This article will describe a decentralized, secure, high TPS, scalable, carbon neutral, and developer-friendly Vision Chain, mainly through performance, trusted network, basic ecosystem facilities, underlying application solutions, VS economic model, etc., in multiple dimensions, we will introduce the Vision virtual reality network to everyone. At the same time, we hope to introduce more partners to promote the development of the Vision ecosystem, expand usage scenarios, and promote the construction of the developer community. We also welcome blockchain technology enthusiasts to contact us and build the Vision ecosystem together.
A metaverse public chain focusing on "scalability", "speed", and "security"
Vision is a high-performance public chain built for the Metaverse. The vision is to build a metaverse portal and infrastructure platform that supports complete decentralization and high performance of large-scale applications and creates a prosperous, open, and inclusive metaverse ecosystem. Vision is considered to be one of the most secure high-performance public chains, due to the well-designed architecture and code, Vision has better operating efficiency and stability than most public chains.
Performance
Vision has introduced the PBFT consensus mechanism in the latest version 4.1. Blocks produced by supernodes are sent to each supernode for consensus, which means that the production of the current block is synchronized with the consensus of the previous block, which greatly speeds up the speed of the block passing through the consensus. Currently, only 4 blocks (12 seconds total) are required to complete, transactions can be completed in one second and cost as little as 1 cent, providing developers with an efficient and low-cost on-chain environment.
Vision code is completely open source and fully compatible with Ethereum. DAPPs can be deployed at a very low cost and experience the high performance of Vision. Developers can build on Vision using Solidity and the tools they are already familiar with: Remix, Truffle, and MetaMask. And DAPP can be deployed just like on Ethereum to support the large-scale application of the Metaverse.
Vision adopts the VPoS mechanism to ensure the security of the chain. Proof of Stake is a consensus mechanism for validating transactions in new cryptocurrencies. Through Proof of Stake, participants called "validators" need to stake VS tokens in Vision's smart contracts, replacing physical miners with staked mining. In exchange, they have the opportunity to validate new transactions and earn rewards. However, if they incorrectly validate bad or fraudulent data, they lose all tokens as a penalty.

Trusted Network
The Vision VPoS consensus mechanism changes the implementation path of "seeking consensus among untrusted nodes" to "letting nodes be trusted and perform computations", which can support the development of large-scale decentralized applications and deploy applications on the chain, applications will serve users permanently, and all information will be permanently stored in the metaverse. It cannot monopolize the user's information and does not have the right to interpret users' virtual rights. It can only simply provide the service functions of the platform, and through smart contracts, realize the decentralized operation.
Advantages of Vision Chain under the Vpos consensus mechanism:
Deliver value
Protect user privacy
Users can get more benefits
Refactoring production relations

TNode
1. Introduction
Vision's validator nodes form a global, trustless, leaderless proof-of-stake network. All verification candidates, verification partners and first validators play an important role in the Vision network governance system. They must not only ensure the stable operation of network verification nodes, but also actively participate in governance, and have the right to initiate proposals to modify Vision network parameters.
2、First Validators
In the Vision network, every VS token holder has the opportunity to become the first verifier or verification partner of Vision. After spending the application fee of 900VS, it becomes a verification candidate, and the verification candidate can accept the user's vote. The top 23 candidates with the highest number of votes can become the first validators, and the 24th to 123rd candidates become validator partners. The first validator has the obligation to produce blocks and package transactions, and each time a block is produced, the income is 0.12VS. The 23 first validators and the top 24~123 validating partners can also obtain node income based on the number of votes, and the annualized rate of return is expected to reach 46%.

