My dear, in a tweet so tantalizing it could only be described as the social media equivalent of a Noël Coward bon mot, the ever-so-clever Cardano builder, Input Output Group, has announced that the Leios testnet is gracing us with its presence in June. How utterly thrilling! Years of research, hundreds of simulations-one can only imagine the endless cups of tea consumed-and now, darling, we’re finally shifting from theory to delivery. Bravo!
Leios testnet is landing in June.
This work builds on years of research and hundreds of simulations, and marks the shift from theory to delivery.
Leios targets a 10 to 65x increase in throughput and moves Cardano toward 1,000 plus TPS, with mainnet planned by the end of 2026.…

The Leios upgrade, my darlings, promises a 10 to 65x increase in throughput-a feat so audacious it makes one wonder if they’ve been taking lessons from a certain Mr. Bond. Cardano, ever the über-efficient hostess, aims to accommodate 1,000 plus TPS by the end of 2026. How très chic!
‘The O.C.’ Star Lambasts Bitcoin on American TV
Leios, you see, doesn’t replace the darling Ouroboros Praos-heaven forbid! Instead, it introduces Endorser Blocks and committee-based validation, a bit like a well-choreographed cocktail party where everyone knows their role. The result? A 10 to 65x throughput increase, all while keeping decentralization intact and stake pool operations economically viable. How marvelously civilized!
In June 2026, Leios is expected to reach an early public testnet milestone. During this cycle, CIP-164 was merged, and initial throughput was demonstrated on an alpha feature-complete implementation. One can almost hear the champagne corks popping!
The 2026/27 cycle, my dears, is all about maturing Leios from a prototype to mainnet-ready, progressing through software readiness levels 5 to 8. It’s like watching a caterpillar transform into a butterfly, but with far more algorithms and fewer wings.
Cardano launches treasury proposals
This week, Input Output Group announced that the IO 2026 treasury proposals have gone live. Nine initiatives, no less! Each one designed to help Cardano hit its 2030 targets and move toward a more decentralized ecosystem. How utterly ambitious!
Among these, the Developer Experience initiative-a six-month program to streamline Cardano’s developer tooling, documentation, and onboarding-aims for a 30% improvement in developer growth rate. Darling, it’s like giving the developers a personal valet!
The Consensus initiative delivers sustainable throughput capacity at the Consensus layer, including Leios. Cardano Upgrades include account address upgrades, multi-asset treasury, and Babel Fees-because who doesn’t love a good upgrade?
The L2 Scalability initiative promises production-ready L2 infrastructure through Hydra production hardening, Midgard mainnet launch, and shared L2-agnostic primitives. It’s all so terribly technical, but one must applaud the effort!
Cardano High Assurance delivers automated formal verification and a unified developer toolkit for smart contract development. Cardano Maintenance ensures core platform maintenance, support, and operational infrastructure. The Plutus initiative makes Cardano’s smart-contract platform easier to build on, cheaper to run, and more rigorously verified. Blockfrost scales decentralized data infrastructure, and Pogun offers an end-to-end Bitcoin DeFi solution for Cardano. Phew! What a mouthful!
In conclusion, my darlings, Cardano is not just setting the stage-it’s building an entire theater. And we, the audience, are in for a show. Now, if you’ll excuse me, I have a martini to attend to. Cheers!
