Information Gathering

This post is going to be different in a few ways. Instead of going in and looking at making a steemit bot as is we are going to take a step back and look at how to do certain things like get information about an account or blockchain. For instance you can use:

from steem import Steem
s = Steem()
s.get_account('ned')

and you will get an output like this:

{'id': 497, 'name': 'ned', 'owner': {'weight_threshold': 1, 'account_auths': [], 'key_auths': [['STM71f6yWztimJuREVyyMXNqAVbx1FzPVW6LLXNoQ35dHwKuszmHX', 1]]}, 'active': {'weight_threshold': 1, 'account_auths': [], 'key_auths': [['STM7RyrKG8e3fUtPD2JH9AB8K1p7ypsLUDPMuiV1gtD4DbNuk6nBw', 1]]}, 'posting': {'weight_threshold': 1, 'account_auths': [], 'key_auths': [['STM6rHZiAKHZS19RSJuRmn3mdukj95AYgUNFCEgnm8jhZE3rcH72P', 1]]}, 'memo_key': 'STM6sUWU9dtss1N8m7tQfUt7PacNHACrt3jBZNtkYkMMBv3e4CH3p', 'json_metadata': '{"profile":{"profile_image":"https://pbs.twimg.com/profile_images/915596048428621825/_nuXsMTT.jpg","location":"Welcome to Steemit!","name":"ned","cover_image":"https://steemit.com/images/steemit.png","website":"https://smt.steem.io"}}', 'proxy': '', 'last_owner_update': '2017-03-02T00:20:39', 'last_account_update': '2018-01-25T22:26:24', 'created': '2016-03-31T14:21:45', 'mined': False, 'owner_challenged': False, 'active_challenged': False, 'last_owner_proved': '1970-01-01T00:00:00', 'last_active_proved': '1970-01-01T00:00:00', 'recovery_account': 'steem', 'last_account_recovery': '1970-01-01T00:00:00', 'reset_account': 'null', 'comment_count': 0, 'lifetime_vote_count': 0, 'post_count': 741, 'can_vote': True, 'voting_power': 10000, 'last_vote_time': '2018-02-05T22:42:03', 'balance': '111865.316 STEEM', 'savings_balance': '0.000 STEEM', 'sbd_balance': '5750.349 SBD', 'sbd_seconds': '3112990678638', 'sbd_seconds_last_update': '2018-02-07T04:04:30', 'sbd_last_interest_payment': '2018-01-31T21:41:27', 'savings_sbd_balance': '1249.949 SBD', 'savings_sbd_seconds': '0', 'savings_sbd_seconds_last_update': '2017-01-01T19:19:27', 'savings_sbd_last_interest_payment': '2017-01-01T19:19:27', 'savings_withdraw_requests': 0, 'reward_sbd_balance': '767.164 SBD', 'reward_steem_balance': '0.000 STEEM', 'reward_vesting_balance': '8048624.290132 VESTS', 'reward_vesting_steem': '3918.633 STEEM', 'vesting_shares': '7344140982.676874 VESTS', 'delegated_vesting_shares': '5555196185.233783 VESTS', 'received_vesting_shares': '0.000000 VESTS', 'vesting_withdraw_rate': '0.000000 VESTS', 'next_vesting_withdrawal': '1969-12-31T23:59:59', 'withdrawn': 0, 'to_withdraw': 0, 'withdraw_routes': 0, 'curation_rewards': 734552321, 'posting_rewards': 8476465, 'proxied_vsf_votes': ['121114137626959', 0, 0, 0], 'witnesses_voted_for': 0, 'average_bandwidth': '17558214870', 'lifetime_bandwidth': '3739769000000', 'last_bandwidth_update': '2018-02-07T22:55:57', 'average_market_bandwidth': 2599317261, 'lifetime_market_bandwidth': '118810000000', 'last_market_bandwidth_update': '2018-01-29T03:31:21', 'last_post': '2018-02-07T22:55:57', 'last_root_post': '2017-11-08T00:11:30', 'vesting_balance': '0.000 STEEM', 'reputation': '78828263679953', 'transfer_history': [], 'market_history': [], 'post_history': [], 'vote_history': [], 'other_history': [], 'witness_votes': [], 'tags_usage': [], 'guest_bloggers': []}

Now first thing I would suggest doing is modifying the program from the previous post to get something a little more practical for output.

