I am voting YES on the proposal Cardano Blockchain Ecosystem Budget: Amaru Node Development 2025.
This proposal directly advances Cardano’s strategic objectives of enhancing decentralization, improving security, and ensuring the long-term sustainability of the network. By supporting the development of Amaru as an independent, interoperable node implementation, it addresses the systemic risk of relying on a single codebase and strengthens the network’s resilience, fully aligned with the constitutional principles of decentralization and robustness.
The initiative is led by a consortium of reputable ecosystem actors — Blink Labs, Cardano Foundation, dcSpark, Sundae Labs, and TxPipe — operating under PRAGMA’s not-for-profit governance structure. The maintainer committee is composed of recognized domain experts, each assigned clear scopes of responsibility. This structure ensures a high degree of technical competence and operational accountability, critical for a project of this complexity.
Moreover, the broader impact of this initiative is significant. Increasing node diversity, improving observability with industry standards, and fostering a more inclusive development environment are critical to enhancing the operational robustness and decentralization of the Cardano ecosystem.
For these reasons, I support this proposal and cast my vote in favor.

- Yes1.2M ₳Rationale
I'm voting YES because a second, Rust-based block-producing node adds vital resilience and removes the single-implementation risk currently hanging over Cardano. The maintainer committee—Blink Labs, dcSpark, Sundae Labs, TxPipe, Cardano Foundation, and Pi Lanningham—has a proven record of shipping high-quality infrastructure, so I trust their ability to deliver. The ₳1.5 M ask is bounded to six months, guarded by a smart-contract escrow and quarterly public reports; if milestones slip, unused funds flow back to the treasury. Rust's efficiency and built-in observability will lower hardware costs for small SPOs and give us better telemetry, while encouraging fresh contributors from the wider Rust ecosystem. Finally, backing PRAGMA alongside Intersect strengthens collaboration rather than rivalry—diverse teams, shared vision, stronger network. Let's fund this pilot, measure its progress, and reassess future budgets based on results.

Fully support the idea of cost effective alternate nodes produced by competent teams in the Cardano blockchain ecosystem.
I vote yes. - Yes1.2M ₳Rationale
I vote YES for this proposal because:
It aligns with the 2025 roadmap approved by DReps, where node diversity is a strategic priority to improve decentralization and resilience.
Amaru reduces reliance on the Haskell node maintained by IOG, strengthening network security and fault tolerance—similar to how Ethereum benefits from multiple independent clients.
The development team is highly reputable, with members from dcSpark, TxPipe, Cardano Foundation, and others. They are also actively coordinating with IOG’s Haskell team to ensure compatibility.
The requested budget of 1.5M ADA (for 6 months) is reasonable, with clear smart contract-based fund management and oversight by PRAGMA.
As an open-source public good, Amaru strengthens Cardano’s infrastructure and invites broader participation from Rust developers.
- Amaru is not just an alternative node—it’s a strategic investment in a more decentralized, robust, and future-ready Cardano.

Tôi ủng hộ đề xuất này vì:
Phù hợp với roadmap 2025 đã được DRep phê duyệt – trong đó “đa dạng hóa node” là ưu tiên chiến lược để tăng phân quyền và khả năng phục hồi mạng lưới.
Amaru giúp giảm phụ thuộc vào node Haskell của IOG, tăng cường bảo mật và khả năng kháng lỗi – tương tự cách Ethereum đã làm với nhiều client độc lập.
Đội ngũ kỹ thuật uy tín, đến từ các tổ chức như dcSpark, TxPipe, CF… và đã phối hợp với nhóm Haskell để đảm bảo tương thích, tránh xung đột.
Ngân sách minh bạch, hợp lý (1.5M ADA cho 6 tháng), có cơ chế hợp đồng thông minh và quy trình giám sát rõ ràng thông qua PRAGMA.
Amaru là mã nguồn mở, phục vụ cộng đồng, giúp củng cố hạ tầng dài hạn và thu hút nhà phát triển Rust vào hệ sinh thái Cardano.
- Amaru không chỉ là một node thay thế – mà là nền tảng kỹ thuật chiến lược để xây dựng một Cardano phân quyền, bền vững và chống chịu tốt hơn trong tương lai.

