@MaleiWong I am very happy to see your application. Please answer these questions: If you are a data preparer, how will the data be prepared? Please include tooling used and technical details?

[MaleiWong]

@MaleiWong我很高兴看到你的申请。请回答以下问题： 如果您是数据准备者，将如何准备数据？请包括使用的工具和技术细节？

We carry out secondary development based on https://github.com/karust/gogetcrawl. After downloading a batch of data from Amazon Web Services S3, it will automatically process the packaging and generate the car file. As long as the same download parameters are set, it can be downloaded and Generate car files with the same piececid to ensure that different SPs can download and encapsulate the same file to ensure that the data backup meets the requirements. After the car file is generated, a corresponding unit data will be generated at the same time, including filename, data_cid, piece_cid, piece_size and other information and written into the csv file. The csv file is the datacap distribution file that will be used later, and the file name is the downloaded The marker name and starting position of the dataset. Based on the metadata file, you can tell which portion of the total data set is saved by each LDN. The data download can be executed directly on the SP's device, or we can mail it to the SP through the hard disk after processing.

@MaleiWong The amount you apply for every week is too large. Why do you apply for 1PIB? Do you have data processing experience? Can you comply with the rules of FIL+? How to ensure that DC will not be abused?

@MaleiWong The amount you apply for every week is too large. Why do you apply for 1PIB? Do you have data processing experience? Can you comply with the rules of FIL+? How to ensure that DC will not be abused?

DataFortress boasts a team of 20 technical experts who are dedicated to exploring the IPFS and Filecoin domains and possess extensive experience in distributed storage and computing. 2 years of experience in DC data processing.

In v3.1 we wrote weekly requests as 1PiB. But there was only 512TiB in the first round. Therefore, this time we also write the weekly application as 1PiB. We will adjust weekly applications to 200-300TiB in the future.

Compliance is very important. The core of DC is to bring precious data storage assets to Filecoin, which is what we have been pursuing. We have written down our work process in detail in the application form, and you can also download our data to view at any time. We hope to be treated with kindness, thank you.

[nicelove666]

Sorry, the quota of 1Pib in the first round is still too much. Although I understand your statement, you think that writing 1Pib in the first round may only be 512Tib, so the first round you want to get is 512T.

I suggest you close this ldn and reapply. The weekly application is recommended not to exceed 300T.
