Private cloud blockchain storage

1. In short, the data of the blockchain is formally stored in the blockchain through the formula algorithm process of the block. All nodes in the whole network express that they accept the block, and the way to express acceptance is to make the random hash value of the block the latest block hash value. Xingqun manufacturing will be extended based on the blockchain.

2. How to store information on the blockchain: call the API provided by the blockchain platform

generally, the blockchain platform will provide corresponding interfaces, such as RPC, json-rpc, HTTP, etc. of course, the platforms are not the same, and the degree of friendliness is different

some companies specializing in API, such as blockcypher, can provide friendly calling interfaces, and it is not very convenient to write answers on the mobile phone, Search below

as for the storage content, add a point: in addition to the conventional cloud storage, file entities on the file hash record chain also have blockchain based storage schemes, such as IPFs, storej and so on

3. Cloud computing storage can be used as the lower layer of blockchain. Cloud computing or cloud storage is infrastructure, which can be understood as a new generation of computer (or hard disk), while blockchain can be seen as a business oriented accounting system (or a trusted database) that can be built based on Cloud Computing (cloud storage).

4. 5GH cloud storage ecological chain has been put on the currency tiger exchange. After passing the advanced certification, it can be sold in the currency tiger exchange in about 30 minutes, and it can be realized successfully
the airdrop activity of 5GH cloud storage ecological chain is still going on. Register and pass the real name certification, get a mining machine, sell it for 2 yuan and log on to the exchange, invite to get more revenue and promote it as a team!

5. Big data and blockchain are two independent things, which do not have to be used
in fact, only high-level security data can be used for blockchain development, and most companies do not have this requirement. It can be understood that there are so many companies in the world, only a small part needs to use big data technology, and a smaller part needs to use blockchain technology. These two parts can intersect but do not include
for companies that normally use big data, there are non relational databases like HBase, mongodb, hive, Mr, spark and so on in terms of storage and processing, which have nothing to do with blockchain.

6. DGC is really unreliable. It's been 20 days since the withdrawal. I think it's really unreliable. Sorry to die

7. NAS is also called "network memory" because it is connected to the network and has the function of data storage. It is a special data storage server. It takes the data as the center, completely separates the storage device from the server, centralizes the management of the data, so as to release the bandwidth, improve the performance, rece the total cost of ownership, and protect the investment. Its cost is much lower than using server storage, but its efficiency is much higher than the latter. NAS is a hardware architecture with CPU + memory + storage + network, as well as an independent operating system. It's like a super micro computer. It's undoubtedly a good thing for developers of play technology, but for ordinary families, it's a little complicated to operate, and it doesn't use NAS function to the essence, In fact, choosing some wireless mobile hard disks can meet the needs of common families to share storage and data, and the price of wireless mobile hard disks is not so high. Previously, crowdfunding bought a "private cloud" and thought it was OK. The main reason is that the operation is simple and easy to understand. The elders at home can use it. They can basically use it by playing wechat.
