1. Triporg travel: a travel service application using the underlying technology of blockchain, which can provide travel prepaid services such as train tickets and air tickets.
2. Blockchain is just a technology that anyone can use. Blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system. There is no underlying platform for blockchain now. If there is R3, it should be regarded as one. Decent, bitcoin and Ethereum are all relatively successful projects
3. LF CEO Ma Haobo said in the "cannon interview": the problems urgently solved by the underlying facilities of the next generation blockchain are very similar to those of Ethereum. It is an underlying decentralized computing platform. On the platform, users can easily deploy smart contracts and run them, but? LF thinks that Ethereum has three problems and hopes to solve them. The first is its overall low performance and TPS; Second, resources are not isolated. When crowdfunding for a certain contract is very popular, Ethereum network will block and other contracts cannot be executed; The third problem is reflected in the governance structure, who this blockchain belongs to, how it develops, and how to solve the problem of bifurcation.
4. Just to learn a little, Heshu software was founded in 2017. It has its own blockchain technology laboratory, focusing on blockchain technology scenarios and application development. For example, the underlying architecture of laikelib blockchain allows users to develop their own independent applications and systems on the chain, which is similar to Ethereum. The advantages of laikelib are small capacity, short block out time of 2 seconds, diversification and independent research and development. The response is still good, and they have set up a technical team composed of experts in the fields of data science, blockchain, cryptography and data analysis. The others are not clear. I hope they can help you and hope to adopt them!
5. Blockchain is a new decentralized protocol, which can safely store transactions or other data. Information can not be forged or tampered with, and can automatically execute smart contracts without the audit of any centralized organization. Transaction can be digital currency such as bitcoin, or digital assets such as creditor's rights, equity and right, which greatly reces the trust cost and accounting cost of real economy and redefines the property right system in the Internet era. At present, aelf is a well-known blockchain project of the underlying architecture, which represents the future development direction.
6. The projects of jinwowo network technology analysis blockchain are divided into three levels:
the top and easiest thing to do is the application layer. I can see two or three such projects every day, accounting for more than 95% of the whole market. But such companies often write a lot of technical things in the white paper. In fact, they also write in vain. This is purely for the purpose of collecting pages, because they don't need to talk about technology at all
the second type is the intermediate operation level, such as quantum chain and ant. This kind of project is similar to the operation procere, called the basic chain, which is used to run the application. This category is relatively small, and the proportion has dropped to less than 5%
the third category is more downward extension and lower level, such as standard chain and arcblock. This kind is even less. It's good to see two or three in a month. And some of them are not necessarily true, because there is really nothing to write about, and all fields are occupied by others, so someone will go in this direction.

7. Laikelib main chain: the main chain of laikelib mainly deals with the interaction between the application business model and the application scenario. Laikelib side chain: around the main chain, any application system can be developed in the side chain for users to use.
8. Aggregation chain refers to the innovative introction of "alliance chain + cross chain + public chain" aggregation chain technology architecture on the basis of long-term accumulated alliance chain technology, so as to realize the efficient, safe and low-cost flow of data and assets, and then practice the historical mission of enabling distributed economy.
9. Mine pool refers to:
as the computing level of the whole bitcoin network continues to rise exponentially, a single device or a small amount of computing power can not get the block reward provided by bitcoin network
after the computing power of the whole network has been improved to a certain extent, the low probability of getting rewards has prompted some geeks on "bitcoin talk" to develop a method that can combine a small amount of computing power and operate jointly. The website established in this way is called "mine pool"
extended data:
the existence of the mine pool reces the difficulty of mining bitcoin and other virtual digital currencies, reces the threshold of mining, and truly realizes the concept of bitcoin mining that everyone can participate in
but its disadvantages are also very obvious, because computing power is connected to the mine pool. As a mine pool, it will have a huge amount of computing power resources. In the bitcoin world, computing power represents the bookkeeping right, and computing power is everything. If the computing power of a single mine pool reaches more than 50%, it will be easy to launch 51% attacks on bitcoin and other similar virtual digital currencies, The consequences are very terrible:
the mine pool can make the mine pool with 49% of the remaining computing power have no harvest, instantly quit the competition and go bankrupt. The mine pool's computing power exceeds 50%. If 51% attack is launched, it will easily occupy all the effective computing power of the whole network
