Celestia 掀起 “模块化” 热潮：Polkadot 是模块化区块链吗？

The launch of the author has aroused a lot of attention in the industry and also led to the upsurge of modular blockchain. Recently, blockchain has also announced that it will launch a data availability layer to enter the field of modular blockchain. So what is the modular blockchain that has recently emerged? What is the difference between the two? What is the modular blockchain? The modular blockchain we are discussing here refers to the modular blockchain in the ecological context of Isoethereum, and the concept corresponding to the modular blockchain is a single blockchain blockchain. The core responsibilities are generally divided into four parts: execution, supporting the execution of transactions, and realizing the deployment and interaction with smart contracts, ensuring the availability of data, and agreeing on the availability of transaction data. The content and sequence of transactions are allowed to be settled for completing transaction settlement, dispute verification and certification, and bridging between different execution layers. These responsibilities are all completed by one chain. For example, Bitcoin Ethereum is the representative of single blockchain, but this brings a problem that the scalability is poor and the cost is high. The transaction flow on the monomer chain comes from the concept of modular blockchain, and its core idea is to separate different responsibilities and outsource them to special independent layer modules, so that the scalability of the main chain is higher and the cost is lower. The comparative sources between monomer blockchain and modular blockchain are, for example, outsourcing the execution layer and so on, while outsourcing the data availability layer. In addition to external solutions, Ethereum itself is actually seeking to improve its scalability through technology. In the context of Taifang Ecology, modular blockchain is a technical scheme born to improve the scalability of Ethereum. It separates the implementation layer and data availability layer of blockchain into different modules. Is it a modular blockchain? We often hear the concept of modular blockchain in our school, but this is not the same as the modularization mentioned above. It is a heterogeneous multi-chain system, which is composed of a relay chain and a number of heterogeneous parallel chains. The relay chain is responsible for maintaining the consensus and security of the whole network, while the parallel chain can. Focusing on their respective applications and performance, parallel chains can achieve horizontal scalability by realizing cross-chain data transmission and interoperation architecture sources, that is, with the increase of parallel chains, the throughput of the network will also increase, and the asynchronous support technology being developed can further improve the scalability, so that the parallel chain block time of Boca can reach seconds, and it can support thousands of parallel chains, that is to say, the architecture of Boca cartoon with too many chains or fragmentation has largely solved the bottle of scalability. This is also the reason why we rarely discuss the scheme of improving scalability such as layers in the ecology, but Boca is indeed the pioneer of modular blockchain. Boca's architecture is modular. From the above description, it is not difficult to see that Boca's architecture itself embodies modular ideas. The relay chain is responsible for security and consensus. Each parallel chain can focus on building what it is good at, such as parallel chains focusing on identity. Focusing on each parallel chain is actually parallel in a modular ecology. Chains can interact with other parallel chains by sending cross-chain messages to use the functions provided by other parallel chain modules. Boca is still planning to minimize the relay, stripping some functions of the relay chain into multiple system parallel chains, thus reducing the burden on the relay chain and enabling the relay chain to better focus on consensus and security. At present, Boca has put the collective functions of the asset chain into the system parallel chain, and will also put the functions such as governance pledge transfer into the system parallel chain in the future. Parallel chain is a module in a blockchain. Minimizing relay is to improve the scalability of Boca blockchain through modularization. The framework of modular blockchain development framework is a modular open source framework for developing blockchain. It provides highly flexible and customizable modules for developers to design the modules in the operational logic of blockchain according to their own needs. They are called some predefined functional modules, so just like a blockchain Lego, developers can make use of existing ones. Modules quickly build a blockchain that meets their own needs, which greatly reduces the development threshold of blockchain. Developers can also develop their own convenience. Other chains can be quickly integrated. The following figure lists some module source documents contained in the framework, and more provide various rich functions, and the number is increasing. You can view the latest one here. It has recently been merged with the code base to form a blockchain software development kit for developing networks, which can be easily created by developers. In theory, it is also possible to decouple the data availability as a layer and provide it separately to expand the larger market, but this requires the community and developers to discuss and decide together. In Boca Forum, some community members have had a heated discussion about this. In addition, we can take advantage of the modular development to develop a data availability blockchain, which has actually been done by people. Blockchain project is developed by using the same framework, and the same consensus is used to summarize that modular blockchain is a technical scheme to separate different responsibilities of blockchain and hand them over to special independent modules. It is an important direction of blockchain technology evolution. In the ecology of Ethereum, modular blockchain is mainly put forward to solve the scalability problem of Ethereum. For example, in the ecology, modular blockchain is the essential feature of Boca. The architecture and modular development framework realize the innovation and customization of blockchain. 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
