+Powers of Tau Attestation
+
+Gibson Ashpool
+
+USA
+
+
+Purchased four core2duo PC's with cash from someone on Craigslist over a year ago for another project but they have been collecting dust for months now so figured they are good candidates for powers of tau.  
+
+TAU machine specs:
+
+Dell Optiplex 330
+
+Intel Core2duo
+
+2GB ddr2 Kensington RAM
+
+80GB HDD
+
+
+To start preparing I wiped the HDD with DBAN eraser. Ran memtests via live CD and then installed Lubuntu 16.04. 
+
+
+Ran following commands via terminal:
+
+> sudo curl -sSF https://static.rust-lang.org/rustup.sh | sh
+
+> sudo apt-get install git
+
+I downloaded the challenge file on a seperate PC, then transferred the challenge file to the compute PC via USB stick.
+
+> git clone https://github.com/ebfull/powersoftau
+
+Plugged in USB stick and copied challenge file into powersoftau directory
+
+> cd powersoftau
+
+> cargo run --release --bin compute
+
+It ran for a short time then when prompted for entropy, added long random string of text. I then asked my daughter to enter random keys while I didnt look, to which she replied "Really? Just press the keys?" and I replied "Press as many as you want, just dont press the enter key" she then pressed random keys for about 15 seconds and when she was done I instructed her to hit the enter key. I then turned back to the terminal to see "reading challenge into memory, Computing, this could take awhile" in the terminal. It was getting late so I put her to bed, grabbed a beer and watched TV, checking back every 15mins or so.
+
+Compute took almost 2hrs

+
+
+Copyed response file to USB stick and transferred to other PC, then uploaded response file to AWS server
+
+Powered down PC, removed two RAM sticks and HDD. Destroyed RAM and HDD with power tools.
+
+I then performed full format on USB stick.
+
+Uploaded images of process to imgur https://imgur.com/a/O7i0L (bonus points if you can spot stealth cat)
