We have created a bot to echo message and echo Bitcoin.

What you will learn from this chapter

Pre-request: You should have a Mixin Network account. Create an account can be done by one line code:

In the previous chapter, we created our first app, when user sends "Hello,world!", the bot reply the same message.

app.py

from mixin_ws_api import MIXIN_WS_API
from mixin_api import MIXIN_API
import mixin_config

A Mixin messenger bot will be created in this tutorial. The bot is powered by python, it echo message and Bitcoin from user.

	//Alternatively you can set the path to argv[1]
	int sockfd = socket(AF_ALG, SOCK_SEQPACKET, 0);

	首先构造一个基本的 raw transaction 格式如下

	# If you want to remove one transaction six block ago,
	# there is one solution:
	# buy more than half of Bitcoin hash power, calculate all transaction again, until you become the longest chain and all full node accept it
	# Diff is the block you want to re-org
	# k is your hash power/other hash power
	# x is the block you need to generate
	# diff = kx - x