from steem import Steem

s = Steem()
follow = str(input("Enter who to follow: "))

action = str(s.get_account(follow))

def nl(nt):
    print('\n', end='')
    for i in range(0,nt):
        print("\t", end='')

def pnjson(js):
    ntabs = 0
    for i in range(0, len(js)):
        if js[i]=='{':
            print(js[i], end='')
            ntabs = ntabs+1
            nl(ntabs)
        elif js[i]=='[':
            print(js[i], end='')
            ntabs = ntabs+1
            nl(ntabs)
        elif js[i]==']':
            ntabs = ntabs-1
            nl(ntabs)
            print(js[i], end='')
        elif js[i]=='}':
            ntabs = ntabs-1
            nl(ntabs)
            print(js[i], end='')
        elif js[i]==',':
            print(js[i], end='')
            nl(ntabs)
        else:
            print(js[i], end='')
    nl(0)

pnjson(str(action))

This has been cut short because it was really long
For full print out, do it yourself.

As you can see this makes the account data a lot easier to read. So now we have a program that can look at the public account data (which by the way you could just go to the steemd for that persons account and get the same information) but if we truly want to stalk them then we may want it to be more specific, say looking at specific information like the balance of steem and sbd that they have.

Monitor.py

from steem import Steem

s = Steem()

account = str(input("Enter Account to Monitor: "))

print("Steem Balance: " + str(s.get_account(account)['balance']))
print("SBD Balance: " + str(s.get_account(account)['sbd_balance']))
print("Savings Steem Balance: " + str(s.get_account(account)['savings_balance']))
print("Savings SBD Balance: " + str(s.get_account(account)['savings_sbd_balance']))
print("Reward Steem: " + str(s.get_account(account)['reward_vesting_steem']))
print("Reward SBD: " + str(s.get_account(account)['reward_sbd_balance']))

Output

kryzsec@kryzsec-a101:~/ssb$ python monitor.py 
Enter Account to Monitor: ned
Steem Balance: 111865.316 STEEM
SBD Balance: 5750.349 SBD
Savings Steem Balance: 0.000 STEEM
Savings SBD Balance: 1249.949 SBD
Reward Steem: 3918.633 STEEM
Reward SBD: 767.164 SBD

If you want to modify it to look for different information than just add more print lines and print out the output. You have, on the left, a complete output of an account that you can look at the data of. This is, in no way, an attempt to convince everyone to go out and start stalking people, its just if you are reading tutorials on how to make a bot then, depending on what type of bot yo are making, it might be beneficial to know this kind of stuff. So, how can we use the information in this post to create a bot? How about a bot that automatically withdraws funds?

Warning this program will require the use of a private active key (I am pretty certain) and thus should only be done as is if you know what you are doing. Best bet is you should use the cli-wallet to store your keys and use the keys from the wallet instead as it will keep your keys encrypted and safe in case of malware or otherwise. Remember, do not share your private keys with anyone!

from steem import Steem
import time
Account = str(input("Enter account name: "))
pak = str(input("Enter the associating private active key: "))
st = int(input("How often do you want to check? (1 is every block, 2 is ever 2nd block): "))
if st<1:
    st = 1
s = Steem(keys=pak)
while True:
    SBD = s.get_account(Account)['reward_sbd_balance']
    STEEM = s.get_account(Account)['reward_vesting_steem']
    if SBD!='0.000 SBD' or STEEM!='0.000 STEEM':
        print("Collecting " + SBD + " " + STEEM)
        s.claim_reward_balance(account=Account)
    time.sleep(3*st)

Since a new block should be made every 3 seconds we can change how often we check (say to every 30 minutes) by changing the number that we input. To use this to check once every hour then we would input the following:

Enter account name: kryzsec
Enter the associating private active key: P5privatepostingkeyhere462
How often do you want to check? (1 is every block, 2 is ever 2nd block): 1200
Collecting 0.010 SBD 0.003 STEEM

Since 1 hour has 3600 seconds (60 seconds in 1 minute and 60 seconds in 1 hour, i.e. 60*60=3600) and since a new block is minted every 3 seconds we would divide that by 3 to get the number of blocks that we want to have been made before we attempt to check. This can however be used for a lot more things. Maybe you want to write a bot that will go through and see whom all votes for a specific witness or you want to go and write a bot that searches for whom has the mosts vests to try and figure out whom the richest steem users are. I do not know what you would want to do but this will allow you to do a lot of interesting things.
