<p>There currently exists no native address format for witness outputs, so the answer for P2WPKH and P2WSH is simply: you can't, and shouldn't.

Still ongoing? I want to know the latest trend. Is P2SH wrapper the defacto standard now? Seems bit142 is still deferred. https://github.com/bitcoin/bips/blob/master/bip-0142.mediawiki

BIP173 replaces it. It will take a long time to be adopted, however, so initially I expect segwit transfers to use the P2SH wrapper.

Nitpick: there's a checksum for the address in P2PK/P2PKH/P2SH. https://en.bitcoin.it/wiki/Technical_background_of_version_1_Bitcoin_addresses

Yes, thank you. To clarify for anyone reading this, it should be `base58('00' + hash160 + checksum)`

# How to get addresses from scriptPubKey in segwit transactions?

(Asked by: username_0 on 2016-11-12)

I'm running through raw transaction data, and I'd like to be able to gather addresses (where possible).

So far, I've made this diagram to help me understand when it's possible to figure out addresses from the `scriptPubKey` of each **output**:

[![enter image description here](https://i.sstatic.net/P7TvJ.png)](https://i.sstatic.net/P7TvJ.png)

However, as you can see, I'm not sure how I can work out an address from a **P2WSH**.

Is it possible to get addresses from the `scriptPubKey` alone, or can I only get them when the witness is revealed when the output has been spent? (as shown here):

```
witness:      0 <signature1> <1 <pubkey1> <pubkey2> 2 CHECKMULTISIG>
scriptSig:    (empty)
scriptPubKey: 0 <32-byte-hash>
              (0x0020{32-byte-hash})

```

There currently exists no native address format for witness outputs, so the answer for P2WPKH and P2WSH is simply: you can't, and shouldn't.

However, most segwit outputs initially will use the P2SH wrapper (resulting in P2SH-P2WPKH or P2SH-P2WSH programs), which just look like (and behave like) P2SH addresses.

A new native segwit address format is proposed in <https://github.com/bitcoin/bips/blob/master/bip-0173.mediawiki>. That can only be used when both the receiver and sender software support it however.

I assembled this picure with the top ten PKscripts I found somewhere on a webpage... don't find the link. I'd also want to extend it by segwit outputs. I can share the "graphml" file if desired.
