RPC Ace is a simple alternative block explorer written in PHP. It does not generate a database, and it interacts with block chains entirely via RPC, either against a locally running wallet/daemon or remotely over the Internet.

A database-less explorer has a few drawbacks - most notably, RPC Ace cannot keep track of addresses or total coins generated, and as it uses RPC calls to parse blocks a transaction-heavy block chain (such as Bitcoin) can incur heavy CPU usage and/or long page generation times. RPC Ace's primary use is quick access to oversight of a block chain; for in-depth needs it's recommended to run a tallying explorer such as Abe.

RPC Ace should work with any block chain regardless of what proof-of-work algorithm is used, and has been tested to work with Bitcoin, Litecoin, Dogecoin, Solcoin and a few other block chains, but as it's still at an early stage it may contain bugs. Version 0.6.5 introduced PoS support, which has been tested against a number of popular PoS block chains.

RPC Ace (and the extras) requires PHP version 5.4 or later, with CURL and JSON support enabled.

Place rpcace.php and easybitcoin.php (get it here) together in your web directory. The first few lines of rpcace.php contain all of its configurable parameters:

$rpcHost = '127.0.0.1';                  // Host/IP for the daemon
$rpcPort = 12345;                        // RPC port for the daemon
$rpcUser = 'username';                   // 'rpcuser' from the coin's .conf
$rpcPass = 'password';                   // 'rpcpassword' from the coin's .conf
$coinName = 'Somecoin';                  // Coin name/title for the explorer
$coinHome = 'http://www.somecoin.org/';  // Coin website
$coinPoS = false;                        // Set to true for proof-of-stake coins
$numBlocksPerPage = 12;                  // Number of blocks to parse per page
$refreshTime = 180;                      // Seconds between automatic page refresh

To get accurate transaction values your block chain must be built with full transaction indexing from the start, by setting txindex=1 in the coin's .conf file.

tally.php generates a "rich list". Usage: configure user/pass/host/port in the beginning of the file, and then run from command line: php tally.php <output>. Accurate results require the block chain being built with full transaction indexing. Avoid storing tally.php in your web directory where users may run it remotely, as it can be very time- and CPU-consuming when parsing long block chains.

When finished parsing blocks, tally.php will output its progress to a file named RPCUSER-RPCPORT-tally.dat which will be used to resume operations next time tally.php runs in order to avoid having to start over from block 1 when updating a list. Aborting the script while running by pressing CTRL+C will also save the progress file for later use.
