 The new Bitcoin address format defined is for the Pay-to-Witness-Public-Key-Hash (P2WPKH) and Pay-to-Witness-Script-Hash (P2WSH) transaction described in segregated witness soft fork (BIP141). The scriptPubKey is an OP_0 followed by a push of 20-byte-hash (P2WPKH) or 32-byte hash (P2WSH).

+BIP141 defines 2 ways of encoding a "witness program", a data push of 2 to 32 bytes:
 
 * A native witness program output is a scriptPubKey with a push of version byte followed by a push of witness program, and nothing else;
 * Segwit-in-P2SH is a BIP16 P2SH redeemScript with a push of version byte followed by a push of witness program, while the scriptPubKey looks like a normal P2SH output.
 
-As the BIP13 P2SH address has been defined in 2012, using segwit-in-P2SH allows most existing wallets to pay a segwit-compatible wallet without any upgrade. However, this method requires more block space and is only a short-term solution to make the transition smoother. Eventually, all users are expected to use the more efficient native witness program as the primary payment method.

 However, none of these are as widely adopted as the suboptimal base-58 scriptPubKey template addresses, which is still a standard for the whole eco-system, from wallets, block explorers, merchants, exchanges, to end users. It is believed that the proposed P2WPKH and P2WSH address format is the easiest way for wallets and services to adopt native witness program, which is particularly important in the context of scaling the capacity of the blockchain.
 
-While P2WPKH address is specific for simple payment to a single public key, P2WSH address allows arbitrarily complex segwit transactions, resemble to the BIP13 P2SH address.
