币界网报道：Cardano has unveiled plans for its 2026 Leios upgrade, promising to significantly enhance network performance with a 50% throughput increase. The upgrade focuses on improving block propagation efficiency through a novel approach called "lazy propagation," which reduces redundant data transmission between nodes. Input Endorsers, another key feature, will allow transactions to be pre-confirmed before inclusion in blocks, potentially lowering latency. Charles Hoskinson, Cardano's founder, emphasized that these changes maintain the network's security while addressing scalability. The Leios development follows Cardano's recent Node 9.0 release and comes as the blockchain prepares for its Chang hard fork, part of the Voltaire era focusing on governance. The upgrade timeline positions Cardano to compete with other Layer 1 networks that have recently implemented performance improvements.
