The source code used for the monerovexplorer.com website. An implementation of a MoneroV blockchain explorer. Currently connected to the upcoming monerov daemon and showcases the MoneroV 1:10 blockchain ratio diffrence for all previous and live transactions on Monero mainnet.
- no javascript, no cookies, no web analytics trackers, no images,
- open sourced,
- made fully in C++,
- showing encrypted payments ID,
- showing ring signatures,
- showing transaction extra field,
- showing public components of MoneroV addresses,
- decoding which outputs and mixins belong to the given MoneroV address and viewkey,
- can prove that you sent MoneroV (XMV) to someone,
- detailed information about mixins, such as, mixins' age, timescale, mixin of mixins,
- showing number of amount output indices,
- tx checker and pusher for online pushing of transactions,
- estimate possible spendings based on address and viewkey,
- can provide total amount of all miner fees.
- decoding encrypted payment id.
Compilation on Ubuntu 16.04 (Will only be available When the monerov daemon is released to the public)
Download and compile recent MoneroV into your home folder:
# first install monerov's dependecines
sudo apt update
sudo apt install git build-essential cmake libboost-all-dev miniupnpc libunbound-dev graphviz doxygen libunwind8-dev pkg-config libssl-dev libcurl4-openssl-dev libgtest-dev libreadline-dev libzmq3-dev
# go to home folder
cd ~
# clone the monerov daemon (when it's publicly available)
git clone https://github.com/monerov/monerov
cd monerov/
make
Once MoneroV compiles, the explorer can be downloaded and compiled as follows:
# go to home folder if you're still in ~/monerov
cd ~
# download the source code
git clone https://github.com/monerov/monerov-explorer.git
# enter the downloaded sourced code folder
cd monerov-explorer
# make a build folder and enter it
mkdir build && cd build
# create the makefile
cmake ..
# altearnatively can use: cmake -DMONERO_DIR=/path/to/monerov_folder ..
# if monerov is not in ~/monerov
# compile
make
When compilation finishes executable xmrblocks
should be created. Before running
please make sure that ~/Downloads
folder exists and is writable.
Time zone library that explorer is using, puts there
its database of time zone offsets
To run it:
./xmrblocks
By default it will look for blockchain in its default location i.e., ~/.monerov/lmdb
.
You can use --bc-path
option if its in different location.
Example output:

# for mainnet explorer
alias xmrblocksmainnet='~/monerov-explorer/build/xmrblocks --port 8081 --testnet-url "http://122.112.5.45:8082" --enable-pusher --enable-emission-monitor'
# for testnet explorer

Obtaining current MoneroV emission amount is not straight forward. Thus, by default it is
disabled. To enable it use --enable-emission-monitor
flag, e.g.,
xmrblocks --enable-emission-monitor
This flag will enable emission monitoring thread. When started, the thread
will initially scan the entire blockchain, and calculate the cumulative emission based on each block.
Since it is a separate thread, the explorer will work as usual during this time.
Every 10000 blocks, the thread will save current emission in a file, by default,
in ~/.monerov/lmdb/emission_amount.txt
. For testnet network,
it is ~/.monerov/testnet/lmdb/emission_amount.txt
. This file is used so that we don't
need to rescan entire blockchain whenever the explorer is restarted. When the
explorer restarts, the thread will first check if ~/.monerov/lmdb/emission_amount.txt
is present, read its values, and continue from there if possible. Subsequently, only the initial
use of the tread is time consuming. Once the thread scans the entire blockchain, it updates
the emission amount using new blocks as they come. Since the explorer writes this file, there can
be only one instance of it running for mainnet and testnet. Thus, for example, you cant have
two explorers for mainnet
running at the same time, as they will be trying to write and read the same file at the same time,
leading to unexpected results. Off course having one instance for mainnet and one instance for testnet
is fine, as they write to different files.
When the emission monitor is enabled, information about current emission of coinbase and fees is displayed on the front page, e.g., :
MoneroV emission (fees) is 144855404.30 (525453.73) as of 1313448 block
The values given, can be checked using MoneroV daemon's print_coinbase_tx_sum
command.
For example, for the above example: print_coinbase_tx_sum 0 1313449
.
To disable the monitor, simply restart the explorer without --enable-emission-monitor
flag.
By default, the explorer does not use ssl. But it has such a functionality.
As an example, you can generate your own ssl certificates as follows:
cd /tmp # example folder
openssl genrsa -out server.key 1024
openssl req -new -key server.key -out server.csr
openssl x509 -req -days 3650 -in server.csr -signkey server.key -out server.crt
Having the crt
and key
files, run xmrblocks
in the following way:
./xmrblocks --ssl-crt-file=/tmp/server.crt --ssl-key-file=/tmp/server.key
Note: Because we generated our own certificate, modern browsers will complain about it as they cant verify the signatures against any third party. So probably for any practical use need to have properly issued ssl certificates.
The explorer has JSON api. For the API, it uses conventions defined by JSend.

we use to prove to the recipient that we sent them founds.
For this, we use recipient's address and our tx private key as a viewkey value,

api number is store as uint32_t
. In this case 65536
represents
major version 1 and minor version 0.
In JavaScript to get these numbers, one can do as follows:
var api_major = response.data.api >> 16;
var api_minor = response.data.api & 0xffff;
Return raw json block data, as represented in MoneroV.
curl -w "\n" -X GET "http://122.112.5.45:8081/api/rawblock/1293257"
