ethereum cold wallet 생성하기

ethereum cold wallet 생성하기

 

1. go언어 설치하기

2. 환경 설정 및 설치

hacker@ubuntu:/usr/local/go$ ls
api  AUTHORS  bin  blog  CONTRIBUTING.md  CONTRIBUTORS  
hacker@ubuntu:/usr/local/go$ 
hacker@ubuntu:/usr/local/go$ 
hacker@ubuntu:/usr/local/go$ export PATH=$PATH:/usr/local/go/bin
hacker@ubuntu:/usr/local/go$ export GOPATH=/usr/local/go


git clone https://github.com/vkobel/ethereum-generate-wallet.git
pip install ecdsa
pip install pysha3 

* SHA3sum 설치가 잘 안되므로 ethereum-generate-wallet안에 
 ./ethereum-wallet-generator.sh 이용하여 private key, public key를 생성하고
go-ethereum으로 address값을 구한다.

git clone https://github.com/ethereum/go-ethereum.git
make all
