TLDR:Cardano Leios is the final requirement in Charles Hoskinson’s personal definition of a complete Cardano network, but the upgrade remains in public testing.Musashi Dojo’s Earth phase peaked at 26.8 TxkB/s, roughly six times the current Praos ceiling, but the metric measures data throughput rather than TPS.Linear Leios is targeted for phase one of the Dijkstra hard fork in late 2026, subject to governance approval, pool readiness, and staged parameters.Hoskinson offered no technical description of the Midnight concept he called his magnum opus, leaving the announcement short of a product confirmation.Cardano Leios has become Charles Hoskinson’s stated finish line for the network he founded. In an October 17 exchange, Hoskinson said Cardano would be complete only after the throughput upgrade reaches mainnet. The comment defines his personal completion standard, not a formal release declaration. Cardano Leios remains on a public testnet, where its first phase peaked at 26.8 TxkB/s. That figure measures transaction data per second, rather than transactions per second. Hoskinson also teased an undeveloped Midnight concept he called his career’s magnum opus. He supplied no technical design, launch date, or product specification for the privacy-focused partner network.Cardano Leios Sets the Final Bar for Network CompletionHoskinson’s reply did not change Cardano’s roadmap or create a new governance action. It instead framed Leios as the last major element in his original design. He cited decentralized consensus, on-chain governance, continuous development, eUTXO, Plutus, scalability, formal methods, and independent node clients.I'm working on a concept that only midnight can bring to the cryptocurrency space that solves most of the problems. Almost have all of it designed conceptually. It's the magnum opus of my career— Charles Hoskinson (@IOHK_Charles) October 17, 2026He also described a network that can improve through its own governance processes. The statement therefore concerns completeness in the founder’s view. It does not confirm that every future feature, application, or engineering task has ended. He noted that millions of people already hold ADA, which makes the final milestone relevant beyond the engineering team.Cardano Leios is an Ouroboros extension designed to expand throughput without replacing the Praos chain. Block producers publish larger endorser blocks beside regular Praos blocks. A stake-weighted committee verifies these blocks and creates a certificate for their contents. The arrangement leaves the underlying proof-of-stake chain in place.Under the design, the committee is weighted by staking share. Certified endorser transactions enter the ledger through the existing Praos sequence. Its objective is to process more transaction data while preserving the consensus system already used on mainnet.Midnight enters the story separately. Hoskinson said he had almost completed a concept that only Midnight could deliver to crypto. He described it as the magnum opus of his career and said it could address many industry problems. The post contained no architecture, feature list, timeline, or governance proposal.That leaves the announcement as a personal preview, rather than a confirmed product release. Neither the Midnight tease nor the Leios milestone establishes an immediate effect on ADA.Cardano Leios Testnet Result Needs Context Before MainnetMusashi Dojo launched on June 23 as the public Cardano Leios testnet. Its Earth phase reached a peak of 26.8 TxkB/s, compared with 4.51 TxkB/s for mainnet using Praos alone. The test result is roughly six times the current mainnet ceiling.TxkB/s measures transaction kilobytes processed each second. It is not a TPS reading, and it cannot be treated as a direct mainnet transaction count. The trial tested the full protocol across real distances and latencies. It was the first public network run rather than a simulation.The initial phase exercised the protocol publicly, including Praos blocks, endorser blocks, stake votes, and certificates. The development report listed more than 127,000 blocks, 30,000 endorser blocks, and nearly 8,000 certificates. Engineers also found five incidents during testing, including forks and synchronization failures.The report said they were implementation bugs rather than design failures. Those results still apply to the testnet environment, not production conditions.Linear Leios is slated for the first phase of the Dijkstra hard fork, targeted for late 2026. The date remains subject to Cardano’s on-chain governance process. DReps, stake pool operators, and the Constitutional Committee must ratify a hard fork action.Stake pools must then register BLS keys for Leios voting. Parameter changes will raise throughput in steps after activation instead of a single network-wide jump.The post Cardano Leios Testnet Logs 26.8 TxkB/s Ahead of Mainnet Push appeared first on Blockonomi.
