The calculation force of the miner returns to zero
garzik, was fortunate to be the owner of the first commercial ASIC miner.
the most difficult mining problem was 0, and the computing power was about 2p at the beginning of 2013, and now it has reached 100p
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

1. Unit voltage calibration: by adjusting the "system reference voltage" (about 3.0 by default), slowly increase and decrease the amplitude of 0.001, the unit voltage value can be changed until it is accurate! 2. Total voltage calibration: by adjusting the "total voltage ad value into the actual voltage of the parameters" (default about 3330), slowly adjust the size of this value, you can change the total voltage until accurate! 3. Current calibration: by adjusting the "current sensor range", slowly adjust the value, you can change the current until it is accurate
note: please do not change the item of "power starting current" in parameter setting, too large may lead to MOS tube burning and discharging!!!
