Project address: Enterprise M&A and Financing Information Service Platform_Tamigo
2. Application Case 2: Xuyuan Art Digital Asset Trading Service Platform is a trading platform for art copyrights and a discovery platform for global art values. A truly decentralized high-end service platform for the international art market. Based on the blockchain token, the platform implements an encrypted digital currency based on the world's outstanding artworks to exchange the value of artworks. Functions include copyright certification: artists and creators can perform copyright certification on the platform. Asset tokenization: Art creators divide the artistic copyright into tokens, and investors invest according to their subscription shares and receive income. Usage rights trading: Artists and creators place the rights to use artworks on the chain for transactions, and trigger smart contracts, allowing buyers to obtain the rights to use artworks (including various transactions such as leasing, exhibitions, etc.).

② Epic blockchain project: VDS

As a blockchain project, VDS is an integration of multiple research results on a distributed privacy Internet based on blockchain. It will play an important role in identity security, Internet freedom, private social networking, decentralized finance and commerce. It can be said that what VDS does is to rebuild a completely new network on distributed anonymous nodes.The open Internet will lead us to an unprecedented free space, V-Dimension (five-dimensional space).

The initial functions of VDS are resonance trading, trust stamp network, competition system, information network broadcast (VAD), secret chat, anonymous transactions, smart contracts, distributed OTC transactions, super master nodes, lucky draws And unique smart contract design - chain merchant contract. All these functions echo, circulate and balance each other, forming a strong internal structure of VDS in the early stage. Its inherent financial balance, community promotion, business docking, value precipitation and network expansion will subvert the concept behind the centralized business model.

VDS will become a private Internet network for use by the world. It supports the development of independent web browsers, and each VID address can be used as an anonymous IP address. In this open privacy network, all applications of the centralized Internet can be transplanted, and through the joint efforts of the community, a new, decentralized Internet free ecology can be created.

The core concept of VDS is to rely on the wisdom of all people to achieve freedom for the entire human society, and is committed to providing more fair, equal and private wealth autonomy for each of us and even every generation. It will achieve the ultimate wealth freedom for all mankind.

At the same time, VDS will achieve complete freedom of speech. Through unique anonymous technology, anyone can express opinions and convey ideas through private chats on a decentralized network, and communicate safely and freely. Or the advertising content can be inserted into each VDS user's wallet application through the bidding advertising broadcast system to achieve broadcast across the entire network. Information and its dissemination will break through the limitations of centralized supervision, and people will truly understand the world.

The freedom of innovation brought by VDS is a business innovation model that breaks regional restrictions. Wherever there are people, there is a network, and wherever there is a network, there is a VDS. Anyone can develop his or her business empire to every corner of the world through VDS's unique smart contract technology.

In any trading market, the cash flow flowing into the market is directly related to the number of participating users. Therefore, all our users participate in the decentralized fission promotion, and while personally gaining benefits, they also provide a large number of users to the system. This is a benign cash flow benign solution. As the price of Vollar increases, users will more actively participate in fission expansion, doubling the number of users in the VDS ecological network.

In addition, a large amount of Bitcoin will be used as a reward for the fission promotion of each block week to encourage more users to participate in the construction of the VDS ecological network. The amount of Bitcoin rewards depends entirely on the number of Bitcoins involved in Resonance Transactions. The more benefits Vollar brings, the more people who participate in resonance trading willThe more Bitcoin there is, the greater the incentive for new user growth.

In the VDS ecosystem, the creation of super master nodes will bring considerable Vollar benefits to participants. As the income from Vollar increases, more and more participants will gradually understand its value, thereby creating more super master nodes to obtain more Vollar.

The increase of super master nodes provides more stable network services for the VDS ecosystem. In addition, a deposit of 10,000 Vollar is required to build a super master node. Therefore, more super master nodes means more Vollar will be used as deposits, which helps to greatly reduce the number of Vollar that can be traded on the market and stimulate its price growth.

In addition, the exponential growth of users within the VDS ecosystem has also accelerated the purchase demand for Vollar, thereby doubling the market demand for Vollar and further reducing the total tradable volume in the current period, forming a virtuous cycle of value and A sustained and steady rise.

