币界网报道：Cardano's ADA token dropped to $0.5818 on Saturday, extending weekly losses despite growing attention on the network's upcoming Leios upgrade. The token fell 3.77% in 24 hours with trading volume spiking 38.39% above the weekly average. Input Output Global (IOG), Cardano's research arm, detailed Leios' design in a recent X thread, explaining it will optimize transaction processing through mechanisms like endorsements while maintaining security. First proposed in 2022 as an Ouroboros variant, Leios addresses scalability limits in existing protocols through architectural changes including faster chain sync and tiered fees. IOG CEO Charles Hoskinson stated the upgrade could launch on mainnet by 2026, two years ahead of initial projections. Meanwhile, ADA's price consolidated between $0.573-$0.588 after volatile trading, with technical indicators suggesting accumulation. Long-term holders continue withdrawing ADA from exchanges, signaling confidence despite recent price declines.
