Link Dapp era - block line under the technical salon national line today officially opened in the beautiful Chengdu. The founder of EOS Canon Community, with the theme of “Meeting Dapp with EOS”, gave a warm speech at the conference. The edict said: “The blockchain is very hot. There are many people who know, but few people know it. Many people think that the blockchain has no practical application value. I think there are two main reasons. First, the development of the blockchain is difficult, and the current mature application is less. Second, the threshold is high and the use experience is poor. The blockchain may have a killer application in the blockchain of social, financial, and gaming domains. Together with the enterprise-level blockchain operating system EOS, it welcomes the Dapp era."

Then he entered the European chain CEO Harvey Wolf, future copyright project founder Zhao Yanyan, LemoChain team co-founder / COO Dylan Sutton, Chengdu Yingda Technology CEO Jiang Jiang, Fish.One project founder Cai Yuncheng, VA Studio founder Huang Wei The keynote speech.

Eurowell Technology CEO Harvey Wolf: "Data companies focused on service distributed applications (DAPP)"

Eurostar Technology is a data company focused on Service Distributed Applications (DAPP), and Eurowell Technology CEO Harvey Wolf Conference delivered a keynote speech entitled "Data Corporation Focusing on Service Distributed Applications (DAPP)". The old wolf began to contact Bitcoin in 2011 and participated in a number of blockchain community projects (Peercoin, Factom, BitShares), and has extensive experience in the blockchain industry.

OracleChain is a multi-blockchain decentralized Oracle technology platform that uses autonomous PoRD mechanisms to bring real-world data to the blockchain and use it as an infrastructure to serve other blockchain applications. By introducing external data into the blockchain to achieve data interoperability outside the chain, OracleChain will be the most efficient service delivery platform for acquiring out-of-chain data in the future blockchain world.

The old wolf said: "In addition to the functions of the PredicTIon Market application such as Augur and Gnosis, OracleChain can also support smart contract services with higher frequency access requirements for out-of-chain data, such as smart investment and other scenarios. OracelChain It is a data oracle in the EOS ecosystem. The oracle is the only way for smart contracts to obtain external information. The European chain also cooperates with Tianchi. OracleChain provides real-time transaction data of major digital currency exchanges to the world. The big sports event predictor service; I think how important the smart contract is, how important is OracelChain."

At the last Shenzhen offline salon meeting, the old wolf officially announced that the European chain launched PocketEOS. PocketEOS is developed by Beijing Easy Pocket Technology Co., Ltd., and is currently the first mobile-end application released on the EOS network, which is different from the current wallet single. The asset management function, while PocketEOS is also a smart contract application Dapp's traffic portal and application platform, allowing users to directly enter the blockchain 3.0 era.

In addition, the European chain also launched "Dapp-a questionable answer", which is the "knowledge payment" on the blockchain. The user gets the answer to the question by offering a reward for the digital currency. The old wolf said: "OracleChain is going to let this way Every piece of data and every point of view produces value."

Eurostar also launched the "OracleChain Daily Morning Post", which pushes the latest news of the blockchain and various activities to users every morning. Help users understand the latest developments in the blockchain industry.

Eurolink is also committed to the EOS block node. At present, OracleChain is also the Block Producer of the EOS test public network.

(Future copyright project founder Zhao Yanyan)

Next, Zhao Yanyan, the founder of the future copyright project, delivered a keynote speech on “Future Copyright Link Entertainment”. Zhao Lingyan said, “Future copyright is an EOS-based entertainment copyright intelligent trading platform. The decentralization of entertainment copyright entered in 2000. People's vision, that is, the emergence of P2P download technology, achieved peer-to-peer content sharing. At that time, Grokster provided P2P music download software and profited from it. Then Grokster was brought to court by seven giants such as MGM and Sony of Japan. With the emergence of eDonkey, eMule and other downloading software, these software still provide P2P download methods, but these music copyright giants ended up with the failure of centralized power."

