We understand that time is valuable and reading through the entire project can be time-consuming. Therefore, we have prepared a summary (items below), complete with pictures.
1/Challenge: High server costs, limited internet access, and growing Cardano complexity hinder #Cardano SPOs. We aim to tackle these challenges and provide a solution that benefits both underprivileged SPOs and those seeking to optimize costs. See the graph (RAM vs VPS Cost)
2/Solution: We propose acquiring bare metal Amazonian Solar-Powered linux ubuntu servers through Fund10, which will run on the infrastructure of our registered IT company in Brazil. In addition, we will subsidize the internet costs. By joining us, SPOs will contribute to decentralization within the ecosystem, as our pool (ADABR) currently stands as the sole representative in the Amazon region. Access to the servers will be like a regular VPS server over ssh.

3/The community's Fund10 contribution will provide the subsidy to set up the structure and computer network specially for the project, which is simple. In return, we will offer maintenance and infrastructure, including company facilities, internet entreprise link and clean energy. We operate today ADABR Pool linux servers, and a mining farm with 30KW + 10,8KW on solar panels. See pictures below about where we are sited (Belem-PA-Brazil).

4/SPOs will only be responsible for the cost of the VPS internet link, which we'll strive to keep as low as possible. This aspect of the project has faced criticism, but it needs to be sustainable in the long run. As a potential solution, we propose sharing IP ports to divide the IP costs among users, reducing cost to less than 50 ADA/month (16 USD). The 16 USD price is final, it is currently around 50 ADAs. However, if the ADA price increases due to volatility, the value will always be approximately in USD, according to the monthly exchange rate. Nonetheless, we will only receive payment in ADA to encourage adoption. Furthermore, as we have some "skin in the game," this received value in ADA will be converted into the ADABR pool pledge.
5/Despite being located in the Amazon, our internet connection is highly stable, you can check our 24h-uptime on https://cexplorer.io/pool/pool1z97uz9kzzfdekjjrmxvslvxzyj9jep6thf4he5qtmcdaqvznl8c/about#data anytime. Additionally, the region's proximity to Central America and a four-hour flight to the USA provides convenient access.
6/This project ensures server redundancy & fail-safe measures for uninterrupted operations. Dual power supplies, RAID storage, multiple internet links, and continuous monitoring guarantee a highly resilient infrastructure.
7/Our initial goal is to serve a minimum of 5 SPOs with this server setup. However, if there is higher demand, we are committed to utilizing our own resources to accommodate it, in addition to the support provided by FUND10. As a small initiative, our participation in FUND10 aims to contribute to the regional development of the Amazon while addressing centralization concerns. Nevertheless, we are eager to independently expand and grow beyond these boundaries
Please proceed below with the full text of our project.
------------------------
The primary issue at hand revolves around the exorbitant costs associated with dedicated cloud or bare metal servers that meet the minimum requirements of the Cardano network. Currently, these requirements entail a minimum of 24GB RAM, 250GB SSD HDD, and a minimum two-core CPU. In Brazil, the price range for such servers fluctuates from approximately 200 USD to as high as 1500 USD on AWS EC2 instances, rendering them unaffordable for many Cardano Stake Pool Operators (SPOs). Despite pool rewards amounting to around 340 ADA every 5 days, SPOs often find themselves having to operate at least 3 servers, some even paying to stay active, with non-block producing pools all epochs.
To overcome this challenge, we propose an alternative approach. The project aims to procure reliable, high-end servers (proposed tech spec for multiple instance support: Intel® Xeon® Gold 5416S 2G, 16C/32T or similar; 128GB RDIMM, 4800MT/s Dual Rank; 4TB SSD RAID) specifically designed to operate with 99.9% uptime, utilizing solar energy as a sustainable power source. By capitalizing on solar energy and leveraging the infrastructure of or company facilities, operated by ADAZUL Pool (adazulpool.com), we can provide VPS servers at a significantly reduced price, as low as possible, our target is set to be less than 50 ADA/month.
In addition to the cost advantage, this project will ensure servers with fixed IP addresses and ports, running Ubuntu Linux and allowing SSH connections over the enterprise internet link we work on, thus guaranteeing the stability and reliability of the infrastructure. By offering affordable and sustainable server options, we aim to empower SPOs with the necessary resources to operate efficiently and contribute to the growth of the Cardano network, which currently faces escalating demands for more powerful hardware.
Through this solution, SPOs can optimize their financial expenditures, enhance their pool performance, and expand their operations. As a result, it promotes the decentralization and resilience of the Cardano blockchain.
Redundancy proposal: this project has a robust redundancy and fail-safe plan to ensure uninterrupted operations. Each server will be equipped with dual power supplies, connected to separate power sources to prevent single points of failure. In the event of a solar system failure, our servers will seamlessly switch to the backup power supply without disruption.
Furthermore, we'll implement RAID (Redundant Array of Independent Disks) configurations for data storage, ensuring data integrity and protection against drive failures. Regular backups will be performed to remote off-site locations, providing an additional layer of security in case of any unforeseen incidents.
Regarding internet connectivity, we'll have multiple redundant internet links from different service providers. If one link experiences issues, the traffic will automatically switch to another link, maintaining stable and reliable internet access for our servers.
Additionally, we'll set up monitoring systems to continuously monitor server performance and health. Automated alerts will be in place to notify us immediately of any potential issues, allowing us to take swift actions and minimize downtime.
Overall, our goal is to establish a highly resilient and reliable server infrastructure, ensuring maximum uptime and data availability for the benefit of our users and the Cardano community.
Currently, we utilize only a fraction of our installed solar capacity, which amounts to 40.8 kW in solar panels. Our current energy consumption, including the ADAZUL servers and 11 NVIDIA series 30 GPUs installed across 4 computers, has a nominal power of 1800W, totaling approximately 1296 kWh/month. The solar panels generate an average of 4000 kWh/month, and the surplus is stored as credit with the energy distributor. In addition to running the ADAZUL stake pool, we are also involved in Ergo mining, a partner network of Cardano, and intend to maintain this infrastructure.
