㈠ What is blockchain technology? What exactly is blockchain? What is blockchain?

In a narrow sense, blockchain is a way to store data in A chained data structure composed of blocks connected in sequence, and a cryptographically guaranteed distributed ledger that cannot be tampered with or forged.

Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, and uses cryptography to ensure data transmission and access. It is a new distributed infrastructure and computing method that uses smart contracts composed of automated script codes to program and operate data securely.

[Infrastructure]

Generally speaking, the blockchain system consists of data layer, network layer, consensus layer, incentive layer, contract layer and application layer composition. Among them, the data layer encapsulates the underlying data blocks and related basic data and basic algorithms such as data encryption and timestamps; the network layer includes distributed networking mechanisms, data dissemination mechanisms, and data verification mechanisms; the consensus layer mainly encapsulates network nodes Various consensus algorithms; the incentive layer integrates economic factors into the blockchain technology system, mainly including the issuance mechanism and distribution mechanism of economic incentives; the contract layer mainly encapsulates various scripts, algorithms and smart contracts, and is the core of the blockchain The basis of programmable features; the application layer encapsulates various application scenarios and cases of the blockchain. In this model, the chain block structure based on timestamps, the consensus mechanism of distributed nodes, economic incentives based on consensus computing power, and flexible programmable smart contracts are the most representative innovations of blockchain technology.

Extended information:

[Blockchain core technology]

Blockchain mainly solves the trust and security issues of transactions, so it addresses this issue Four technological innovations:

1. Distributed ledger means that transaction accounting is completed by multiple nodes distributed in different places, and each node records a complete account, so they all Can participate in supervising the legality of transactions and can also jointly testify for them.

The uniqueness of blockchain's distributed storage is mainly reflected in two aspects: First, each node of the blockchain stores complete data according to the block chain structure. Traditional distributed storage generally stores The data is divided into multiple parts for storage according to certain rules. Second, the storage of each node in the blockchain is independent and has equal status, relying on the consensus mechanism to ensure the consistency of storage, while traditional distributed storage generally synchronizes data to other backup nodes through the central node.

No node can record ledger data independently, thus avoiding the possibility of a single bookkeeper being controlled or bribed to record false accounts. Also because there are enough accounting nodes, theoretically speaking, the accounts will not be lost unless all nodes are destroyed, thereby ensuring the security of the accounting data.

2. Asymmetric encryption and authorization technology, the transaction information stored on the blockchain is public, but the accountIdentity information is highly encrypted and can only be accessed with the authorization of the data owner, thus ensuring data security and personal privacy.

3. The consensus mechanism is how all accounting nodes reach a consensus to determine the validity of a record. This is both a means of identification and a means of preventing tampering. Blockchain proposes four different consensus mechanisms, which are suitable for different application scenarios and strike a balance between efficiency and security.

The consensus mechanism of the blockchain has the characteristics of "the minority obeys the majority" and "everyone is equal". "The minority obeys the majority" does not entirely refer to the number of nodes, but can also be the computing power and the number of shares. Or other characteristic quantities that the computer can compare. "Everyone is equal" means that when a node meets the conditions, all nodes have the right to give priority to the consensus result, which will be directly recognized by other nodes and may eventually become the final consensus result.

4. Smart contracts. Smart contracts are based on these trustworthy and non-tamperable data and can automatically execute some predefined rules and terms. Take insurance as an example. If everyone's information (including medical information and risk occurrence information) is true and trustworthy, it will be easy to automate claims settlement in some standardized insurance products.

In the daily business of insurance companies, although transactions are not as frequent as those in the banking and securities industries, the reliance on trusted data continues unabated. Therefore, the author believes that using blockchain technology from the perspective of data management can effectively help insurance companies improve their risk management capabilities. Specifically speaking, it is mainly divided into risk management of policyholders and risk supervision of insurance companies.

㈡ Blockchain 3.0 ecosystem, giving you a brief understanding of the ecological order

Blockchain 3.0 ecological operation The system is also called "public chain", which is equivalent to the infrastructure of the blockchain world. Developing blockchain application scenarios on the public chain is like developing APP on a complete set of mobile APP development software. The development of blockchain technology or applications provides considerable convenience. Therefore, the underlying ecological operating system developed based on blockchain technology has always been the focus of the development of blockchain technology.

