How normal is the fluctuation of miner's calculation force
although bitcontinent is not a good bird, it is suggested that the risk tolerance should not touch mining
ordinary retail investors should remember to stay away from the mining link of ASIC miner. The water in it is too deep. How can you play with it
this is the way to buy a futures miner. When you buy a futures miner, you should not only look at the profits at that time, but also predict the fluctuation of the middle currency price and the sharp rise of the calculation power

these are illusory things, so work hard!

For example, when many enterprises choose servers, they will consider the difference between blockchain servers and traditional servers? The following is a brief analysis
to be exact, the blockchain is a technical model, and the server is a type of hardware resource. There is no contrast between the two. However, if we insist on the difference, we can also see the difference and connection between the two
to say the difference between the two,
the biggest feature of blockchain is decentralization, such as bitcoin, the most typical application of blockchain. Bitcoin is independent of any third party's decentralized currency. There is no centralized issuer. It is generated by the calculation of network nodes. Anyone can run bitcoin client software on the computer to participate in the proction of bitcoin. No matter where they are, anyone can dig, buy and sell bitcoin
all nodes of the blockchain are distributed in different places, and each node is maintained and managed by itself. It does not need centralized construction, but also needs special management and maintenance, which can make full use of idle resources. Due to the distributed characteristics, the system is difficult to destroy, such as bitcoin. Even the most powerful people or organizations in the world can't destroy the bitcoin system based on blockchain
traditional server is centralization service
traditional centralization server, such as WeChat, Alipay and so on, are all responsible for providing services to all clients by the server behind the company, and the client acquires services from the server. If their servers are attacked and paralyzed, then your WeChat and Alipay will not be able to use them. For example, on May 28, 2015, Ctrip was attacked by unknown server, and its web version and mobile app could not be used normally
does the blockchain still need servers
to be specific, blockchain is also divided into public chain, private chain and alliance chain. The essential difference between the three is that they have different degrees of decentralization
that is, the public chain is completely decentralized. The above mentioned bitcoin belongs to the public chain. The private chain and alliance chain are not completely decentralized, and there is still a shadow of centralization
as mentioned above, blockchain is a technical model, and server is a type of hardware resource. The two will inevitably have a combination of applications
for example, the combination of storage type server and blockchain can use cryptography to ensure the security of data transmission and access, so as to make the storage server data more secure
for blockchain server, if you need to know more, you are welcome to consult the 10th power computing power leasing platform
it is recommended to learn about formal P2P networks such as xiaxinrong.com
A: first, block height does not refer to the capacity of the blockchain
Second, the connotation of block heightblock height is the number of blocks linked to the main chain, that is, the number of blocks connected to the blockchain
Block height is the indicator of block2. The block has two identifiers, one is the hash value of the block head, the other is the block height
3. The hash value of the block head is the number obtained by the second hash calculation of the block head by sha256 algorithm
Theblock hash value can uniquely and explicitly identify a block, and any node can independently obtain the block hash value by simply hashing the block head
4. Block height refers to the position of the block in the blockchain
Theblock height is not a unique identifier