The uniqueness of this solution lies in its combination of affordability, sustainability, and reliability. By providing high-end servers powered by solar energy at a significantly lower cost compared to existing options, this project target audience are specifically the Cardano Stake Pool Operators.
Cardano will benefit from this solution as it addresses the cost barrier that presently hinders the participation of numerous SPOs. By offering accessible servers that meet the network's requirements, it enables a greater number of SPOs to actively contribute to the decentralized operation of the Cardano blockchain.
The importance of this solution to Cardano arises from the necessity of establishing a robust and diverse network of SPOs. As the demand for more powerful hardware increases, it becomes crucial to reduce entry barriers and make server infrastructure more affordable. By doing so, we foster inclusivity, encourage broader participation, and bolster the network's resilience and security.
To demonstrate the impact of this project, transparent documentation of the cost savings realized by SPOs who adopt these servers will be provided. Additionally, the increase in the number of active SPOs and their contributions to the Cardano network using the infrastructure will be noted.
Overall, this solution effectively addresses a critical problem, presents a unique approach and aims to empower SPOs to contribute effectively to the network's clean energy growth and decentralization.
The proposed solution directly addresses the challenge of high costs associated with acquiring dedicated servers for Cardano Stake Pool Operators (SPOs). By offering reliable, VPS servers powered by solar energy at a significantly lower price, the solution enables SPOs to meet the minimum requirements of the Cardano network while reducing their operational expenses. This approach empowers SPOs to operate efficiently and contribute to the growth and decentralization of the Cardano ecosystem.
The benefits of this solution to the Cardano ecosystem are multi-fold. Firstly, it eliminates the cost barrier that prevents many SPOs from participating, allowing a greater number of Cardano users to actively engage in operating stake pools. This increased participation enhances the decentralization and security of the Cardano blockchain.
Secondly, the use of sustainable energy sources, such as solar power, aligns with Cardano's commitment to environmental responsibility. By promoting the adoption of eco-friendly practices within the network, the solution contributes to the long-term sustainability of Cardano's operations.
Thirdly, the provision of stable and reliable server infrastructure ensures uninterrupted operation, reducing downtime and improving the overall performance of the Cardano network. This increased stability enhances the user experience, attracting more users and stakeholders to the Cardano community.
What are the exact specifications for each individual SPO allocation? Each SPO allocation will consist of one server instance per request, with hardware requirements in line with the latest version of the Cardano node on GitHub. To preserve decentralization, we do not aim to provide multiple servers to a single SPO. Additional servers (relay and/or block producers) are recommended to be sourced locally or through known cloud services.
How many SPOs do you intend to service with this server setup? Our initial goal is to serve a minimum of 5 SPOs with this server setup. However, if there is higher demand, we are committed to utilizing our own resources to accommodate it, in addition to the support provided by FUND10. As a small company, our participation in FUND10 aims to contribute to the regional development of the Amazon while addressing centralization concerns. Nevertheless, we are eager to independently expand and grow beyond these boundaries.
The project's impact extends beyond funding the project team. It contributes to the growth of the Cardano ecosystem by expanding the network of active SPOs, strengthening the infrastructure, and fostering a more inclusive and sustainable community over Brazil's Amazon ground.
Quantifying the impact within a reasonable timeframe is dependent on several factors, including the adoption rate of the solution by SPOs and the overall growth of the Cardano network. However, it is realistic to anticipate an increase in the number of SPOs due to the reduced costs and improved operational efficiency provided by the solution. This, in turn, will contribute to a more robust and decentralized Cardano ecosystem.
By tracking the number of SPOs adopting the solution, the increase in active stake pools, and the overall growth of the Cardano network, we can quantify the project's impact. Additionally, monitoring user feedback, transaction volume, and community engagement will provide further insights into the value this solution brings to the Cardano ecosystem.
In conclusion, the proposed solution addresses the challenge of high server costs for SPOs, brings numerous benefits to the Cardano ecosystem, and aligns with Cardano's core principles of decentralization, sustainability, and user-centricity. Through increased participation, improved stability, and reduced operational expenses, the solution fosters a stronger, more resilient Cardano ecosystem that attracts and empowers a diverse community of stakeholders.
The success of the project will be measured through a combination of quantitative and qualitative metrics that demonstrate the benefits brought to the Cardano ecosystem.

About Adazul Pool: Adazul [ADABR] was established in 2021 (pool ID: pool16pg8zc9zxxfjksquvjs6ljxuy8ng9xf79ekqekap98a8wjzuttg) and successfully mined a total of 171 blocks. However, due to the bear market and high server costs, the pool was temporarily retired. Nevertheless, with the collaboration of Victor Grecia and a new partnership, we breathed new life into Adazul by utilizing a bare-metal infrastructure previously employed by his CRIP pool, which had retired at that time and joined forces with Adazul. This historical context served as inspiration for our project idea of a cost-effective server infrastructure.
Currently, Adazul (Pool ID pool1z97uz9kzzfdekjjrmxvslvxzyj9jep6thf4he5qtmcdaqvznl8c) is undergoing restructuring, and we are actively investing in its growth. Our Twitter (https://twitter.com/adazulpool) and Telegram (https://t.me/adabrpool_ptbr) communities are highly engaged. Once the new parameters, fator k, and minpoolfee come into effect, we are confident that we will be among the validating pools for emerging blocks.
Thank you for your interest and support in our endeavors. We are dedicated to contributing to the Cardano ecosystem and fostering its decentralization.
