With Bitcoin popular people on the block chain is a term familiar to every day, but areas of the block chain as a new technology that can be applied is very wide, not limited to the issue of tokens, but will be applied to all field to bring a smart and convenient.
First, the block chain + finance
in the financial sector, is expected to be able to block chain pain points and solve the difficulties in the field of payment, such as can reduce the complexity of the transaction, the transaction end-to enhance the speed and reduce the cost of communication in the transaction process and improve transaction records transparency and non-tamper resistance. Reconciliation between financial institutions, especially cross-border financial institutions, clearing and settlement costs have been high, as well as complex manual processes, and the block chain technology and traceability data can not be tampered with, its application helps to reduce the financial cost reconciliation cost and solve a dispute between the institutions, can significantly improve processing speed and efficiency of payment services, but also the small cross-border payments possible.
Only commercial banks to seize the initiative, strive for a greater share of the business in order to maintain profits. For the latter, the development of existing commercial bank block chain has two advantages. One advantage of regulatory costs, that cash-strapped start-up companies, commercial banks are better able to digest and deal with regulators to obtain and maintain licenses compared to the huge costs associated. Second, consumers trust the advantage that most consumers do not understand the block chain technology, a veteran commercial banks long-term accumulation of reputation can reduce concerns about their use of these innovative financial products. 
Second, the block chain + game
a long time, the game industry has been a headache for some illnesses, such as: the proliferation of plug, gradually shorten the life cycle, the lack of protection of virtual property, the monopoly of distribution channels, divided into R & D and CP low and so on. However, from the theoretical level to talk about, block chain technology once mature, these problems will be solved.
Block chain in the gaming industry, the most immediate use is to block chain can use technology to create a decentralized gaming platform, Block Chaining game platform game platform to encourage people to participate in the form of issuing tokens. To attract attention to events organized by gaming platform. There is the application of technology to build the block chain distribution platform game, breaking the traditional monopoly of resources distribution platform, so that fair and open distribution model.
In iveryX open platform has been added ivo game world to play the game can earn VRY, other formats may be on the inside game to earn VRY buy props, and now game development is a big cake, if you can iveryone the promotion of the game up, it will break through the traditional mode of the game.
Third, the block chain + supply chain
block chain and supply chain can be described as a natural fit, first of traceability; cargo tracking information may be beginning to end traceability through the block chain. Followed by non-tamper resistance; This allows for control of the production date of the package of goods, to avoid the phenomenon of illegal businesses to use the production date change fraud. Again is transparency, you can see all the information behind commodity production processes with the block chain technology, such as which farmers planting, when production when shipping and so on.
These advantages help block chain of the supply chain to improve end to end data transparency, reduce cost and risk, while effectively solve the information island phenomenon, open up the procurement, production, logistics, sales, chain of custody. 
Fourth, the block chain + copy protection
is now copyright ownership and copyright protection is a pressing issue, has not been an effective way to solve, but if the copyright and can block chain together, the problem can be solved, authors can upload their works (articles, music, pictures, videos, patent ........) related protocols to block the chain, then, would generate a hash value corresponding to the file . After the transaction, the encrypted hash value of the file can be inserted therein, when the transaction was packed into a block chain miners block, the block time stamp. This hash value of the digital certificate + timestamp will resolve to prove the existence and work timeliness of problem to some extent. Secondly, ownership tracking, the entire process traceability. Involved in all aspects of copyright and transactions, block chain can be recorded from start to finish, the whole process in order to achieve traceability, and the whole process is irreversible and can not be tampered with.
Block chain can also be used in the field of insurance, charity, networking, public services, future business model will change a lot, two iveryone now has begun to implement some of the features, many also came to planning and development in the future can subvert the social network a few years, we'll see.