Basic ecosystem facilities
① Vision Bridge: Break the gap between public chains and solve the "ecosystem island" problem of Metaverse development; realize the intercommunication between projects on the same public chain, and realize the interaction and integration of multiple public chains.
② Vtimes Wallet: Provide support for the metaverse economy and society, satisfy the decentralized digital wallet, and integrate wallet, data, metaverse, transaction, and other functions.
③VisionScan：Explore and search Vision Metaverse on-chain activity, providing users and developers with real-time data on blockchain usage.
④Vanswap：The operation of Vanswap's governance system using NFT will be a new model for NFT to shape the operation, operation and governance of the future metaverse world, and realize the metaverse life of DeFi protocols and NFT applications.
⑤VISION NFT marketplace：The upcoming VISION NFT market, on the one hand, can build the basic transaction order of the Vision Metaverse and maintain the decentralization of the Vision Metaverse; on the other hand, users can participate in entertainment, work, social interaction and participation in the Vision Metaverse in a new way, trade and profit, opening up more social and economic options.
Based on these ecosystem facilities, we can expand in the higher-order direction of the metaverse, until we create an on-chain world that is truly immersive, interactive, and conceptual.
Underlying application solutions
1、 Oracle
VictorLink does not differentiate between oracle contract owners and oracle node operators. That is, the operator of the oracle node is also the owner of the oracle contract. The oracle node account only handles data sources and data submission, and the oracle contract owner can call the contract and withdraw the usage fee paid by the oracle contract user. Provide smart contract developers with comprehensive tools and data, connect thousands of nodes to provide accurate, secure and credible data transmission services, provide high-quality data services for Metaverse applications, and reduce their data acquisition and use costs.

2、Metaverse Engine
GoEngine is a 2D and 3D multi-terminal game development engine under the Vision ecosystem. Users can quickly use GoEngine to develop 2D and 3D games on Android, IOS, and the Web, and can quickly access and interact with the underlying Vision. The engine API is fully compatible with cocos-engine and now supports Cocos-Creator version 3.5.0.
The engine is completely open source and continues Vision2d-x's advantages of customizability, embeddability, ease of learning, and small package size. With deep support for all major platforms, games can be quickly published to iOS, Android, Windows, Mac, Web and every small game platform. A pure Javascript engine runtime is provided for better performance and smaller package size on web and small game platforms. On other native platforms, the underlying framework is implemented in C++ to provide greater runtime efficiency.

VS economic model
1、About VS
VS will initially issue 1,000,000,000 tokens, and there will be no additional issuance for the time being. In the later stage, the community nodes will vote to decide whether to implement it. VS is the utility token and unit of value in Vision, the core of Vision's economic model. The Vision ecosystem and its metaverse applications can function normally through VS, and the ecosystem value of Vision will be expressed by VS.
2、The new version freezes function improvement
①5-level freezing period: 5 new freezing periods have been added, which are 30 days, 60 days, 90 days, 180 days, and 360 days. Users need to choose different period time to freeze. The pledge coefficient has been increased, which are 1.0 for 30 days; 1.1 for 60 days; 1.2 for 90 days; 1.3 for 180 days; 1.5 for 360 days.
② Batch freezing: The pledge coefficient is calculated comprehensively. In order to facilitate user operation, we have enabled users to freeze multiple period time in batches at one time. When calculating the coefficient, the coefficient is calculated by the comprehensive average coefficient of the coefficients of multiple periods of time. The highest coefficient is 1.5, the higher the coefficient, the higher the income
③ Reinvestment Period: The new version adds a consideration period for reinvestment. After the user's freeze period expires, we will have a reinvestment period. During this period, the user can manually click to unfreeze; during the continuous period, the user still enjoys the original coefficient income. If the user does not unlock during this period, after the expiration date, then the system will consider the re-investment freeze, at this time, the user needs to manually click the re-investment function to calculate the new round of unfreeze time;
④The reinvestment consideration period includes two modules: voting and community node voting
3、Community Node Voting
Participating in community voting means that the VS user held will be locked and cannot be traded. It will be used as collateral for the reward
Vision community node voting mechanism supports and can only vote for one node. The specific operations are performed in the wallet as above. The freeze type ResourceCode is set to 3, and the receiverAddress is the community node address set by the current account, which is a required parameter. Frozen_balance is more than 1vs, and when CommunityVoting initially frozen, it was saved at receiverAddress. Vision community node voting mechanism, if the conditions are met, the operation when modifying the node address is to set frozen_balance to 0, the receiverAddress exists, and cannot be the old node address. Vision community node incentives support repeated freezing.

4、resource model
In order to allow users to get the ultimate experience and gain more benefits, Vision introduces two resource concepts: entropy and photons. On the Vision network, entropy is CPU and storage, and photon represents the time consumed by smart contract execution. Both entropy and photon can be obtained by freezing VS. Users can not only obtain entropy and photon for free, but also obtain frozen annualized rewards. The obtained entropy or photon can automatically deduct the transaction fee or the "gas" fee required to call the contract, namely VS.
