As the saying goes, elephants never forget. The same is true of blockchains.
Memory is the core of block chain. it is a breakthrough computer programming language built in a key way, which is very similar to the human mind. Just as our memories are linked by association, for example, the smell of chicken soup may arouse concern for children, and the smell of perfume may remind people of the love they once had. The same is true for each code "block" in the transaction "chain", which is inextricably linked to the previous block.
Like the proverbial elephant, blockchain memory is absolutely reliable. Because each new block contains a hash or line of code for the previous block, and each block must be validated before it is added, the block chain cannot be changed. For example, after remitting money to someone in a transaction, the transaction may be cancelled because of a subsequent entry (receiving a refund), but even the person who initiated the transaction cannot tamper with the transaction.
The more transactions in the blockchain, the more memory is used. The crypto currency "miner" validates the new transaction, searches for the unique hash assigned to them, and then encrypts and compresses each entry to ensure the security and reliability of the block chain. These efforts are crucial in the absence of middlemen such as financial institutions to monitor the books. To get the job done, the miner needs plenty of computer memory and extremely fast processing speed.
With the increase in blockchain length and complexity, if memory, storage, and processing power does not continue to grow in a virtual world where everything will not be forgotten, how can technology realize incredible potential?
This is an important issue because the era of blockchain has arrived. Soon, it could be the basis for all our digital transactions, including some that we have not yet imagined. Developers are already writing applications based on blockchain. Enterprises are using blockchain technology. Consumers who buy and sell encrypted currencies such as bitcoin are also using blockchain technology, and there will soon be more uses.
As long as we have the infrastructure to support blockchain, blockchain is bound to change what we can do with computing devices in business and in our daily lives. Adequate computer memory will be the key, especially the device or "node" used to validate the transaction. Even if we, as human beings, forget the transactions entrusted to the books, we can rest easy, because the blockchain will not be forgotten.
Working principle of Block chain.
The types of tasks we perform on digital devices can be divided into two categories: tradable and non-tradable. Writing emails, watching videos and browsing the Internet are largely non-trading, which means we don't buy or sell anything or sign any contractual agreements. However, we are increasingly doing transactions online, such as signing contracts, booking and buying items.
The Internet is already processing these transactions faster than in the pre-digital "analog" era. Not long ago, we had to go shopping in stores or by telephone and pay by cash, credit cards or cheques. Do you remember the check? In order to sign the contract, we had to wait for the paper document to arrive by mail, then sign it and send it back by mail.
Digital transactions are faster and more convenient, but they may not be secure, and cybercriminals may access our accounts, or access our social security numbers and other sensitive information. Most transactions today still need to be handled through third parties, such as banks, credit card companies, lawyers or real estate companies. However, these problems do not exist in blockchain.
Blockchain is designed as a virtual public account book that can be viewed by all and written in a way that cannot be erased. Each block is a file that creates a new file every 10 minutes that contains records of all previous transactions listed in order and ends when there are new transactions. In digital terms, a blockchain is a distributed database, which means it will not be created, extended, or stored on a CPU. Instead, each computer or "node" used to process and validate transactions has a copy. After you add a deal, all copies change at the same time.
Just as a mock book usually includes the date of each entry and possibly even the time, each block in the blockchain has a timestamp so that everyone can see when it was added. It also has an encrypted signature called Hash, which compresses the block and encrypts it. Users can access their transactions using a private code or a "key", which is very confidential, even if the system that issued the key does not have a copy. If someone accidentally loses their key, they cannot decrypt their entries and cannot access anything stored or recorded in it. The misplaced private key has cost thousands of dollars in encrypted currency and will never be recovered unless the key is found.
A brief History of Block chain.
Bitcoin, the virtual currency, is the most famous use of blockchain. This is also the reason for the existence of this technology. Bitcoin was proposed in 2008, and a white paper describes a "pure P2P e-cash" written by a mysterious person who uses the pseudonym Satoshi Nakamoto, whose identity is still unknown. For years, the world's first cryptocurrency hovered on the brink of public awareness until something very surprising happened.
In 2017, when the value of bitcoin soared from $1000 a unit at the beginning of the year to nearly $20000 (a 2000 per cent increase) in mid-December, Bitcoin was hyped and hyped, sparking limitless public imagination. The surge sparked a virtual "gold rush" between new and established institutional investors, with miners, managers of crypto currencies, snapping up the hardware needed to perform complex calculations, resulting in a shortage of hardware.
While the subsequent collapse in value calmed the bitcoin frenzy, interest in digital cash remained. Now that more than 700 "copycat" currencies are vying for market share, their investors want to recreate the popularity of bitcoin. The U.S. Treasury Department noted in its first quarter 2018 report that G20 financial institutions are "interested in encrypted assets." it has increased sharply over the past year. "
Memory is the only thing that can achieve the processing power of encrypted currency. A lot of memory.
Block chain mining.
