    # Botnaix 交互之生态篇--Palladium 去中心化的稳定币发行协议 ![Square_Palladium Logo](https://hackmd.io/_uploads/BySA7-Ohyl.png) [TOC] ## palladium 是什么 简单来说palladium就是在Botanix之上构建的满足BitcoinFi市场需求,提供比特币运行和扩展的稳定币协议,这里抵押后获得的稳定币叫做PUSD。听起来有点绕是吧,你可以把它理解为市场的USDT/USDC,区别在于USDT/USDC的锚定对象是由中心化银行控制的法定货币USD$, 这样是不是好理解点. 那这些稳定币起什么作用呢?你还是可以用现有的理解,类似于USDT在以太坊DeFi生态中的作用。它可以作为DEX、借贷协议、支付系统中充当交易和清算单位,如果没有类似于一个稳定的中间货币作为中介试想下这些资产如何锚定交换。在alladium平台上用户可以使用BTC抵押来进行借贷、支付和投资,而无需卖掉比特币。任何用户可以将BTC存入Palladium 作为抵押,铸造出PUSD,获得无息流动性(即借出资金而无需支付利息) 那这玩意如何能保证它自身稳定性呢,通过经济驱动的套利机制,这里我刚好自己之前也不是太清楚多絮叨几句,就浅浅的多研究研究,不知道理解的对与不对,希望看到的大佬能指点一二 --- ### USDT的稳定性保障 这里还是先说USDT的稳定性如何保障,这个好理解 - **由 Tether 公司负责**: - 每当用户存入 1 美元,他们会铸造 1 USDT,并承诺用户可以随时赎回 1 USDT = 1美元。 - **锚定方式**: - USDT 的稳定性依赖于 **中心化银行资产**(如现金、债券)。 - **风险**: - USDT 的稳定性取决于 **Tether 公司的信用**。 - 理论上,如果 **Tether 破产或拒绝兑付**,USDT 可能会失去锚定。 --- ### PUSD的稳定性保障 --*划重点* USDT和法定货币直接锚定,可这个稳定币锚定的资产是BTC,本身BTC的价格就不稳定,他要要稳定成和美元1:1的比例,这玩意不好理解。 PUSD不是用美元作为储备,而是通过 **超额抵押 BTC** 来支撑其价值,这也是palladium平台的核心作用,它的稳定性来源于几个核心机制: - **超额抵押 BTC** - 用户用BTC作为抵押,按照**高于1美元的BTC价值**来铸造PUSD。 - 例如:用户抵押**130美元的BTC**,可以铸造**100 PUSD**(抵押率130%)。 - 这样即使BTC价格波动,PUSD仍然有足够的抵押资产支持。 - **PUSD价格高于1美元 → 鼓励新铸造** - 如果 **PUSD 价格>1美元**,套利者会抵押BTC铸造PUSD,并在市场上卖出PUSD 以获利。 - **更多的PUSD进入市场**,供应增加,PUSD价格下降至1美元。 - **PUSD价格低于1美元 → 赎回BTC,减少供应** - 由于**PUSD始终可兑换1美元等值的BTC**,当市场价格跌至假设 **0.98美元** 时,套利者会: - 低价买入PUSD。 - 在协议中按 **1:1兑换BTC**,获得套利收益。 - **赎回PUSD,减少市场供应**,价格自然回升到1美元。 - **清算机制:防止BTC价格暴跌带来的影响** - 当BTC价格下跌,如果某些用户的**抵押率降至110%以下**,系统会自动: - **清算部分BTC资产**,用于回购PUSD并销毁。 - **减少市场上的PUSD供应**,维持稳定性。 通过以上机制平台就实现了一种无治理机制,不依赖主动治理或货币干预,而是通过经济驱动的用户互动和套利来维持挂钩稳定性,许多DeFi项目依赖治理代币来管理系统参数,这可能会被鲸鱼操控(如攻击者持有大量治理代币,通过投票改变规则). --- ### 两者比较 | **特性** | **USDT** | **PUSD** | |------------|----------------------------------------------|-------------------------------------------| | **锚定方式** | 由中心化机构 Tether 以银行资产背书 | 由 BTC 作为超额抵押支撑 | | **稳定性来源** | Tether 承诺 1 USDT = 1 美元 | 市场套利 + 赎回机制 | | **资产依赖** | 依赖银行储备 | 依赖 BTC 抵押 | | **透明性** | 由 Tether 公司控制,资产储备不透明 | 运行在智能合约上,链上可验证 | | **去中心化** | **中心化** | **去中心化** | --- ### 总结 Palladium 是一种协议,而不是一个平台。