❶ What are the platform projects in blockchain projects?

The second category of blockchain projects is platform projects. What are the characteristics of platform blockchain projects? What are the typical representatives? The second category of blockchain projects is the platform category. The main function of platform projects is to establish a technical platform to meet the technical requirements required for the development of various blockchain applications. Simply put, platform applications allow developers to directly issue digital assets, write smart contracts, etc. on the blockchain. A smart contract is a computer program that runs on a blockchain database and can execute itself under conditions set by its source code. For example, if you develop a smart contract based on a house rental agreement on the blockchain, when the owner receives the rent, it will trigger automatic execution and give the apartment's security key to the tenant. The main function of platform blockchain projects is to establish an underlying technology platform and allow developers to develop applications on the underlying technology platform. A considerable number of platforms are still under development. As of January 2018, the largest market value is Ethereum. .

International problem: cross-chain technology

In order to solve the problem of information islands in the traditional Internet world, blockchain uses decentralized network structure, trying to achieve information sharing to solve the problem of data islands. However, with the emergence of many blockchain applications, the blockchain chains are not interoperable, causing the blockchain to also face this "isolated chain" dilemma. It is not in line with the original intention of the blockchain.

How to implement multi-chain coexistence on the same blockchain platform based on business functions, privacy protection, data isolation, performance and capacity expansion needs, etc. How to implement information and business interaction between blockchain platforms with inconsistent identity access mechanisms, information standards, and business forms. It is expected to become an important direction of development.

❹ What is the underlying technical architecture of Laikelib of Heshu Software blockchain technology?

Whenever we mentioned decentralized blockchain application platforms before, we always thought of foreign products, such as Ethereum. But when we talk about this topic today, I will think of Heshu Software, a blockchain technology R&D company in Shanghai, China. Laikelib is a new generation of decentralized, independent innovation, based on the combination of main chain and side chain technology. A safe, efficient and fully shared underlying architecture platform for diversified blockchain application development. It helps developers quickly create decentralized applications. From a model perspective, it is similar to Ethereum, both are blockchain services, but the implementation mechanism is slightly different. The biggest feature of Ethereum is that it greatly expands the functions of this script engine and lifts the restrictions on stack memory, function call depth, and script length. However, a big disadvantage of this is that the application code itself and the data generated by the application exist in the same In the blockchain chain, it causes the rapid expansion of the chain. But unlike blockchain systems, its scalability is not achieved through transaction scripts but by adding side chains. The advantage of this is that it reduces the difficulty of contract programming, avoids blockchain expansion, and allows each application to customize personalized block parameters.

❺ Want to know what are the development and applications of blockchain

The application scope of blockchain is spread across many industries

❻ What kind of currency is EOS

What kind of currency is EOS? Recently, virtual currencies have become very popular, and many friends have begun to pay attention to virtual currencies. Recently, the virtual currency EOS has become increasingly popular. Many friends still don’t know what kind of currency it is, so let’s take a look with the editor.
What currency is EOS?
Introduction to EOS
EOS is called Blockchain 3.0, which is different from Bitcoin.
Bitcoin does not rely on the issuance of a specific currency institution. It is generated through a large amount of calculations based on a specific algorithm. The Bitcoin economy is composed of Zhongmo Biduo nodes in the entire P2P network. A distributed database to confirm and record all transaction behaviors, and use cryptography design to ensure the security of all aspects of currency circulation.
P2P’s decentralized features and algorithm itself can ensure that it cannot be artificially manipulated by mass production of Bitcoins Manipulate currency value. Design based on cryptography allows Bitcoin to be transferred or paid only by real owners. This also ensures the anonymity of currency ownership and circulation transactions. The biggest difference between Bitcoin and other virtual currencies is its total quantity Very limited and extremely scarce.
eos is a token on eth. It is an operating system-like blockchain architecture platform developed under the leadership of blockchain wizard BM (Daniel Larimer), aiming to achieve distributed applications. Buried performance scaling.
EOS provides accounts, authentication, databases, asynchronous communication, and program scheduling on hundreds of CPUs or clusters. The final form of the technology is a blockchain architecture that The blockchain can support millions of transactions per second, and ordinary users do not need to pay usage fees.
The main features of EOS
1. EOS is somewhat similar to Microsoft's windows platform, by creating a developer-friendly area The underlying platform of the blockchain supports multiple applications running at the same time and provides underlying templates for developing dAPP.
2. EOS solves the problems of delay and data throughput through parallel chains and DPOS. EOS can handle thousands of transactions per second, while Bitcoin has about 7 transactions per second and Ethereum has 30-30 transactions per second. 40 pens.

(8) Extended reading on the underlying platform for blockchain developers:

Blockchain is far more than just a technology, it involves It is the spirit of "multi-party collaboration". In modern society, many things must rely on everyone's cooperation to achieve the effect of 1+1>2, but in cooperation, we need to try our best to avoid problems such as "information asymmetry."

Therefore, alliance members jointly keep accounts, share data, and make everything public to eliminate "information asymmetry" to protect everyone's interests and allow the business environment to develop healthily. If you do things honestly, you will get the benefits you deserve. If you cheat, it will be known to everyone and criticized by thousands of people. Technology is the foundation that helps realize this model. This is the more important "blockchain thinking".
