Through the products and services of the world platform, it provides enterprises with services for rapid deployment of efficient blockchain solutions, and at the same time realizes one-stop management of bitcoin, ether, various tokens and enterprises' own digital tokens, simple and convenient Complete the transaction and exchange of digital currency, and can bind digital assets with bank cards, realize the seamless connection between digital currency and the physical world, let your digital currency be used in various transaction consumption scenarios, and truly activate your digital assets.

wolrd is based on the world, and on the premise of complying with the current laws and policies of various countries, it connects with payment institutions and card issuers to provide users with compliant and safe products and services.

1. Multi-blockchain asset management

Through the world's wallet APP, it can provide users with unified management of multi-blockchain assets. It has the following characteristics:

• One-stop management

world unified management of multiple digital currencies through a wallet APP, not only supports the storage and management of mainstream assets such as Bitcoin and Ethereum, but also supports the standard protocols of smart contract platforms such as Ethereum and WORLD TOKEN, and rapidly increases the number of digital currencies issued based on each platform. Token. While reducing the burden of user management, it also provides wallet service support for new ICO/IPO projects, allowing the project team to focus more on core services.

• Decentralized service

WORLD upholds the core essence of the blockchain and provides users with a decentralized digital currency storage solution. Wallet keys and address private key information for all types of currencies are stored in the user's local system. At the same time, world provides a convenient key backup scheme-users only need to make a backup once, write down the mnemonic, and save it in a safe place. Even if the types of digital currency are subsequently added, all types of digital currency assets can be restored with the backup mnemonic words.

• Multiple security guarantees

In addition to allowing users to fully control the wallet keys, world also provides multi-signature technical guarantees and two-step authorization verification for digital asset management of different scales. Users can choose to perform verification methods such as mobile phone verification codes, fingerprints, and living bodies during transfer transactions. Fangwei guarantees the security of digital currency assets.

• Multi-language support

The World Wallet APP plan will support multiple languages ​​in mainstream digital currency markets such as Chinese, English, Japanese, and Korean, and clear language barriers for creating a world-class wallet application.

2. Digital currency exchange and transaction

The World Wallet APP provides users with simple, convenient and safe exchange and transaction services through the original WORLD TOKEN trading platform and docking exchange API.

• Risk-free currency exchange

The WORLD TOKEN trading platform realizes risk-free digital currency exchange services through smart contracts, cross-chain gateways and cross-smart contract technologies (see the description of technical features for specific details). Users use MAX to exchange digital currencies. Platform parties or other third parties create smart contracts for exchange. The contract mechanism monitors and executes the exchange process, avoiding the risk of default by all parties involved in the transaction. Compared with centralized platform services, smart contracts avoid the subjective risk of default or objective attacks on the platform and bring losses to users. Even for the tokens issued by new ICO projects, as long as the world wallet supports it, risk-free exchange transactions can be carried out through the wallet service. On World token, there are standard various digital asset exchange services, and various digital assets can be freely exchanged.

• Simple and convenient transaction

There are certain entry barriers and learning costs to buy and sell digital currencies through exchanges. world provides users with the best market price and simple operating experience through the docking exchange API-world through the optimized screening mechanism, presents users with simple buying and selling prices, and users only need to enter the quantity to be like Complete transactions as easily as on the e-commerce platform.

• Convenient deposit tools

World provides users with credit card consumption channels and mobile phone credit card readers through docking with payment service providers. When a user wants to buy 100 US dollars worth of Bitcoin, he only needs to initiate a purchase transaction in the world's wallet app, connect the app to the card reader, and use the US dollar bank card to complete the transaction. The World backend transfers 100 USD to the exchange account through the exchange API, and after the exchange completes the transaction of buying bitcoins, the bitcoins are transferred back to the user's wallet. The whole process is as simple as offline consumption by credit card.