Palladium 为用户提供了铸造 PUSD 稳定币的能力,无需支付任何利息或定期费用。作为一种算法控制的货币工具,Palladium对新提取的流动性实施一次性借款费,这对于维持与美元挂钩至关重要。 之前看过一本关于银行体系的书里有一句总结的比较好的话,其实从传统银行看defi领域也是一样,银行就干两件事增加流动性,控制风险。整个defi也是围绕着这两个要素来建设的。 理解了上面的内容才知道自己在平台上交互的时候都在干啥,要不然点来点去,一脸懵逼,🤔 等会交互的时候,我们看到trove,mint,repay,close就知道自己在干啥了。 ## 任务平台任务: * ~~[intract](https://quest.intract.io/quest/67a0d29ced2e945bac734067?campaign_initiator_type=alphaHubNarratives&campaign_initiator_id=67a1e8f0ed2e945bac7543fe&card_position=0) ~~ 这个错过了,本来可以mint botnaix的第一个NFT,来的晚了,没mint到,原本也想把这个平台放到后面来写,可惜当前的任务这两天官网交互由有问题,索性把这个当补功课 * [zealy](https://zealy.io/cw/palladiumlabs/invite/nrLfqGtvR-5eB_BeiAqtg) 按照提示完成就好了,里面比较麻烦的是两个平台linkedin和medium还要flow他们并截屏上传 ## 社区三件套 * [X](https://x.com/PalladiumLabs) * [Discord](https://discord.com/invite/9MMEyJ4JDz) DC角色: - @Verified --已验证用户(所有通过验证的成员) - @OG Palladium --OGs(社区的早期成员或早期支持者)这个估计已经结束了 - @Pioneer --活跃贡献者(为社区做出积极贡献的成员) - @Ambassador --核心贡献者(为社区带来重要价值,并在社区外代表我们的人) DC社区没啥好说的都是多活跃,主动奉献,牛马精神拿出来 * TG 好像没看到 ## 测试网交互 1. ***第一步连接钱包*** ![image](https://hackmd.io/_uploads/BygAPW_hyx.png) 2. ***领水*** 其实按道理来讲本身可以使用BTC作为抵押物来直接交互,但是平台本身为了缓解水龙头压力也提供了对等替代WBTC水给大家,但是领取WBTC的先决条件是你钱包里必须先有一点btc作为gas费,这个可以参考我上一篇文章[Botanix 测试网交互](https://hackmd.io/ttDOGDyBQdOeIrZKbrrTGg) ![1742374588023](https://hackmd.io/_uploads/BJr08Zdn1x.png) 3. ***open trove*** 刚看到这个trove可能比较困惑,以为开个宝盒,其实在defi环境中它就是抵押借贷这么概念吧,就是我们前文提到的用BTC来超额抵押兑换成PUSD ![image](https://hackmd.io/_uploads/Syf9xMd2kg.png) 输入你要抵押的WBTC的数量,系统会自动的计算你可以铸造的最大数量PUSD ![image](https://hackmd.io/_uploads/H1cqXMOnJg.png) 输入您想要铸造的PUSD数量后,您可以在右侧信息面板中查看Trove的其他详细信息 ![image](https://hackmd.io/_uploads/S1BNrMO21x.png) 这里面第一次做就有困惑了,什么是Loan-To-Value,其实就是我们说的超额抵押,只不过之前我们说的抵押物和借贷产品两个对象最为分子分母对倒了,在抵押物WBTC固定的情况下,你可以试着调整PUSD的数量(但是不能低于平台限制的100),看看生成的订单order有什么区别,相同价值的抵押物,你借出来越少,它清算的价格就越低 4. ***update trove*** 你也可以随时调整你的抵押比例您可以存入更多 WBTC 来改善您的资产状况。如果您只想添加抵押品,则不必铸造新的PUSD。同样,如果您的LTV允许,您也可以铸造更多 PUSD 而不提供任何额外抵押品。您只需将其中一个输入框留空,交易就会通过。 ![image](https://hackmd.io/_uploads/ByJ5Fz_nyg.png) 5. ***repay*** 名字叫偿还,其中有两个选项,一个是偿还借出来的PUSD这个好理解,另外一个叫Withdraw Collateral,其实就是在LTV阈值允许的情况下,把你多余的抵押物BTC取出来,感觉这个不应改放到repy选项卡,个人觉得 ![image](https://hackmd.io/_uploads/S1zZLm_h1x.png) 6. ***close*** 这里又要画个**重点**了,我之前尝试了几次都关闭不掉,要close这个order你需要满足两个条件,第一必须全额偿还全部债务,也就是repay哪里完成所有PUSD的归还,第二呢,你钱包里要有PUSD支付协议费用,由于我刚开始在生态里做,钱包里除了这个平台借贷的PUSD,没有多余的了,偿还完PUSD,就没有PUSD用以支付这笔费用了。你如果和我情况一样,需要先去bonaix生态的 [bitzy](https://bitzy-testnet.vercel.app/swap) swap一点PUSD到你钱包 ![image](https://hackmd.io/_uploads/SyeZdEu2Jl.png) 7. ***stake/unstake/cliam*** 这块好理解,你可以通过质押获取到的PUSD(不知道什么情况下什么人会这么干,证明自己理解还不充足)当然也可以通过生态以后完善了其他地方赚取的PUSD,通过质押方式为PUSD稳定币池提供流动性,从而获取收益,三个选项都做下 ![image](https://hackmd.io/_uploads/HyB9OXdhyx.png) 8. ***rovBTC*** 你也可以通过生态中其他平台[rover](https://testnet.roverstaking.com/stake)用抵押方式获取到的rovBTC做以上3-7步的所有过程,过程与通过WBTC完全一致,这里就不再重复了 ![image](https://hackmd.io/_uploads/BJDoOLd21g.png) 9. ***dashboard主页*** 这里也没什么好说,就是完成了指定任务领取指定徽章,有交易数的有连续打卡天数的,多交互勤交互增加积分就对了,可惜了错过了早期两期的NFT mint,后期参与应该还有NFT。 ![image](https://hackmd.io/_uploads/BJry54dhyl.png) ## 总结 以上就是所有的平台任务了,任务不多,平台看起来也不复杂,其实是大巧若拙,暗藏玄机。自己理解也有限,有些东西并没有完全理解。 比如平台所说的两层抵押,恢复模式,投资者如何在平台中收益最大化,这些问题都有待思考,留个课后作业,也希望大佬们看到了能指点迷津 ## 遗漏的地方 平台里还提到有bPUSD 抵押收益代币,我的理解就是抵押后产生的收益代币,但是官方文档好像还没有说明其运行机制和收益模型,后续看到了再完善 ## 写在后面 整个botnaix项目生态尚处于早期阶段,看到的朋友们仍然可以尽早参与进来,你也可以加入我们[Botanix 中文 Yapper](https://x.com/i/communities/1896923200002596955) 社群,一起迎接2025 BTCFi 元年的来临 我虽然刚参与社区几天,这里还是感谢下dc群里的各位老师们,特别是 ***(孤独是病灬得治)aifei1*** 特别鸣谢群里***zzzzztai*** [X账号](https://x.com/pengyuyuan123) 芋圆大佬及leader WADE [BotanixLabsCN](https://x.com/BotanixLabsCN)的指点推广 **botanix中文社区请扫描加群:** ![image](https://hackmd.io/_uploads/Synddb7fee.png) ## 其他参考 官方一个简介视频,感兴趣可以观看: <iframe width="560" height="315" src="https://www.youtube.com/embed/58KcsjLsCl4" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe> ****** ![image](https://hackmd.io/_uploads/BJGfeprnkx.png) Write by Xuemiaolan | [Twitter](https://twitter.com/xuemiaolan) 时间:2025年3月19日
