Cardano Launches Leios Musashi Dojo Testnet, With ADA at 5-Year Lows
Cardano (ADA) launched the public testnet for its Leios scaling protocol today, June 23. It is the most significant technical milestone the network has hit in years, and it arrives with ADA sitting at a five-year price low.
The testnet carries the name Musashi Dojo, after 16th-century samurai Miyamoto Musashi. Its five phases map to the chapters of Musashi’s Book of Five Rings: Earth, Water, Fire, Wind, and Void, progressing from basic design validation through adversarial testing and into mainnet readiness.
The Price Problem
The launch lands in difficult conditions. ADA hit its lowest level in five years this month, down roughly 35% over the past 30 days. Meanwhile, its all-time high of $3.09 came on September 2, 2021, today’s price of $0.16 sits 95% below that peak.

The backdrop is bleak. At first, the analytics platform TapTools shut down earlier this year while Cardano cancelled its 2026 Singapore Summit. Hoskinson warned of a “wave of failures” among Cardano DeFi projects in the same period.
Cardano has lived through an unusual contradiction. The network kept shipping and moving toward its roadmap, but the price went nowhere. Leios removes the most persistent technical criticism of the chain: that the base layer cannot scale.
Whether the market reprices over the next five months of testing, or waits for mainnet, remains the question that defines Cardano’s second half of 2026.
How Leios Works
Leios runs as an overlay on Cardano’s existing Ouroboros Praos mechanism. When demand rises, an elected slot leader produces an additional “endorser block” that travels in parallel with the standard Praos block.
The upgrade targets scaling Cardano from its current throughput of 4.5 KB/s to 200 KB/s. The official roadmap puts that at 30 to 65 times current Praos levels.
Input Output product manager Carlos Lopez de Lara confirmed the initial rollout starts at two to five times current throughput, with the full ceiling available as demand grows.
The Leios governance proposal passed with over 84% support from Cardano’s delegated representatives, and Lopez de Lara is targeting a November 2026 hard fork.
The Cardano 2030 Vision requires scaling from today’s roughly 800,000 monthly transactions to over 27 million; the current base layer cannot get there alone.
