Leios Testnet dey Move Cardano Scaling From Research go Real World Testing

Carlos Lopez De Lara, product manager for Leios for Input Output, show for the premiere episode of Block//45 to explain Cardano next major scaling track.

The interview focus on how Leios dey add new block structure to Cardano, why dem dey prepare the Musashi Dojo testnet, and wetin SPOs and dApp developers suppose test before any future mainnet decision.

The interview feature Carlos Lopez De Lara, @carloslodelar, and Lily Brodi, @lilybrodi, host am, with Paul from Cardano With Paul, @CardanoWithPaul.

Leios Dey Add Endorser Blocks join Cardano Praos Model

Lopez De Lara describe Leios as Cardano scaling solution wey dey use the time between Ouroboros Praos blocks to create additional block type wey dem dey call endorser block. Praos still be the base protocol and security layer, while Leios dey work as overlay protocol wey dem design to add throughput when network demand need am.

Under the model wey e explain, SPO wey dem elect as slot leader fit announce say e dey create endorser block. The standard Praos block and the endorser block go then move through the network side by side. If dem validate the endorser block, the next Praos block go include certificate wey contain votes from SPOs wey validate am.

The purpose of the endorser block na to carry more transaction data pass regular Praos block. Lopez De Lara talk say Cardano currently dey process about 4.5 transaction kilobytes per second and say Leios fit scale the system reach 200 transaction kilobytes per second. E still talk say the initial configuration no suppose start for the upper limit, because big sharp increase fit create unnecessary costs for SPOs.

Instead, the early target fit start around two to five times the current throughput, while the underlying machinery go dey in place for later scaling. That approach position Leios as staged throughput upgrade, no be immediate jump to maximum capacity.

Lopez De Lara still connect Leios to Cardano long term economic model. E talk say the network 2030 vision, including target of 27 million monthly transactions, no fit reach with the current protocol alone. E still add say as reserves dey decline, transaction fees go dey more important, so higher throughput concern long term SPO profitability and network sustainability.

Musashi Dojo Go Test Leios in Five Phases

The interview still introduce Musashi Dojo, the Leios testnet wey dey come wey dem expect for the end of June. Lopez De Lara describe am as intermediate milestone between the original IO Research work, the Cardano Improvement Proposal process, the formal specification and future mainnet implementation.

E talk say the Leios work don move from the original research paper enter optimized protocol proposal, then enter formal specification and now enter prototype implementation. Musashi Dojo dey designed to move that prototype from lab environment go real world conditions, using distributed infrastructure wey SPOs go operate across different regions, hardware setups and network environments.

The testnet name come from Miyamoto Musashi, the Japanese samurai wey dem dey associate with two sword strategy. Lopez De Lara use that comparison explain the Leios design. Praos still be the smaller block and the network heartbeat, while the Leios endorser block act as the larger block wey dem use for different throughput conditions.

The Musashi Dojo structure follow the five chapters of The Book of Five Rings. The Earth phase focus on basic protocol design validation. The Water phase explore protocol parameters and how the system dey behave under different settings. The Fire phase introduce real world infrastructure conditions, including different operating systems, software versions, architectures, hardware and physical network limits.

The Wind phase dem plan am for adversarial testing. Lopez De Lara talk say dem go put Leios under harsh conditions to test how the protocol dey behave when e face difficult or hostile scenarios. The final phase, Void, dey designed for final validation before mainnet preparation, including tagging the node, preparing the release and beginning the hard fork initiation process if the evidence support that path.

SPOs and dApp Developers Dem Dey Ask Make Dem Train Before Mainnet

Lopez De Lara describe Musashi Dojo as training camp where the prototype implementation fit produce failures, feedback and improvements before dem go consider production grade code. E talk say community participation go influence the quality of the testnet results and the level of confidence wey go dey before any future mainnet step.

For SPOs, e talk say the operational setup suppose remain close to the current Cardano node model. The main extra requirement na new set of BLS keys wey dem go use for validating and voting on endorser blocks. E compare their use and registration process to the existing VRF key model.

The Leios website go serve as main entry point for participants. Lopez De Lara talk say e go provide information for running the Leios node, with tutorials, faucet for test ada and faucet for test delegation. For experienced SPOs, the testnet dey presented as familiar Cardano testing environment with one new protocol function join the operational flow.

E still direct message to dApp developers. According to Lopez De Lara, application teams no suppose wait for mainnet before dem test how their protocols dey behave under Leios. Developers fit deploy on Musashi Dojo, test user experience under different throughput conditions and adapt their applications before future mainnet upgrade.

The interview still cover the high confidence track wey dey run side by side with the release candidate work. Lopez De Lara talk say the software implementation na one track, while the second track focus on evidence wey dem need for mainnet decision. That one include protocol design testing, parameter testing, adversarial scenarios and threat model validation.

Dem go use those results by SPOs, DReps and Constitutional Committee members when dem dey review any future hard fork vote. Lopez De Lara talk say the team dey work toward production readiness by the end of 2026, with November mentioned as possible readiness point and December as possible hard fork window if development, testing and community participation continue for the required pace. Musashi Dojo now dey give Cardano operators and application teams defined environment to test Leios before dem put the protocol in front of governance participants for any mainnet decision.