3. World and World Token chain platform

On the world platform, generate the algorithm that provides the data or mining, and deposit the corresponding amount of world tokens, and publish them on the world platform together, so that there will be many world apps (mobile or PC) decentralized users The data mining program will be run to provide data or mining services for the digital asset, earning world tokens and corresponding digital assets. For example, the digital asset of a contract is to provide insurance services for crops, that is, when the rainfall index for several consecutive months is lower than a certain value, a certain digital asset is returned to the insurance user. In this case, the smart contract needs to know the daily rainfall index. If this index is provided by the official, there is a risk of official fraud and official attack, and the index data cannot be trusted. The official can configure the relevant functions in the smart contract, and at the same time announce the acquisition algorithm and deposit a certain world token on the Kcash platform. The world users on the platform find that running the program can earn good world tokens and the contract. They will provide decentralized data provision services for the digital asset. At the same time, the program can also have the function of mining. As long as the officially released program has this function, the user can also get a certain amount of the digital asset. After running for a period of time, users find that even if the official does not provide additional world tokens, since providing the data and mining services can obtain official digital assets, the income is good, and they will continue to provide services for the asset. For the official, you can simply pay some costs to get decentralized computing power, data and mining services; for users, you can earn good data and mining revenue, of course, users need to deposit some world in advance The security deposit promises not to provide false data. If the system finds that the user cheats, it will recover the user’s income and confiscate the user’s deposit. We call this form of mining contract mining. We all know that when the digital assets of some new projects are released, the depth of buying and selling is usually not enough. Then when users need to consume 1 dollar of digital assets, they need to spend additional digital assets. With our world platform For contract mining, the project party can provide an exchange mining program, that is, the mining user provides the exchange service between the project’s digital assets and the world token, so that when the user uses the project’s digital assets, the exchange service will Digital assets are converted into world tokens with sufficient depth for consumption, and at the same time, world tokens subsidized by the project party and miners' fees for corresponding digital assets for mining are obtained. With this type of service, even a newly launched project can complete the business logic for real-world consumption.

Of course, many projects need more than simple data services and mining services, they need their own blockchain to complete their own business logic. On wolrd, it is also very simple. The project only needs to configure the corresponding data in its own digital asset contract, such as the blockchain mode, block size, consensus mechanism, mining mode, etc., and store it in a certain world Tokens, then the miners of the world will find the demand. If the miners feel that the income is appropriate, they will switch some computing power to generate the side chain to support the blockchain of the project to earn world tokens and corresponding digital assets. If found to support If the digital asset is not cost-effective, the digital asset will be discarded. Under this logic, miners can always automatically configure their own computing power to obtain good returns. At the same time, when the computing power competition of a certain digital asset is too fierce or the mining machine owner finds that their mining machine has been calculated by the digital asset. When the power is eliminated, they will automatically exchange the computing power to some less competitive digital assets, so that the mining machine can be reused without being eliminated as garbage. For the project party, it can be as simple as depositing world tokens to obtain a decentralized chain and corresponding computing power support. When a side chain has a data failure or is completely dead, it will not affect the operation of the main chain at all, and the side chain has its own unique computing power. This side chain completely serves its own business logic, so there is no need to worry about network congestion. The problem. In this way, digital assets are completely separated from business logic, which solves performance problems and makes digital assets more secure. For example, if a major accident occurs when joining the main chain, because there are detailed data on the side chain, the user's digital assets can be restored; if a major accident occurs on the side chain, then only the business data is accidental, and the user's digital assets are not affected at all. , And the project party can restore the side chain by backing up the side chain data. In the world, generating and running a blockchain is so simple, efficient, and safe. The most important point is that it is simple to configure, and you can obtain powerful decentralized computing power. This is how you develop and run your own blockchain. Unmatched. Under this design framework, if one day the performance of the side chain is insufficient and the blockchain needs to be expanded, it is very simple. All miners are willing to upgrade. After all, the side chain is only business logic and does not involve the digital asset itself. The old chain cannot obtain double digital asset income like BCH forked BTC, because digital assets will not be forked on the main chain.

If the business logic of the project party still cannot meet the performance requirements using the current blockchain technology, what should be done? It's very simple. Also on the world platform, you can provide a program to connect the main chain contract with your own centralized service, deposit the world token, and publish it on the world platform, and there will be world users who provide computing power to provide this connected service .