As the value of Vollar continues to rise, a large number of users will continue to participate in the expansion of the VDS ecological network. In order to increase user stickiness, we have added more meaningful functions to the ecosystem: for example, the world's most secure social chat application, a network-wide advertising broadcast system that accurately connects target users, chain merchant functions that connect business value, and Securely connect to the OTC function of 50 legal currencies around the world. Through these functions and applications, the use value of Vollar will be highlighted when people experience the VDS ecosystem, which lays the foundation for Vollar to become a universal currency in the future.

Driven by Vollar’s ​​revenue and the joint efforts of a large number of participants, the VDS ecological network will rapidly develop and mature, and the mature VDS ecology will surely accompany all participants to the ultimate freedom.

Vollar is the name of the basic circulation unit in the VDS ecosystem and its only commercial and financial delivery medium. In addition to being used for account records and payments, Vollar can also activate VID, bid for VAD advertising spaces, incentivize the operation of master nodes (to ensure the stability of the network), and run smart contracts within the system.

VID is the identity indicator of the VDS community, and it is the only identity certificate with passability in VDS. It is like a key that users use to unlock various features and applications, such as trust-stamped networks and private chats. To a large extent, only with VID can you truly experience the powerful free network-VDS.

VAD is a decentralized advertising bidding broadcast system. The advertisement with the highest bid is selected for dissemination among nodes, and then the information is inserted into each VDS wallet to create accurate and effective commercial connections and improve Vollar's ability to serve as a circulating currency. We call this network-wide broadcast.

Produced by trust-stamp network fission promotionWith a huge user base, VAD will become a super radio station in the global advertising industry. The chain merchant contract is a unique smart contract system in VDS. Suppliers around the world can register payment addresses on the VDS chain, set smart contract commission rates, and activate chain merchant contracts. Through these smart contracts, merchants register their payment addresses under their trust stamp system, set the contract commission distribution ratio, and create their own blockchain consensus sales network in one step.

If all VID users in the trust stamp network make purchases at merchants that activate the chain merchant contract, then the 12 directly connected VIDs upward in the VID fission tree can obtain the merchant's chain merchant contract commission.

VID activation code:

In the actual application of the VDS chain merchant contract, various sales promotions can be carried out, which is a perfect integration of blockchain technology and daily life. Consumers can completely use Vollar and complete consumer spending through chain merchant contracts. Whether it's fast food or medical bills, we can create unique chain merchant contracts to complete a series of related payments. Similarly, suppliers can also acquire a large number of consumers through the bidding advertising function of VDS, provide customers with more convenient services and experiences, and quickly promote through the trust stamp network through simple commission settings. After combining with other VDS functions, anyone can simply integrate their existing resources to complete consumption or sales.

Virtual products are also possible. Consumers can purchase and sell coupons and game props directly within VDS through chain merchant contracts. Regardless of the amount of consumption, every expenditure will be carried out accurately in accordance with the contract provisions; the supply and demand relationship and promotion methods are particularly clear. We will complete the circulation of funds in various categories in a more efficient, flexible and convenient way.

Large shopping platforms can further develop and apply VDS chain merchant contracts and integrate them into the payment system of the shopping platform. When a new user completes registration, the corresponding chain merchant contract payment address will be generated. Compared with traditional shopping platforms, this is a highly disruptive blockchain industry practice because it transforms every new user into a marketing promotion force.

Based on the VDS smart contract, the chain merchant contract forms a decentralized business model for value sharing by implanting each VID and the interpersonal relationships under its trust stamp system. Any merchant can set commission allocation settings for smart contracts in a decentralized manner, relying on the trust relationship established within the blockchain to mobilize the promotion enthusiasm of each VID. VIDs share the sales commissions obtained from the goods or services, helping merchants obtain a steady flow of customers and promote the sales of goods or services. High-quality products will receive greater promotion efforts and increase product sales, which will also subvert the existing centralized business thinking. Each VID will establish its own business ecosystem through VDS and use decentralized thinking to redraw the blueprint of the global business empire.

③ Operation of blockchainPrinciples and development, you have to know!

