SegWit-Native Adoption
Combined output share of all SegWit-native witness formats (P2WPKH + P2WSH + P2TR). Aggregate adoption of witness-based outputs since BIP141 (2017) and BIP341 Taproot (2021), measured at the output level.
What is it?
This metric sums the 1-week rolling shares of the three witness-based SegWit-native output formats: P2WPKH (single-signature, BIP141), P2WSH (multisig, BIP141), and P2TR (Taproot, BIP340-342). It measures the total share of created outputs using a SegWit-native format, as opposed to legacy formats (P2PKH, non-witness P2SH). It is the capstone of the output types family: an aggregate view of the network's migration to separated-witness formats.
How to read
The vertical axis is a percentage between 0 and 100. The curve starts near zero before SegWit activation (August 2017), then grows as P2WPKH then P2TR gain ground. A steep slope indicates rapid migration of new outputs to witness formats; a plateau indicates the structural residual share of legacy formats (P2PKH, P2SH-wrapped). It is the mirror of the P2PKH decline curve (#365).
Key zones
Pre-2017-08-24: near-zero zone (SegWit-native formats do not exist). P2WPKH expansion phase (2017-2021): rise driven by retail wallets and exchanges. Taproot phase (post-2021-11-14): P2TR adds a growing contribution. The closer the combined share approaches a ceiling, the smaller the residual legacy share (P2PKH + P2SH-wrapped) becomes.
What to observe
Compare this aggregate curve with the P2PKH decline curve (#365) - the two should evolve as mirrors (SegWit rise ↔ legacy decline). Also watch the decomposition: the combined share is dominated by P2WPKH (#367), with a growing P2TR contribution (#369-#371) and a stable P2WSH share (#368). An acceleration without a P2WPKH rise would indicate the new adoption wave favours Taproot.
Historical context
SegWit-native formats were introduced in two stages: BIP141 SegWit (24 August 2017) brought P2WPKH and P2WSH with the separated witness and fee discount; BIP340-342 Taproot (14 November 2021) added P2TR with Schnorr signatures. Aggregate adoption was accelerated by mempool congestion periods (2021, 2024 Ordinals) where the SegWit fee discount becomes economically decisive.
Expert notes
This metric measures the OUTPUT-level share (sum of P2WPKH + P2WSH + P2TR output shares), distinct from the prod metric `segwit-adoption-rate` which measures the percentage of SegWit TRANSACTIONS (transaction count dimension). Both readings are complementary: the output share reflects the composition of created UTXOs, the transaction rate reflects the share of transactions consuming at least one SegWit input. Note: P2SH-wrapped SegWit envelopes (included in P2SH #366) are NOT counted here - only native witness formats are aggregated.
Common mistakes to avoid
Do not confuse with the prod metric `segwit-adoption-rate` which counts SegWit TRANSACTIONS (transaction count dimension), not the share of created outputs. Moreover, this metric only captures NATIVE witness formats - it excludes P2SH-wrapped SegWit envelopes (backwards-compatible mode, counted in P2SH #366). The 'total' SegWit share including backwards compatibility would therefore be higher than this native aggregate.
