Sharding of blockchain expansion scheme

1. The increase of blockchain network information is bound to need expansion, but it is not limited to a BTC public chain. No matter which public chain develops to a certain stage, it needs expansion technical support network. Therefore, it can be said that expansion is a necessary link for the implementation of blockchain scheme
the expansion of blockchain is the general trend, but there are differences in the specific operation. According to the different levels of blockchain architecture, the instry has proposed a number of expansion solutions: first, optimize the data transmission protocol for the underlying data layer of blockchain, do not change the upper structure of blockchain, and improve the scalability, such as bloxroute, the 0-layer expansion scheme of blockchain; The second is to change the data structure and consensus algorithm to improve the scalability of the basic protocol of blockchain, such as DAG (directed acyclic graph), fragmentation, dpos algorithm, etc; Third, aiming at the application level, such as side chain, sub chain, state channel lightning network and so on, part of the on chain transactions are transferred to the off chain execution to rece the on chain processing pressure and improve the overall efficiency.

2. The blockchain browser is the main window to browse the blockchain information, and the content recorded in each block can be viewed from the blockchain browser. Generally, digital asset users will use blockchain browser to query the transaction information recorded in the block. For example, the blockchain browser scheme developed by Yingtang Zhongchuang is mainly used to record in detail the confirmation process of each block, the generation and distribution process of digital currency, and the circulation of digital currency between each block, so as to more completely and publicly disclose the stock, increment, turnover rate and other information of digital currency, The only thing hidden is the owner behind each block.

3. yes. In 2017, the size of the capacity hit this "invisible wall.". Soaring costs have made bitcoin unreliable. Some users can't confirm their transactions even after waiting for many days. Bitcoin stopped growing. Many users, businesses, enterprises and investors have abandoned bitcoin. Its market share in many virtual currencies also dropped rapidly from 95% to 40%.

4. It's hammered out, and it's on the 60th floor. How can you get to the 108th floor and still don't know how to get the sage's stone? The number of layers of sage's stone in the spring mine is 60102123152155171190202222231 ~ 255. There is only one stone on each floor, and it won't appear in the eight blocks around the stairs and a circle against the wall

5. The format of the transfer contract is: Party A: (signature, address, ID card, etc.) Party B: (signature, address, ID card, etc.) specific terms: name, existing form, existing location, value and other delivery methods of the goods Dispute resolution can be divided into virtual currency transfer agreement

6. Heaton blockchain, established in October 2019, has a strong faculty.

7. The structure is divided into three levels: (1) sec structure 2) SEC service layer, as the middle layer, provides the role of transaction gateway for the interaction of Web protocols inside and outside the chain 3) The upper layer is sec application service layer, which provides API interface, web application development, DAPP development framework and bottom application capabilities.
