三、质押与奖励（具体规则将于后续推出）
四、经济模型
（一）代币发行
第五城公链的代币总供应量为100亿，初始供应将通过创世区块发行，后续总供应量的分配将分为几个阶段，包括开发者奖励、基金会保留、社区激励等（具体分配机制将于后续推出）。
（二）通胀与通缩机制
（1）通胀机制：每年适量增加代币供应量，用于激励矿工和验证者，维持第五城公链的持续运行和安全；
（2）通缩机制：通过销毁部分或全部交易手续费，减少市场上的代币供应，保持代币的稀缺性与价值。
（三）挖矿和验证奖励
（1）验证者通过质押通证参与网络共识，可获得区块奖励和交易手续费等，质押得越多，获得的奖励比例越高；
（2）质押的通证数量相同的情况下,按照相同等比的方式随机抽取节点进行验证交易。
（四）交易费用
所有在第五城公链上进行的交易均会产生手续费，这部分费用产生的代币部分将用于奖励矿工和验证者，部分将在需要的时候用于销毁，帮助维护第五城公链的总体价值。
（五）质押机制
（1）用户通过质押通证获得质押奖励；
（2）质押的通证将按不同类型（包括但不限于元宇宙市中心别墅、房车、外环别墅）获取不同的质押虚拟代币额度（具体对应额度将于后续公布）。
（六）惩罚机制
为确保第五城公链的稳定运行，对于出现恶意行为或离线情况的节点用户，第五城公链将会出台惩罚机制（具体机制将于后续推出）。
（七）激励机制
第五城公链将提供多种激励机制，如用户空投奖励或开发者基金等，为开发者和用户提供更多支持。
（八）流动性管理
通过去中心化金融（DeFi）平台和跨链桥为用户提供便捷的交易通道，确保市场交易顺畅，同时增加代币的市场流动性。

1. Introduction
VCity is a public blockchain utilizing the Proof-of-Stake (PoS) mechanism, allowing users to participate in network maintenance and consensus by staking tokens (Vcity), tokens representing Metaverse digital real estate, and node NFTs. VCity nodes can operate on desktop or laptop computers, and currently, installation is supported on Windows systems. Node installation and management are carried out through a combination of Docker and the official VCity node software.
2. Node Roles
(1) City Super Nodes
Rewards: Eligible for staking rewards.
Staking Requirements:
(i) Must have a Mayor (or Island Owner) status, staking a set of VCity Metaverse digital real estate to activate the node.
(ii) In the future, certain City Super Nodes will be made available to highly contributing users, such as prominent Key Opinion Leaders (KOLs).
Functions: City Super Nodes are the core nodes of the network, responsible for transaction validation, block generation, data storage, network governance, and overall network stability, ensuring the security, stability, and efficiency of the VCity public blockchain.
(2) Personal Super Nodes
Rewards: Eligible for staking rewards.
Staking Requirements: Must own and stake a VCity Personal Super Node NFT, along with staking a set of VCity Metaverse digital real estate to activate the node.
Functions: Personal Super Nodes are equipped to participate in block validation, execute smart contracts, and process on-chain data, thereby contributing to the diversification of the VCity blockchain ecosystem.
(3) Light Nodes
Rewards: Eligible for staking rewards.
Staking Requirements: Must stake a set of VCity Metaverse digital real estate to activate the node.
Functions: Primarily provides basic block validation services for the VCity blockchain.
(4) Ordinary Nodes
Rewards: No staking required but eligible for partial rewards.
Staking Requirements: None.
Functions: Mainly responsible for network monitoring and data synchronization on the VCity blockchain, offering basic network services.
3. Staking and Rewards
(Detailed rules will be announced at a later date)
4. Economic Model
(1) Token Issuance
The total supply of VCity tokens is 10 billion, with the initial supply distributed through the genesis block. The subsequent distribution of the total supply will be divided into several stages, including developer rewards, foundation reserves, community incentives, etc. (the specific allocation mechanism will be introduced later).
(2) Inflation and Deflation Mechanisms
Inflation Mechanism: An annual moderate increase in token supply is used to incentivize miners and validators, ensuring the continued operation and security of the VCity public chain.
Deflation Mechanism: Part or all of the transaction fees are burned to reduce the token supply in the market, maintaining the scarcity and value of the tokens.
(3) Mining and Validation Rewards
Validators participate in network consensus by staking tokens or VCity tokens and can earn block rewards and transaction fees. The more tokens staked, the higher the reward ratio.
Nodes with the same number of staked tokens will be randomly selected to validate transactions in proportion to their stake.
(4) Transaction Fees
All transactions on the VCity public chain incur fees. A portion of the generated tokens will be used to reward miners and validators, and a portion may be burned to help maintain the overall value of the VCity public chain when needed.
(5) Staking Mechanism
Users earn staking rewards by staking tokens or VCity tokens.
Staked tokens will acquire different virtual staking token amounts depending on the type (including, but not limited to, Metaverse central city villas, RVs, outer ring villas) (the corresponding amounts will be announced later).
(6) Penalty Mechanism
To ensure the stable operation of the VCity public chain, a penalty mechanism will be introduced for nodes that exhibit malicious behavior or go offline (the specific mechanism will be introduced later).
(7) Incentive Mechanism
The VCity public chain will offer multiple incentive mechanisms, such as airdrop rewards for users or developer funds, to provide more support for developers and users.
(8) Liquidity Management
Through decentralized finance (DeFi) platforms and cross-chain bridges, users will have access to convenient trading channels, ensuring smooth market transactions while increasing the market liquidity of tokens.
5. Node Installation Guide
(1) System Requirements
Operating System: Windows 10 or later (64-bit system recommended)
Memory: At least 8 GB
Storage: 1 TB SSD or larger
Processor: 8 cores or more
Network: High-speed and stable internet connection (at least 10 Mbps)
Note: These are the basic server configurations required to start a node. If the basic requirements are not met, the node will not be able to start.
(2) Installation Steps
Check System Version:
Open "Settings" -> "System" -> "About" to check your Windows version.
If the system is not up to date, go to "Settings" -> "Update & Security" -> Click "Check for updates."
Install Docker:
Visit the Docker official website and download the Docker Desktop software for Windows.
Install Docker Desktop and enable WSL2 support (Windows Subsystem for Linux) during the installation process.
After installation, open Docker Desktop to ensure Docker is running correctly.
Download and Install VCity Public Chain Node Software:
Go to the VCity public chain official website and download the latest node installation package.
Run the installation package and follow the prompts to install the VCity public chain node software.
After installation, start the VCity public chain node software and bind your wallet address.
Run the Node:
Open the VCity public chain node software.
The software will automatically configure Docker and start the relevant blockchain services.
Stake the corresponding tokens to activate the node.
Ensure the node remains online to receive rewards for participating in the PoS network.
