@Epengtimes Hi,

1. Please provide the detailed organization name by using the language of your country.
2. Please provide website and social media of organization or project. If you don't have a social media account, you can provide other related reports links.
3. Please provide more data samples to indicate you have 5 PB data already.

[Sunnyiscoming]

Any update here?

[Epengtimes]

@Sunnyiscoming , sorry for late. our name is EPENG TIMES TECHNOLOGY LTD, incorporated in Cayman Islands. we have office in Singapore. I can provide company registration material if needed. As we don't have to C business, no PR requirement so there is no website or other links can be provided.

we don't have 1 PiB raw data in hand ( 5PiB DataCap takes 1 PiB raw data generally), since we don't have the capacity to store so huge data. that is the reason for DataCap application. based on our business requirements, we have PiB scale raw data this year.

[Sunnyiscoming]

@Epengtimes I think Datacap is set up for an existing dataset. So I want to know how much data you have?

[Epengtimes]

@Epengtimes I think Datacap is set up for an existing dataset. So I want to know how much data you have?

@Sunnyiscoming There are about 500TiB raw data need to be sealed into Filecoin now. And will be another 500 TiB new data in next 3 months as the increasing rate is about 170TiB/month, thanks!

[Sunnyiscoming]

@Epengtimes Sorry for slowly update. You should adjust the Total amount of DataCap being requested from 5PiB to 500 TiB, because Datacap is set up for an existing dataset.

[Sunnyiscoming]

Otherwise, please provide the proof of organization existence, and to provide more data samples and detailed data source to prove you have 5 PB data already.

[Epengtimes]

@Epengtimes Sorry for slowly update. You should adjust the Total amount of DataCap being requested from 5PiB to 500 TiB, because Datacap is set up for an existing dataset.

@Sunnyiscoming, thanks for response!

1. Based on LDN guidelines, clients will store up to 10 replicas of each piece of data to keep data safe. 500TiB raw data need 5 PiB DataCap at most.
2. Anyway, both 500 TiB and 5 PiB DataCap are fine to us. The problem we are facing is that the LDN process is out of control. This application was created 2 months ago, and there are only 2 round communications in 2 months. we really can't put resource on unpredictable things.
3. As I mentioned before, we can provide company registration material. If needed, we can schedule a video conference to check those materials with you.

[Sunnyiscoming]

I will talk about that with governance team. Hope to solve your problem quickly.

@Epengtimes thanks - your application is still missing a client address. Will you be using the same one?

Separately, I'd like to understand your SP selection mechanism a bit better. Here are the stats from your deal distribution: https://filplus.d.interplanetary.one/clients/f01624861/breakdown (please let us know if this is not right).

From what I see in your dealmaking, a majority of your data is stored with these 4 SP IDs:

1. f01602479
2. f01606675
3. f01606849
4. f01641612

For these 4 SPs, some things I noticed:

• each of their peer IDs points to an IP address that is coming from the same node / ISP / datacenter.
  • https://filfox.info/en/peer/12D3KooWSnGRBafbH3YSijHYGA2gUKUptvWZv86haYMp8uLzPJxZ - 67.212.82.9
  • 
  • https://filfox.info/en/peer/12D3KooWJfAU7HD3VBZNPNnKoxiVu35TqRbqKA9AUW9dMAzJCXJ8 - 209.44.107.2
  • https://filfox.info/en/peer/12D3KooWKYHntwN2gtXY583w5mZAdgiyzhy1bDFsSGJ1feebHr9o - 184.170.135.169
  • https://filfox.info/en/peer/12D3KooWHQNHVg1mromrA25LGRcRFfj44Eq5rC7N1CKsxpFPLy21 - 68.71.48.185
• each of their creation patterns is basically identical - please see message history for owner IDs on chain
  • every single one was initiated with the 0.1 FIL on the same date
  • every single one changed owner address the same date
  • every single one has withdraw balances on the same date

This leads me to believe that they are likely owned by the same entity. Is that not accurate? How did you find these SP IDs?

I'd like to see some details on your plan for this. Which SPs do you plan to work with now that you've already made several deals on chain and want to store 10x replicas for your data?

We will distribute deals faily among miners in all regions.

@Epengtimes , waiting for a response. If we don't hear back by Friday, we might have to close the issue.

[Epengtimes]

Hi @dkkapur @raghavrmadya The 4 major SPs are operated by the same technical team, I am not sure if owned by the same business entity, they were introduced by our BD team.

We are trying to find more distributed SPs to store our data. It's difficult to find very appropriate partner for this, because need much workload for cooperating , also need good network condition between us, our team is very busy in production business, so the process is slow.

And as backup&archive , we think the major 4 SPs are safe enough, also got proof in the past year.

For the plan for this batch, we'd like to use these 4 SPs to start, and continue find more SPs, if this is inconformity to the rule, we could close this application temporary, and will re-open when we have good SP partners.

Thanks!

[raghavrmadya]

Storing all copies in potentially the same location/data center defeats the point of decentralized storage, even if you are dealing with 4 different storage providers. We would either recommend finding providing proof that the copies are not being stored in the same location or finding other SPs that are more diverse.

[raghavrmadya]

Please let us know how you would like to proceed and we can either close this app or wait for you.

[raghavrmadya]

@Epengtimes , closing this application as per your suggestion. Please re-open with good SP partners. You can always reach out to SPs on Filecoin Slack, BigDexchange, and Filgram. Please make sure to link this application when you open a new one to move forward quickly.

Thanks