Among many public blockchain chains, the emerging Ecological Order (ECOL) is often not understood by people. What is the Ecological Order? What is the difference between Ecological Order and other blockchain platforms and public chains? So, let’s find out together below!

Ecological Order (ECOL) aims at blockchain 3.0 and brings together many domestic and foreign experts, scholars and elites in the fields of blockchain, big data, Internet of Things, artificial intelligence (AI) and other fields. Programmers join forces to jointly conceive the intelligent blockchain 3.0 system with a scientific and rigorous attitude. It emerged to solve the many problems of current blockchain technology such as being unfriendly, inefficient, low scalable, non-interoperable, and difficult to upgrade, and to build a pluggable, transferable, and arrangeable modular, intelligent, Efficiency,Solutions for effectively decentralized blockchain ecosystem and application scenarios.

Ecological Order (ECOL) has the following design features:

Parallel expansion - parallel processing of network sharding

Ecological Order (ECOL) Using parallel expansion technology, through "main chain + side chain" multi-chain parallel, cross-chain communication and other operating mechanisms, the business of the main chain and side chain is separated to meet the demand of tens of millions of TPS. Network sharding parallel processing brings continuous scalability and a reliable high-performance foundation to your applications. Existing single-threaded functionality forces each application to share the capacity and performance of a single-threaded blockchain, creates hard scaling limits, and ultimately suffers from network congestion that can cause platform-wide downtime.

Self-evolution - a modular intelligent system coordinated by artificial intelligence

Ecological Order (ECOL) adds artificial intelligence modules to the basic functional modules of the network main chain, artificial intelligence The intelligent module will observe the changes in the network, learn from the packaging and broadcasting, the addition and deletion of modules, the generation of side chains, and the solution of problems in the network and continue to grow, simulate various situations and Handle it by yourself and eventually grow into a professional and impartial "blockchain network artificial intelligence expert". Each node can achieve mutual trust by trusting artificial intelligence and solve problems such as low efficiency caused by the innate lack of mutual trust between nodes.

Simplifying blockchain technology application development - functional modularization

Ecological Order (ECOL) can package different functional modules in the blockchain separately, in a modular Basically, the development cost and difficulty of the Ecological Order side chain will decrease linearly compared with traditional blockchain technology. The lower development threshold also makes the Ecological Order's side chain technology more easily penetrate into all walks of life.

㈢ What is cross-chain technology

Cross-chain, as the name suggests, is to allow value to cross the chain through technical means and barriers between chains for direct circulation. Cross-chain is essentially the same as currency exchange. Cross-chain does not change the total value on each blockchain, it is just an exchange between different holders.

Cross-chain is a complex process, which requires the chain to obtain and verify information outside the chain, and requires nodes to have independent verification capabilities, etc. There are four main implementation modes of cross-chain technology: notary mode, side chain/relay, hash locking and distributed private key control, etc.

1. Notary scheme

Notary schemes are the simplest way to interoperate between chains. They are managed by one or a group of trusted persons. group to declare chain A against BSomething happened on the chain. The more famous application in the notary model is the Ripple Interledger protocol.

The Interledger protocol was proposed by Ripple Labs in 2012. It connects two different blockchains (accounting systems) through a third-party "connector" or "validator" so that They can exchange currencies freely. In this process, the accounting system does not need to trust the "connector" because the protocol uses cryptographic algorithms to create fund custody for the two accounting systems. Only when all participants reach a consensus on the transaction can they trade with each other.

2. Side chain/relay

Side chain is also a blockchain. It can verify data from other blockchains and enable the exchange of Bitcoin and other assets. Blockchains are transferred to each other, forming a new and open development platform. The Ethereum Raiden Network, a very popular project some time ago, uses sidechain technology. When participants using the Raiden Network transfer funds to each other, they do not need to confirm the transaction through the Ethereum main chain. Instead, they create micropayment channels between participants and complete it under the main chain. The main applications of side chains are: RSK, BTC Relay, etc.

We have already talked about side chain technology before. Friends who want to know more can click here to review.

3. Hash Locking

Hash-locking originated from the HTLC (Hashed TimeLock Contract) of the Lightning Network. It forms a smart contract to ensure that transfers between any two people can be realized through a "payment" channel, fulfilling the role of "intermediary". Both parties to the transaction first freeze part of the money through smart contracts and provide an Hsah value. Whoever can match the Hash value within the contract setting time will get this part of the frozen money.

