About this episode
This episode discusses Cardano's Leios scaling solution and its implications for the blockchain trilemma.
Leios is Cardano's scaling solution for the future. It's basically an upgrade of the layer one to make it faster. What you’ll learn: • Leios is Cardano's scaling solution for the future. • It's basically an upgrade of the layer one to make it faster. • And what it will do, will propel Cardano to be on par with our competitors in terms of throughput and capacity to support more and more app… • I'm pleased to tell you, actually, we're in active development now of Leios. • We're working on the original node, the Haskell node. • I'm happy to tell you that it's coming this year in 2026.
