Leios Mainnet Development and Budget Cuts: What Key Signals Does the Cardano 2026 Roadmap Reveal?

On April 22, 2026, the core development company of Cardano, Input Output Global (hereinafter referred to as the core development team), officially submitted nine development proposals for 2026 to the community treasury, totaling $46.8 million, a significant reduction of about 52% compared to $97.5 million in 2025. The voting window has opened, with approximately 1,000 decentralized representatives set to cast their votes, deadline May 24.

The nine proposals do not aim for broad coverage but are highly focused on two main themes: one is network scaling centered on the Leios consensus upgrade, and the other is Bitcoin DeFi access solutions represented by Pogun. Meanwhile, the core development team has officially canceled the Acropolis project and layered pricing scheme, and refunded 4.1 million ADA to the treasury for community redistribution. This series of actions sends a clear signal: Cardano’s 2026 theme is “Narrowing the Fronts, Focusing Delivery.”

As of April 24, 2026, ADA is quoted at $0.2487 on the Gate platform, with a 24-hour trading volume of about $8.8 million, a circulating market cap of approximately $9.15 billion, and a slight 0.53% increase in price over 24 hours.

Key Milestones Review: From Community Rejection to Leios Launch Schedule

The Cardano ecosystem has long faced a core contradiction: deep academic research accumulation, but the network’s throughput limit has long constrained the scale of DeFi and institutional applications. Currently, Cardano’s monthly transaction volume is about 800k transactions, and the core development team’s vision for 2030, as stated in consensus proposals, is to increase this number to over 27 million—meaning a more than 30-fold leap in monthly transaction scale.

The path to achieving this goal has undergone multiple adjustments over the past few years. Since 2025, Cardano has completed several key governance upgrades, with the decentralization representative system maturing, and the community beginning to show stronger accountability in treasury fund allocation. In early April 2026, a $3.5 million meeting sponsorship proposal jointly initiated by EMURGO and the Cardano Foundation was rejected by the community with a high vote against rate of 93%. This event was seen as a significant signal of the community’s sharply reduced tolerance for “non-core expenditures.”

Subsequently, on April 8, the core development team announced the cancellation of the Acropolis project and the refund of related treasury funds, explicitly focusing R&D resources on more prioritized technical frameworks like Leios. On April 22, nine proposals were officially submitted, marking the final stage of community review and voting for Cardano’s 2026 roadmap.

Four-Dimensional Data Perspective: Strategic Choices Behind $46.8 Million

Comparison of Treasury Applications in Four Dimensions

To intuitively understand the scope of the core development team’s strategic adjustment for 2026, the following presents two years of data across four dimensions:

Data source: Core development team’s publicly released proposal documents

Leios Technical Breakdown

Leios’s significance to Cardano is not just an ordinary protocol upgrade but a fundamental restructuring of the underlying consensus architecture. Currently, Cardano’s transaction processing capacity is about 10 to 15 transactions per second. The Leios introduction of a dual-layer architecture—parallel processing of transactions in input blocks, and ranking blocks responsible for final task confirmation—is expected to boost throughput to between 200 and 1,000 TPS, with a theoretical peak under optimized conditions reaching 10,000 TPS. In terms of multiples, this represents a 10x to 65x increase.

Among the nine proposals, the core development team allocated 62.1 million ADA (about $15.8 million) specifically for Leios-related node upgrades, monitoring infrastructure, and security audits. This is the largest single funding request among the proposals.

Other proposals cover developer experience improvements, Plutus smart contract engine upgrades, Babel Fees economic model enhancements (allowing users to pay transaction fees with assets other than ADA), Hydra and Midgard Layer 2 network routes, and Pogun Bitcoin DeFi access.

Development Progress Fact-Checking

Regarding the current real progress of Leios, there are some noteworthy facts. According to the publicly available development tracker from the core team, Leios remains in the “mid-stage development” phase—specification documents are basically complete, but the testnet progress is only about 24%. This creates a tension with the schedule of “testnet release in June and mainnet launch by the end of the year”: the remaining approximately 76% of testnet development must be completed in less than two months to ensure the June timeline is not delayed. Therefore, while “end-of-year mainnet” remains the official goal, its realization depends on the upcoming technical breakthroughs and collaboration efficiency.

