This Week's Auctions

Different mining pools sending out the same or a similar block template to miners is an indicator for proxy pooling. Knowing about proxy pools is important when discussing mining pool centralization. To find similarities between mining pool block templates, I compare the Merkle branches pools sent in the stratum jobs and calculate a similarity score. This shows pools with similar templates and allows building a relationship graph between the pools.

@Rsync25 stacked 375 sats posting https://cointelegraph.com/news/norway-town-hadsel-bitcoin-mining-noise-electricity-costs [3 comments]

It all starts with the SUN. These panels were purchased for about $30 a piece, a fraction of what new panels cost. I have 60 of them that are just for mining sats. Notice, there are no mounts, no ground wiring, no conduit. This is as basic as it gets. Panels thrown on the ground and wired together. Some day I will put elevate them a bit with some posts and get them at a better matched angle for better performance. I literally found this trailer abandoned in the middle of the desert. It was full of rats, rat shit, and other things. It was disgusting. No tires, full of holes, left to rot away. I took an axle off my other trailer, slapped it on, towed it up my hill. Cleaned it out, plugged the holes, painted it. Now it houses all the electrical and mining equipment. This cost me almost nothing but time. The internet for the miners and everything else I do online happens right here in my little cell phone wifi tower thingy. It has an old phone that is a 24/7 hotspot, $25 a month for unlimited data, then a little wifi repeater than makes that signal a wired signal, and a wifi router that serves about half of 40 acres. When there isn’t competing signals and blockages, wifi goes pretty far. From here I have a hard line feeding a switch in the mining shack to get the miners internet service when they are hard at work. I have 2 of PowMR All in one solar inverters about 5500watts a peice. They capture the solar, charge the batteries and run the miners. Awesome Value in Solar. We may live simply but we are smart. All the miners and inverters can be controlled with these smart outlets and relays. So i don’t have to do much work to keep things going. Miners go on and off with timers. I make adjustments for weather as needed. Lithium Iron Phosphate batteries are now cheaper than lead acid. And they last forever and perform WAY better. I love these things. I run 12V batteries in series of 4 to work with the 48v system. These basically act like a energy cache, take on the load when there is cloud cover and what not. And they do extend my mining day a bit. But my system is far too small to run the miners 24/7 This is the equipment that runs the small 3 panel setup to keep the wifi and my pi3 media server up 24/7. I do not have any subscription services, so the media server is awesome. Its my google drive, netflix, spotify, etc. So awesome to have And finally the miners. I have 6 x s19j pros. i bought them new about 4 years a go. They have been on grid and overclocked in the past. Now they are running at 1800 watts a piece, and take it nice and easy. Sleep all night. Work all day, unless its a cloudy nappy kind of day. Their names are Howard, Lester, Kenny, Danny, David, and Nathan. They are the best. They make sure everyday I have just a little more bitcoin than I had the day before. What more can a man ask for? Please share all of your questions and comments. Thanks for looking 💚 [100 comments]