In the entire design framework, the digital assets of the project party are completely decentralized and possess very trustworthy credibility. The architecture design of the world and world token chain platforms completely solves the problem of blockchain performance, the cost and difficulty of developing blockchain, the problem of waste of computing power, and the combination of various centralized and decentralized business logic. The problem, the problem of blockchain connecting the real world, and so on.

4. Artificial intelligence moving brick arbitrage system

The term "artificial intelligence" was first proposed at the Dartmouth Society in 1956. Since then, researchers have developed numerous theories and principles, and the concept of artificial intelligence has also expanded. Artificial Intelligence (Artificial Intelligence), the English abbreviation is AI. It is a new technological science that studies and develops theories, methods, technologies and application systems used to simulate, extend and expand human intelligence. Artificial intelligence is a branch of computer science. It attempts to understand the essence of intelligence and produce a new intelligent machine that can respond in a similar way to human intelligence. Research in this field includes robotics, language recognition, image recognition, Natural language processing and expert systems, etc. Since the birth of artificial intelligence, the theory and technology have become increasingly mature, and the field of application has continued to expand. It is conceivable that the technological products brought by artificial intelligence in the future will be the "containers" of human wisdom.

Artificial intelligence is a simulation of the information process of human consciousness and thinking. Artificial intelligence is not human intelligence, but it can think like humans and may exceed human intelligence.

• The working principle of artificial intelligence arbitrage

World Token's additional artificial intelligence arbitrage robot is developed by the technical team of Google Inc. It is used for real-time tracking and capturing of big data from major trading platforms and efficient market analysis, real-time intelligent arbitrage transactions, and users can view real-time transaction flows online.

• The meaning of "smart arbitrage robot"

The robot will automatically identify the price difference and transaction volume of the digital asset on the trading platform, decide whether to perform the arbitrage task, and initiate the arbitrage transaction by itself at the right time.

Can the robot capture the spreads of various digital assets on the major trading platforms in real time? Decide whether to trade, or exchange currency transactions and other arbitrage methods, so that the digital assets we entrust will not be affected by price fluctuations at all. Various disadvantages and risks of manual arbitrage.

• "Smart Robot" promotion plan

Worl token provides users with digital assets entrusted by users to distribute 60% of the profit of arbitrage trading through "smart robots" to worl token users and all world token promotion users.

In order to allow multiple users to participate in the world token, "robots" will also be used as a prize to reward users who are active in promotion. It is estimated that by 2020, a total of 10,000 units will be awarded, and each "intelligent robot" will be maintained for free for 3 years.

5. Digital currency bank card

In order to connect the digital currency with the physical world, world cooperates with card issuers to provide the bank debit card opening function in the wallet app, and supports users to apply for physical or virtual cards, recharge with digital currency, and conduct transactions in the physical world. And consumption. At present, the world team has established a cooperative relationship with the card issuer, and there are already bank cards that support digital currency recharge, the style is as follows:

Digital currency bank cards have the following characteristics:

• Card opening in seconds

Users only need to apply online in the WORLD Wallet APP, select the physical card or virtual card type, and fill in the basic KYC information to complete the card opening. The virtual card takes effect immediately after the card is successfully opened, and the user can use it immediately; the physical card requires a certain card production cycle, usually 2-3 weeks can be delivered to the user.

• Real-time exchange

When a user needs to use a bank card for online or offline transactions, the WORLD's wallet APP can convert any stored digital currency into the corresponding legal currency according to the current market exchange rate and transfer it to the bank card for transaction. In this way, users always hold digital currency assets in their wallet accounts, and only convert them in real time when they need to consume or trade.

• Extensive application scenarios

Bank cards issued by WORLD can be used for online and offline transactions. Whether it is online payment by domestic and foreign e-commerce companies, or domestic and overseas transfers and remittances, they can provide better rates and higher efficiency than traditional channels. At the same time, WORLD’s bank card also supports consumption at tens of millions of acceptance outlets around the world, and can also withdraw local currency from ATMs in more than 200 countries and regions. This provides great opportunities for studying abroad, tourism and business activities. convenient.