1. Why is there innovation in blockchain?
The starting point of the first generation of the Internet is the TCP/IP protocol, which implements a unified format for peer-to-peer transmission of information by all nodes on the network. Open code. However, the impact of such an uncomplicated innovation on mankind is epoch-making. It has programmed, agreed, and enforced the basic values ​​required by a unified global market: "freedom, equality, and fraternity." Then the STMP email protocol, HTTP domain name protocol, etc. were derived, achieving low-cost and high-efficiency global information transmission in a decentralized manner. As Alibaba Vice President Gao Hongbing said:
"The Internet is to eliminate the (information) supply chain that has very low value and high cost - it is open, interconnected, peer-to-peer, globalized, and decentralized."
We know: The essence of the market is also decentralized. It automatically executes the decentralized agreement of "equivalent exchange". Just as Nobel Prize winner Ronald Coase summed up: "The market economy is based on two On the basis of deep cognition: admitting ignorance and tolerating uncertainty." Adam Smith also described the market as: "the invisible hand"! Therefore, the market must require the low-cost flow of information decentralization, and the Internet has adapted to the global Under the general climate formed by the unified market, it turned out to be.
However, the first generation of Internet decentralized solved the problem of low-cost and efficient transmission of information, but it did not solve the problem of credit of information. Therefore, what the second-generation Internet must break through is: how to establish global credit in a decentralized manner so that value transfer can be carried out at low cost and with high efficiency.
So what are the problems with the original centralized credit system? As we all know: centralized credit, such as the legal currencies of various countries, has different credit values, and the clearing systems are also incompatible, which adds a lot of cost to global trade. The current global credit system centered on the US dollar has a "Triffin Paradox" in its mechanism (the essence is that a country's legal currency cannot simultaneously resolve the conflict between its own economic interests and global economic needs). Therefore, in 2009, the Governor of the Central Bank of China, Zhou Ogawa called for the creation of a super-sovereign storage currency. In the same year, Satoshi Nakamoto disclosed the first-generation blockchain source code-"Bitcoin" online.
2. How does the blockchain system operate?
First of all, Satoshi Nakamoto knew very well that establishing a credit system for payment must solve the problem of preventing "duplicate payments", that is, no counterfeit currency can be created. The centralized credit system relies on state machinery to prevent counterfeit currency. What about "Bitcoin"? Satoshi Nakamoto's great innovation is to "timestamp" every transaction. There is a block (block: equivalent to a network account book) every ten minutes, and all network transactions for these ten minutes are correctly timestamped. The question is who will cover it? Satoshi Nakamoto did not assume that everyone on the Internet is Lei Feng. He agreed with Adam Smith: people in the market are greedy. He asked the so-called "miners" to compete for the accounting rights of each ten-minute block. The rules of the competition were to keep the accounting correctly and at the same time solve the SHA256 problem.Whoever can prove that their computer has the fastest computing power (the so-called PROOF OF WORK mechanism) can compete for the legal accounting rights of these ten-minute blocks and receive a reward of twenty-five Bitcoins. This is the so-called "mining" process. It is actually a decentralized credit process that establishes a network-wide ledger - the blockchain. Therefore, the more essential function of miners is "bookkeepers"!
Satoshi Nakamoto is here In its Bitcoin white paper, the process of establishing this credit system is described in detail:
Step 1: In order for the entire network to recognize it as valid, each transaction must be broadcast to each node (node: that is, the miner);
The second step: Each miner node must correctly timestamp each transaction in these ten minutes and record it in that block;
The third step: Each miner node must Compete for the legal accounting rights of this ten-minute block by solving the SHA256 puzzle, and strive to get a reward of twenty-five bitcoins (fifty bitcoins every ten minutes for the first four years, decreasing by half every four years);< br>Step 4: If a miner node solves the SHA256 puzzle of these ten minutes, it will publish all the timestamped transactions recorded in its ten-minute blocks to the entire network, and they will be checked by other miner nodes in the entire network;< br>Step 5: Other miner nodes in the entire network check the correctness of the block accounting (because they are also stamping the accounting at the same time, but they have not competed for the legal block accounting rights, so there is no reward), there is no error Finally, they will compete for the next block after the legal block, thus forming a single chain of legal accounting blocks, which is the general ledger of the Bitcoin payment system - the blockchain.
Generally speaking, each transaction must undergo six block confirmations, that is, six ten-minute accounting, before it can finally be recognized as a legal transaction on the blockchain. The following is the accounting format of Bitcoin:
So the so-called "Bitcoin" is such a billing system: it includes the owner electronically signing with the private key and paying to the next owner, and then the entire network's "miners" "Time stamp the account and form a blockchain.
3. What are the innovations in Bitcoin’s blockchain finance?
