目標：1.ハードウェアを作る(試作機開発)2.ビジネスモデルを提案する
［問題点］現在、ラズベリーパイ４のメモリースペックが８GBであり、ステークプールを運営するにはメモリーが１６GBほどのスペックが必要になっている。不要な機能が含まれているため、さらに最適化する必要がある。
[解決策]ラズベリーパイを増強したような小型でエコな電力で動かすことができるステークプールオペレーター専用のハードウェアを開発します。

[運営資金詳細]
開発費用（会社選定中、見積もりは5万～８万ドルで出てきている）：6万ドル
エンジニアメンバー人件費（1年間×４名）：4万ドル
（税金30％で計算）

[活動内容]
私たちは日本のﾌﾞﾛｯｸﾁｪｰﾝEXPOをきっかけで集まり、エンジニアの仲間と話し合っている時にラズベリーパイ４のスペックの限界が近づいている現状を知りました。ラズベリーパイはとてもエコでSPOを費用面から支え、さらには消費電力がとても少なく世界の環境にも配慮し、エコで持続可能性なカルダノをさらにサポートする素晴らしいコンピュータです。このコンピュータでは2021年12月現在、前回の更新でほぼブロック生成ができなくなってしまいました。その現状を克服したいと思っています。VPS（レンタルサーバー）はSPOの負担が大きく、多くの委任が得られているステークプールならばコストの負担を賄える報酬が得られますが、小規模プールではコストを払うことができずにプール運営を辞めていくオペレータもいます。例えば、リレーノードの２つのうち１つをラズベリープロジェクトで開発したSPO専用のハードを使ったり、年間に１ブロックでも収益を得られるようなランニングコストの低いものが出来上がれば、世界に2021年12月現在約3000プールあるものがさらに数千、数万のプールを増やすことができ、カルダノエコシステムをハード面から増強することができます。私たちは2021年10月から4人でDAOを結成し、すでにプロジェクトは進んでおり、ボードの選定やスペックの検証、開発企業との打ち合わせを行っております。さらには私、ダウはこのプロジェクトを成功させてCardanoDAOの成功事例として世界に発信したいと思っております。そのため、メンバーはﾌﾞﾛｯｸﾁｪｰﾝ開発者や組み込みのスペシャリストで構成しておりますが、ボランティアではなく、プロに払うには少額にはなりますが報酬を渡していきたいと思っております。そのため、４名の１年間の報酬も費用に含めております。
このプロジェクトはSPO専門のハードとして、16GBに増強し、ラズベリーパイ４で不要であったBluetoothなどを除き、消費電力を抑えたハードの試作機を完成させるのを目標に致します。
試作機が完成した後、どのようにハードをみなさまに届けるのか、開発を行い見定めていきます。
応援、ご協力、投票よろしくお願いいたします。

[Activity content]
We got together at the Blockchain EXPO in Japan, and when we were discussing with fellow engineers, we learned that the limits of the specifications of Raspberry Pi 4 are approaching. The Raspberry Pi is a great computer that is very eco-friendly, supports SPO from a cost perspective, consumes very little power, is environmentally friendly, and further supports eco-friendly and sustainable Cardano. As of December 2021, this computer is almost unable to generate blocks in the last update. I want to overcome that situation. VPS (rental server) has a heavy burden on SPO, and if it is a stake pool that has a lot of mandates, you can get a reward that can cover the cost burden, but in a small pool you can not pay the cost and pool operation Some operators are leaving. For example, if one of the two relay nodes uses the SPO-dedicated hardware developed by the Raspberry Project, or if a low running cost that can generate profits even by one block per year is completed, it will be December 2021 in the world. What currently has about 3,000 pools can be expanded to thousands or tens of thousands of pools, further enhancing the Cardano ecosystem from a hardware perspective. We formed DAO with 4 people from October 2021, and the project is already in progress, we are selecting the board, verifying the specifications, and having a meeting with the development company. Furthermore, I, Dow, would like to make this project a success and send it to the world as a successful example of Cardano DAO. Therefore, the members are block chain developers and built-in specialists, but I would like to give a reward, although it is a small amount to pay to professionals, not volunteers. Therefore, the one-year remuneration for four people is included in the cost.

