Blockchain Webinar and Blog
http://medium.com/flipay/blockchain/homeAs I believe in the future of blockchain, I don't want anyone to miss the opportunity to learn, build, and invest in such incredible technology. 但问题是，人们——甚至是开发人员——很难真正理解这项技术. And most importantly, 确保对安全和基本原理有足够的了解，以保护自己免受许多可能导致资产损失的威胁.
因此，我花了一些时间在网络研讨会或博客上分享知识，以帮助人们更多地了解区块链技术, strengthening the community for a better future together.
