It's too expensive to put all the data on the chain , High cost , Is there a scheme to store the database directly , Or whether there are courses 、 Books 、 Recommend some ideas , I'll study , Our problem mainly revolves around :
The etheric fang 、 Wave field 、EOS
- The scheme of persistent storage
- The cost of persistent storage
- Historical data retention issues
- Syntax supported by data query ( Except for ID In addition to the inquiry , Whether you can query according to other fields )
In other words, the goods on our platform should support the purchase of virtual currency , How to use blockchain Technology .
Take the answer 1:
First of all, we need to clarify what problems we want to solve with blockchain ?
The advantage of blockchain is to solve the problem of trust , And the price is slow and expensive .
In addition, at present, all blockchains do not support reading and writing databases on the chain , Blockchain is born to solve the problem of database tamperability . Therefore, the feasibility of finding a blockchain combined with database is very low .
If a centralized solution is used , Is technically much simpler ( So it comes down to what problem you want to solve ). Today's cloud technology solutions are very reliable , Completely satisfied 1 2 3 spot .
The first 4 spot , Any traditional database can , There are also many ready-made mall schemes .
