Bandwidth requirements of blockchain

1. Nodes are the places where the blocks are connected, and the blocks need to be chained to be useful
core analysis:
1. Transparency, 2. Openness, 3. Information can not be tampered with, 4. Decentralization,
5. Detailed analysis
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
1. In a narrow sense, blockchain is a kind of chained data structure composed of data blocks connected in sequence according to the time sequence, and it can not be tampered with and forged by cryptography
2. Broadly speaking, blockchain technology uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, and uses cryptography to ensure the security of data transmission and access It is a new distributed infrastructure and computing method to program and operate data by using intelligent contract composed of automated script code.

2. According to the current talent demand in the blockchain field, it can be roughly divided into the following categories:
1. Build a distributed ledger application based on DLT technology to realize the business requirements of customers on DLT. At present, the more famous one in this field is REBO. So what does DLT mean? Just look at what REBO is doing
2. Develop your own application on the existing public chain. At present, most companies are doing this. This category is also characterized by low threshold, high business potential and low risk
3. Companies develop their own public chains, which have the greatest potential in the future, but also have the highest risks and technical difficulties
4. Blockchain ecological infrastructure. For example, mobile wallet, hardware cold wallet, trading platform, blockchain content platform and so on are the blockchain instries with the highest commercial profits at present. Relatively speaking, the threshold is low and the risk is low, but there are many competitors
if we start from technology, what languages and knowledge do we need to learn
for the first class, go language is necessary, because DLT is mainly based on go language, and it also needs to master certain application development ability, because it must be a piece of software rather than a bunch of command-line source programs delivered to customers. For the second category, the mainstream of smart contract is the solidness language of Ethereum smart contract, so if you want to enter the second category of enterprises, you need to start with Ethereum. The third type of public chain development, the mainstream is C + + and go, but there are also many famous projects are implemented in trust, such as: Facebook's Libra, fire coin's nervos and so on. In fact, the fourth category has little to do with blockchain technology, because development such as trading platform does not need blockchain technology
in addition to the above technical hard power, blockchain companies prefer "slash youth", that is, talents who master multi field knowledge at the same time, which can be divided into three categories: finance and blockchain, content operation and blockchain, community operation and blockchain. Among them, the third kind of talents is the rarest, because most technical talents are not good at communication and exchange. However, e to its distributed characteristics, blockchain especially needs the joint efforts of the community to create and maintain a chain
in the end, many people mistakenly think that blockchain is a brand new instry, and that blockchain is totally different from traditional fields. This is actually a big mistake. From what has been written above, you can also find that in the end, blockchain still needs to solve the actual needs in reality. The only difference is that the tools to solve the needs have changed, so don't think that only knowing blockchain can kill all sides, It is very important to have the basic knowledge of the requirement field
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry.

3.

China has started to establish a national standard for blockchain to promote the construction of blockchain standard system from top-level design, which is expected to be completed by the end of 2019 at the earliest

in this regard, Zhao Wu, founder of Beijing Huashun Xin'an Technology Co., Ltd., also said that although the blockchain has disruptive technology potential, we must realize that the blockchain is still in its infancy, far from reaching the stage of subverting the world

Yu Kequn stressed that the independent and controllable blockchain network is intended not to be controlled by others technically, but also to promote the healthy development of blockchain. Security is the future life of blockchain. Only its own security can make blockchain technology landing. This requires us to pay equal attention to the development of blockchain technology and its security attributes, even ahead of time

in this regard, Li Ming also said that an important part of the standard is the information security standard, which can also see the importance of security to blockchain technology. He also pointed out that the development of blockchain standards does not mean that it will rapidly promote the development of the instry, but give the instry certain guidance. Previously, China has suffered a lot in terms of international intellectual property rights and standards. In terms of blockchain, China has formed more than 200 patents in terms of international blockchain, and even stands in the forefront of world technology. Therefore, we also need to firmly grasp our right to speak

4. There are no specific requirements. It is recommended to experience the blockchain in bitmax. This platform has strong financial strength, security and technology, so it is very good to choose other countries for blockchain transactions.

5. Hello, to be exact, blockchain is a technology model, while server is a kind of hardware resource. There will be a combination of the two. For example, the combination of storage type server and blockchain improves information security
with the development of the Internet, data are stored in the storage server, the security of data can not help everyone's worry. Blockchain technology, using cryptography to ensure the security of data transmission and access, in the process of data extraction, can realize the centralized use of unstructured data required by various research, so as to make the storage server data secure
the 10th party provides IT hardware solutions for enterprises such as server leasing and sales, and has a wide range of cooperation instries, including Internet, blockchain, scientific research institutions, rendering design, intelligent manufacturing, etc.

6. DGC is really unreliable. It's been 20 days since the withdrawal. I think it's really unreliable. Sorry to die

7. Bitcoin is a kind of P2P virtual currency. Point to point transmission means a decentralized payment system. Bitcoin does not rely on specific currency institutions to issue. It is generated through a large number of calculations of specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole
P2P network to confirm and record all transactions< Bitcoin trading is carried out through bitcoin trading platform,
at present, the better bitcoin trading platforms in China are
okcoin, bitcoin China,
fire coin network, 796 trading network, etc. the capital of each company is different,
okcoin is based on Technology, and fire coin network pays more attention to user experience,
but in terms of professionalism,
okcoin is relatively good.

8. First, the POS + pod hybrid consensus mechanism of the exclusive game community greatly improves the efficiency and consistency of the public chain network
Second, community autonomy. All decisions are made by community members. Under the hybrid consensus mechanism, both POS krypton players and pod technology players have higher yield and discourse power, which effectively avoids the impact of centralized computing power and financial resources on the whole game ecology, and thus reces the risk of bifurcation. If a node wants to propose a bifurcation for a certain protocol or standard, all nodes need to participate in the voting. If the pod + POS weighted value of the voting result exceeds 50%, the system defaults to the chain with high weighted value as the effective chain, and all nodes will migrate to the new chain mining at the time agreed in the voting result
thirdly, because game players have requirements for the performance and bandwidth of hardware devices, vs public chain sets the node players involved in accounting into two categories: full node and light node. Players can manually switch between full node and light node. Generally, light node mode is adopted in the process of the game to provide more hardware support for the game, and full node mode is started after the end of the game and ring the hang up period
fourthly, all the transaction rights in the game come from the players. Only after the players are authorized by the exclusive secret key, the game assets can be circulated. At the same time, all transaction data are encrypted by ECC (elliptic encryption algorithm), which is a modern cryptography technology, to ensure the information security of blockchain
fifthly, as a vertical public chain in the game field, vs will first complete the overall solution of decentralized game proction, virtual asset distribution and token economy operation. It includes game engine, developer environment, standard SDK, etc., which reces the difficulty and threshold for game developers to enter blockchain game development from various environments, greatly reces the workload and cost of game development team, and also makes vs public chain highly scalable.

9. It's hard for a person to take it down. It's not easy to develop a small exchange
