Based on Onion Monero Blockchain Explorer
Testnet version:
- http://testnet-explorer.bit.tube/ - Official BitTube Testnet Block Explorer.
The key features of the BitTube Blockchain Explorer are:
- no cookies, no web analytics trackers, no images,
- by default no JavaScript, but can be enabled for client side decoding and proving transactions,
- open sourced,
- made fully in C++,
- showing encrypted payments ID,
- showing ring signatures,
- showing transaction extra field,
- showing public components of BitTube addresses,
- decoding which outputs and mixins belong to the given BitTube address and viewkey,
- can prove that you send BitTube to someone,
- detailed information about ring members, such as, their age, timescale and their ring sizes,
- showing number of amount output indices,
- support BitTube testnet and stagnet networks,
- 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,
- decoding outputs and proving txs sent to sub-address.
Download and compile recent BitTube into your home folder:
# first install BitTube 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 libsodium-dev libhidapi-dev libhidapi-libusb0
# go to home folder
cd ~
git clone --recursive https://github.com/ipbc-dev/bittube-coin.git bittube
cd bittube/
USE_SINGLE_BUILDDIR=1 make
Once the BitTube is compiled, the explorer can be downloaded and compiled as follows:
# go to home folder if still in ~/bittube
cd ~
# download the source code
git clone https://github.com/ipbc-dev/bittube-blockchain-explorer.git
# enter the downloaded sourced code folder
cd bittube-blockchain-explorer
# make a build folder and enter it
mkdir build && cd build
# create the makefile
cmake ..
# alternatively you can use: cmake -DBITTUBE_DIR=/path/to/bittube_folder ..
# if BitTube is not in ~/bittube
#
# also can build with ASAN (sanitizers), for example
# cmake -DSANITIZE_ADDRESS=On ..
# compile
make
To run it:
./bittube-blockchain-explorer
By default it will look for blockchain in its default location i.e., ~/.bittube/lmdb
.
You can use -b
option if its in different location.
For example:
./bittube-blockchain-explorer -b /home/mwo/non-default-bittube-location/lmdb/
Example output:
[mwo@arch bittube-blockchain-explorer]$ ./bittube-blockchain-explorer

# for mainnet explorer
alias bittube-blockchain-explorer-mainnet='~/bittube-blockchain-explorer/build/bittube-blockchain-explorer --port 8081 --testnet-url "http://139.162.32.245:8082" --enable-pusher --enable-emission-monitor'
# for testnet explorer
alias bittube-blockchain-explorer-testnet='~/bittube-blockchain-explorer/build/bittube-blockchain-explorer -t --port 8082 --mainnet-url "http://139.162.32.245:8081" --enable-pusher --enable-emission-monitor'
These are aliases similar to those used for http://139.162.32.245:8081/ and http://139.162.32.245:8082/, respectively.
Obtaining current BitTube emission amount is not straight forward. Thus, by default it is
disabled. To enable it use --enable-emission-monitor
flag, e.g.,
bittube-blockchain-explorer --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 ~/.bittube/lmdb/emission_amount.txt
. For testnet or stagenet networks,
it is ~/.bittube/testnet/lmdb/emission_amount.txt
or ~/.bittube/stagenet/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 ~/.bittube/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, testnet and stagenet. 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., :
BitTube emission (fees) is 14485540.430 (52545.373) as of 1313448 block
The values given, can be checked using BitTube 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, decoding and proving tx's outputs are done on the server side. To do this on the client side (private view and tx keys are not send to the server) JavaScript-based decoding can be enabled:
bittube-blockchain-explorer --enable-js
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 bittube-blockchain-explorer
in the following way:
./bittube-blockchain-explorer --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.
By default the api is disabled. To enable it, use --enable-json-api
flag, e.g.,
./bittube-blockchain-explorer --enable-json-api

For txprove=0
we check which outputs belong to given address and corresponding viewkey.
For txprove=1
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,
i.e., viewkey=<tx_private_key>

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 BitTube.
curl -w "\n" -X GET "http://139.162.32.245:8081/api/rawblock/1293257"

Return raw json tx data, as represented in BitTube.
curl -w "\n" -X GET "http://139.162.32.245:8081/api/rawtransaction/6093260dbe79fd6277694d14789dc8718f1bd54457df8bab338c2efa3bb0f03d"
