Incremental blockchain

3. 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.

4. 1. When building a set of accounts
2. An account set has only one functional currency. If you want to record multiple currencies in the transaction processing layer, use MRC; If it is not needed, it can be realized with conversion function or account set consolidation function
3. Of course, foreign exchange adjustment is for the reporting currency, so the report of each reporting currency should be the result of revaluation.

5. In September of the same year, a blockchain technology enterprise in Shanghai launched the first blockchain combined with shared travel platform alpha free riding. More than 600000 users went online in March, and 1 million users have been obtained so far. As one of the advanced information technologies advocated by the state, blockchain technology is expected to solve the problem of travel safety e to its decentralization, non tampering and openness. This enterprise, which has been established for less than a year, has reached a strategic cooperation with Xunlei chain, an open platform of Xunlei's blockchain, in February 2019. It encrypts the user's travel data in the whole process and saves it to the blockchain according to the time stamp of the event. Every change in the order status will also be recorded to the blockchain, thus forming an information certificate. On the one hand, users' travel behavior data can be analyzed and processed, and credit scores can be made. Alpha free rider has zero tolerance for fraud, non-compliance and other dishonest behaviors, and records these bad behaviors through blockchain technology to give warning. On the other hand, it can be retained as tamperable evidence. Once there is a crisis or dispute in the future, it can accurately track and provide evidence, so as to further ensure the safety of travel
compared with the giants, Alfa, a grassroots travel platform, advocates free platform fees and no price difference travel. At present, in both the first and second tier cities and the third and fourth tier cities, in addition to the vehicles that have joined the online car Hailing platform, the illegal operation of black cars still exists, which has laid a huge potential safety hazard. Some car owners in order to avoid platform fees, desperate to jump single pick-up. Alpha free ride platform fee, and the introction of a special insurance ride. On the one hand, it reces the probability of vehicle owners' single skipping behavior; on the other hand, it enables the vehicle owners on the way to join a compliant and comfortable platform to receive orders on the way and ensure driving safety through blockchain technology. It is understood that alpha free riding is the first platform in China to propose free platform fee. In any case, this landmark experiment may bring about greater changes in the monopolized travel instry
blockchain digital token improves user stickiness
for the whole instry, how to retain existing users has become a common problem. In the past, the huge promotion costs of fast and Didi, didi and Uber competed for incremental users and drivers; And now the promotion cost is that each platform tries to keep its own car owners as much as possible, but the promotion cost may be a chicken feather. Compared with large-scale money burning subsidies and money burning advertisements, alpha free riding innovates and introces a bonus incentive policy, so that both owners and passengers have the opportunity to get a bonus after completing their trip. According to the relevant person in charge of Alfa Freewheeler, Hongfen is a token based on blockchain technology. The platform distributes 70% of the promotion fees and platform revenue to the users who hold the token. In addition to enjoying the cash reward of the platform every day, it can also be converted into an ecological universal voucher - work points, which can be used to trade second-hand idle goods, take a taxi to dect the fare, and use the work points to transfer the information Shopping mall procts exchange, etc. In the future, a richer ecosystem will be established to improve the use value of work points. Truly integrate the interests of car owners, passengers and platforms. Let the active users who actively contribute to the community get appropriate returns, and build a travel integrity community.

6. Blockchain games emerge in endlessly. Now the hot ones are encryption heroes on Ethereum, EOS knights on EOS, epic dragons on wave field, and many fun games to watch in spider store

7. Everyone has his own point of view
companies and institutions that want to break away from bitcoin or bitcoin payment applications to build small-scale, private or special-purpose distributed general ledger will detract from the original innovation of blockchain in two important aspects. First, they use other economic means (such as POS) to replace the pow mechanism of bitcoin network, which reces the size of the mine pool and destroys the tamper resistance of the blockchain. Second, if they add some commands and controls (such as permissions) to the original blockchain, the reason for blockchain's existence will become blurred, and the incremental margin of security seems to be larger
projects such as Ethereum, decent and lightcoin are still promising for bitcoin.

8. Yes, look at the bottom technology of Ali Alipay, there is the use of block chain technology.