Although hash locking realizes the exchange of cross-chain assets and can support the mortgage of assets in most scenarios, it does not realize the transfer of cross-chain assets, let alone realize cross-chain contracts, so its application scenarios Relatively restricted.

4. Distributed private key control

Distributed private key control uses a protocol-based built-in asset template and deploys it based on cross-chain transaction information New smart contracts create new assets. When a registered asset is transferred from the original chain to a cross-chain, the cross-chain node will issue corresponding equivalent tokens to the user in the existing contract.

The operations to implement and release distributed control rights management are called: lock-in and lock-out. Locking is the process of realizing distributed control rights management and asset mapping for all digital assets controlled by keys. At this time, it is necessary to entrust the decentralized network to take charge of the user's private key.Master the private key of the proxy assets on the cross-chain. When unlocked, control of the digital asset is returned to the owner. The main applications of distributed private key control include: WanChain, FUSION, etc.

㈣ The XO public chain has aroused global heated discussion and may lead the third generation of blockchain

Blockchain technology has experienced more than ten years of development since 2008. The representative public chain of V1.0 and V2.0 in the industry. So what kind of blockchain can be called the third generation blockchain, and what technical characteristics and advantages does it have?

In the development process of the second-generation blockchain, there has been an explosion of public chains and alliance chains. Each blockchain is like an island of information, each working independently. , and the XO public chain perfectly solves this problem through cross-chain technology. The XO public chain has independently designed a set of CCP (Cross-Chain Protocol) cross-chain protocols to achieve communication and transactions with other blockchains through multi-chain two-way anchoring technology. It has now achieved cross-chain sharing with the Bitcoin main network. , and other public chains will be opened in the future. At present, BTC can already enjoy a second-level payment experience in the XO public chain, and the mining fee is less than one thousandth of the original.

The technical characteristics and high-quality performance of the XO public chain determine that it can become an infrastructure in the blockchain field. Developers can quickly create digital assets and develop DApps, which will enable the XO public chain to evolve independently. In order to apply the ecology, it can exert value in the fields of culture, finance, logistics, chain merchants, charity, etc., especially in cross-border payment and cross-chain transactions. Based on the XO public chain, blockchain construction can be completed in three steps, providing a variety of optional consensus mechanisms and more than 50 blockchain customization parameters, and providing more than 200 API interfaces for DApps developers. This series of measures and signs indicate that the XO public chain is a typical representative of the third-generation blockchain. It not only integrates the technical advantages of the first-generation blockchain and the second-generation blockchain, but also realizes the implementation of blockchain technology. Major breakthroughs and cross-chain integration are expected to lead the next decade of the blockchain era.

㈤ Full analysis of Alipay’s mysterious blockchain product “Open Alliance Chain”, the era of universal access to the chain is here

The mysterious blockchain product that Ant has announced for many days has finally been unveiled.

On April 16, Ant officially announced its new blockchain product "Open Alliance Chain". The "Open Alliance Chain" claims to be a universal chain-linking product that "doesn't require a chain and can be uploaded quickly and at low cost" mainly for small and medium-sized enterprises and developers. It focuses on helping developers quickly deploy and develop blockchain-related applications.

According to Ant Blockchain Jin Ge, the "Open Alliance Chain" began testing in December last year. After more than three months of public testing, it has accumulated thousands of customers and developers (active ratio More than 10%), dozens of DApps have been built on the product.

This official announcement also heralds the official transition of the "Open Alliance Chain" from public beta to commercialization.

Lowering the threshold is an eternal topic in blockchain development.

Previously, when various Internet giants entered the cross-border blockchain field, they were willing to start with BaaS services.

BaaS services mainly focus on providing developers with a complete set of development tools to lower the threshold for developers to build their own alliance chain system.

How is the "open alliance chain" that emphasizes further lowering the entry threshold realized?

The biggest difference between "open alliance chain" and BaaS services is that developers can use the blockchain without purchasing servers or building nodes.

Specifically, small and medium-sized developers can directly access the blockchain and carry out on-chain business through the IDE, smart contract development templates, DApp development assistants, and other components provided by Ant Blockchain.

Jin Ge, general manager of the Ant Blockchain Platform Product Department, gave an example of traceability scenarios:

"Open Alliance Chain" is actually a product between a public chain and an industry alliance chain. But in terms of form, it is more inclined to the industry alliance chain.

