Share a brief history of your project and organization

I joined the filecoin network in 2021, and made the cc package of fil at the very beginning.  In 2022, we did a part of cc to dc conversion, and now we have a planned continuous development of data storage.

Is this project associated with other projects/ecosystem stakeholders?

No

Describe the data being stored onto Filecoin

The Sloan Digital Sky Survey (SDSS) is one of the most ambitious and influential surveys in the history of astronomy. 
The SDSS project has established in 2000, five periods, 18 times data released. The 19th DR will be in 2024. 
As for now, there are about 750TB volume of data can be accessed.  5.5 million directories, 400 million files. 
DR1-DR7: SDSS-I, 2000-2005; SDSS-II, 2005-2008), it obtained deep, multi-color images covering more than a quarter of the sky and created 3-dimensional maps containing more than 930,000 galaxies and more than 120,000 quasars.
DR8: contains all images from the SDSS telescope - the largest color image of the sky ever made. It also includes measurements for nearly 500 million stars and galaxies, and spectra of nearly two million. 
DR9 contains the first release of BOSS spectroscopy to the public as well as several significant updates to the cumulative SDSS archive
DR10 contains the first release of APOGEE infrared Galactic spectroscopy as well as cumulative updates to the BOSS optical extragalactic spectroscopy archive
The SDSS began regular survey operations in 2000, after a decade of design and construction.  It has progressed through several phases, SDSS-I (2000-2005), SDSS-II (2005-2008), SDSS-III (2008-2014), and SDSS-IV (2014-2020).  Each of these phases has involved multiple surveys with interlocking science goals.  The three surveys that comprise SDSS-IV are eBOSS (including SPIDERS and TDSS), APOGEE-2, and MaNGA (including MaStar),
The SDSS-V Pioneering Panoptic Spectroscopy program started observing in October 2020, and consists of three surveys, known in SDSS-V terminology as mapper programs.

Milky Way Mapper is a multi-object spectroscopic survey to obtain near-infrared and/or optical spectra of more than 4 million stars throughout the Milky Way and Local Group
Local Volume Mapper is an optical, integral-field spectroscopic survey that will target the Milky Way, Small and Large Magellanic Clouds, and other Local Volume galaxies
Black Hole Mapper is a multi-object spectroscopic survey that emphasizes optical spectra (often also with multiple epochs of spectroscopy) for more than 300,000 quasars

The data of this website is about 650TiB. You requested a total of 8PiB, 8 backups, and a single data set size of 1024TiB. It seems too much.Can you reduce the total amount you requested?

[usejsi]

We have adjusted it according to your request, thank you

[TOPPOOL-LEE]

Could you list the technical solutions in detail? Could you list the names of your cooperating sps, geographical locations and companies? Are you sure you can support Spark?

[usejsi]

I hope we are close to getting approval. We have developed our own technical solutions, including some crawlers, cutting tools, etc. The SPs we cooperate with are mainly fund companies, large customers and independent investors. Some friends who previously mined BTC contacted us and hoped to join Filecoin. Spark can be supported, thank you.
