# Tale扮演的角色

**Tale扮演的角色**

Tale由3个组件和相应的机制组成，每个组件在Tale网络中都扮演着非常重要的角色，从而使其成为一个安全且不受信任的Oracle。

数据提供者和激励机制：Tale允许机构节点通过存放资产来提供价格信息。第一批机构代码将通过Tale Oracle的邀请生成，所有节点都将确保独立且互不干扰。为了完全透明和公平，整个网络将定期选择后续节点。任何机构/个人都可以通过存放资产来成为数据提供者。 KTO（OIP-10）将作为奖励，奖励其价格已成功验证为有效的提供商。

价格调用者和调用函数：价格调用者也是所谓的oracle服务购买者，他们指定包含某些资产的价格，任何账户或智能合约的要求，可以将其表示为价格调用者。如Tale Oracle中所述，可以自由调用节点提供的任何常见价格馈送，但是，如果要求某些稀缺资产（例如黄金，股票等）的价格，则价格调用者需要支付额外的费用。这种机制实际上是回购和刻录KTO（OIP-10），以保持价格的稳定。

**验证者和验证机制：**&#x62E5;有一定数量的KTO的用户既可以是验证者，也可以是仲裁者。如果怀疑数据提供者破坏了相关凭证以进行恶意活动，则需要通过将KTO存入来验证提供者提供的价格。投票将在Tale网络上启动，仲裁员将决定提供者提供的数据是否是欺诈性的，如果是，则数据提供者存放的KTO将获得奖励给验证者，仲裁者，并按比例分配给流动资金池。

&#x20;**Roles of** **Tale Actors**

Tale consists of 3 components and corresponding mechanism, each of them play a quite important role in Tale network, enabling it to be a secure and trustless oracle

**Data Provider & Incentive Mechanism:** Tale allows institution nodes to provide price feed by depositing assets. The first batch of institution codes will be generated through the invitation of Tale Oracle, all nodes are sure to be independent and no-interfering. In order to be fully transparent and fair, subsequent nodes will be elected periodically by the whole network. Any institution/individuals can be data providers by depositing assets. KTO (OIP-10) will be rewarded as incentives to the providers whose price is successfully verified as valid.

**Price Caller and Call Function:** Price caller are also so-called oracle services purchasers who specify requirements that contains the price of certain assets, any account or smart contract can be denoted as price caller. As it is described in Tale Oracle, any common price feed provided by nodes are free to be called, though, price caller is required to pay extra fee if the price of certain scarce assets such as gold, stocks etc. are being requested. This mechanism is actually to buy back and burn the KTO (OIP-10) in order to maintain the stability of the price.

**Verifier and Verification Mechanism: T**he users who hold a certain amount of KTO can be both verifiers and arbiters. If there is any doubt that the data provider compromises relevant credentials to undertake malicious activity, the price feed offered by provider will need to be verified by depositing KTO. Vote will be launched on Tale network, arbiters will decide whether the data offered by provider is fraudulent or not, if so, KTO deposited by data providers will be rewarded to verifier, arbiter as well as allocated to liquidity pool proportionally.