There are also differences between "open alliance chains" and industry alliance chains. The customer levels and business models they cover are different.

In terms of customer level differences, industry alliance chains cover top customers, such as listed companies or leading companies similar in size to listed companies, which have greater influence in the industry. The "open alliance chain" covers small and medium-sized customers with small revenue and some developers.

In terms of business model differences, industry alliance chains are more connected in the form of projects, with long implementation cycles and project volumes exceeding one million. "Open Alliance Chain" emphasizes a ready-to-use, on-demand pricing model with a low threshold.

At the press conference, Jin Ge also made a detailed analysis of the five major capabilities of the "open alliance chain":

Overall, the "open alliance chain" Currently we are adopting a low-cost, low-threshold pricing service model.

From the official website, it can be seen that the open alliance chain provides users with two versions: professional version and enterprise version. The product has three pricings, each priced at 100 yuan/month (professional version, for test-type novice developers) , 999 yuan/year (professional version, for developers who really need to access the blockchain), 4888 yuan/year (enterprise version, for enterprise-level developers with relatively high-frequency transactions).

The enterprise version is suitable for high-frequency scenarios such as games, social networking, bills and people's livelihood, and public welfare, while the professional version is suitable for low-frequency scenarios such as copyright contracts, organizations, and traceability.

Both the professional version and the enterprise version can enjoy the basic services provided by the open alliance chain. Apart from the price, the biggest difference between the two is the user rights of the professional version.The TPS ≤ 10, the monthly available fuel is 1 billion; the enterprise version user rights can use TPS ≤ 100, the monthly available fuel is 100 billion. In addition, the first 100 enterprise version users can also obtain the creation product status of the "open alliance chain".

In addition to lowering the threshold, large companies are always willing to create scenarios when it comes to blockchain. The evolution from BaaS to "open alliance chain" is also a manifestation of giants attracting more developers by lowering the threshold to feed back application scenarios.

According to reports, the current main application scenarios on the open alliance chain are mainly 2C services, involving game interaction, public welfare traceability, copyright, bills and people's livelihood, etc.

It is easier for customers with their own scenarios to form a relatively stable group.

The follow-up plan of "Open Alliance Chain" is also closely related to the implementation of blockchain scenarios.

Jin Ge also introduced three future plans for "Open Alliance Chain":

1. Create more valuable industry scenarios based on existing customers, and hope In the future, we can expand more blockchain service providers in small and medium-sized enterprise industries, such as education, retail, agriculture, medical care, cultural tourism and other industries, and contribute more scenarios;

2. The Ant Industry Alliance Chain Provide it to customers on an on-demand pricing basis;

3. Gradually add more industry alliance chain technologies, such as digital identity, cross-chain, and cloud integration capabilities, to the open alliance chain according to the market pace Go inside to further lower the development threshold for developers and solve technical problems.

㈥ In the blockchain, what is cross-chain

Cross-chain: As the name suggests, it is a technology that allows value to cross the barriers between chains. direct circulation. Compared with the traditional Internet field, cross-chain only requires the circulation of information, but the cross-chain of blockchain is not a simple information transfer. It requires the transfer of value from one chain to another, and the value must circulate freely. First, problems such as double payments need to be solved, otherwise value chaos will occur.
The blockchain is a decentralized network, with one blockchain and one ledger. There is no correlation between the ledgers between different chains. The circulation of assets is on their respective chains, and accounting is done after cross-chain Interoperability with settlement is a difficult problem.

If it is a isomorphic chain, it is okay. The consensus algorithm, block generation and verification rules, transaction broadcast, security mechanism and other logic of both parties are consistent, so cross-chain interaction is relatively simple. Heterogeneous chains have different consensus mechanisms and accounting methods. Reaching a secure consensus is a technical difficulty. Therefore, cross-chain is a technical activity and a challenge for many developers.
The current cross-chain solutions mainly include Notary schemes, Sidechains/relays, and hashes.Locking (Hash-locking), distributed private key control (Distributed private key control), etc.

