 # Onion Monero Blockchain Explorer
+
+Two Monero blockchain explorer exist in the clearnet. Although useful,
+their limitations are that they use JavaScript, have images
+([might be used for coockless tracking](http://lucb1e.com/rp/cookielesscookies/)), use
+use google analytics, are not open sourced, and are not
+ available as hidden services. These things are of importance
+ for privacy-oriented users.
+
+ In this example, these limitations are addressed. Specifically,
+ an Onion Monero Blockchain Explorer is developed. It is build in C++,
+ and it not only shows how to use Monero C++ libraries, but also demonstrates how to
+ use:
+
+  - [crow](https://github.com/ipkn/crow) - C++ micro web framework
+  - [lmdb++](https://github.com/bendiken/lmdbxx) - C++ wrapper for the LMDB
+  - [mstch](https://github.com/no1msd/mstch) - C++ {{mustache}} templates
+  - [rapidjson](https://github.com/miloyip/rapidjson) - C++ JSON parser/generator
+
+
+
+# Onion Monero Blockchain Explorer features
+
+ - no javascript, no web analytics trackers, no images, i.e., no user tracking
+ - open source which allows everyone to check its source code, fork it, contribute
+ - made fully in C++ allowing for seamless integration with Monero
+ - does not use RPC calls, except to get mempool data, which improves its performance
