Ask about using blockchain products, is it safe?

It needs to be mentioned here that the basic system structure of the blockchain has the following network routing cryptographic algorithm script system consensus mechanism blockchain security issues, mainly by the script system to complete the script system, in the blockchain technology, which is a relatively abstract concept is also an extremely important function, in the blockchain, the reason why a valuable network can be formed depends on the script system, like the engine driven, blockchain, The so-called script of continuous data sending and receiving refers to the program of constituting rules and then confirming some systems in the system, the rules are fixed, for example, in the Bitcoin system, only Bitcoin can be sent and received, which is completed through the script program of Bitcoin, the system allows users to compile their own program rules, and then they can be deployed to the blockchain ledger, so that the functions of the entire blockchain system can be expanded, such as Ethereum is through this set of custom script system, In order to realize the function of smart contracts, then specific scenario applications or practical life cases, such as order logistics information, chain information.

Our company is cooperating with Shengshi Huacai, and the security is guaranteed, which is the use of bank-level user data encryption, dynamic identity verification, multi-level risk identification control, and transaction security; Wallet multi-layer encryption, offline cold storage, third-party custody of funds, layer by layer, to ensure the safety of funds.

Hi everyone, I am your knowledge quiz assistant - Zi Xiaochen. Recently, blockchain renaissance has been widely concerned and discussed. But there are a lot of people who don't know much about its security yet. So today we're going to talk about the security of blockchain.

First of all, would you like to hear an easy-to-understand parable? A friend of mine joked, "Blockchain is like a combination lock."

If you don't have a password, no one can open it. It's simple and funny, but it makes a lot of sense. Because the blockchain uses distributed ledger technology, data is stored in a huge network, and the transmission between each node uses asymmetric encryption, which makes the blockchain extremely secure, and third-party attacks are very difficult.

Secondly, of course, there are some security issues to be concerned about. For example, hacking tactics such as the "51% attack" can pose a threat to the blockchain. In addition, virtual currency trading venues, such as Bitcoin exchanges, also have security risks that need to be taken care of.

Therefore, when choosing a blockchain platform or participating in virtual currency transactions, you need to be more aware and carefully consider to avoid losses.

In short, blockchain is an open technology, which has huge advantages in ensuring data security and preventing tampering. But we also need to be vigilant about potential security risks and choose reliable platforms and exchanges to participate in cryptocurrency investment.

I hope mine can give you a better understanding of blockchain and its security issues. If you still have questions or want to share your experience, please feel free to send me a private message! Finally, don't forget to like and comment**, follow my articles, and more content is waiting for you!

The hottest topic at the beginning of the new year is blockchain, but there are still many people who are skeptical about its security and risks, so how about blockchain security? Blockchain risksWhat are they? Below we will answer them one by one, I hope you can help after reading it.

How about the integrity of blockchain security?

First of all, blockchain is a distributed database technology. Distributed technology primarily refers to storage architectures. The distributed architecture adopted by the blockchain not only stores the ledger data on each node, but also each node must contain the data of the entire ledger.

This thoroughly distributed architecture results in a high level of security, and no one can destroy all the nodes at the same time.

Second, blockchain technology can be tamper-proof through "blocks" and "chains". The unit of data stored by the blockchain is a block, and when each block is generated, it must contain the unique "feature value" of the previous block (which can be regarded as the ID card of the block), and each block is lined up strictly in the order of the generation time to form a "chain".

Security is a major feature of blockchain technology. However, from the perspective of privacy protection, the blockchain emphasizes openness and transparency, and any node has the right to operate according to the consensus algorithm, so it is not suitable for scenarios that need to protect data privacy.

What are the risks of blockchain?

1. Technical risks: For example, the launch of Ether was once in the limelight, but because it is a digital currency with smart contracts, there is a risk of hacker attacks due to the possible vulnerabilities of smart contracts. TheDAO, Ether's largest crowdfunding project, was hacked and lost more than $60 million.

