이더리움 - 프라이빗 블록체인 만들기 (2)


여기에서 이어집니다.

자바스크립트 기반의 콘솔입니다.

1. 어카운트 확인하기

> eth.accounts
["0x44e74080949320292839b9a0df55e4459dd51434"]

아까 생성한 한계의 어카운트가 보입니다.

2. 잔고 확인하기

> eth.getBalance(eth.accounts[0])
300000

첫 제네시스 블록을 만들때 alloc 했던 양 만큼 할당이 되어 있네요.

3. 단위 변경하기

그런데 저 단위는 사실 ether가 아니고 wei입니다. 아래 처럼 변환하면 됩니다. 참고

>  web3.fromWei(eth.getBalance(eth.accounts[0], "ether"));
"0"

4. 채굴 시작하기
