#Examples
Some examples are provided at the [examples](/examples) path. Here are some snippets:
## Address handling
Validating a Bitcoin address:
```
var Address = require('bitcore/Address').class();
var addr = new Address("1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa");
try {

## Monitoring Blocks and Transactions
```
var networks = require('bitcore/networks');
var Peer = require('bitcore/Peer').class();
var PeerManager = require('bitcore/PeerManager').createClass({
network: networks.livenet
});
var handleBlock = function(b) {
console.log('block received:', b);
};
var handleTx = function(b) {
console.log('block tx:', b);
};
var peerman = new PeerManager();
peerman.addPeer( new Peer('62.75.216.13',8333) );
peerman.addPeer( new Peer('62.75.253.91',8333) );
peerman.on('connection', function(conn) {
conn.on('block', handleBlock);
conn.on('tx', handleTx);
});
peerman.start();
```
PeerManager will emit the following events: 'version', 'verack', 'addr', 'getaddr', 'error' 'disconnect'; and will relay events like: 'tx', 'block', 'inv'. Please see [PeerManager.js](PeerManager.js), [Peer.js](Peer.js) and [Connection.js](Connection.js)
## Create and send a Transaction thought P2P

## RPC Client
```
var RpcClient = require('../RpcClient').class();
var config = {
protocol: 'http',
user: 'user',
pass: 'pass',
host: '127.0.0.1',
port: '18332',
};
var rpc = new RpcClient(config);
rpc.getBlock( hash, function(err, ret) {
console.log(err);
console.log(util.inspect(ret, { depth: 10} ));
});
```
Check the list of all supported RPC call at [RpcClient.js](RpcClient.js)
## Script Parsing
Gets an address strings from a ScriptPubKey Buffer
```
var Address = require('bitcore/Address').class();
var coinUtil= require('bitcore/util/util');
var getAddrStr = function(s) {
var addrStrs = [];
var type = s.classify();
var addr;
switch (type) {
case Script.TX_PUBKEY:
var chunk = s.captureOne();
addr = new Address(network.addressPubkey, coinUtil.sha256ripe160(chunk));
addrStrs.push(addr.toString());
break;
case Script.TX_PUBKEYHASH:
addr = new Address(network.addressPubkey, s.captureOne());
addrStrs.push(addr.toString());
break;
case Script.TX_SCRIPTHASH:
addr = new Address(network.addressScript, s.captureOne());
addrStrs.push(addr.toString());
break;
case Script.TX_MULTISIG:
var chunks = s.capture();
chunks.forEach(function(chunk) {
var a = new Address(network.addressPubkey, coinUtil.sha256ripe160(chunk));
addrStrs.push(a.toString());
});
break;
case Script.TX_UNKNOWN:
break;
}
return addrStrs;
};
var s = new Script(scriptBuffer);
console.log(getAddrStr(s);