Similar to gold, trying to establish decentralized credit on the global Internet may allow value to flow across the entire network at high speed and at low rates (currently each transfer The transfer rate is one ten thousandth);
The total amount of currency is agreed upon by the cryptographic protocol;
Compared to gold, digital currency is infinitely divisible;
The value of currency can be based on a large number of P2P transactions ;
Full transparency in financial management (every transaction can be traced on the blockchain).
Bitcoin’s blockchain-wide accounting system has established a market value of US$10 billion, the highest on the global Internet. Therefore, Wu Xiaoling, dean of Tsinghua PBC School of Finance, pointed out: The blockchain experiment established distributed credit, which is an upgraded version of Internet TCP/IP, upgrading from information transmission to value transmission;
4. Bitcoin’s blocks What are the inherent flaws of the blockchain system?
Bitcoin’s blockchain system has been on the Internet since 2009Since the open source operation on the Internet, there have been some successes, but it has also shown some inherent flaws that are difficult to overcome:
The total amount cannot change with the market situation, and will inevitably rise and fall; Only 1% of the miners can compete for the accounting rights of less than ten minutes of blocks, and more than 99% of the other miners participating in the competition waste their computing power;
Inflation of about 10% every year has greatly increased the cost of the Bitcoin financial ecosystem. , even threatening her survival;
As a decentralized self-organizing DAC system, the operating costs of the accounting and issuance functions are too high.
As a global payment system, its efficiency is far from meeting the actual requirements of global trade. The Bitcoin network currently confirms a maximum of 7 transactions per second. In comparison, Visa's network system can process 10,000 transactions per second at the fastest, and Alipay's record is 80,000 transactions per second on Singles' Day in 2014!
5. Block The development of chain technology 2.0:
As the 2.0 upgrade and development of blockchain, it first focuses on solving the high-carbon mining of Bitcoin accounting:
When we discuss how to overcome the high carbon of Bitcoin mining and accounting Professor Liu Taoxiong from the Tsinghua Institute of Economics pointed out that mining competition relies on computing power. In the end, only one company competes for the legal accounting rights, and the other 99% of the miner nodes are mined for nothing, which is a waste of resources. It is obviously unreasonable. If The whole network transparently knows the legal accounting rights of the next block, and it is randomly generated in the entire network, which eliminates the high carbon cost of competitive accounting! After hearing this, we all praised Professor Liu for his brilliant idea, because the second generation is now more successful. Coin NXT has this mechanism. Their white paper is called "Transparent Forging". However, the probability of the accounting rights going to someone is directly proportional to the NXT token holdings in each miner node wallet. This is called the proof of equity mechanism ( PROOF OF STOCK). Of course, this also triggered a debate about the unfairness of NXT’s distribution of tokens to early investment developers!
RIPPLE is a semi-decentralized blockchain solution that uses “trusted gateways” to conduct block operations. The credibility of chain accounting is based on the consensus ledger protocol that these gateways will not do evil at the same time.
The most ambitious attempt is Ethereum, which combines blockchain technology with Turing completeness, hoping to develop a basic platform that can support the construction of various blockchain systems in the future. The development of various credit currencies, digital assets, smart protocols and even financial derivatives. The system design is to unify blockchain accounting on the ETHERUM platform and be used by all developers. Maybe their official version will be released in the near future.
6. Possible applications of blockchain innovation in other fields:
Now, blockchain’s attempts to establish decentralized credit are no longer limited to the financial world, but have attracted attention from all fields of society, especially in At present, some of China's central credits, such as the "Red Cross", are in a "collapse" situation. Blockchain can provide a brand-new method for social management.ideas and technical options, here are some new developments and related discussions we have learned about:
The combination of blockchain and the Internet of Things unifies digital assets and atomic assets, smooths the difference between consumer assets and cash assets, and expands the public’s Credit, accelerate value circulation; (IBM-Samsung)
Establish an intellectual property protection system on the blockchain, keep accounts of the use of intellectual property across the entire network, and establish a global advertising market;
Can the blockchain contribute to the Belt and Road Initiative? Emerging economies issue protocol-based cryptographic currencies to provide technical support;
Blockchain + cloud computing can develop into decentralized self-media and community systems;
Blockchain can build a decentralized equity public Financing system allows innovative projects to enter the circulation field in advance;
Blockchain can develop a fully transparent financial management system;
Blockchain supports the establishment of a global decentralized corporate organization.
In short, in this era when credit has become a scarce resource, the technological innovation of blockchain, as a distributed credit model, provides new opportunities for finance, social management, talent evaluation and decentralized organization construction in the global market. All provide a broad development prospect.

