Cardano Enhances Scalability with Leios Code Merge and Dijkstra Testnet Launch

Cryptelio Editorial Published 26 Oct 2026 · 13:45 UTC

Cardano is making significant strides in its scalability efforts as developers have successfully merged the Leios code, which aims to enhance the network's capacity by three to five times its current performance. This development is part of the broader Leios roadmap, which anticipates further scalability improvements pending future votes and evidence from the mainnet.

In addition to the Leios merge, Cardano has launched the Dijkstra public testnet, providing a dedicated environment for developers to prepare for the upcoming Dijkstra upgrade. The testnet became publicly available on October 21 and currently operates on Conway protocol version 11.1.3. However, the transition to the new protocol rules will require additional steps, including a prerelease of node version 11.2 and governance actions for the testnet.

This testnet serves as a crucial staging ground for developers to ensure their applications are compatible with the new environment before the mainnet upgrade. It allows for the identification of potential issues and ensures that all components, such as wallets and exchanges, can handle the changes effectively.

While these advancements do not set a specific date for mainnet activation or guarantee immediate impacts on ADA prices, they represent important milestones in Cardano's ongoing development and infrastructure reliability.

New Insights on Cardano's Hydra Scaling

A recent report from Input Output on October 22 revealed that a replay of Midnight claim transactions achieved approximately 1.9 times the throughput on the latest Hydra version. The throughput increased from 42 to 79 claims per second, while total completion time decreased from 590.4 seconds to 339.1 seconds, marking a 43% reduction.

This benchmark, however, should not be interpreted as a universal transaction-speed figure for all of Cardano, as the Hydra protocol processes transactions among its own participants before settling with Cardano.

The report emphasizes that while the controlled replay provides valuable insights, it does not replicate all production conditions, such as dispersed participants and varying demand. Thus, while the newer implementation shows a significant improvement in the claim pipeline's performance, it does not guarantee the same results for every transaction on Cardano.

New Developments in Cardano's Scalability Efforts

  • Cardano's Leios scaling plan includes a launch sequence that extends beyond the hard fork, with a roadmap detailing a gradual increase in capacity.
  • The Dijkstra testnet is designed to introduce necessary rules for the Leios implementation, requiring stake pools to register additional voting keys.
  • The roadmap targets an initial throughput increase of three to five times the current Praos ceiling, with future goals aiming for a ten to fifteen times increase.
  • Transaction size will play a critical role, as different types of transactions consume varying amounts of space and execution resources.
  • The Leios proposal includes additional blocks and certificates to facilitate more transaction work while maintaining the chain's ordering process.
  • The rollout process allows for pauses at various stages, giving operators time to assess hardware and connection capabilities under increased workloads.
  • Future milestones include approved parameters, compatible software, registered operator keys, and results from demanding tests, all contributing to a controlled expansion of network capacity.
