A simple PHP block explorer for browsing transactions and claims on the [LBRY](https://lbry.com) blockchain. The explorer was developed using CakePHP which is a model-view-controller (MVC) PHP framework.
## Requirements
## Installation
There are some prerequisites that need to be installed before the explorer can be accessed.
* Web server - Apache, caddy or nginx
* [lbrycrd](https://github.com/lbryio/lbrycrd) with txindex turned on
* MariaDB 10.2 or higher
* Redis Server (optional, only required for the CakePHP redis cache engine, or to run `forevermempool`)
* PHP 7.4 or higher
* PHP 7.2 or higher
* php-fpm
* [igbinary extension](https://github.com/igbinary/igbinary)
* [phpredis extension](https://github.com/phpredis/phpredis)
* composer (PHP package manager)
on ubuntu you may use this to install php requirements
```bash
sudo apt install php7.4-gmp php7.4-intl php7.4-mbstring php7.4-mysql php7.4-bcmath php7.4-gd
```
### Installation steps
* Clone the Github repository. `git clone https://github.com/lbryio/block-explorer`
* Create a MariaDB database using the DDL found in `block-explorer/sql/lbryexplorer.ddl.sql`
