（二）解除质押
为保证第五城公链测试的顺利进行，在确保网络安全、稳定、高效的前提下，第五城公链在测试阶段支持快速解除质押，即用户在发起解除质押请求后，质押的数字资产将在30分钟内（此冷却时间仅适用于测试期间）返还至用户钱包。
（三）质押奖励
第五城公链的质押奖励机制是第五城独有的一种奖励机制，旨在激励各种不同条件的用户参与网络共识，目前处于测试阶段。
质押奖励包括但不限于基础的区块奖励、交易手续费的分成等，奖励将根据用户质押的数字资产数量和时长进行分配（具体的奖励机制将于后续推出）。
质押奖励的领取将十分便捷，用户只需在“节点奖励”页面中点击“获取奖励”，连接质押时使用的Web3钱包，即可一键“取回”质押奖励。
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或代币参与网络共识，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）质押的通证或代币数量相同的情况下,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）用户通过质押通证或代币获得质押奖励；
（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。

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
First, owning and staking a complete set of VCity Metaverse digital real estate (1 set = 1 foundation + 1 house) is a necessary condition for participating in VCity public chain nodes (except for ordinary nodes). The VCity public chain nodes are divided into the following roles:
1. Super Node
Rewards: Eligible for staking rewards.
Staking Requirements: Requires Mayor/Island Owner status and must stake a complete set of VCity Metaverse digital real estate to activate the node (Mayor + real estate).
Function: Super nodes are the core of the entire network, responsible for transaction validation, block generation, data storage, network governance, and maintaining overall network stability. They ensure the security, stability, and efficiency of the VCity public chain.
2. Functional Node
Rewards: Eligible for staking rewards.
Staking Requirements:
Stake a complete set of VCity Metaverse digital real estate and a node NFT (real estate + node NFT).
Stake a complete set of VCity Metaverse digital real estate, own a public IP, and stake VCity tokens (real estate + public IP + tokens).
Either of the above conditions can activate the node.
Function: Functional nodes participate in block validation, execute smart contracts, and process on-chain data, driving the diversification of the VCity public chain ecosystem.
3. Light Node
Rewards: Eligible for staking rewards.
Staking Requirements: Stake a complete set of VCity Metaverse digital real estate and VCity tokens (real estate + tokens).
Function: Light nodes primarily provide basic block validation services for the VCity public chain.
4. Validation Node
Rewards: Eligible for staking rewards.
Staking Requirements: Stake a complete set of VCity Metaverse digital real estate.
Function: Validation nodes primarily provide basic block validation services for the VCity public chain.
5. Ordinary Node
Rewards: No staking rewards.
Staking Requirements: None.
Function: Primarily used for network monitoring and data synchronization, providing basic network services for the VCity public chain.
3. Staking and Rewards
(1) Staking
In the VCity public chain, users participate in PoS consensus by staking tokens or VCity tokens to earn rewards. The staking mechanism is currently in the testing phase, with a minimum stake requirement of 1 VCity. Through staking, users not only enhance the security and stability of the network but also improve their participation and governance rights within the network.
(2) Unstaking
To ensure the smooth operation of the VCity public chain testing phase, while maintaining network security, stability, and efficiency, the VCity public chain supports quick unstaking during the testing phase. After initiating an unstaking request, the staked digital assets will be returned to the user’s wallet within 30 minutes (this cooldown time only applies during the testing period).
(3) Staking Rewards
The staking reward mechanism of the VCity public chain is unique and designed to incentivize users under various conditions to participate in network consensus. This mechanism is currently in the testing phase.
Staking rewards include, but are not limited to, basic block rewards and a share of transaction fees. Rewards are distributed based on the amount and duration of the staked digital assets (the specific reward mechanism will be introduced later).
Claiming staking rewards is very convenient. Users simply need to click "Claim Rewards" on the "Node Rewards" page and connect their Web3 wallet used during staking to claim their staking rewards with one click.
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.