④ The most straightforward explanation of blockchain

In recent years, the term "blockchain" has become a hot topic, and news media have been reporting on it, but you may The understanding of blockchain is still in the foggy stage. Today we will unveil its mystery.

In fact, the essence of blockchain is very simple and can be explained in one sentence: decentralized distributed database.

The main function of the blockchain is to store information. Anyone can write information and read it at the same time, so it is a public database.

Characteristics of blockchain

Distributed database technology has long existed in the market, but the difference is that although blockchain is also a distributed database , but it has no administrator and is completely decentralized.

Decentralization is a disruptive feature of blockchain technology. It does not require a centralized agent and realizes a direct point-to-point interaction, enabling high-efficiency, large-scale, and information interaction without a centralized agent. way becomes reality.

However, without an administrator, everyone can write data into it. How can we ensure that the data is trustworthy? What should I do if I am changed by a bad person? The designers have already thought of this, which proves that blockchain is a truly epoch-making product.

Block

The blockchain is composed of blocks. Blocks are much like database records. Every time data is written, a block is created.

Each block contains two parts:

Block header (Head): records the characteristic value of the current block
Block body (Body): actual Data
The block header contains multiple characteristics of the current block.value.

Generation time
Hash of the actual data (i.e. block body)
Hash of the previous block
...
Every time in the system Each node has the latest complete database copy. Modifying the database of a single node is invalid because the system will automatically compare and consider the same data record that appears the most times to be true. At the same time, every step of the data record will be retained on the blockchain, and the information at each step can be traced.

Here, you need to understand what a hash is, which is necessary to understand the blockchain.

The so-called "hash" means that the computer can calculate a characteristic value of the same length for any content. The hash length of the blockchain is 256 bits, which means that no matter what the original content is, a 256-bit binary number will be calculated in the end. And it can be guaranteed that as long as the original content is different, the corresponding hash must be different.

For example, the hash of the string 123 is (hexadecimal), which is 256 bits when converted to binary, and only 123 can get this hash. (Theoretically, it is possible for other strings to get this hash, but the probability is extremely low and can be approximately considered impossible.)

Therefore, there are two important inferences.

Corollary 1: The hash of each block is different, and the block can be identified by the hash.
Corollary 2: If the content of the block changes, its hash will definitely change.

The immutability of hashes

Blocks and hashes have a one-to-one correspondence, and the hash of each block is for the "block header" (Head) computational. That is to say, the characteristic values ​​​​of the block header are connected together in order to form a very long string, and then the hash is calculated on this string.

Hash = SHA256 (block header)

The above is the calculation formula of block hash. SHA256 is the hash algorithm of the blockchain. Note that this formula only includes the block header and not the block body. In other words, the hash is uniquely determined by the block header.

As mentioned earlier, the block header contains a lot of content, including the hash of the current block body and the hash of the previous block. This means that if the content of the current block body changes, or the hash of the previous block changes, it will definitely cause the hash of the current block to change.

This is of great significance to the blockchain. If someone modifies a block, the hash of the block changes. In order for subsequent blocks to still be connected to it (because the next block contains the hash of the previous block), the person must modify all subsequent blocks in sequence, otherwise the modified block will be removed from the blockchain . For the reasons mentioned later, haXi's calculation is very time-consuming, and it is almost impossible to modify multiple blocks in a short period of time, unless someone controls more than 51% of the computing power of the entire network.

It is through this linkage mechanism that the blockchain ensures its own reliability. Once the data is written, it cannot be tampered with. This is just like history, what happened happened, and it can’t be changed from now on.

⑤ How to set private privacy in Jack Ma's blockchain

As a decentralized database technology, the private privacy setting of blockchain is a very important part. Jack Ma may set up the following aspects of privacy protection on his own blockchain:
1. Identity verification: On Jack Ma’s blockchain, individual users can protect their privacy through identity verification. This means that only authenticated users can access specific information.
2. Encrypted data: Jack Ma can use blockchain technology to encrypt personal data to prevent unauthorized access. This encryption technology protects user privacy by ensuring that only authorized users can access data.
3. Anonymous transactions: An anonymous transaction function can be set up on Jack Ma’s blockchain, allowing users to conduct transactions without exposing their identities. This approach can protect user privacy to the greatest extent.
4. Restrict access rights: Jack Ma can set access limits on the blockchain to only allow specific users or organizations to access specific information. This approach protects user privacy by ensuring that only authorized people have access to sensitive information.
In short, Jack Ma can protect his blockchain privacy through various means such as identity or verification, encrypted data, anonymous transactions and restricted access rights. These measures ensure that users’ data and privacy are protected to the greatest extent possible.

