web3 数据可移植性如何降低中心化服务的能力🧵
对于刚接触 web3 的人来说，可能会感到困惑的一件事是查看 OpenSea 等服务上的用户资料。例如，这是我的 OpenSea 配置文件https://opensea.io/cdixon.eth
我的 OpenSea 个人资料
如果你习惯了 web2，你可能会认为 OpenSea 持有我个人资料页面上显示的数据和 NFT。
事实上，数据和 NFT 都由我持有，而 OpenSea 只是提供对这些数据的看法。
您可以通过转到其他服务并查看我的个人资料轻松确认这一点。

开演时间 -https://showtime.io/cdixon.eth
更多技术人员可以直接在以太坊区块链上查看数据。
在这些示例中，您将看到的主要是艺术和游戏对象（以及我的 .eth 名称），但未来 NFT 将拥有强大的数据集，包括完整的社交图谱
为什么数据可移植性很重要？
这意味着如果这些服务开始收费过高、插入广告和算法提要、限制他们的流量或以其他方式虐待他们，用户可以轻松地切换服务。
这类似于 web1 的工作方式。例如，我主持http://cdixon.org 在网络托管服务提供商处。如果主机开始出现问题，我可以轻松地将我的数据移动到另一台主机并切换我的 DNS 记录，以便http://cdixon.org 指向那里。
而且我可以在不失去通过入站链接、搜索引擎优化、电子邮件订阅者等长期积累的受众的情况下进行此转换。
将此与 web2 进行比较。许多人花费数年时间在 web2 服务上建立受众，但如果这些服务决定减少您的有机覆盖范围或以其他方式出现不当行为，则基本上不可能转换。
web3 像 web1 一样工作。 web3 中将内置集中式服务——其中许多将非常有用——但它们的经济能力和整体控制将受到数据可移植性带来的较低转换成本的限制。
这就是为什么 web3 的采用率大大低于 web2 的采用率。例如，OpenSea 对交易收取 2.5% 的费用。
将此与 web2 的采用率进行比较。 FB、推特和Instagram 拿走 100% 的收入。 YouTube 拿走了 45% 的收入。苹果和谷歌应用商店占 30%。
较低的采用率将使 web3 服务对无法在 web2 平台上建立可持续业务的创作者特别有吸引力。
web2 的 take rate 是 web3 的机会

错误的问题：是否涉及中心化服务？
正确的问题：是否有中心化服务*具有高转换成本*？
