# Onion Monero Blockchain Explorer # 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