Among the existing blockchain cross-chain projects, projects based on the side chain/relay model account for the highest proportion. Since the hash lock-based Lightning Network was launched on the main network, the number of nodes and channels have increased. The number and network capacity continue to grow, and the feasibility of the technology has been well verified. However, existing cross-chain technology solutions still have certain flaws in different aspects, and there is still a lot of room for improvement in the future. On the one hand, the technical issues faced by cross-chains are somewhat complex; on the other hand, blockchain technology is developing rapidly, and the types and technical complexity of blockchains are also constantly increasing, leading to requirements for cross-chain technology changes. is constantly improving. Cross-chain has far-reaching significance for whether the blockchain can eventually form a value Internet, or even whether it can far exceed the value scale of the Internet.

㈦ What does blockchain mean and what are its applications in cross-border payments

Why is it said that the Internet era is coming to an end and the blockchain era is coming?

Once the blockchain develops, more innovations will burst out. Since the birth of Bitcoin, the first product of the blockchain, many innovations have been born. For example, small-amount cross-border payments, recording transfers between currencies, recording various stocks, registering house property rights, recording program codes, etc.

The steam age liberated social productivity, the electrical age revitalized social collaboration capabilities, and the Internet The era has connected the world together, and the blockchain era will allow us to truly achieve freedom.

㈧ What is the cross-chain technology of blockchain?

Blockchain is a type of distributed ledger technology. Each blockchain is equivalent to an independent ledger. Usually In this case, it is impossible to transfer value between different ledgers. With the development of technology and market, there are more and more types of cryptocurrencies, and at the same time, a large number of different blockchains have emerged. Collaboration between different chains has become a new need for users in terms of operation and value circulation, so the "cross-chain technology" of blockchain emerged as the times require.
The so-called "cross-chain" means that assets originally stored on a specific blockchain can be converted into assets on another chain, thereby realizing the circulation of value. It can also be understood as an exchange behavior between different asset holders. This process does not actually change the total value on each blockchain. Just like the currency transactions provided by the trading platform, different types of digital currencies can be traded.The exchange is performed, but this behavior of the trading platform does not occur on the blockchain.
Technically, blockchain is a distributed ledger, but from a commercial perspective, it is essentially a value network. The isolation between different blockchains not only results in the inability of digital assets to be included in the blockchain The circulation between chains also limits its value to a narrow range, which limits its own development space to a certain extent.
Therefore, more and more people are paying attention to cross-chain technology. In September 2017, Litecoin founder Li Qiwei stated on Twitter that Litecoin and Bitcoin had achieved atomic-level cross-chain exchange; in November, the Lightning Network Laboratory completed the first Lightning Network transaction from Bitcoin to Litecoin. Cross-chain transactions.

㈨ Ant Group has released another blockbuster blockchain application. Can it create another "Alipay"?

Prior to this, Alibaba has repeatedly predicted that it will release a "subversive" application today. product". So, what pain points can Trusple solve? What are the application prospects? What difficulties and obstacles does the promotion of Trusple currently face?

Another “Alipay”

“Same as Alipay’s original intention of launching secured transactions, Trusple also aims to solve the problem of transaction trust. The difference is that since blockchain technology is solving With outstanding features in trust in complex processes, Trusple better meets the needs of solving trust in international trade." said Jiang Guofei, Vice President of Ant Group and President of the Intelligent Technology Business Group.

Specifically, on the Trusple platform, when a buyer and seller generate a trade order, it is automatically uploaded to the chain and begins to circulate. The bank will automatically pay based on the payment terms agreed upon in the order, avoiding the traditional model. Sellers need to urge buyers to transfer money offline, and at the same time, they can also prevent the frequent malicious delay in payment time. Buyers can also obtain financial services such as account terms based on real orders on the chain, which greatly improves capital utilization and procurement efficiency.

For buyers and sellers, every successful transaction on Trusple is a deposit of "on-chain credit". When a company has financing needs, financial institutions can submit a verification request to the Trusple platform to determine the authenticity of the company's trade. In this way, on the one hand, it reduces the financial service risks of banks and other financial institutions, and at the same time, it also revitalizes the survival and operating capabilities of small and medium-sized enterprises.

It is understood that five banks, including BNP Paribas, Citibank, DBS Bank, Deutsche Bank and Standard Chartered Bank, have become Trusple’s first partners.

