Cardano Enhances Scalability with Leios Code Merge and Dijkstra Testnet Launch

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.