This project aims to complete a prototype of hardware with reduced power consumption, excluding Bluetooth, which was unnecessary for Raspberry Pi 4, by increasing it to 16GB as hardware specialized for SPO.

After the prototype is completed, we will develop and determine how to deliver the hardware to everyone.

Thank you for your support, cooperation, and voting.

Summary

This month, our team has ordered the first prototype board, which is the milestone of this project. We started inspecting the machine and confirming its operation. 　This time, we designed and ordered 2 board manufacturers who cooperated with our project, and produced 3 prototypes. Our x86 board has arrived. Currently, the operation of the board is checked by hardware and software. I am in the process of implementing it from both. Since it is a prototype, various problems have been found. However, these problems are expected to be resolved during mass production. 　In the future, factors such as performance when running Cardano, power consumption of the board, and cost during mass production We will conduct an evaluation regarding We will continue to work with board manufacturers to carry out projects.

Summary

This month, our team will start manufacturing the first prototype board, which is the milestone of this project. For this reason, we made various adjustments with the board manufacturing company and ordered the prototype board. Two of the four companies we contacted last month were interested in our project. rice field. Each company has its own specialty in terms of cost, function, power consumption, board size, etc. Both companies have the development capabilities to manufacture attractive boards for SPO. In order to finally select one of the two companies, we ordered boards from each company and actually decided to evaluate. Order processing for prototype boards has been completed and is currently in the shipping phase and We now have. As soon as the board is in the hands of the team, the performance, power consumption, and mass production cost of running Cardano will be reviewed. Start evaluating with respect to factors such as strikes.

Summary

This month, our team will start manufacturing the first prototype board, which is a milestone for this project. For this reason, we have developed new companies that will undertake board manufacturing. Fortunately, four companies have taken an interest in our project, and we are currently developing and manufacturing boards. We are making adjustments for Both companies have a proven track record in board manufacturing, and the final We plan to select one company out of four. However, as a common problem for each company, due to the worldwide shortage of semiconductors, the production of semiconductor chips Procurability is very poor, and it is an important point of discussion whether the board specifications can be fixed at the time of mass production. concrete have different chip model numbers and revisions depending on the production lot, or in the worst case, different manufacturers. The problem is that the case is assumed. This translates directly into development, manufacturing, support costs, etc. We need to consider this matter carefully because it is a serious matter. We also reviewed the board specifications. We are designing a board that adopts the new generation ISA. Although the project has been advanced with a needle, Cardano's design concept, CPU performance, stable supply, platform Given the maturity of the form, the ISA has changed course to adopt the widespread x86-64. rice field. We are currently reviewing the board specifications.

Summary

Project Raspberry develops dedicated hardware for stake pool operators that is very small and eco-friendly. By developing hardware with low initial introduction costs and low maintenance costs, there are currently more than 3,000 pools in the world, but even very small pools can be monetized, which will spread in developing countries. We can send in the hardware.

Summary

Our project requires a lot of money. Unless at least half of catalyst's funds are in our hands, it is difficult to contract with a company to develop hardware. Furthermore, the global shortage of semiconductors has become a problem, but we are now doing what we can with a small amount of money. At Blockchain EXPO, we will exhibit about our project. The leader, DOW, appealed to a large audience.

Summary

As for the current progress, we are now in the process of designing the hardware and selecting a company. Regarding this progress, we exhibited at the Cardano booth at the Blockchain EXPO, which was attended by tens of thousands of people at Tokyo Big Sight. Five hardware specialists from the project also traveled to the venue to provide explanations as the project's exclusive explainers. The leader of the project, the DOW, gave a presentation on the project. A press release will be issued in the future. In addition, we are meeting with companies to discuss the project.Th
