I have heard that the earliest blockchain project is in Chengdu?

        "Nine days out of Chengdu, thousands of households enter the painting." Since ancient times, I do not know how many literati and poets have written for it, leaving famous works to be handed down for generations. Today, when we comb the urban gene and historical context of Chengdu from Kuan Zhai alley, Chunxi Road to Yuanyang Taigu lane, we will find that the best way to open Chengdu is actually four words, namely "culture" and "innovation". As the temperament and soul of the city, Tianfu culture grew up in Bashan and SHUSHUI. It has not only the simple and elegant legacy, but also the fashionable and open bearing and the mind of embracing all rivers. On October 14, the 14th CSDN blockchain Technology Salon will come to such a city with strong cultural atmosphere and scientific and technological innovation as scheduled& mdash; Chengdu!.
 
        Chengdu can be said to be the birthplace of the earliest blockchain project. It originated from the famine and flourished in the streets and lanes. It is known as "mahjong". Why do you say so? In short, it has the following basic characteristics of the blockchain:. 1. There are four miners in a group. The miners who first collide with the correct hash value of 13 numbers can get the accounting right and get rewards. 2. It cannot be tampered with. Because convincing the other three people requires too much calculation and physical strength. 3. Typical value Internet. The value in my pocket didn't last eight times, so I went to their pocket. 4. Decentralized, everyone can be Zhuang, which is completely point-to-point. 5. Utxo, unspent transaction expenses.
 
        It can be seen that the blockchain not only originated early in Chengdu, but now it is spreading in full swing! Therefore, in this activity, let's carry the feelings of Chengdu and hum the ditty of "Chengdu": "walk with me in the streets of Chengdu, whoo ~ whoo ~", and witness the enthusiasm of Chengdu developers together!. Returning to the theme of this issue's blockchain salon, although blockchain is still a hot topic in the streets and lanes, and the momentum of technology development continues to rise, which brings us great imagination and subversive ability, DAPP based on blockchain technology is still in its infancy, and there is no DAPP with large-scale practical application value. For most developers, DAPP is a gold mine that needs to be developed!.
 
        DAPP in the blockchain 3.0 era is a blueprint for the future blockchain world described by blockchain technologies such as consensus mechanism, smart contract and cross chain integration. It can improve user experience and reduce development difficulty. From the perspective of reality, although many enterprises are exploring the application of blockchain technology and have also adopted blockchain encryption and distributed technology, there is no large-scale operation in the application process, which makes the relevant events unable to be verified by large-scale people, and the trust required by the resulting applications is difficult to reach a high level. Therefore, many applications are only technical blockchains, Instead of the blockchain on the application, the blockchain does not play a real role.
 
        CSDN, the world's largest Chinese developer community, has initiated and held "CSDN blockchain Technology Series Salon" in response to the strong demand of technology developers since January 2018. Currently, the 10 salons have covered 9000 people, all of whom are high-quality or potential technical talents in the industry. Since the 11th issue (August 2018), we officially opened the "CSDN blockchain Technology Salon Super City sharing meeting". This CSDN blockchain Technology Salon will be held in Chengdu, the "land of abundance". With the theme of "blockchain core technology and DAPP development", focusing on the core technology of blockchain, development trends and challenges, smart contracts, DAPP development, "blockchain +" and other contents, four blockchain technology experts will be invited to give in-depth analysis to blockchain technology developers and enthusiasts in the form of lectures and interactive discussions, And share some feasible solutions and the opportunities and challenges faced by the blockchain at this stage.
