这里实时更新了Substrate相关的新闻、活动、学习资料。
Substrate是一个开源的区块链构建框架，可以在短时间内建立完整、可配置的区块链。另外一个可选功能是，可以将构建的区块链部署到Polkadot网络中，这一网络拥有共享安全等其它优势。更多内容参考这里。
使用Substrate，你可以获得下面这些开箱即用的功能，还可以自定义这些功能：
- 一条PoS的区块链
- 可升级的运行环境
- 插件式的共识 (PoS, PoW, PoA)
- 区块生产和同步
- 高效存储
- 高效状态机
- P2P网络层
- 内置的基本加密工具
- 支持轻客户端
- 工具集，用来修改运行环境的逻辑，例如管理存储、账户、权益、资产、共识算法等等
- UI工具
- 正在招聘: Rust开发工程师，运行环境工程师，发布经理，具体职位信息请看这里。
- [4月26]: Ink初始版本发布: 基于Substrate的智能合约DSL可以进行试验了。
- [4月9]: Parity Fether: 以太坊桌面钱包上线！
