Welcome to Libra!
This script will download and install the necessary dependencies needed to
build Libra Core. This includes:
    * Rust (and the necessary components, e.g. rust-fmt, clippy)
    * CMake
      * Clang
If you'd prefer to install these dependencies yourself, please exit this script
now with Ctrl-C.

이 스크립트는 Libra 개발에 필요한 기타등등을 모두 설치해 준다.

rustup : Rust 프로그래밍 언어 인스톨 프로그램이다. Libra core를 rust로 만들었다.
rust-toolchain
CMake
protoc : protocol buffer 컴파일러
Go : protocol buffer를 빌딩하기 위해서

아뭏든 골고루 설치한다.

2. Libra CLI 클라이언트 빌드와 Testnet 연결

아래 스크립트를 이용해서 Libra testnet에 연결 할 수 있다.

Sequence number는 계정에서 발생한 트랜잭션의 갯수다. 트랜잭션이 완료될 때마다 1씩 늘어난다. Alice 계정의 트랜잭션 시퀀스가 1이다. 이는 지금까지 Alice의 계정에서 하나의 트랜잭션, 하나의 거래가 전송되었음을 나타낸다. Bob의 경우 시퀀스가 실행되지 않았는데, 이는 Bob이 트랜잭션을 수행하지 않았음을 즉 거래를 전송하지 않았음을 의미한다.
