Cardano’s Hydra Layer-2 Surpasses 1 Million TPS in Gaming Test

Cardano’s (ADA) blockchain network recently showcased its Hydra Head Layer-2 protocol during a Doom multiplayer gaming tournament, which demonstrated the platform’s scalability by recording over 1 million transactions per second (TPS). This performance indicates a promising future for the network, which has long been seen as an underdog in the blockchain space.

The tournament, featuring a $100,000 prize pool, provided a robust testing ground for Hydra’s capabilities. At its peak, the protocol achieved 1.04 million TPS, far surpassing the theoretical and recorded limits of competing blockchain networks. For comparison, Hydra’s isolated test performance outpaced Solana’s theoretical maximum of 65,000 TPS and Internet Computer’s (ICP) 209,708 TPS by significant margins.

Benchmarking Against Competitors

Currently, Solana and ICP average over 1,000 TPS, a figure dwarfed by Hydra’s achievements. Even traditional payment processors like Visa, which claim to handle 1,500 to 2,000 TPS, fall short of this performance. This milestone places Cardano’s Hydra protocol in a competitive position among blockchain networks aiming to deliver high-speed transactions.

Hydra’s earlier demonstration in August 2024 showcased a single-player version of Doom operating smoothly at 35 frames per second on the protocol, further underscoring its efficiency and real-world applicability.

Hydra’s Architecture and Capabilities

Hydra, as a Layer-2 scaling solution, addresses blockchain efficiency by managing transactions off-chain. This design improves the speed and efficiency of both transactions and smart contracts. The protocol’s primary feature, called “Hydra Heads,” functions as state channels resembling on-chain environments, allowing groups of users to transfer assets off-chain for interaction through an unlimited number of transactions.

Each Hydra Head is capable of managing approximately 1,000 TPS. Cardano’s founder, Charles Hoskinson, has emphasized its ability to achieve “fast finality,” where transactions become irreversible almost instantly. Setting up and closing a Hydra Head requires a fee, with results eventually posted on the main blockchain. Importantly, the off-chain transactions within the Hydra Heads incur no transaction costs and are not recorded on the main chain.

In 2023, some developers were cautious about promoting Hydra’s million TPS capabilities, suggesting it was misleading at the time. However, the protocol’s performance in 2024 has shown it to be a groundbreaking innovation capable of handling instantaneous, high-volume transactions, as demonstrated during the Doom tournament.

Paving the Way for Future Applications

The successful implementation of Hydra in the Doom gaming tournament marks a significant step for Cardano. As the event continues, it is possible that Hydra will surpass the 1 million TPS milestone again, solidifying its potential as a transformative technology in blockchain scalability.

This achievement highlights Cardano’s commitment to pushing the boundaries of blockchain performance, positioning Hydra as a solution capable of not only addressing scalability challenges but also enabling innovative applications such as gaming and other high-demand use cases. The test underscores the protocol’s ability to bridge blockchain technology with real-world applications, opening new possibilities for decentralized ecosystems.
