# Onion Monero Blockchain Explor er
# Onion Monero Prov er
Curently available Monero blockchain explorer websites have several limitations which are of special importance to privacy-oriented users:
Currently, to prove to someone that you send them some monero, you can use this: [checktx ](http://xmr.llcoins.net/checktx.html ). Altought its useful, it is limited
in that it:
- they use JavaScript,
- have images which might be used for [cookieless tracking ](http://lucb1e.com/rp/cookielesscookies/ ),
- track users activates through google analytics,
- are closed sourced,
- are not available as hidden services,
- provide only basic search capabilities,
- can't identify users outputs based on provided Monero address and viewkey.
- uses JavaScript and
- not available as hidden services.
In this example, these limitations are addressed by development of
an Onion Monero Blockchain Explor er. The example not only shows how to use Monero C++ libraries, but also demonstrates how to use:
an Onion Monero Prover. The example 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

## Onion Monero Blockchain Explorer features
The key features of the Onion Monero Blockchain Explorer are
- available as a hidden service,
- no javascript, no cookies, no web analytics trackers, no images,
- open sourced,
- made fully in C++,
- the only explorer showing encrypted payments ID,
- the only explorer with the ability to search by encrypted payments ID, tx public
keys, stealth addresses, input key images,
output amount index and its amount,
- the only explorer showing ring signatures,
- the only explorer showing transaction extra field,
- the only explorer showing public components of Monero addresses,
- the only explorer that can show which outputs belong to the given Monero address and viewkey,
- the only explorer showing detailed information about mixins, such as, mixins'
age, timescale, mixin of mixins,
- the only explorer showing number of amount output indices.
## Prerequisite
Everything here was done and tested using Monero 0.9.4 on Ubuntu 16.04 x86_64.
