cardano shared insights into the dynamic world of speed-running, a community of gamers passionately committed to finishing video games at breakneck speeds.

“That's a massive community,” he said. Over the years, this community has flourished, especially with the popularity of video-sharing and streaming sites like Youtube and Twitch. Speedrun.com, the ultimate leaderboard hub for speed-running, now hosts over 2 million recorded runs, spanning more than 20,000 games.

The addition of gaming features and advanced Bitcoin interoperability aims to mark a new chapter for Cardano’s ecosystem—though whether it truly broadens its scope beyond standard blockchain tasks remains to be seen.

Together, Hydra's capabilities and Cardano's collaboration with BitcoinOS (BOS) intend to set the platform on a path to redefining decentralized interactions.

Today, cardano (ADA) ranks as the 11th largest asset by market cap, showing a modest 2.8% gain—yet it's still down 5.8% over the past week. And looking at the 30-day numbers, ADA has slid 16.2% against the U.S. dollar.
