 1 | Simple Block Explorer
 2 | =====================================
 3 | 
 4 | A trivial block explorer written in a single PHP file.
 5 | 
 6 | Demo
 7 | -------
 8 | https://bitcoin.jonasschnelli.ch/explorer/
 9 | 
10 | Features
11 | -------
12 | * Only requires Bitcoin Core (no additional index)
13 | * Does UTXO-set lookups
14 | * Can scan UTXO-set for address balances
15 | * Can scan blockfilters to create a transaction history of given address
16 | 
17 | Install
18 | -------
19 | * Place the `index.php` script into a php enabled http docs directory
20 | * Run Bitcoin Core with txindex and blockfilters `-txindex -blockfilterindex`
21 | * Edit the index.php config section
22 | 
23 | Nice links
24 | -------
25 | 
26 | Use `mod_rewrite` use a propper URL scheme (/block/<hash>), etc.
27 | Apache users can place a `.htaccess` file into the same folder as the PHP script.
28 | 
29 | ```
