Blockchain has not yet developed killer applications.
So far, most of the application of blockchain technology is based on its utility: on the one hand, traditional institutions regard it as a “distributable, non-tamperable, and trust-solving problem” distributed ledger technology, using blockchain as a tool. To improve the quality of traditional industries; on the other hand, independent DAPP developers mostly use the most mature application of the blockchain – cryptocurrency, looking for scenarios that make it easy for cryptocurrency to flow, to attract traffic, such as gaming, games, etc. .
These two applications of blockchain have great limitations. Traditional institutions use the blockchain as a tool to solve existing problems, but in reality they limit the role of the blockchain to a known range and cannot stimulate real innovation. DAPPs such as gambling and games are more like the use of blockchains. The supported cryptocurrency is used as a traffic container to allow audiences from all regions who cannot interact because of payment, transaction and other technical barriers to enter a community through the blockchain.
Only from the utility of the blockchain , the innovation space of the blockchain is very limited, and the” killer application” will not happen. In order to exploit the potential of blockchain technology, it is necessary to start from the technology itself – instead of using blockchain technology to solve existing problems, blockchain technology is used to create new scenarios and models.
If you start from the blockchain technology itself and consider the possible DApp, you will soon encounter a problem: blockchain technology is not a pure technology, whether it is from the type of blockchain or the blockchain itself. Technologies such as encryption, distributed computing, distributed ledgers, etc., DPCs that can be supported by blockchains cannot be of only one type, or correspond to several specific industries; blockchain applications are based on the type of chain used and the technology used. Different emphasis can form a hierarchical menu.
The first level of large division is generated according to the type of blockchain: the consortium and the public chain, corresponding to whether the blockchain utility is generated at the cost end or the revenue generation end. The application chain and the public chain are quite different in terms of the degree of decentralization. The alliance chain is more suitable for the transformation of traditional industries, and BasS is built in the form of a coalition chain to serve existing corporate customers. As Jiang Guofei, the head of Ant Financial Services, said, using the distributed trust of blockchain, it is possible to achieve high synergy of business flow, information flow, logistics, and capital flow in a multi-center industry, reducing friction and saving costs.
Compared with consortium chain , the most fundamental change in the public chain is from multi-center to true decentralization. Such decentralization is realized by several layers of distributed systems. Blockchain is the product of distributed computing thoughts. The bottom layer of the public chain is distributed computing; on top of this, encryption technology and timestamps are added to form a distributed ledger that can record cryptocurrency transactions; using distributed computing power And distributed ledgers can further support its broader, multi-industry distributed value network and its accompanying new distributed business model. Under the first-level menu of the public chain, according to the different distribution technologies involved in the application, a secondary menu containing three types of applications can be derived:
Distributed computing applications, such as Golem, a computing rental platform based on Ethereum, a player launched by Thunder, IPFS, etc.
Distributed ledger application, encrypted payment tools such as Bitcoin, stable currency, Defi, etc. with stable coin as the medium;
Broadly distributed value network, pass-through economy, data economy, smart city, etc.
From the blockchain technology itself, it is possible to effectively use the blockchain, generate a reasonable and valuable DApp, and build a DApp ecosystem based on the technical architecture of the blockchain. Most of the current blockchain technology can only support a specific application of a certain level menu in the DApp menu. For example, Hyper Ledger can only solve the industry problem corresponding to the alliance chain, and Bitcoin is not only decentralized currency, but also Difficult to support more applications. By joining the smart contract, Ethereum is the most hopeful to support the DApp ecological infrastructure, but it is still in a slow growth stage due to its performance.
At present, it seems relatively feasible to build parallel blockchain technology if you want to build an infrastructure that can accommodate alliance chains, use distributed computing power on a large scale, support multiple distributed ledgers, and support generalized distributed value networks. Parallel blockchain technology can allow multiple sub-chains to coexist, is extremely inclusive; and the performance and scalability limitations are completely broken through parallelism; parallel chain technology can allow asset cross-chain interaction between multiple books, which is beneficial to The decentralized financial network with cryptocurrency as the general equivalent is developed and on this basis, the blockchain technology is further developed in various industries, thus forming a new generation value network based on blockchain. At present, Ethereum 2.0, Baidu Super Chain, Cosmos and Polkadot have adopted the concept of parallel blockchain. Among many projects, Paralism is the first invention applicable to parallel blockchain consensus algorithm and superblock protocol. Has obtained relevant patents. Paralism application platform based on parallel blockchain technology has been opened to support various applications in the DApp menu.