Then Zhao Yanyan said: "The impact of the emergence of blockchain on traditional industries, people can not only freely transfer information, but also pass on value. Of course, blockchain will also change the creative and trading habits of entertainment creators, and will also greatly Reducing the cost of copyright protection, the future copyright is a global entertainment copyright intelligent trading platform based on EOS, which is dedicated to the global pan-entertainment IP copyright holders. It provides extremely low cost copyright deposit, copyright authentication and copyright. One-stop entertainment and entertainment services that are integrated into registration, copyright transactions, online rights protection, and content incubation."

Finally, the founder of the future copyright said: "The original intention of the founding is to create a network that freely conveys the value of art. The works do not necessarily need to be understood and recognized by everyone, but there must be opportunities to be known by everyone. Let everyone do what they want. It is the goal of our efforts."

LemoChain team co-founder / COO Dylan Sutton: "Dedicated to improving the efficiency of commercial data circulation"

(LemoChain team co-founder / COO Dylan Sutton)

Then LemoChain team co-founder / COO Dylan Sutton gave a keynote speech on "LemoChain: Intelligent Business Data CirculaTIon Infrastructure", said Dylan Sutton, a blockchain project dedicated to improving the efficiency of commercial data distribution, affiliated with Singapore's non-profit Foundation Lemo FoundaTIon LTD, Lemo builds an intelligent business infrastructure by providing decentralized user account systems, data distribution services, digital asset identification and user integrity agreements for developers and service providers in different industries. ”

Dylan said: "Many people think that data is a new era of oil. However, there are three different characteristics of data and oil. First, oil is not necessarily required by every business, but data is necessary for every business; second Oil is limited, but the data is infinite. Third, individuals can own data and use data to make money, but oil is not necessarily."

Dylan's example is enough to illustrate the importance of data, but the problem of centralized data makes it difficult for businesses and individuals to get revenue through data. Dylan said: "The emergence of blockchains has solved this problem very well. The chain has the characteristics of collective maintenance, distributed records, and data not tampering, which helps data to be confirmed and data to be realized. However, as far as the current business model is concerned, it is difficult for traditional businesses to quickly access the blockchain field. Dylan said, “First of all, the traditional industry lacks the corresponding channels to enter the blockchain field, followed by the lack of perfect advanced technology, and finally the development cost is too high.”

For this reason, Dylan said: "LemoChain is to provide intermediate media and tools to enter the blockchain for traditional merchants with data, to help businesses realize data validation and data realization quickly and at low cost. LemoChain will pass the Singapore Foundation To manage the ecological structure of code management, financial management, compensation management, update iterative management and privileged operation scope, so as to achieve global layout, attract talents from all walks of life in the United States, Britain, China and other countries to participate in the maintenance of LemoChain's ecology. ."

Jiang Ying, CEO of Chengdu Yingda Technology: “The Individual Medical Revolution in the Blockchain Era”

(Chengdu Yingda Technology CEO Jiang Jiang)

Then Jiang Ying, CEO of Chengdu Yingda Technology, delivered a keynote speech on “Individual Medical Revolution in the Blockchain Era”. Jiang Jiang said: “The blockchain evokes the individual medical revolution, and the HealthWallet project uses the underlying technology of blockchain+storage. To achieve decentralized medical information and patient data management systems to achieve individual medical revolution."

With the rapid development of science and technology, medical data has grown rapidly in many dimensions such as capacity, type and quantity. For example, X-ray, 3D nuclear magnetic, mammography, and 3DCT scans correspond to data volumes of 30M, 150M, 120M, and 1G, respectively, and gene sequencing reaches a data volume of hundreds of GB. In the new medical relationship, how should patients master their own medical data? Jiang Jiang said: "To combine the decentralized thinking and technology of blockchain, and to promote the focus of medical relations from hospitals to patients. It can also be said that blockchain is a catalyst for promoting the transformation of medical relations."

