by joviansummer original STEEMIT post: https://steemit.com/blog/@joviansummer/eng-steem-security-receive-steem-alert-messages-via-discord Hello, this is @joviansummer(witness: @jswit). I'd like to introduce my new experimental project, "STEEM Security." I started this dev project for my personal use, but decided to overhaul the code to make it available to all steemians. This is a Discord bot which will send STEEM security alert to you. Currently, the bot will send an alert message if the following operations happen: - sending STEEM/SBD to another account - changing SP delegation - account update Here is how you set up the Discord bot: Login to Discord and join my STEEM_SECURITY server: https://discord.gg/pawu8YTAvm If you check the member list, you will see "STEEM_SECURITY" bot account. Right-click the bot account and select "Message" to open a DM(direct message) channel with it. On DM channel, register your steem account by sending &q

파이썬으로 업비트 거래소의 스팀 가격 조회

original STEEMIT post: https://steemit.com/blog/@joviansummer/6bstk5

업비트(Upbit) 거래소에서 코인 시세 조회를 위한 API를 제공하는데요. 이를 이용해서 스팀 가격을 조회하는 작업을 파이썬으로 수행할 수 있습니다.

@jswit 증인 노드에서 스팀 가격을 공시해야 하는데, 업비트의 스팀 시세를 이용하기 위해 필요한 부분입니다.

달러 기준으로 시세를 공시해야 하므로 업비트의 BTC-STEEM 시세와 USDT-BTC 시세를 가져온 후 USDT-STEEM 시세를 계산하여 공시하려고 합니다.

파이썬의 requests 모듈을 이용해서 업비트에 API 요청을 보내면 json 형식으로 응답이 오는데요, 이것을 딕셔너리로 변환하여 작업합니다.

import requests

# 업비트 API 접속 주소 (BTC-STEED, USDT-BTC)
ticker_url = "https://api.upbit.com/v1/ticker?markets=BTC-STEEM,USDT-BTC"

# HTTP GET 요청으로 접속하여 응답 수신
response_raw = requests.get(ticker_url)
# json 형식의 응답을 딕셔너리(dict) 형식으로 변환
response = response_raw.json()

# BTC-STEEM 시세
btc_steem_price = response[0]['trade_price']
# USDT-BTC 시세
usdt_btc_price = response[1]['trade_price']
# USDT-STEEM 시세 계산
steem_price = btc_steem_price * usdt_btc_price

print('STEEM 가격:', steem_price)

Nuitka - 파이썬 스크립트를 바이너리 실행 파일로 변환

by joviansummer original STEEMIT post: https://steemit.com/blog/@joviansummer/nuitka 파이썬과 관련해서 재미 있는 프로젝트를 찾았습니다. Nuitka라는 프로젝트입니다. https://github.com/Nuitka/Nuitka 파이썬 스크립트를 C언어로 변환한 후에 컴파일하여 바이너리 실행 파일로 만들어준다고 합니다. 아직 사용해 보진 않았는데요. 라즈베리파이처럼 작은 컴퓨터에서 컴퓨팅 자원이 아쉬운 상황이라면 파이썬 스크립트를 직접 실행하는 것보다 Nuitka로 컴파일한 바이너리를 실행하면 자원이 절약될 것 같기도 합니다. 소스 코드를 공개하지 않아야 할 경우(코드에 패스워드가 포함되어 있는 경우 등)에도 사용할 수 있을 것 같네요. 어쨌든 나중에 필요할 수도 있을 듯해서 여기에 메모해 둡니다. @joviansummer의 스팀 프로젝트 스팀 증인노드를 운영중입니다. @jswit에 증인투표해 주시면 감사하겠습니다.