Examples of typical application scenarios are as follows:

Cross-border e-commerce shopping-when users shop on overseas e-commerce platforms and need to pay for orders in foreign currencies, they only need to bind the physical or virtual card to the corresponding e-commerce platform account to recharge the bank card with digital currency. Then use the bank card to complete the payment;

Overseas travel consumption-when users set out to travel abroad, use digital currency to open a physical bank card recharge to WORLD, and then they can make consumption and foreign currency cash withdrawal abroad, thus eliminating the trouble of foreign exchange;

Cross-border remittance-Whether it is because of studying abroad, working, or business dealings, you need to transfer and remit money at home or abroad, you can use the WORLD wallet to use digital currency to transfer money, and the other party can consume or withdraw cash and transfer in real time locally Speed ​​and rates are much better than traditional service providers.

Technical features and innovation

1. Zero-Knowledge Proof

Zero-Knowledge (zero-knowledge proof) It means that the prover can convince the verifier that a certain assertion is correct without providing any useful information to the verifier. And WORLD is using zero-knowledge proof technology to complete the cross-chain and cross-smart contract technology.

2. SHA512-ZERO algorithm encryption technology

SHA (Secure Hash Algorithm, translated as Secure Hash Algorithm) is a series of cryptographic hash functions designed by the National Security Agency (NSA) and published by the National Institute of Standards and Technology (NIST). Through the customization of SHA512 encryption technology, the SHA512-ZERO encryption technology, which is exclusively used by WORLD, has been developed to ensure the data security of the WORLD network.

3. Ring Topology Hub ring topology relay technology

WORLD’s Ring Topology Hub technology connects multiple chains to one Hub, allowing digital asset terminals to easily implement one-click cross-chain and conversion. The advantage of the ring is that the topological structure consumes much less resources than the star and tree. Few nodes and short distances may not be obvious, but with long distances and many nodes, this advantage of the ring network will be obvious. The general design structure is shown in the figure:

4. NOBLOCK technology engine

WORLD's original NOBLOCK technology engine enables the light wallet to truly achieve the lightest purpose. At present, a huge problem with light wallets is to receive the block BLOCK information of the blockchain network. Since the blockchain network realizes data security through data synchronization and redundancy, the network request of the light wallet takes up a lot of network bandwidth.

Our design idea is to let the blockchain browser become our block BLOCK data source, and we no longer synchronize the block BLOCK data. The use of the data source of the blockchain browser will bring about a problem, that is, how can the correctness of the data source be guaranteed. We adopted the design architecture of BCBP (Block Chain Browser Pool). The design diagram is as follows:

5. NO-LOCALCOIN exchange network

The NO-LOCALCOIN exchange network is based on the Achain blockchain platform to realize risk-free digital currency exchange through customized smart contracts and cross-chain gateway technology. Users on the WORLD platform or holding WORLD tokens can create exchange smart contracts, provide guarantee services by creating contracts, and use contract mechanisms to avoid defaults by parties, avoid arbitration bias by centralized custodians, and let the three parties involved have no risk of loss. After the contract creator facilitates the exchange transaction, he obtains a corresponding proportion of the guaranteed return. The overall process is as follows:

6. ZeroPay lightning payment network

The decentralization of the blockchain will bring about the problem of low payment efficiency. We use the following technologies to implement the WORLD Lightning Payment Network (essentially build a WORLD’s VPN subnet based on the existing blockchain network), and confirm the transfer within seconds to ensure that real-time credit card consumption is not affected by the blockchain. The technical design points are as follows:

• Customized mobile client, world users’ blockchain transfers are marked with SHA512-ZERO encryption;

• Develop enterprise-level blockchain nodes, detect the blockchain activities of WORLD users at any time, conduct legality verification, traffic analysis, etc. Enterprise-level nodes check continuously for 7X24 hours, analyze the balance changes provided to server users, and report to the WORLD server;

• The WORLD server receives the analysis results of the enterprise-level blockchain nodes. When the user initiates a card swiping request, it can already determine in real time whether the user has actually initiated the blockchain transfer request to prevent malicious double spending. Legend (the blue node is the sniffing node we deploy globally):