Then Jiang Jiang said: "Medical AI is 1000 times harder than Go, and Watson has been feeding for a long time. It is still very stupid. 'Feding' Watson should be given to the people, which is more efficient. Establish patient data based on the public. In the trading market, large companies can effectively obtain the data source of AI, and can develop AI customers and evaluate the effect of AI."

However, consumers are reluctant to share health information with technology companies. Because at the patient level, they have never obtained direct “benefits”, how to balance the privacy and security while sharing large-scale medical data?

Jiang Jiang said, “HeathWallet is a healthy digital asset and data sharing network platform based on Blockchain 3.0. Essentially, it is to do “self-control data” and “health health data sharing”, emphasizing that health data is One of the most important assets of a person's life, health data must have a "wallet" to keep."

Regarding the modular development of the HeathWallet project, Jiang Jiang said: "HeathWallet's early focus was on the incentive and middle layers of the blockchain." He added: "HealthWalletCore is the blockchain incentive layer for medical data, just like Filecoin and IPFS. Relationship."

The application scenario brought by HealthWalletCore is de-trusted. Jiang Jiang said that HeathWallet will complete two things in 2018:

1, HeathwalletStorage middleware, IPFS gene big data storage solution - has been officially released, poc test and promotion node; (with revenue plan);

2, doctor DAO mutual assistance contract (with revenue plan), landing in Huangpu District, Guangzhou in June.

In 2019, HeathWallet will launch a segmentation service for blockchain electronic medical records + specific application scenarios on the offline line (to create a closed-loop service for blockchain medical care, such as: mental illness prevention + blockchain + insurance).

Finally, Jiang Jiang said: "When medical AI can't serve human beings on a large scale, use blockchain technology to reconstruct the production relationship of the medical system, activate existing resources, promote trust, and solve real-world difficulties; This is also the mission of the HeathWallet project!"

Cai Yuncheng, founder of the Fish.One project: "blockchain game DreamWorks - Fish.One"

(Cai Yuncheng, founder of the Fish.One project)

Next, the founder of the Fish.One project, Cai Yuncheng, delivered a keynote speech on “Blockchain Game DreamWorks—Fish.One”. He said, “With the rapid development of computers and the Internet, the global online game market has grown from 2012. US$37.6 billion grew to US$83 billion in 2016. At the same time of development, the pain points in the traditional game field are also wide.

Cai Yuncheng, the founder of the Fish.One project, first introduced the development of traditional games. With the rapid development of computers and the Internet, the global online game market has grown from $37.6 billion in 2012 to $83 billion in 2016. However, there have been three pain points in the traditional game field:

1. The value is not public;

2. Black box operation, strong directivity;

3. The value of the item asset is depreciated.

What happens when the game encounters a blockchain? The game game numerical probability transparency can not be falsified; all the prop assets in the virtual world and the behavior are all on the chain, and the blockchain evolves into a highly free game world. As the user's size and demand increase, the items that the user produces in the game will gradually reflect the value.

Cai Yuncheng said that "the current status of blockchain + games: serious quality, high cost of games caused by the cost of the game, low TPS, can not deepen the gameplay, lack of community interaction." Based on this FISH.ONE proposed a corresponding solution : The concept of distributed operations, the development of games based on traditional methods (the second stage of the game), the fisherman, the fisherman and the team each have a clear follow-up profit point, the game guild system.

Finally, Cai Yuncheng introduced to you that FISH.ONE is a fishery game where the team sells a fixed number of fisheries. It is managed by the fishermen who purchase the fishery. All proceeds are owned by the fisherman. The digital assets in the game are fisheries. The fishery is based on the blockchain to issue ERC721 type digital asset assets, and the fishermen can trade freely. The characteristics of the blockchain guarantee the uniqueness of the asset. Players can create unions spontaneously within the game, and each union will generate a corresponding heat, loyalty, and contribution ranking. The top trade unions and their members will receive corresponding rewards.