⑥ How does NetEase’s games detect plug-in scripts?

The detection is as follows:

NetEase (Hangzhou) Network Co., Ltd. disclosed the patent "plug-in detection method and device" , node equipment, game servers and media”. According to Qichacha’s content, the patent was published on February 19, and the current simple legal status is “under review.”

The data shows that NetEase Games uses the first blockchain to detect whether the players to be detected use plug-ins based on the game operation behavior information sent by the game server, and stores the plug-in usage information of the players to be detected through the second blockchain. The punishment results will be recorded in the second blockchain to ensure the fairness and transparency of the punishment of the anti-cheating system in the game.

The method involved includes: receiving the game operation behavior information of the player to be detected sent by the game server; performing cheat detection on the player to be detected based on the game operation behavior information to obtain the cheat detection result.

If the player to be detected uses a cheat, send the cheat usage information to the second blockchain, so that the game server obtains the cheat usage information from the second blockchain, and performs punishment operations on the player to be detected based on the cheat usage information. , and record the penalty results in theon the second blockchain.

Introduction:

NetEase (NASDAQ: NTES) was founded in Guangzhou in 1997 by founder and CEO Mr. Ding Lei. It was listed on NASDAQ in the United States in 2000 Listed on the exchange, it is China's leading Internet technology company.

We have always maintained a leading position in the Chinese industry in the development of Internet applications, services and other technologies. With a strong sense of mission for China's Internet development and the vision of creating a better life, NetEase uses the most advanced Internet technology to strengthen the exchange and sharing of information between people.

⑦ What model is blockchain?

Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms. Blockchain (Blockchain) is an important concept of Bitcoin. It is essentially a decentralized database. As the underlying technology of Bitcoin, it is a series of data blocks generated using cryptographic methods. , each data block contains a batch of Bitcoin network transaction information, which is used to verify the validity of its information (anti-counterfeiting) and generate the next block.

The biggest problem if such technology is to be put into application is the "impossible triangle problem"

That is, it cannot achieve scalability (Scalability) and decentralization () at the same time. , Security (Security), you can only get two of the three.

Most of the public chain projects currently on the market are difficult to put into use on a large scale.

If there is a public chain project that can solve this problem, it will be a revolution in the blockchain.

Backed by the world’s first and largest encrypted digital currency payment platform and wallet solution with a user base of more than 3 million, Velas (Virtual Expanding Learning, virtual expansion autonomous learning system) is a Artificial intelligence (AI)-optimized neural networks enhance its consensus algorithm, self-learning and self-optimizing public chains, and are committed to improving the security, interoperability, and high scalability of the transfer process and smart contracts. Velas uses AI-enhanced DPoS consensus to achieve complete decentralization without reducing security and transaction speed.

Velas has recently launched the Velas desktop wallet and web wallet

Velas web wallet

Velas web wallet allows users to process transactions within their web browser Cryptocurrency, purchase Velas token VLX, and support easy viewing of detailed history of all wallet transactions. Login credentials have an additional layer of security with two-factor authentication feature.

In addition to the basic functions of creating and restoring wallets based on mnemonic strings, all data stored in the Velas web wallet uses RSA-256-CBC algorithm is used for encryption to ensure that user data is not stolen or misappropriated by the system owner or external attackers.

A prominent feature of the web version of the wallet is that it supports exchanging VLX tokens for other cryptocurrencies within the wallet, and the wallet will continuously refresh the current VLX exchange rates for all fiat currencies for users’ reference.

Velas Desktop Wallet

Velas Desktop Wallet is a highly secure wallet program suitable for Windows, macOS, and Linux operating systems. The desktop wallet also uses the same mnemonic features and RSA-256-CBC encryption algorithm as the web wallet.

Unlike the web version, which is an online wallet, the Velas desktop wallet allows users to store their wallets directly on their computers, avoiding potential risks of online attacks, including phishing, IP fraud and XSS. It is worth mentioning that both the desktop and web wallets provide users with an automatic lock option for security issues. If not used for a long time, they will need to enter a password when logging in again before they can access again.