The Amaru proposal presents a carefully constructed initiative aimed at enhancing Cardano’s node diversity, resilience, and interoperability. While I recognize the merit in fostering innovation and expanding the ecosystem, I must emphasize that any strategic investment must be weighed against our overarching mandate to safeguard Cardano’s long-term stability, treasury health, and scientific rigor.
First, the rationale for developing an alternative node implementation is compelling in principle: improved resource efficiency, industry-grade observability, and broader platform compatibility are undeniably valuable goals. Yet, the current Haskell node’s proven robustness and security over five years set an exceptionally high bar. Introducing a parallel node implementation inherently increases complexity and operational risk, especially when the new codebase is still nascent and unproven at scale.
Moreover, while Rust offers attractive features such as fine-grained memory control and a vibrant ecosystem, it is crucial to rigorously validate that the Amaru node can match or exceed the Haskell node’s security guarantees without introducing new attack surfaces or subtle bugs. The proposal’s emphasis on conformance testing and specification alignment is reassuring, but this process is iterative and resource-intensive. We must be prepared for extended timelines and unforeseen challenges, which could strain resources and divert attention from other critical protocol improvements.
Decentralization is rightly highlighted as a core value, and multiple node implementations can indeed reduce centralization risk. However, decentralization must not come at the cost of fragmenting developer focus or undermining the unified security model that the existing node provides. Our governance approach should ensure that the addition of Amaru is not merely a diversification for its own sake but a strategic enhancement that complements and strengthens the network.
The financial ask—₳1.5 million for six months of development—reflects a serious commitment but also demands scrutiny. Transparency and accountability mechanisms, including the on-chain smart contract and quarterly reporting, are positive steps. Yet, the proposal’s optimistic assumptions about effort and costs must be tempered by the reality of blockchain development’s inherent complexity. We must ensure that contingency budgets are not a buffer for systemic underestimation but a safeguard against genuine risks.
Strategically, the Cardano community must maintain a business-minded discipline. We are custodians of a fixed supply, disinflationary protocol with a treasury that must be preserved to fund innovation sustainably. Supporting Amaru should be framed as a calculated investment with clear milestones, measurable outcomes, and a governance structure that can pivot decisively if progress stalls or risks materialize.
I support the initiative to expand Cardano’s ecosystem and attract new contributors, but I insist that we proceed with rigorous oversight, continuous evaluation, and an unwavering commitment to the protocol’s foundational principles. Amaru’s success hinges not only on technical execution but on our collective ability to integrate innovation without compromising the stability and security that define Cardano’s unique value proposition.

We vote YES because this proposal significantly enhances Cardano's resilience by eliminating the risk inherent to having a single point of failure of only having one node for a modest cost.
Amaru provides diversity, better performance, and improved tooling.
Reputation of the proposing team is high - Blink Labs, dcSpark, Sundae Labs, Cardano Foundation, and TxPipe. - Yes796.1K ₳Rationale
- Diversity in node implementation is good in terms of resilience and adoption
- Excellent team that can deliver
- Cost effective / good ROI
- YesRevoted792.3K ₳Rationale
I voted YES because the Amaru project makes Cardano stronger and more decentralised. Right now, we rely on just one main node (written in Haskell) to run the network. If something goes wrong with that, the whole system could be at risk. Amaru gives us a second, fully working option, built in Rust, a language known for safety, speed, and flexibility.
Having more than one node makes the network more secure and reliable. It also opens the door for new developers and use cases that are hard to do with the current setup. The team behind Amaru includes trusted names in the Cardano ecosystem, and they’ve planned carefully with clear goals, budget, and reporting.
The funding request is fair, ₳1.5 million for six months of work, and includes smart contract controls to make sure the money is used properly. This kind of proposal is exactly what Cardano’s treasury should support if we want a stronger, more resilient ecosystem in the long term.

It is clear the community feels the inclusion of this node is overall beneficial to the Cardano Community. However, administration of the budget is an aspect that needs to be clearly defined prior to a proposal. If the mechanism for administering this budget is not clearly defined, how can we properly determine it is sufficient? This sets a precedent for future proposals to have text that may present promises yet have no means of qualification. In my opinion, the administration of the budget remains one of the best suppliers of confidence within a community, and though I support the project in principle, administration should never be compromised.
- Yes663.8K ₳Rationale
We, the Dutch DRep, vote Yes on the Amaru proposal.
The team behind Amaru consists of trusted and experienced contributors with a strong track record of delivering critical infrastructure within the Cardano ecosystem. Their proposal is clear, transparent, and constitutionally sound, demonstrating a high standard of governance and accountability.
We believe the development of a Rust-based node brings meaningful benefits to Cardano. It strengthens decentralization, enhances interoperability, and broadens the developer base. Crucially, it also provides an independent implementation that can act as a constant cross-check of the existing Haskell node—serving as a form of ongoing audit that improves the security and correctness of both.
In our view, Amaru is a strategically valuable project that aligns well with Cardano’s long-term goals.

