Cardano founder Charles Hoskinson used his live broadcast of his 1st May 2025 to introduce the first quantitative performance indicators for Ouroboros Leios, to update the protocol, which-if it works in production, like a prototype already in a simulation-promotional.
Ouroboros Leos: Cardano's most bolder version update yet
Speaking to Colorado, Hoskinson described Leos as the most ambitious iteration on the Ouroboros research line: telescopic design, which “expands Prows”, can “collapse back to the current protocol” if there is an unforeseen failure. Unlike a separate Byzantine -rich (BFT) engines, Leios is designed to be designed by Cardano's existing evidence of evidence, without abandoning the original 50% Byzantine resistance or 24/7 elastic warranty on the network.
Hoskinson shared a slide of the prototype team, which attracted the attention of the community. The focus metric was the speed of the input block (IB), a new adjustable parameter that multiplies the capacity, inserting many input blocks before selecting each superior block.
“For this one input block, you can see that the maximum is about 6 TPS,” he said, pointing to the graphics. “You have a minimum of five input blocks, 10 input blocks, 20, 30-11,000 TPS [250 Bytes]a maximum of 180 [TPS] 16,000 kg transactions that are huge. ”
As the Count of IB is a parameter, the network guides can raise or lower it in any “tick” period, then devote it to the subsequent “Tock” period to software and network optimizations before re-rotating the clock. In Hoskinson's words: “Cardano, of course, goes faster and does not need a brand new design or protocol for it.”
Leos is the most invasive exchange of the Haskelli knot after the change of 2020 from Ouroboros-BFT to Shelley consensus. The innovation concerns virtually every sub -system: the logic of the ledger, the structure of the blocks, the stack of the network, the rules of consensus and the cryptography. Despite the higher costs and the fatigue of the developer, the “survived” development schedule-multiple teams are introduced, which outlines the code in time zones, despite the higher cost and the fatigue of the developer.
When will Leos edit?
Hoskinson warned that rewriting is non -trivial: “It usually takes about nine months to twelve months to implement this protocol.” The official specification, simulation and Cardano Improvement Proposal (SIP) are expected to be completed in the second half of this year. If these artifacts are available, Global (IOG) input output will provide external companies to propose that the code Haskelli is redundant and potentially rusty, and go when alternative customers ripen on time.
Leos arrives in a separate action plan for layer-2 technologies, Mithriil, medium optimistic roller and recursive pike initiative-it is designed for throughput without damaging decentralization. Hoskinson emphasized that the UTXO model makes Cardano unique the evidence of zero-knowledge: “Every output can be proof, not a transaction.”
The purpose of the strategy is to allow LeOS to equip the base layer, while the layer-2 adds special scale roads, positioning the network to swallow “the huge transaction volume that Bitcoin Defi, XRP Defi and our AVS system could get.”
Hoskinson graduated, repeating Cardano's research -based etho: “No one in the cryptocurrency industry writes sip, has no tight simulations and prototyping, and official specifications as RFP definition. Nobody does.” According to him, Leos is a “chronic achievement of ten -year care, research and engineers … the cornerstone of the Ouroboros Action Plan”.
If the delivery schedule is valid, Cardano stakeholders could vote over the Leios SIP in early 2026, bringing in at least 11,000 transactions per second before the end of next year – without giving up the platform signature.