2. Legal risks: The legitimacy of digital currency issuance, notarization and confirmation, and the legitimacy of evidence, including the legality of smart contracts, digital bills, bookkeeping and clearing, and equity crowdfunding, are still blank in China and other countries in the world.

3. Crime risk: using the issuance of digital currency and then absconding with the money, using digital currency for money laundering and illegal gambling, using its designed smart contracts and digital bills to defraud interests, using blockchain technology for anonymous crimes, etc., due to the current regulatory gap, it is possible to generate huge criminal risks.

That's all for you, how about blockchain security? What are the risks of blockchain? All of it.

At present, there is no clear law to prove the legality of blockchain investment in China, and there is no law prohibiting the development of blockchain, but there are also great legal risks under the appearance of high returns, so you need to be cautious.

First of all, due to its lack of supervision, most of its circulation and trading forms are similar to the issuance and listing of **, and there is the act of setting up an exchange for trading. First of all, due to its lack of supervision, most of its circulation and trading forms are similar to the issuance and listing of **, and there is the act of setting up an exchange for trading.

Its transaction flow and transaction results are not transparent, and it is difficult to regulate the problem when encountering a wandering posture.

Legal basis: Article 12 of the Company Law of the People's Republic of China.

The articles of association of the company shall stipulate that the company shall be registered in accordance with the law. The company may amend its articles of association and change its business scope, but it shall go through the registration of the change.

The company's business scope is subject to approval in accordance with laws and administrative regulations, and shall be approved in accordance with the law.

The Newton blockchain and Newton-based e-commerce Newton are community economic infrastructures that provide governance, collaboration, and incentives. Newton uses the basic technology, protocol layer and application layer blockchain technology architecture to build a community economy managed by non-profit clubs, replacing the traditional economy managed by closed for-profit companies, and practicing the vision of "everyone should benefit from the economy". Compared with traditional business, the transaction cost of the community economy is greatly reduced because there is no commercial intermediary.

The human-machine community composed of human and machine nodes pioneered by Newton can be calculated as newforce according to the degree of contribution to the ecology, so as to obtain corresponding new incentives according to the newforce value, and ensure that the economic beneficiaries cover service providers, consumers and other ecological participants. Newton has planned application scenarios such as chain retail, ** chain, agriculture, public welfare, games, and self-finance to serve the real economy.

Newmall, a chain merchant retail platform to be launched in 2019, is Newton's first commercial application scenario. Compared with traditional e-commerce, on the chain merchant retail platform, participants can receive new incentives for behaviors including but not limited to shopping, browsing advertisements, and promotions. Participants own their own data to prevent the leakage of consumer information.

For merchants, platform fees will be significantly reduced. In addition, Newmall is initiated by a non-profit organization, and Newmall will not retain any platform fees as profits, which will be incentivized to participants in the form of New in various ways.

Through the way of bookkeeping, the way of national bookkeeping ensures the authenticity of the data of the blockchain.

The security of the blockchain needs to be maintained by the majority of users.

The purpose of contract audit is mainly to check the standardization, routine vulnerabilities, security vulnerabilities, business logic vulnerabilities, etc., the most important thing is to reduce the normal operation of the business caused by the first class, followed by ensuring the safety of funds; The third aspect is also to reflect the "fairness, openness, impartiality and transparency" after the deployment of smart contracts. At the same time, it is also to reduce the possibility of being attacked by hackers. In addition, it minimizes the risk before the product goes live.

Auditing is of great significance to the development of blockchain: on the one hand, auditing can save security investment and reduce repair costs. Studies have shown that remediation costs about 30 times more when an app is released than during the design coding phase.

Therefore, changing passive protection to active defense and controlling potential safety hazards from the source can save costs to the greatest extent; On the other hand, audits can reduce system security risks. Repair the defects of the first layer in a timely manner through the first audit, so as to greatly improve the overall security of the system and avoid huge economic losses.
