Share source area Vision network: "Blockchain is a shared distributed database technology. Its advantages are mainly prominently manifested in distributed decentralization, no need to trust systems, and cannot be tampered with and encrypted security. " . The meaning of blockchain technology Blockchain () technology is a decentralized consensus mechanism to maintain a complete, distributed, non -tampering ledger database technology, It allows participants in the blockchain to achieve a unified ledger system without building a trust relationship. The block is a public account, which is maintained by multi -point maintenance; the chain is to cover the timestamp (), which cannot be forged. Blockchain is essentially a technology that focuses on security and credibility. At present, there is a database behind all systems, which is a big ledger. Then whoever remembers this book becomes important. Who is the system now and who will account for the book. The accounts of each bank are all banks. Alipay's ledger is Ali. But now in the blockchain system, everyone in the system can have the opportunity to participate in the bookkeeping. If there is a new transaction data change in a certain period of time, everyone in the system can come to the bookkeeping. The system will judge the fastest and best person in this period of time. Send the contents of the ledger during this period to all the others in the system to back up. Everyone in this system has a complete ledger. Therefore, these data will become very safe. Tampereders need to modify more than half of the system node data at the same time to truly tampered with data. The cost of this tampering is extremely high, making it almost impossible. For example, Bitcoin has been operating for more than 7 years, and countless hackers around the world have tried to attack Bitcoin, but no transaction errors have so far. It can be considered that the Bitcoin blockchain has proven to be a safe and reliable system. Therefore, it can be considered that blockchain technology is a way for the whole people to participate in accounting, and it will bring the innovation of the bookkeeping method. . The technical advantages of the blockchain 1, distributed decentralization I due to each node and miner in the blockchain must follow the same accounting trading rules, and this rule is based on the based on The password algorithm is not credit. At the same time, each transaction requires the approval of other users in the network, so the decentralized trading system does not require a set of third -party intermediary structures or trust organizations. At present, whether it is a traditional trading system or a third -party trading system, it is based on the central account book system. The endorsement of the agency is a centralized trading network. 2, no need to trust the system In the blockchain network, through the self -restraint of the algorithm, any behavior of any malicious deception system will be excluded and suppressed by other nodes. Organization and credit endorsement. The traditional credit endorsement network system, participants need to trust enough for central institutions, and as the number of participating networks increases, the security of the system decreases. In contrast to the traditional situation, participants do not need to trust anyone in the blockchain network, but as participating nodes increase, the security of the system increases, and the data content can be fully disclosed. 3, cannot be tampered with and encrypted security In blockchain adopt one -way hash algorithm, and each newly generated block is strictly promoted in the sequence of timing lines. The behavior of data information in the blockchain is easily traced, resulting in the exclusion of other nodes, which can limit relevant illegal behaviors.
Blockchain technology has brought many benefits to all walks of life and provided security. Of course, blockchain technology has advantages and disadvantages. For example, compared with centralized databases, its operating efficiency is not high, and the storage space it needs is relatively large. What are the disadvantages?
. Advantages
1, distributed
Blockchain database is distributed storage, each node can be copied and stored a database A copy, if a certain node fails, will not affect the entire database technology. For example, in the BTC and EOS network, if there is a problem with a node, other nodes can still be made normally. There are more nodes in BTC in the world. This distributed storage can provide greater security to Bitcoin.
For the EOS network, although there are only 21 nodes, if one of the nodes fail, even being seized and attacked by some departments, other nodes can be topped immediately, and other nodes can be topped immediately. The stability and continuity of the node are not affected, and the overall network has not been affected.
In contrast, many traditional databases that depend on one or more servers are more likely to be attacked.
2, cannot be tampered with
The transactions that have been confirmed on the blockchain cannot be modified and deleted. Therefore Sensitive financial information, etc. Putting on the blockchain can prevent some personnel from fake fraud.
In the centralized database, administrators with some permissions can enter the database background to modify, and even delete certain records. This often provides some people with the possibility of cheating.
3, the relief system
We when we usually shop on Taobao, when paying, there is an intermediate payment dealer, which is Alipay. The money was given to Alipay. When the seller was shipped, and after receiving the goods, we had a click to confirm the receipt, and Alipay transferred the money to the seller. During the entire transaction, Alipay existed as a middleman for buyers and sellers.
Advantages of blockchain technology: 1. Remove the intermediate mechanism and reduce operating costs I due to the existence of no centralized intermediate mechanism, all information must be automatically run by pre -set rules and procedures. This rule is based on computer password algorithms, which naturally can successfully avoid the increase in operating costs increased by the credit endorsement of traditional intermediate institutions. 2, open and transparent, improve efficiency Because everyone has the same set of ledger, we don't have to worry about the errors caused by personal moral risks. Because this set of procedures will automatically isolate and reject these errors, at the same time, there is no need to organize a special person to verify the information, which greatly improves social operational efficiency. 3, more secure data In a traditional centralized network, an effective attack on any node of the center can cause the entire system to be paralyzed. The blockchain does not have a center. Each node is only part of the system. It has the same ledger and enjoy equal rights. Even if a node is broken, it will not affect the entire system. The king of digital currency Bitcoin, Bitcoin: Bitcoin has been running for more than seven years, and has suffered tens of millions of hackers, but no hacker can succeed in the Bitcoin operation system. Trading Bitcoin's website platform. Then you put the dug bitcoin at home. If you are stolen by hackers because of the strict custody, this is actually not related to the blockchain. In terms of data security, the design principle of the blockchain also has such a mechanism: the longer the running time, the more difficult it is to tamper. It can be said that the blockchain is getting time in exchange for people's increasing trust in it. The advantages will naturally have disadvantages. Where is the disadvantage of the blockchain? 1. Performance problems need to be broken From the current situation, the performance problems of the blockchain are mainly reflected in the throughput of throughput. Contradiction with storage bandwidth. In Bitcoin as an example, in the public chain, the processing capacity of 7 pens per second cannot meet the payment needs of the entire society; at the same time, all the transaction data of Bitcoin is close to 80G. For ordinary computers storage This is a big burden. If it is just to simply increase the size of the block to increase throughput, the Bitcoin will soon become a system that only a few large companies can run, and it violates the original intention of decentralized design. In Bitcoin, Ethereum and other public chain systems, the above -mentioned contradictions are the biggest challenges facing system design. 2. Privacy protection needs to be strengthened The traditional data is stored on the central server, and the system operator protects data privacy. However, in the public chain, there is no centralized operator, and every participant can get complete data backup, which also means that the database of the public chain is transparent. 3. The upgrade and repair mechanism needs to be explored. n is different from the upgrade method of the centralized system. In the public chain, because the number of nodes is huge, the identity of the participants is anonymous, and it is impossible to turn off the system for upgrading. In addition, because the public chain cannot be "shut down", the error repair is also extremely tricky. Once a problem occurs, especially the security loopholes, it will be very fatal.
