+Powers of Tau Operational Write-up
+==================================
+
+Round: 17
+
+Date: 2017-11-24
+
+Name: Wei Tang

+Location: Zhuhai, China
+
+Response (blake2b):
+
+	ee46b594 f06b0dd3 64af6fc1 936ac464
+	f62fc776 f6763ce1 1404c328 b1f64a95

+
+Procedure
+=========
+
+I downloaded the challenge file from an Amazon S3 bucket set up by
+Sean Bowe. I compiled the compute program using a nightly version of
+Rust, disabled network connection, and then generated a response. This
+is done on a laptop running NixOS 18.03.git.8f8bccf73e (Impala). I
+uploaded the response to the same Amazon S3 bucket.
+
+Side Channel Defenses
+=====================
+
+Entropy source: several random Lojban words picked up in an
+undisclosed way.
+
+Physical/electronic monitoring: All steps performed from the comfort
+of my living room.
+
+I have no intention to destroy the compute node.
