Deep Sea chain DSC Digital currency link
Public chain, also known as "public chain", refers to the blockchain that anyone in the world can enter the system at any time to read data, send confirmatory transactions and compete for bookkeeping. The public chain is generally considered to be "completely decentralized", because no indivial or institution can control or tamper with the reading and writing of data in it. In terms of application, blockchain public chain mainly includes bitcoin, Ethereum, super ledger, most counterfeit currencies and smart contracts. The ancestor of blockchain public chain is bitcoin blockchain, which has the following characteristics:
1, open source code
upload the code to GitHub, and everyone can get complete blockchain data by downloading, Accept the test of the public
2, complete decentralization
anyone can become a node, each node is open, everyone can participate in the calculation of the blockchain, any node is not permanent, but phased, and any center is not mandatory for nodes. Anyone can read and send transactions, and transactions can be effectively confirmed on the blockchain. Anyone can participate in the consensus process. The consensus process determines whether a block can be added to the blockchain and the exact current state. Everyone can get financial reward from it, which is proportional to their contribution to the consensus process. These public chains are generally considered to be "completely decentralized"
3. Developing decentralized applications
through this public chain, developers can easily develop centralized applications. Public chain can protect the rights and interests of users from the influence of program developers
blockchain technology is not only the underlying technology of bitcoin, but also the core and infrastructure of bitcoin bitcoin has been running without any centralized organization operation and management. Later, bitcoin technology was abstracted, which was called blockchain technology or distributed ledger technology
extended data:
disadvantages of blockchain technology applied to digital currency:
first, there is no circulation management organization for "decentralization" blockchain technology is essentially a distributed database system with one-way linked list logic structure and P2P network design mode, which determines that there is no unified central control system for virtual currency based on blockchain technology
Second, it is difficult to effectively control the quantity supply the circulation of virtual currency based on blockchain technology is fixed, and according to Fisher Equation, the total transaction volume of the whole society under a certain price level in a certain period has a certain proportion with the required nominal currency volume, while the constant currency volume obviously can not meet the requirements of the growing total price of social goods Thirdly, "mining mechanism" is difficult to create recognized value bitcoin itself has no value and no national credit support. Some people think that "by continuously consuming computing power and energy to inject value into virtual currency", but it is obviously not the most efficient choice to consume millions of calculations in order to find a hash value that meets the requirements Fourthly, procers and early holders are easy to get high seigniorage any virtual currency based on blockchain technology is held by a few people at the initial stage of its development. Take bitcoin as an example. At first, bitcoin was only a proct of a few people's game. The first bitcoin purchase in May 2010 was $10000 BTC's purchase of $25 pizza. The first bitcoin transaction completed in July of the same year was $0.04/btc1; Pithy formula test business&# 8194;
divisor is the division of the whole ten. Generally speaking, you can use the formula to test the quotient directly
Second, "round off" method&# 8194;
"rounding" method is the most common method and the most widely used method, which can be said to be the general method of trial quotient
Third, half estimate 5&# 8194;
when the first two digits of the divisor are equal to or close to half of the divisor, the initial quotient can be set as 5
four, the same head is not enough business 8, 9&# 8194;
when the first two digits of the divisor are the same as the number on the highest digit of the divisor's two digits, it is the same header< 5. Try in high position and adjust in low position&# 8194;
divisor is a two digit number, and the first two digits of the divisor are considered< 6. Test quotient of divisor 25
master the multiple of 25, so you can get the quotient quickly.
1. Replace the driver of the graphics card. It is recommended to download the latest version for installation on the official website of the graphics card brand. If the driver does not match the game program or the driver has been damaged, the frequency rection will also occur
2. Check the temperature of the graphics card. If the graphics card has been used for more than one year, you need to clean the st of the graphics card fan and PCB board. If it is convenient, it is best to coat the core of the GPU with appropriate silicone grease.
others are overclocking
I don't know what type of graphics card you are. It's hard to say
n card. Go to the next overclocking software. Others pull up, you pull back~
if it's a card. No, I don't know
it is more complicated to modify the graphics card BIOS file, but it is not recommended.