Most people who use cryptocurrency or any other form of blockchain do not need a dedicated processor or additional memory. They only care about transactions they make using applications or websites.
However, the miner needs to access the entire blockchain to process and verify the transaction.
At the time of this writing, there are already 532698 blocks on the bitcoin chain, and a new block is added to the chain every 8 minutes and 19 seconds, with a price of nearly $7500 per bitcoin.
Before you can add a block, you must assign it unique code, or hash, to it. Finding the correct hash is a complex process using mathematical algorithms that can only be solved by a computer. Speed is crucial: after opening hundreds of deals and bundling them into a block, the miners scrambled to be the first to solve the problem. The winning computer will win a reward, which, at the time of writing, is a "nugget" of 12. 5 bitcoins per block, or about $94000, plus a fee for each transaction in the block.
Therefore, to get paid, you need to be equipped with ultra-high-speed computers and a lot of memory. To start a block, the software first creates a file that may take up 8 GB space. However, fast processing requires a lot of free memory. Therefore, in order to do the heavy work, the miners usually use the special processing chip (ASIC), which is specially designed for bitcoin mining, for most other currencies, it is to add memory to their computers. These dedicated ASIC require continuous provision of data in order to maximize problem-solving capabilities, which are currently provided by DDR4 DRAM.
Powered by memory.
When mining non-Bitcoin cryptocurrencies, including the most well-known counterfeit coin, etheric Square, it is best to use a video card (also known as a video card) that contains a graphics processing unit (GPU) chip. These graphics cards are typically used to improve computing power to support the graphical display of video games, but they are equally important for cryptocurrency mining.
At run time, each GPU requires an average of 7 GB graphics with double data transfer rate (GDDR) memory, which is a dedicated computing memory that processes much faster than traditional computing memory. Many miners use multiple GPU at a time. The current video card uses Meiguang's GDDR5 and GDDR5x video memory. The next generation of graphics cards will use Micron's latest GDDR6 technology and have now proven to be able to process up to 20 GB of data per second. GDDR6 is designed for many high-bandwidth, high-speed applications, including graphics, networking, and automotive applications. The miners are sure to benefit from the super-speed brought about by GDDR6.
"We are mainly building video memory technology for games and other traditional high-performance applications. "but this memory is also ideal for cryptocurrency mining," said Bryan Craven, Micron's strategic marketing manager. "
As the application and use of blockchain grows, so will the demand for computational memory and faster processing speed.
Since the early days of Bitcoin, Meguang has been at the forefront of the blockchain revolution and encrypted mining. Our GDDR memory is already popular with video game players, and they have been providing the memory bandwidth and speed needed to create blockchain technology. Micron GDDR6 and other memory technologies will ensure that blockchains can continue to record, manage, and protect our digital transactions-and perhaps most importantly, they will never forget.
Domain of use.
Cryptocurrency is the most well-known use of blockchain. But as a secure and fast P2P mechanism for transferring money and conducting a variety of financial and other transactions, the technology has aroused the imagination of developers and innovators. Uses include:
Smart contract. Gone are the long waiting times and cumbersome processes for banks, mortgage companies, insurance brokers and others to deal with paperwork. "Smart" contracts based on blockchain can be traded directly between the parties ("P2P") and can be executed on their own through the "if-then" (if-then) clause. For example: if I deposit the X amount into the Z account, then the ownership of the house will be mine.
Smart trading. Using blockchain to trade stocks is faster and cheaper. The use of decentralized transparent distributed books eliminates the need for intermediation, transaction licensing and supervision, and eliminates the tedious paperwork that slows down the process.
Smart energy. The combination of blockchain digital technology, power companies monitoring energy consumption through digital meters and the "smart" grid that provides electricity, off-grid solar energy and wind power generation, In this way, people and companies can "P2P" sell and provide electricity in direct transactions that bypass power companies.
Intelligent supply chain. With sensors and data provided by sensors, companies can see where goods and products are located, where they flow next, and where they are on the blockchain.
Intelligent health record. Blockchain accounts store, protect, and manage people's medical records, and only specific parties can use access keys. Through smart contracts, medical facilities can collect health records from insurance companies as soon as certain conditions are met, such as patients after surgery or on admission or discharge.
Smart passport. The developer community Github has launched a digital passport in 2014. Users can take photos and seal them with encrypted public and private keys to verify their legitimacy and provide access to the account book where the passport is stored.
Smart cross-border payments. Cross-border remittances can be slow, expensive and likely to go wrong because of the large number of banks and other intermediaries involved. Companies, including Abra, Align Commerce and Bitspark, have provided fast and cheap remittance services assisted by blockchain, and blockchain developer Ripple is working with banks to provide today's international remittance services.
Smart home appliances. The "Internet of things" connects our household appliances to the Internet as never before, making it easy for us to manage remotely. Blockchain technology can not only protect and help us safely transfer ownership of the equipment, but also implement the "if-then" structure, for example, when the milk stock is small, it triggers the refrigerator to automatically order milk and pay for milk.
