FTX崩盘后,更多的资金流向了非托管钱包,而传统的钱包采用的是单方签名模式,对私钥安全性的依赖极高。这也导致了黑客更多的攻击去盗取私钥。 钱包是WEB3的入口,因为底层合约交互的时候,是通过私钥进行签名检验,也是导致目前钱包无法绕开私钥的原因。目前市面上的钱包产品多少都存在被盗风险,以及私钥/助记词忘记风险。 解决方向是MPC钱包和智能合约钱包,智能合约钱包因为牵涉到底层合约及多方面升级,难度更大,所以,MPC钱包在当前更具可行性。一、什么是MPC安全多方计算(Secure Multi-party Computation, MPC)是隐私计算技术中的一种,是基于密码学的协同计算框架,可以广义理解为,多方各自有私密的输入来一起完成计算任务,期间可以保证各自的私密输入不会泄露。而MPC钱包则是通过对私钥进行多方计算,分散控制权以达到分散风险或提高备灾的目的,从而有效避免单点失败等安全问题。 因此在密码学中,对于保存用于解密数据或生成数字签名的私钥非常有用。二、MPC钱包实现方式MPC钱包,简单来说,就是将一个私钥打碎成多片,将私钥碎片交与一个去中心化的网络进行计算和加密。当需要私钥签...

AMA回顾—— Open Campus Publisher NFT第二季
Open Campus作为Web3教育领域的领军者,其Publisher NFT第二季即将上线。记得提前订好小闹钟⏰,以免错过这次机会!存款开启时间:11月23日 17:00 (UTC+8) 铸造时间:11月27日 17:00 (UTC+8)1.Snowball: 在官方推特上看到Open Campus即将发布第二季Publisher NFT的消息,可以给大家介绍一下这个Publisher NFT是什么吗?第一季取得了什么样的成绩?Alan Lau:感谢大家的参与,让我为大家进一步介绍Open Campus和我们的代币EDU。我们是一个致力于解决教育市场问题的平台。在这个市场,我们看到许多老师虽然付出巨大努力,但他们的待遇并不高,他们的课程也缺乏知识产权保护。 为了解决这个问题,我们推出了publisher NFT,这是Open Campus的核心产品。通过这个产品,我们可以将老师们的课程转换成NFT,然后转售给新的投资者。这些投资者不仅看重课程的投资价值,还为课程提供更多的传播机会。 以一个例子来说明这个机会。我们与Tiny Tap合作,他们提供了一些针对儿童的课程。这些课程在...

AMA回顾——Web3教育龙头Open Campus的过去和未来
Open Campus 是一个结合教育创作与区块链技术的平台,随着Binance将其设为第31个Launchpad项目上线,相信很多小伙伴都很看好Web3教育行业未来的发展很高兴邀请到了Open Campus 品牌首席业务官Alan Lau,一起探讨一下Web3教育行业存在的可能和Open Campus独有的特长和优势 **1.Snowball:**很多关注Open campus的人都关心TinyTap和Open Campus的关系,您能简单介绍一下吗? **Alan Lau:**当Open Campus成立时,我们的愿景是能够覆盖整个教育领域。因此,我们希望将其建立为一个多项目平台。一开始,我们已经有了5、6家公司加入了这个平台,并愿意使用EDU进行构建。其中,TinyTap是其中一家非常重要的合作伙伴,与Open Campus的关系密切。Open Campus作为Protocol的发起者,EDU是由Open Campus发行的。TinyTap作为其中一个重要的合作伙伴,是首批重要的启动公司之一,具有十年的教育内容开发经验。 TinyTap的团队来自科研大国以色列,因此其研发和...

Superdao其实做的事情是dao细分领域的事情,给大家提供一个dao的创建,管理和成长工具。这一点有点像a16z投资的syndicate(https://syndicate.io/ syndicate也是一个必参与项目,不过那个已经上线主网)。目前已经完成了1150万美金的融资。投资方包括Alliance、DIGITAL、One Block Capital、Fika Ventures、Pear Ventures,以及种子前投资者Shima Capital和Fifty Years。来自 1inch、Protocol Labs、Mercury、Golden 和 Request Network 的创始人,以及来自 Coinbase、OpenSea、Rainbow、Kraken 和 Telegram 的产品负责人也加入了这轮融资。
投资背景相对不错,然后做的事情其实在未来想象空间比较大。毕竟从dao诞生以来,其严格来说并没有事实上爆发过。所以在不付出真实成本的情况下,大家可以参与一波:
准备物料有:邮箱,erc20地址,推特,discord
答题链接:https://test.superdao.co/t3st?source=superdao-site
总共有31道题,要求是20分钟内,其实背过答案,答起来挺快的。目前的情况是题目顺序不会变,但选项的顺序会发生变化。答对的分数会影响获得的NFT的等级,建议各位小伙伴根据以下的答案认真选择。

A distributed database that maintains a continuously growing list of ordered records called blocks
2.What is the most accurate description of a block?
A collection of transactions on a chain

A fixed number of characters produced by an algorithm and used to secure blockchain transactions
4.Which of these statements about PoS is true?
Validators check transactions and add new blocks to the blockchain
5.How does the node infrastructure work?
It allows programs to use information from the blockchains faster
