Something boring but important is happening on Bitcoin. The share of transactions using P2WPKH inputs, the native SegWit format that makes Bitcoin cheaper and faster to use, has climbed from roughly 55% to 75.7% in just a few months.
No protocol upgrade forced this. Users and services simply kept updating their software, one wallet at a time, until the network quietly crossed a threshold that makes the old way of transacting look increasingly obsolete.
What P2WPKH actually means (and why you should care)
Bitcoin transactions come in different “flavors” depending on how they structure their data. P2WPKH, short for Pay-to-Witness-Public-Key-Hash, is the native Segregated Witness format that was introduced when SegWit activated in August 2017 via a soft fork at block 481,824. It was standardized under BIP-84 and uses Bech32 addresses, the ones that start with “bc1q.”
P2WPKH inputs average around 27 virtual bytes for witness data. That translates to roughly a 38% size reduction compared to legacy formats for a typical transaction.
