RE: Claimed.
It's easy to make this bot. It's very difficult to harden (secure) a bot. I've made several bots that could do what you ask. How long will they last? Depends on how secure the system is you put them on. All 3 bots I've created in the last month were hacked, although I did absolutely nothing to harden the system I put them on. They were just a test of the Piston code. I assume there's a security flaw in the Steem-Piston Python code that was developed by @xeroc. If you're OK with this, I can create a bot for you in a couple of days. I am not intersted in working for a bid, so if you're bidding me against others I am not interested in this project. I'm not going to build a bot only to find someone else's was picked and I did all that work for nothing. If this sounds good, you can email me at artopium at gmail as I do not care to have a steemit.chat account. ~Mike
"A couple of days" just refers to development time. Expect it to be more like a couple weeks for QA (quality assurance).
How were they hacked? Using the blockchain as the intermediary means you only have to trust your RPC endpoints, so unless you were giving people direct access to the server you were running them against I can't think of how. Though I'd be interested to know if I've overlooked something.
I'm not sure. I just know I ran the bots on a virtual server running ubuntu 16.04. While leaving the bots idle, while I was coding, not much happened. As soon as I left them to run on their own, they each ran for about 2 to 3 hours then would stop. When I checked on them the servers were either hit with DDOS, or in one instance someone actually got into the system as I could see a rogue connection on a udp port. Instead of trying to figure out how it happened I just destroyed the servers since it was just an experiment anyway. Since I spin up Ubuntu servers all the time, and since they usually don't get hacked that fast, I assume that it might have something to do either with the Piston code itself, or the activity from the server to the blockchain was enough to attract the attention of outsiders. My only point in all of this is that it would take me about a day to write the code for the bot. But if I'm expected to serve the bot as well, then it would take me much longer to ensure that the server was secure. If @berniesanders already has a server in mind to run the bot code on, then I will gladly code the bot. If not, I'm a little more hesitant as it mean debugging the piston code which I'm rather too unfamiliar with to do this in a timely manner.
can you plz guide me hot to make a bot.. i want to learn .. can you make a step by step video or something or somewhere frm where i can get the knowledge. thanks in advance