I voted yes on Cardano Blockchain Ecosystem Budget: Amaru Node Development 2025.
Node diversity is critical for decentralization and network resilience. Having multiple node implementations increases the network’s robustness, performance, and developer access. The Amaru team's funding request is reasonable, perfectly presented and clearly outlined. Furthermore this initiative strengthens and represents a healthy evolution of the Cardano network. - Yes582.9K ₳Rationale
We support this proposal as it directly addresses a long-standing risk in the ecosystem — reliance on a single node implementation — by funding the development of a modular, high-performance alternative written in Rust.
We believe a second, independently maintained node:
- Strengthens the resilience and fault tolerance of the network
- Expands developer accessibility through modern tooling and better observability
- Reduces hardware costs for SPOs, improving participation at the edge
- Enables platform interoperability with WebAssembly
- Empower Cardano core infrastructure to access to wider talent pool with alternative implementation of a more modern programming language
We also appreciate the proposal’s financial transparency:
- Clearly scoped per team member and responsibility
- Budget guarded by a smart contract with refund logic
- Quarterly public reporting and demo cadence already in practice
SIDAN Lab is also interested in the possibility of expanding works into alternative Hydra node, where our team can participate in maintenance and collaboration in the future.
- Yes579.1K ₳No rationale
- Yes573.2K ₳Rationale
As a DRep in the Cardano ecosystem, I vote Yes for the Amaru proposal due to the following key reasons:
Node Diversity and Decentralization: The Amaru project addresses a critical need in the Cardano network by introducing a new block-producing node written in Rust. This increases resilience by reducing dependency on a single Haskell implementation, thereby enhancing the network's fault tolerance and decentralization.
Performance and Efficiency: Amaru prioritizes better resource usage, including lower memory consumption and enhanced observability through industry-standard monitoring. This improvement benefits Stake Pool Operators (SPOs) by lowering hardware requirements, ultimately reducing operational costs.
Enhanced Interoperability: The Rust-based approach not only attracts a wider pool of developers but also integrates seamlessly with existing blockchain solutions. This modular and flexible design expands the potential for future innovations and use cases within the Cardano ecosystem.
High Assurance and Robustness: The development process of Amaru includes thorough conformance testing and the identification of inconsistencies in existing implementations. This meticulous approach contributes to the network's overall security and stability.
Responsible Budget and Governance: The proposal demonstrates financial responsibility with a clear breakdown of Full-Time Employee (FTE) requirements and contingency planning. Moreover, the use of an on-chain smart contract for budget administration ensures transparency and accountability.
Community-Driven and Open-Source: Amaru's open-source model, managed by PRAGMA—a reputable multi-entity effort—ensures community engagement and long-term maintenance. Regular updates and demos foster transparency and maintain community trust.

I'm voting Yes on the budget for Amaru since the development of an additional node is one of the most crucial projects for Cardano to become truly decentralised and not be dependent on a single development team anymore. The Amaru team is highly qualified to realise this and the budget not being administrated by Intersect is a massive advantage. Moreover, a detailed budget proposal for one and only one project is exactly how I want treasury to be handled.

A Rust node will be very valuable to our ecosystem, and node diversity is a crucial step that needs to be taken very soon. This team is promising and I'm confident they will deliver.
- Yes338.2K ₳Rationale
I'm voting 'yes' on this budget. The developers that will be funded from the treasury withdrawal after the possible approval of this budget are well known, highly capible, and accountable. The proposal iteslf is something that the Cardano community has desired for quite sometime. It offers node diversity, by creating a much needed alternative to the Haskell node. I also believe this is how a budget should be approved, it should be smaller items, and not a large budget that included a huge amount of unrelated proposals. When you vote 'yes' on this budget, and the treasury withdraw you are not required to fund other proposals that you don't find as valuable. I also hope to see this node require less resources so that it's easier for people to run cardano-node. The resource consumption on the node has been gradually increasing year after year, and it's not slowing down anytime soon.
