Cardano’s Leios to CRUSH SUI & Solana’s Speed- Details Inside

• Ouroboros Leios aims for millions of TPS on Cardano.
• Charles Hoskinson claims Leios matches Solana/Sui performance with decentralization.  
• IOG Director says Leios will make Cardano one of the fastest blockchains.

Cardano’s upcoming Ouroboros Leios upgrade is set to target millions of transactions per second (TPS), dramatically scaling the blockchain. By splitting transaction processing and block validation, Leios will enable parallel transaction execution, a key innovation for achieving faster throughput.  This decoupling will be executed while still preserving its core principles of security and decentralization.

Nicolas Biri, IOG Director of Software Architecture, believes that with Leios upgrade, Cardano will achieve the fastest Nakamoto-style consensus and emerge as one of the industry’s most performant blockchains. Armed with enhanced throughput, Cardano developers can unlock new possibilities for decentralized applications.

Cardano founder Charles Hoskinson further underscored Leios’s significance, stating that the upgrade will enable it to match the performance profiles of high-throughput blockchains like Solana and Sui, while maintaining decentralization. He highlighted the six years of research and development invested in Leios, emphasizing that the blockchain will be uniquely positioned to offer both high performance and robust decentralization.  

We built Leios to have the same performance profile of (Solana and Sui) and be decentralized. That took six years of research and development—huge value: we’ll be the only ones to have that performance and be decentralized. We will ship Ouroboros Leios. We will get Midgard and Gummiworm. We will connect to all major cryptocurrencies like #XRP and Bitcoin, be their DeFi layer, and give $XRP and Bitcoin a lot of benefit and value. It’s a trade.

Cardano’s 2025 Roadmap

Further in the roadmap, Hoskinson have announced plans to launch innovations like the Midgard, and Gummiworm,  which he sees as critical to scaling the network’s capabilities. The agenda also includes plans to connect ADA with major cryptocurrencies like XRP and Bitcoin.
