How did the block come about?

Now, countless transactions occur all over the world. In what order should they enter the chain? Naturally, TX, which is fast in time, should be included in the chain first. Let's think about the banking system. What would the world be like if banks handled transactions in the order of payment of fees rather than in the order of time when the transactions occurred? It'll be a mess. Of course, there may be computer problems or other exceptional situations. However, not in this exceptional case, everyone would agree that the world's economy would be messed up if the transaction order was generally set on a commission basis.

If the existing blockchain is only for gambling, DeFi, money laundering, P2E, and tax evasion, it is okay to set TX's chain entry ranking based on fees. However, in the operation of the blockchain, for example, if you want Ethereum to be used in general retail transactions, that is, in order for Ethereum to have a status of card, the atmosphere will now change. In principle, TXs should be accepted in chronological order.

So, you just put TXs in the chain in the order in which they occurred, and in this case, creating the block is essentially unnecessary. For the purpose of the blockchain to support the economic order by recording transactions, only a chain of TXs needs to exist, and there is no reason to collect a bunch of these TXs, pack them in blocks, and enter the chain. But why couldn't Satoshi not use the block concept?

It was because of the decentralization. It was to decentralize those who decide the order, whether in chronological or commission order. He wanted an unspecified random node in equal qualifications, not one centralized node, to sequencing the TXs. In this way, even if some of the P2P nodes fail, the entire node can roll resolutely. And can be free from centralized power.

At this moment, however, Satoshi ran into a barrier. It doesn't matter if it's in chronological order or commission order in this scene. Furthermore, even which node will perform this task is not important in this scene. The only problem in this scene was, at a particular moment, how to identify the TX that was created first or provided the highest commission.

This is impossible. It is impossible not only practically but also theoretically. This is because it is impossible for a node to check the birth time or fee of TXs existing in a mempool around the world at a certain point unless it is based on infinite speed. Eventually, the concept of a certain period of time became necessary, and this very certain period became the origin of the concept of block.

The nodes wait for a certain period of time and brings together TXs from all over the world. And they sort the TXs in chronological order or commission order and insert them into the block. And include the block in the chain. Blockchain was born this way. The reason why Bitcoin has a block time of about 10 minutes and Ethereum 10 seconds is as above.

Consider a structure in which any one centralized node A receives TXs. In this case, it is enough to send TX only to A unconditionally from nodes all over the world. For example, it's like we do a keyword search on Google. Google accepts and processes requests in the order of keyword entry, that is, chronologically. There is no need to wait 10 seconds for keywords and then collect and process them. It just has to process the keywords in the order they come in. Therefore, in this case, the concept of block time is not necessary, and the block also becomes an unnecessary concept. Therefore, if this structure is adopted in the blockchain, the concept of the blockchain disappears and only the concept of TX chain or hashing chain remains. The efficiency increases by leaps and bounds. However, there is a centralized power called Google. All P2P nodes take the shape of a tree. This is typical of centralization. Satoshi hated seeing this.

But Satoshi was too hasty. His decentralization was too excessive. The effect of centralization can be achieved without any centralized power. Decentralization is not a religion. It is a concept of means for some purpose or utility. But now decentralization has become a religion called the emperor's new clothes and people are praising the invisible clothes of the emperor.

There are countless ways to centralize any one of the entire P2P nodes. One of them is to implement a six-month term system. It is also possible to introduce a voting system. There are really many ways. However, Satoshi did not seem to have enough power to think about them at the time. This kind of thing is always the case when programming. When creating something for the first time in the world, energy shortages are bound to occur. So Satoshi seems to have no time to think about "centralization without centralized power." In fact, the biggest mistake is that he created his own database system independently without introducing a versatile database. My guess is that he has exhausted a great deal of energy in database works. Even Ethereum inherited this mistake. If Satoshi or Buterin were familiar with a versatile database, they would of course have introduced MYSQL.

The idea that decentralization will bring heaven to the financial system is nothing but fantasy. Rather, it is the current situation that only tax evasion, money laundering, and gambling are thriving. In particular, in order for blockchain to be used as a general payment method in the future, two things must be removed. One is block time, and the other is a commission-based TXs inclusion method. That is, all TXs must be processed in chronological order and processed immediately upon occurrence.

This is possible. Democratic centralization without centralized power is possible. This is the most efficient blockchain structure and it can be said to be the appearance of decentralization in a true sense. Eventually, the concept of block disappears in the blockchain, and only the concept of TX remains. Blockchain will be renamed TX chain. And this new structure has one incredibly important side effect. It is that the fork phenomenon will disappear completely.

Satoshi's dream was to use Bitcoin as a payment method for general transactions. But it was an impossible idea in the first place. As a "block" chain, that dream cannot be achieved. It is only possible with the "TX" chain.
