St Zhongan blockchain
however, it's easy for people with an eye to see why there is no security layer? In fact, several key features of blockchain have already solved the security problem. First, the blockchain uses asymmetric encryption technology. In fact, encryption and decryption are different keys, namely public key and private key. In short, the public key is open to the public, while the private key is absolutely confidential
secondly, distributed bookkeeping is a way for blockchain to store data. It can also be understood as distributed storage, which is consistent with the concept of decentralization. In the form of ledger, there is no central ledger in the network, and the ledger is stored in each node. Each node is not only independent, but also can act as the central node. Therefore, the central node will not be attacked, leading to the loss of core books or data, and the whole network will not be paralyzed
moreover, tamper proof is the basic feature of blockchain. As long as the chain can not be modified, and can not be deleted. If it needs to be changed, based on the principle of transparency and openness, the whole network and all nodes need to be informed. Therefore, under the democratic mechanism, the possibility of tampering with data at will is very low. Therefore, blockchain technology is applied in various instries, such as finance, payment, traceability, games, etc., such as the network "universe", Tencent's "come together to catch the demon", and Zhongan Huanyu blockchain "Dr dragon hunt" are the safe and high-quality procts under the blockchain technology.
trend 1: blockchain technology is constantly updated and is developing in the direction of great integration
blockchain is a blockchain structure, which completes the clarity of ownership through encryption, and establishes trust through a large number of rendant storage at low cost, so the storage efficiency is very low. So many systems export the existing blockchain data to external storage
trend 2: the privacy protection mechanism of blockchain is diverse, which has become a key lubricant to activate commercial applications
there are many kinds of privacy protection, such as ring signature, multi signature, mixer, zero knowledge proof, homomorphic encryption and so on. MIT Technology Review rated perfect privacy protection as one of the top 10 breakthrough technologies, because privacy protection is a good lubricant for blockchain
trend 3: the development process of blockchain instry has been accelerated, and it has entered the theme of "from virtual to real"
it can be said that the blockchain has completed a lot of landing. With the acceleration of the development process of blockchain instry, the large-scale commercial application of blockchain technology in medical, judicial, instrial, energy and other fields will be started in the future
in addition, blockchain has a good development trend in games, such as Tencent's "catching demons together", the network's "universe", Zhongan Huanyu's "Dr dragon hunt", Netease's "Netease planet", and so on.
Currency digitization is the future trend, and the investment and financing events of blockchain instry continue to rise. On October 13, 18, the blockchain platform tzero of overstock, an American e-commerce giant, completed the issuance of securities token. Tzero raised $134 million through large amount of securities token financing, which was used for the construction and development of securities token, After being officially approved, tzero sto can raise funds in a way similar to equity crowdfunding, and exchange a certain proportion of equity and token. With the continuous participation of traditional enterprises, sto has moved from a small circle of blockchain to a broader mass world
from the popularity of ICO to the popularity of STO, the development speed of blockchain is also quite fast. So what is sto
sto (security token offering) refers to the issuance of securities type warrants, whose goal is to carry out the public issuance of warrants under a legal and compliant regulatory framework. At present, the governments of the United States and Singapore are actively introcing relevant laws and regulations, and there are a large number of exchanges, project parties and service platforms focusing on sto
sto mainly includes three factors, namely securities, warrants and issuance:
Security - ownership of the underlying assets with real value, such as stocks, real estate, funds or artworks. Usually, owners are provided with different financial rights, such as profit sharing rights, equity, dividends, voting rights, redemption rights, etc
token token token, circulating proof of rights and interests. The securities mentioned above must be associated with a specific form of expression. The form of expression of token is expected to evolve from the previous paper-based securities to the current paperless (traditional exchange securities company account records) to the advanced paperless (encrypted digital account records based on blockchain Technology) in the future
Offering refers to comparing IPO (the national designated exchange of traditional securities) and ITO (the ITO website that can be run by indivials). At present, the issuing platform is mainly the token exchange which is subject to the national supervision, and the issuing is subject to the supervision of regulatory agencies (such as SEC in the United States, Bafin in Germany, etc.), and issued in accordance with regulations (such as reg D, reg a +, reg s, reg CF of SEC), Investment users need to pass KYC and AML auditfrom the perspective of blockchain:
st is the token of securitization, which is an application of blockchain in the stage of 3.0
st is a rational choice from the virtual to the real
st is an effective way of chain reform
enterprises can realize the vision of issuing sto through vie
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.
