Cardano is entering a transition phase as its development arm, Input Output Global (IOG), reshapes its roadmap. The network is moving away from multiple parallel initiatives and concentrating efforts on fewer, more advanced frameworks.
IOG confirmed that the Acropolis project will be discontinued in April 2026. The initiative was built as a Rust-based node intended to improve infrastructure diversity and had delivered upgrades such as faster blockchain synchronization. Despite these gains, IOG said Acropolis no longer fits the network’s changing direction.
“We’re changing course to prioritize Cardano’s growth. We are ceasing development on Acropolis to focus on chain abstraction and cancelling Tiered Pricing to align with the Leios roadmap. This decision returns ₳4.1M to the Treasury. We’re putting resources where they deliver the most value for the community.” Said IOG.
Alongside Acropolis, IOG also scrapped the Tiered Pricing model. The decision follows research tied to Ouroboros Leios, which suggests upcoming changes in transaction processing could make the pricing system outdated before it is fully implemented.
With these initiatives removed, development is now centered on chain abstraction and Leios-related upgrades. IOG said the changes are expected to simplify how developers and users interact with the network while improving throughput.
Charles Hoskinson suggested that Leios could launch within the year, potentially introducing a more efficient model for scaling without compromising decentralization.
As part of the restructuring, around 4.1 million ADA is being returned to the treasury for community governance. The move has prompted questions from observers.
One X user highlighted a perceived gap between earlier treasury allocations and the returned amount. Based on earlier figures, the user said roughly 2.66 million ADA remains unaccounted for and questioned whether it is tied to existing Acropolis code. The user also flagged issues with the project’s GitHub link, adding to the uncertainty.

Premium gym chains are entering a “golden era” that is ending or already in decline, as rising operating costs collide with shifting consumer preferences toward more flexible, community-based ways to exercise. Long-term memberships are shrinking, margins are pressured by higher rents and facility expenses, and competition from smaller, more personalized…