How complex is traditional trade finance business? The following is the bank's letter of credit business flow chart:

As can be seen from the above, the traditional international trade financing model is not only complex in process, but also requires high service fees from banks. If there is a blockchain trade settlement platform and a trade settlement contract is developed, the exporter can directlyPut the advance payment in the smart contract and wait for the exporter's goods to arrive at the destination. After the system verifies that the documents are qualified, the smart contract is triggered to release the money to the exporter. Not only is the process simple and the service fee is low, but more importantly, it can reduce the capital occupation cycle. , improve capital efficiency.

"This is the case with Trusple currently launched by Ant Group, and Ant Chain also supports smart contracts." Li Lianxuan said.

To sum up, the difference between traditional cross-border trade and Trusple is centralization and decentralization. In the traditional trade model, banks serve as the center, providing transaction credit or financing facilities to buyers and sellers to ensure the smooth progress of transactions. The "credit" in this is the bank's third-party credit. As for the trust model of blockchain, its "credit" comes from the blockchain itself and does not require a third-party intermediary.

Facing two major obstacles

The launch of Trusple also fulfilled a long-cherished wish of Ali for 19 years.

As early as 2001, Alibaba B2B Company tried to use a model similar to an intermediary guarantee to solve the problem of mutual distrust between buyers and sellers in foreign trade transactions, but was unable to do so due to technical constraints at the time. Two years later, the emergence of Alipay solved the trust problem among C2C business users. However, because transactions between enterprises are much more complex than between individuals, and payment methods and logistics methods are also very different, the plan 19 years ago has been shelved to this day. Until the emergence of blockchain provides new solutions. For this reason, Alibaba calls the launch of Trusple a major launch comparable to the birth of Alipay.

It is worth noting that although Trusple has similar functions to Alipay, both are designed to solve the trust problem between different subjects, but the solution ideas are completely opposite. Trusple aims to eliminate middle links and disintermediate, while Alipay is the largest intermediary with 1 billion users. Trusple only targets B-side users in cross-border trade, so it seems to be fine with Alipay for now. So if similar products are used in domestic C2C e-commerce scenarios in the future, it will revolutionize Alipay's life.

Alibaba’s blockchain layout

Blockchain is based on the characteristics of decentralization, openness and transparency, information traceability, anti-tampering, automatic execution of smart contracts, etc., and is a natural solution to trust issues. weapon. As The Economist said: Blockchain will become a “trust machine.” Therefore, Jack Ma said that Alibaba without blockchain would "die".

Jack Ma’s words are not alarmist. Alipay, which started as an e-commerce company, has played a key role in solving the trust issue between consumers and merchants in online transactions. It can be said that without Alipay, Alibaba would not have the e-commerce empire it has today. “Over the past decade or so, we have continued to promote the construction of trust mechanisms through technology and innovation,” Ant Group said in its IPO prospectus.

For this reason, as early as 2015, Ali becameA blockchain team was established and began to invest in blockchain research and development. In October 2017, Ant Financial (the predecessor of Ant Group) released the "BASIC Strategy" (blockchain, artificial intelligence, security, Internet of Things, cloud computing). In July this year, just before Ant Group applied for listing on the Science and Technology Innovation Board, Ant Blockchain was officially upgraded to "Ant Chain". Jack Ma personally named Ant Chain, which shows its status in the Alibaba ecosystem.

Today, Alibaba has implemented more than 50 blockchain application scenarios. Ant Chain is technically able to support 1 billion account sizes and can support 1 billion daily transactions, achieving 10 transactions per second. Wanbi cross-chain information processing capabilities (PPS).

In April this year, Ant’s “Open Alliance Chain” was officially launched, fully opening up its blockchain technology and application capabilities to small and medium-sized enterprises. Subsequently, the implementation of related blockchain applications further accelerated. In July, the Ant Chain all-in-one machine was released, which can save more than 90% of blockchain deployment time for government and enterprise developers; on September 18, it was opened to the public including data security computing hardware, The privacy and security "three-piece set" of 3D contract security services and data privacy computing services; Trusple is released today.

In terms of research and development, Alibaba’s blockchain patent applications have ranked first in the world for four consecutive years, and its self-developed cross-chain technology has also been recognized as an international standard.

According to the website of the Shanghai Stock Exchange, Ant Group’s Science and Technology Innovation Board IPO has entered the “submission for registration” stage. "After listing, the most important thing for Ant Group is to invest in technology. In the future, it will focus on investing in the five major technical fields of artificial intelligence, risk management, security, blockchain, computing and technical infrastructure." Ant Group CEO Hu Xiaoming said.
