The 5th Shanghai Blockchain International Week has come to an end. During the three-day conference, Vitalik, founder of Ethereum, Gavin Wood, founder of Polkadot, Xiao Feng, chairman and general manager of Wanxiang Blockchain, Yao Qian, general manager of China Securities Depository and Clearing Corporation, and other industry celebrities gathered In Shanghai, discussions were held on hot topics such as DeFi, privacy, Web3.0, scaling, and the Internet of Things.
In the Demo Day on the first day, many project parties showed their current blockchain application scenarios. BlockBeats found several interesting projects. Let me share them with you. Maybe you can find some trends from them.
This is a recently popular Layer 0 project that aims to solve the long-standing scaling problem on the blockchain. In May, bloXroute announced the completion of its Simple Agreement for Future Tokens (SAFT) financing. Participating companies include Pantera, Coinbase Ventures, and Fenbushi Capital, a total of 11 investment institutions.
CovenantSQL
Aleksandar Kuzmanovic, co-founder and chief architect of bloXroute Labs, introduced the expansion design of bloXroute at the meeting. The problem with the current speed on the blockchain is that it may take 20 minutes to transmit a 30M block. The idea of bloXroute is that it may not be necessary to completely transmit the 30M block.
They marked the transaction and only transmitted the transaction. In this way, a 30M block may be compressed into 222 bytes, so that only these 222 bytes need to be transmitted in the network.
Using this method, the bloXroute team tested on BCH and found that the broadcast speed increased by 20 times for large blocks of 32M. On September 19, they announced the results of the public test on Ethereum, and found that the transmission speed of some nodes has doubled.

The CovenantSQL architecture is divided into two layers. The main chain is mainly for resource allocation and system governance, while the sub-chain is for data storage.
Taraxa
Founder Jing Mi deliberately distinguished the difference between CovenantSQL and IPFS. The storage objects of IPFS are mainly files, usually static files. And once the file is placed on the IPFS network, it can no longer be modified. But the database is different. The data in the decentralized database cannot be modified, but the modification history cannot be deleted at will.
CovenantSQL also demonstrated two applications in banking and healthcare.
There is something called "data blood" in the data system of traditional banks. Bank tracking data generally uses SAP and Oracle. Different departments of a bank will label the same user differently. CovenantSQL is used to trace the history of labels. Another application is the sharing of patient data between hospitals.
This is a project for positioning the Internet of Things, trying to solve the current data security and trust issues of the Internet of Things. This team from Silicon Valley believes that the current public chain technology is not perfect and cannot support the application of the second layer, so they first built a bottom layer by themselves.
Taraxa co-founder and CEO Steven Pu introduced two main technologies, which are relatively popular at present. One is to use BlockDAG to achieve scalability, and the other is to use PBFT consensus based on VRF random number verification to confirm blocks. With the support of this underlying technology, Taraxa has implemented some landing applications.
They partnered with international automakers in Japan to build a decentralized data marketplace. The Japanese government wants car companies to get user data, but users in other countries don't want the car companies to get their data. So Taraxa worked with the automaker to build a decentralized data marketplace.
Another application is parking lots. Japanese parking lots generally sign long-term contracts with users, so the efficiency of parking lots is very low. Taraxa partnered with two car parks to increase their ROI with parking sensors.

Copyright owner certificate system
The name of the project Copyright Home, as the name suggests, is to solve copyright issues through the blockchain. There are too many projects that want to use blockchain to solve copyright issues. Internet giants have also made similar attempts. Baidu's Totem and 360's Tuke are all applications for image copyright. This time, the copyright owner launched a copyright-related evidence deposit system.
This project is relatively easy to understand, and the logic is not complicated. It is the deposit and collection of electronic certificates and the chaining of evidence. However, it is worth mentioning the historical development of domestic use of electronic deposit certificates on the chain.
In June 2018, the Hangzhou Internet Court used blockchain technology as a way to confirm electronic certificates. This is the first time in China that electronic certificates using blockchain technology have legal benefits.
In April of this year, the copyright owner's evidence storage system was used in the first case involving blockchain evidence storage in the newly established Beijing Internet Court. With the popularity of this kind of blockchain forensics, Internet courts are less and less handling such cases, because under the authority of blockchain forensics, the parties to the dispute often settle before the court.