VA Studio founder Huang Wei: "The exploration of blockchain gameplay"

(Va Studio founder Huang Wei)

VA Studio founder Huang Wei shared the keynote speech of “blockchain gameplay exploration” at the conference. Huang Wei from the blockchain game industry background, blockchain game core gameplay iteration, restricting game data chain factor, game The project examples and prospects were shared in five aspects.

Blockchain game industry background

Huang Wei said that on November 28, 2017, the blockchain game Ethereal Cat CryptoKitTIes was born, and in just a few weeks, it attracted the "eyes" of the world. After the hot market of CryptoKitties games, blockchain games have emerged, and at least one new blockchain game appears every day. The gameplay also experienced four major iterations, dozens of small changes.

Blockchain game core gameplay has been iterated four times

Huang Wei said, "The first is the blockchain game 1.0 era, the keyword is "collection + transaction", representing the game CryptoKitties, CryptoPunks; blockchain game 2.0 era, the keyword is "Ponzi-like", represented by Etheremon; The key words of the blockchain game 3.0 era are "fixed price, forced price increase", representative works are CryptoCelebrities, CryptoCountries; blockchain game 4.0 era keywords are "multiple mechanisms combined", representative works have World.Mycollect, CryptoCities and Gaming, RPG, battle, two yuan and many other games."

Factors that constrain game data chaining

Huang Wei said that there are three main factors that restrict the game data on the chain:

1. Processing speed: The data processing speed of the blockchain is slower than that of the centralized server. At this stage, the blockchain cannot meet the huge data interaction between the game user and the server.

2, handling fee: the uplink data needs to pay GAS, all the operations in the play are very many, such as upgrading, acquiring equipment, etc. If you want to go on the chain, then the handling fee will be a huge expenditure.

3. Version iteration: Games based on blockchain development cannot be modified once the game rules are set, and version iterations cannot be done. Good games are constantly adjusted, and not all of them are ok. If you find that there are problems with the previous settings, you can only re-develop one.

Based on the problems of the blockchain province, the game data is partially chained. Naturally, at this stage, VA Studio also tends to be a pseudo blockchain game. The game assets are on the chain, and most of the data such as game logic is not on the chain. This first solves the problem of frequent interaction, and also solves the problem of the cost of the chain. In addition, Huang Wei said, “Only putting core assets on the chain can also solve the iteration problem of the version.”

Prospect

Huang Wei said, "blockchain technology and decentralized applications will undoubtedly have a wider application in the game industry and bring more profound impact. In specific applications, due to data processing speed and transaction needs to pay high The GAS fee, so most games currently choose to put the game assets on the chain, and most of the game logic is not on the chain. In the future, the platform supporting the decentralized application will be more mature and the transaction cost will be lower. All parts of the game can be played on the chain, and users can play more entertaining blockchain games."

After the team's speech, it entered the round table of the offline salon. The roundtable discussion centered on the theme of “The development of the 2018 blockchain industry”. The pioneers of the blockchain industry focused on the many pieces raised on the spot. Chain related questions were answered.

Overall, the roundtable is the fascination and opportunity for the development of the 2018 blockchain industry, as well as some suggestions from the first-line technical practitioners of the blockchain industry to those who want to enter the blockchain industry.

After the round table, the guests took a group photo, and the Dapp era-block chain technical salon national line (Chengdu Station) officially came to an end in the poetic and picturesque Chengdu. After the salon meeting, the next meeting was the free collision of the guests. At the stage, this link to the Dapp era - the blockchain under the technical salon Chengdu has achieved a complete success.

Finally, I remind you that the OracleChain team is expected to hold the "Link Dapp Age - Blockchain Hackathon Marathon" in May. The old wolf said, "Welcome everyone to join a 'blockchain marathon'".