Public Sentiment Clash: Focusing on Delivery vs. Doubts About Motivation

Supporters: Focus Signal as Strategy

The core development team’s decision to halve the application amount is uncommon in the crypto industry context. Supporters believe this indicates Cardano’s shift from “research-driven” to “output-driven.” The team explicitly states in the proposal that future reliance on treasury funds will decrease annually, ultimately aiming for full self-sustaining development costs.

Additionally, pulling resources from projects like Acropolis and concentrating on Leios is seen as a substantive response to previous criticisms of “multi-point development lacking large-scale delivery.”

Some analyses suggest that the halving request may free up substantial treasury capital for other ecosystem projects—such as dApp incubation, marketing, and independent research grants—potentially alleviating concerns about “core development team’s dominance” within the treasury.

Skeptics: Risks of Execution and Motive Debates

Critical voices are clear and well-founded. The most pressing technical concern centers on Leios’s development progress: with only 24% of the testnet completed, whether the June window can be maintained is uncertain. Any delays on critical paths could push mainnet delivery into 2027.

Governance disputes are even deeper. Some decentralized representatives have publicly stated they will vote against proposals, arguing that some proposals direct treasury funds into external fund structures rather than transparent on-chain mechanisms. This arrangement is viewed as lacking oversight and potentially undermining community’s right to know about fund flows.

Furthermore, community interpretations of the “halving request” vary. A more cautious view suggests this may not mean the core team’s commercial income is sufficient to support operations, but rather a preemptive risk-avoidance strategy amid rising community governance participation and stricter treasury approval—shrinking the application size to improve approval chances. Whether driven by strategic awareness or practical pressure, this stance itself has become an important narrative variable in the vote.

Ripple Effects: Treasury Governance Paradigm, Public Chain Competition, and Developer Ecosystem

The restructuring of Cardano’s roadmap impacts far beyond a single ecosystem, warranting analysis on three levels.

First, Benchmark Effect of Treasury Governance Paradigm. Cardano’s on-chain treasury mechanism and decentralized representative voting system remain one of the largest decentralized fund distribution experiments among proof-of-stake chains. When the community rejected a $3.5 million meeting sponsorship proposal with 93% vote, and the core developers voluntarily cut their application to $46.8 million for community approval, this governance behavior provides a highly relevant real-world example for other chains’ governance projects. The boundaries of treasury authority, expenditure standards, and the balance of power between developers and the community are now more concretely exemplified in this vote.

Second, Differentiation in Public Chain Competition. Unlike paths that rely on large token incentives for rapid growth, Cardano’s roadmap opts for a deep technical approach: fundamental restructuring of consensus to solve throughput bottlenecks, rather than short-term Layer 2 patches. If Leios can be successfully delivered by year-end, Cardano will have a technical foundation to compete directly with networks like Ethereum and Solana in DeFi, real-world asset tokenization, and enterprise applications. But delays could see this window squeezed by other chains’ concurrent scaling upgrades.

Third, Turning Point for Developer Ecosystem. Internal research indicates that Cardano’s current developer experience is described as “fragmented,” with high entry barriers causing significant developer attrition. The proposals include a six-month overhaul of development tools, usability improvements for Plutus formal verification tools, and the creation of “cardano-init,” a tool to lower entry barriers. The goal is pragmatic: enabling developers to start building on Cardano without needing a PhD or three months of setup. If tooling improvements and mainnet scaling occur in tandem, 2026 could mark a turning point from “structural loss” to “structural growth” in the developer ecosystem.

Conclusion

When the roadmap’s controversies and expectations are both before voters, what Cardano is writing is no longer just a story of technical upgrades. Nine proposals, $46.8 million, a scaling target set for the end of the year—behind these figures lies a real-time stress test of “how decentralized governance allocates scarce resources.” Whether Leios can be delivered on schedule, whether the treasury can achieve more precise output amid contraction, and whether the community can maintain consensus amid disagreements—all these answers will provide an irreplaceable reference for governance practice in the crypto industry. Regardless of the outcome, the mechanism of entrusting core decisions to community votes is already redefining the relationships among developers, token holders, and protocol futures within Layer 1 ecosystems.
