像电子断层扫描这样的三维电子显微镜技术提供了对细胞结构的有价值的见解，并对数据的存储和传播提出了巨大的挑战。在这里，我们探索了一种新的方法来公开发布我们团队收集的11,000多个这样的数据集，总共超过30 TB。我们的方法基于围绕区块链分类账构建的对等文件共享网络，提供了一种分布式数据存储解决方案。此外，我们还提供基于浏览器的用户友好界面https://etdb.caltech.edu，，供有兴趣浏览和下载我们的数据的任何人使用。我们讨论了该系统的相对优势和劣势，并为其他小组提供工具来挖掘我们的数据和/或使用相同的方法来共享他们自己的成像数据集。
Three-dimensional electron microscopy techniques like electron tomography provide valuable insights into cellular structures, and present significant challenges for data storage and dissemination. Here we explored a novel method to publicly release more than 11,000 such datasets, more than 30 TB in total, collected by our group. Our method, based on a peer-to-peer file sharing network built around a blockchain ledger, offers a distributed solution to data storage. In addition, we offer a user-friendly browser-based interface, https://etdb.caltech.edu, for anyone interested to explore and download our data. We discuss the relative advantages and disadvantages of this system and provide tools for other groups to mine our data and/or use the same approach to share their own imaging datasets.
