I would like to save daily prices of about 3000 items (about 2mb in size) on a public blockchain, and I would like to create a DAPP to retrieve the data. I am considering saving the data on Ethereum. I checked this link which said it would cost around $76000 to save about 1 GB worth of data, which is very expensive for me. Is Ethereum the right choice for this type of use case? Or Should I consider something else? Any suggestions?

  • The answer to this question will be divided into "Use Ethereum" by anyone who has Ether and "Use something else" by all the rest. – goodvibration Dec 02 '19 at 13:39
  • I am very new to blockchain, and I don't even know what alternatives exist. I just would like to know if Ethereum is good for this type of use case, or if not, any suggested technologies or platforms that I should consider. – Pongal Dec 02 '19 at 13:43
  • Depends on: 1. your requirements (e.g., how fast you need to be able to fetch the data from where it is stored). 2. your resources (e.g., how much money you're willing to spend on writing/updating the data). – goodvibration Dec 02 '19 at 13:47
  • Time is not an issue, I will be saving the data once in a day. So, after I save the data on the blockchain, I can wait up to an hour if necessary for the values to be retrieved on the DAPP. 2. Ideally, I don't want to spend any amount on saving the data, but since it is not possible on Ethereum, I would like to spend as minimum as possible. The data I will be saving is for public service, sort of like charity.

  • Would you be able to compress this data into a small chunk? – goodvibration Dec 02 '19 at 13:52
  • These are prices of about 3000 items. I want to save them in a map on the Smart Contract. – Pongal Dec 02 '19 at 13:55
