jewelry wholesale sumter south carolina We say that the blockchain is currently immature and has various problems, such as slow processing speed, high handling fees, hidden safety hazards, etc. These are the most intuitive experiences of users. The experience is not very good. There is also a problem with the blockchain, which is the problem.
What is the problem of high concurrency, let's talk briefly. High -combined hair is a problem in the field of computer. Simply put, the problem of high concurrency is that the system cannot run multiple tasks at the same time.
Many tasks run at the same time. A lot of users pour in. The system cannot bear so many tasks. There will be high concurrency problems. Your system will be stuck. It is like the Spring Festival. Living may be caused by high and issue problems.
The traditional Internet and high concurrency problems, and the blockchain network naturally also has this problem. After all, the maturity of the blockchain is still a big gap compared to the traditional Internet. However, if there is no safe, reliable and efficient public chain, the development of the entire blockchain industry will be severely restricted, and the application of landing is also empty talk.
In this context, DAG technology is proposed. The full name of DAG is "Directed Acyclic Graph", which is translated in Chinese as "there is no loop."
DAG What is the same as the ring picture? What can it play? Let's explain below.
1. DAG: A new type of data structure
DAG, the Chinese name is "There is no loop". From the literal meaning, "there is direction" that means it has direction,
"No loop" means that it has no circuit and cannot form a closed loop. Therefore, DAG is actually a new type of data structure. This data structure has a direction and at the same time cannot form a closed loop.
The traditional block, we always use "block" as a unit, and one block often contains multiple transaction information. In DAG, there is no concept of block, but in the "unit" as the unit. Each unit records the transaction of a single user. The unit formed is not a block, but a transaction. It can save time for packing.
It simply speaking, the biggest difference between the blockchain and DAG is: The blockchain is a blockchain one by one to store and verify the distributed ledger of the transaction, and the DAG is each stroke. The transaction is regarded as a block, and each transaction can be linked to multiple previous transactions to verify.
. The working principle of DAG
The on the traditional blockchain, as far as Bitcoin is concerned, it is a single -chain structure. Come (Figure 1), the data is recorded on a main chain. In the case of inappropriate metaphors, this
"single -chain" structure is a chain arranged.
The blockchain has only one single -chain, and it cannot be executed concurrently when it is packaged. The new block will be added to the original longest chain, and all nodes will be based on the longest chain, and continue to spread infinitely according to the order of the timestamp. For DAG, each newly added unit not only adds one unit of the longest chain, but also to all the previous units (see Figure 2).
For example: Assuming I posted a new transaction, at this time the DAG structure already has two effective trading units, then my trading unit will actively link to the two of the previous two to verify and verify and verify and verify and verify and verify and check It is confirmed that until the link to the creation unit, and the hash of the previous unit will include it in its own unit.
In other words, if you want to deal with a transaction, you must verify the previous transactions, verify several transactions, and conduct according to different rules. This verification method allows DAG to write many transactions asynchronously, and ultimately constitutes a tree -like structure of topology, which greatly improves scalability.
The is a ringless diagram based on DAG, and each transaction directly participates in maintaining the entire network. When the transaction was initiated, the entire network was broadcast, and the miner packaged the block stage, which saved the time of the packing transaction out of the package, which improved the efficiency of the blockchain processing transaction.
Over time, the blockchain of all transactions is connected to each other to form a structure structure. If the data is to be changed, it is not just a few blocks. Essence Compared with the DAG model, the complexity to be carried out is higher and it is more difficult to change.
Summary, DAG, as a new type of decentralized data structure, belongs to a broad blockchain, has the attributes of decentralization, but the difference between the two is:
areas in the area area The blockchain composition unit is block (block), and the DAG composition unit is TX (transaction).
Blockchain is a single thread, and DAG is multi -threaded.
All transaction records of the blockchain are recorded in the same block, and each transaction of DAG is recorded separately in each transaction.
Blockchain requires miners, DAG does not need miners.
. The representative of DAG: IOTA
DAG's current representative project, the most well -known is undoubtedly IoTA. It can be said that it is precisely because the currency of IoTA rushed into the fourth place in the market value in the second half of 2017 that people really realized its underlying technology: DAG has a ringless chart.
iota proposes the concept of "tangling" on the basis of DAG to a ringless graph. In IoTA, there is no concept of block. The smallest unit of consensus is transaction. Each transaction will quote the two trading records of the past, so that the previous transaction will prove the legitimacy of the two transactions in the past, indirectly prove the legitimacy of all previous transactions. In this way, a small number of nodes such as miners in traditional blockchains are no longer needed to verify transactions and packaging blocks, thereby improving efficiency and saving transaction costs.
. The current situation of DAG
Theoretically, DAG has some disadvantages that can make up for traditional blockchain, but it is currently not mature. , And younger.
This does not take 10 years like Bitcoin to verify the security of the entire system, nor does it achieve a wide range of application scenarios like Ethereum. However, some voices are now proposed to use the data structure of "traditional blockchain DAG", but there are no very prominent cases, so I won't say much here.
The summary, this section we introduce the derivative technology of the blockchain: DAG has a ringless diagram, which is a new data structure that can achieve the efficiency of the transaction of the blockchain and achieve significant efforts to achieve significant efficiency and achieve significant efforts to achieve significant efforts to achieve significant efficiency and achieve significant efforts to achieve significant efforts to achieve significant efficiency and achieve significant efforts to achieve significant power. Improvement.

wholesale fine jewelry supplies The directional diagram is based on the analysis of the correlation coefficient and partial relationship between the disturbance items, and identify the causal relationship between the same period between the variables. Can be implemented with Tetrad software. As for economic evidence, just search for a paper to see it.
