From 42cb388167ef78f47a3a440eb651b6938c10f508 Mon Sep 17 00:00:00 2001 From: James O'Beirne Date: Mon, 7 Sep 2015 15:22:23 -0700 Subject: Add chainstate obfuscation to avoid spurious antivirus detection Adds an `obfuscate` parameter to `CLevelDBWrapper` and makes use of it for all new chainstate stores built via `CCoinsViewDB`. Also adds an `Xor` method to `CDataStream`.
