The expansion of blockchain has become an important driving force for the development of the industry, and it is imperative to improve the throughput

        "The blockchain is very effective in decentralizing and ensuring security, but its TPS (system throughput) is very limited and can only handle very small transaction volume. This is one of the biggest challenges facing the blockchain at present." Vitalikbuterin, founder of Ethereum, said at the Wanxiang blockchain global summit on October 26. The expansion of blockchain is one of the hottest topics in the development of blockchain. In the early stage of the development of the blockchain, because the transaction volume is still relatively small, the use of transactions on the blockchain has increased rapidly in the past two years, and the development of enterprise application scenarios such as defi and gamefi means that the blockchain must be expanded to continue to operate.
        Gavinwood, the founder of Polkadot, also said: "there are many driving forces in the industry, one of which is scalability. That is, people constantly want to achieve higher TPS throughput.". "There is a simple way to expand the capacity of the blockchain, but there is also a difficult way. The simple way is to adjust the block size and gas upper limit, and increase these parameters, so that we can handle a large increase in transaction volume. The difficult way is layer2 technology." Vitalikbuterin. However, although the method of increasing the block size and gas ceiling can handle larger transaction volume, it will sacrifice decentralization.
        By creating a huge system, each single node needs to process a large amount of data. Such a system is likely to lose its centralization, because such a large node is difficult to operate. Another way is the development of layer2 technology. However, due to the complexity of its technology, there are some lightning networks and state channels. At present, rollup technology is the most common technology that can truly realize the native implementation of the split expansion technology of Ethereum, and it has promoted the substantial reduction of transaction costs. Starting in 2014, it will gradually take shape in 2019. So far, it can be increased by at least 100 times. For many domains, it is important to migrate to rollup.
        Vitalikbuterin introduced that for non-financial applications, the cost can be reduced as much as possible; In addition, interactive business models such as games also need rollup very much. For example, the dark forest game based on Ethereum is a completely credit free interactive model. It continues to run on the test network and can be migrated to rollup in the future. NFT can also be migrated to rollup. In addition, infrastructure and financial services, such as applications that pay with cryptocurrency and Dao, can also be migrated to rollup. "The path of building infrastructure and realizing the expansion of Ethereum does not only exist in theory, but we have a clear road map.
        Moreover, many components of this roadmap have been implemented, or have entered the deployment stage of the main network, or are in full swing development. " Vitalikbuterin. Vitalikbuterin pointed out that "layer2 is the future of Ethereum expansion. Using layer2 to achieve Ethereum expansion is the only security method at present, while preserving the core of the blockchain - decentralization". Gavinwood emphasized that there is no shortcut for decentralization and security. We should pay attention to decentralization, and we also need to focus on security, and scalability is the most important element in all this.
        In this regard, in order to achieve the goals of decentralization, security and scalability, the four major differences between the substrate parallel chain platform built by gavinwood team and other platforms are line P, scalable, unlimited logic flexibility and economic flexibility. With the rapid development of the industry, the Ethereum centralized RPC server will soon disappear in the future; For example, hosting wallets and decentralized application websites, if there is a centralized network server behind them, they will also face regulatory difficulties. In addition, custody services, multi sign wallets and non P2P stable coins may be regulated in the future. Under this trend, many projects will no longer exist.
