Compressed public keys are a more efficient serialization, so they correspond to a different address. Given a public key, you can determine the "compressed address" and the "uncompressed address", but not from just an address. Clients can only receive coins on compressed addresses if they support compressed public keys in the first place.

Compressed keys aren't yet supported anywhere else because that would be a protocol-breaking change. The advantage is mainly for the blockchain and the network, as transactions will be a bit smaller now. It's 33 bytes instead of 65, by the way. I have a problem understanding it : I have an uncompressed private key, I enter it in bitaddress. On one I have one million dollar, on the other 0. And they both come from the same private key. How does that make sense? Jus12 1, 1 1 gold badge 12 12 silver badges 24 24 bronze badges.

I hope this helps future readers contrast the two answers here. The quote is quite misleading. Hash function is applied twice. Akater hash applied twice is still a hash. Since it doesn't say which function Hash corresponds to, the quote is correct. I don't know which function is used, so maybe e. It may help to break the fields apart.
