使用chrono库,我们可以很容易地获取当前的UTC时间或本地时间。以下是一个获取当前UTC时间的示例: rust use chrono::Utc; use chrono::DateTime; fn get_current_utc_time() -> DateTime<Utc> { Utc::now() } 如果你需要获取本地时间,可以使用Local代替Utc: rust use chrono::Local; use chron...

还需要考虑如何实现区块链的核心功能,如工作量证明(PoW)、哈希计算、交易签名等。在Rust中,这些可以通过现有的库来实现,比如sha2用于哈希,chrono处理时间戳,serde和bincode用于序列化存储。同时,需要设计命令行工具或简单的前端界面,方便用户查询积分和交易记录,这部分可能需要后续开发,但初期可以先用CLI工具。
