模块化区块链是什么？Astar 将怎样融入其中？

When it announced its ambition last year, modular blockchain became a widely discussed topic. Since then, modular theory has become popular rapidly, thanks to the booming ecosystem, countless data availability layers have been introduced one after another. However, the concept of modular blockchain is not brand-new and not only in research. This paper will introduce the differences between single blockchain and modular blockchain and how the network integrates into them. Most of them are so-called single chains. What is a single chain? Although consensus is the most controversial topic at startup, the discussion has been transferred to different layers. Blockchain has four core responsibilities. Consensus is reached on the validity of state transition in a decentralized node network. The actual transaction settlement submitted by users and smart contracts usually occurs at the same time as the execution in the modular chain. The settlement transaction is considered to be final because the possibility of chain rollback is small. One of the characteristics of data availability blockchain that is often praised is that Transparency data availability is the function to achieve this. It provides all the data needed to reconstruct the transaction history and verify the current state of the network. In a single chain like Bitcoin and Ethereum, the same group of verifiers handles all the above functions, which usually automatically limits the number of verifiers who can run, because with the use of the network, the computing requirements will increase the data stored by the Ethereum archive node, which is not the storage capacity that you will have on your mobile phone at all. Very high, especially in the competition for mining awards, in order not to exhaust hardware resources and thus reduce the degree of decentralization, the new expansion scheme is focusing on decomposing the task modular blockchain. Simply put, modular blockchain is a blockchain that is dedicated to one or two core functions of blockchain and leaves other functions to developers. This means that modular blockchain like or only focuses on data availability and puts other functions aside. The source blog background information is expanded and cheap. At first glance, we may not know the benefits of modularity, but if we understand the evolution history of the expansion of Ethereum, it is not difficult to understand that the initial expansion vision of Ethereum is fragmentation, which means dividing the whole network into different small blockchains. However, this will require major changes to the blockchain, which is why the road map has turned to the second layer of expansion and expansion to increase the throughput of the underlying chain by moving transactions out of the transaction and submitting the results of batch transactions. However, as active users may have noticed, it doesn't necessarily mean that they can keep the cost low. During the period of high traffic, the cost of the recently launched network soared to US dollars, which seems acceptable to enthusiasts, but it is not in the context of large-scale adoption. One reason for the soaring cost is that the price will naturally adjust during the period of high demand and the mechanism to prevent junk trading. However, the cost is usually also affected by these mechanisms in releasing data to Ethereum. As much as the cost-driven operating cost is composed of the cost of publishing transaction data to the main network, even if it is finally introduced and provided with additional storage for the data, the cost will still be quite high. Introducing modularity requires publishing its transaction data so that anyone can verify its status and ensure that its transaction is legal. However, they do not need to use the Ethernet main network to achieve data availability. On the contrary, operators can significantly reduce the cost by using solutions like or. Some solutions usually have greatly reduced storage costs, and the benefits of reducing data publishing costs will be passed on to users. In order to create a better overall experience, although data availability may be the most optimized part in all stacks at present, it is only a modular blockchain that is specially responsible for implementation. The overall idea of modular blockchain is that instead of imposing various core functions on the same group of machines, it is better to distribute tasks and optimize multiple layers to serve specific tasks. This also allows developers to create a multi-layer combination that is most suitable for their use cases, just like using Lego bricks. They can combine the cheapest and focused execution layer and the security of Ethereum provided by re-pledge. This method reduces the cost of developing the whole chain from scratch and provides a solution that relies on other network security instead of self-starting. In short, the benefits of modularization include reducing the cost and time of developing and launching new chains, providing flexibility that single chains cannot match, and Scalability, as mentioned before, although modularity is not entirely new, it has been a part of the ecosystem narrative of application chains like and since they came out. Both of them have built a modular framework, allowing chains to choose different modules and combine them to meet their needs. So how did the network start? At first, it was started as a parallel chain in the world. It created an intelligent contract center, and other parallel chains could use this ecosystem, so it was big. Economists may think that it is a single chain, but because it is a part of the ecology, the situation is somewhat different. It is essentially based on allowing parallel chains to inherit the security guarantee of the bottom chain, making it similar to the current modular chain. The relay chain is responsible for security and consensus, while the developers on the parallel chain can focus on their unique advantages. As one of the most successful parallel chains, they have supported the builders who are popular in the community by establishing a pledge mechanism. Recently, we have extended to the Ethereum ecosystem, and we are still making progress. In the past two years, we have gained the experience of using modular framework to build a modular chain. The future of blockchain is modular. Although there is still a place for the single chain that has achieved segmentation or found its own market segment, there are more and more signs that we will build it modularly in the future. Although everyone is very excited and looking forward to the idea of stacking different technical layers together like multi-layer cakes, there are still some needs for modular blockchain. The challenge to be solved in the modular paradigm, security depends to a great extent on the bottom developers, who will have to choose carefully to avoid the interruption of other layers due to the failure of one layer, which is just like forgetting to make the bottom of the biscuit of the black forest cake, so that the whole cake will collapse. In addition, although optimizing each layer can produce a better experience than the sum of the parts, it is challenging at the cost of increasing complexity to deal with fraud certificates or validity certificates to ensure that the calculations of other layers are correct, not to mention the modular blockchain has further introduced fragmentation in the fragmented ecological landscape. 比特币今日价格行情网_okx交易所app_永续合约_比特币怎么买卖交易_虚拟币交易所平台
