One of the most concerned things in cryptocurrency industry in 2022 is merger. Although most Web3 enthusiasts regard it as an investment opportunity, and get rapid benefits due to ETH price speculation, many people don't know how to prove their rights and interests. How should the transfer of (PoS) Ethereum develop?

What is a merger?

According to the original design scheme, the workload proof (PoW) of the Ethereum blockchain requires the verifier (also known as mining) to carry out complex cryptographic problems to authenticate the sale and establish a new blockchain. This process requires a lot of calculation level, and it has been criticized by many people for its impact on the environment. On the other hand, in order to obtain the authentication transaction and establish the control right of the new town block, the consensus mechanism is a system software, and the verifier must put its data coins into it. These systems are expected to reduce the carbon emissions of Ethereum by about 99.95%. Simply put, Merge refers to the connection of Ethereum from the consensus blockchain technology of PoW to the consensus blockchain of PoS. Today, Ethereum also has parallel processing PoW and PoS chains. Although both transmission chains have verifiers, now only PoW transmission chains can handle customers' sales. After the merger, Ethereum will be transferred to the PoS chain, which is called the portal chain, thus making PoW excavation obsolete. Although there are some wrong reports about the Merge and how to reduce the cost of motor gasoline, the problem of accountability is not as critical as TimBeiko, a researcher at the Ethereum Foundation. In turn, the merger addresses the following challenges. This test is called the obstacle to the popularity of cryptocurrency: the speed of buying and selling is slow; High pollution causes an increase in carbon emissions; The threshold of participation is higher, because it becomes the network resource needed by mining or verifier.

How to change the merged Ethereum as we know it now?

The merger is committed to the minimum harm to the operation mode of Ethereum from the perspectives of end users, smart contracts and dapp. However, there are some small changes to pay special attention to.

1. Small block structure

After the merger, we will see the introduction of new blocks, which will include the specific content of PoW blocks at this stage as one of the components, in a component called ExecutionPayloads. We will also see some PoW head damage that will no longer be related to the new PoS chain. The value of this keyword should be set as the zero equivalent value of its future algorithm design, rather than being completely deleted, so as to minimize the damage to the current infrastructure of the tool.

2. Reliability and reducing the time of block removal.

It is estimated that the merger will reduce the average time required to establish a new block in the long-term stable Ethereum, which is only 12 seconds. At present, it takes about 13 seconds to create a new block under PoW, which means that sometimes it may take a long time, and sometimes it may not take 13 seconds. Although this head represents a change of 1 second, now smart contracts can better understand the expected block time for calculation.

3.Finalized and Safehead blocks

At this stage, in order to regard one block in the Ethereum as "confirmed", other blocks must be excavated on the wall. With the introduction of the last block theory, it is predicted that the merger will change. The last block is only accepted by more than two-thirds of the verifiers. This means that cyber attacks must create a contradictory block and at least destroy the total equity. . In the normal Internet environment, Merge will continue to introduce a secure header block. Assuming that the network delay is less than 4 seconds, this block is expected to be included in the transmission chain.

How to prepare Truffle for Merge in advance?

In Truffle, I am very excited about the merger! Here are some ways to lay the foundation for this. Everyone is updating the Truffle box that used to throw away the test network, and adding strong support for the new test network. Truffleboxes is a valuable template code that allows dapp developers to focus on the unique logic of their applications. At this stage, some small boxes include some test network configuration options, which are discarded after merging, such as Rinkeby and Ropsten test networks. Everyone is updating this architecture to eliminate the lost test network and add a pair of leboxebon. , solve Parity, etc.).

Summary

In Truffle, we are still committed to assisting a new dapp development staff to add jobs by establishing a means for developers and educating raw materials through network resources, so as to improve and simplify the customer experience of dapp development staff in the Web3 ecosystem. With this update, I arrived at Ethereum, and I was more excited and committed to this course.
