From 08844fd6eff55e756c453c6d2e16de40e8f80e73 Mon Sep 17 00:00:00 2001 From: Greg-Griffith Date: Wed, 18 Nov 2020 12:17:04 -0800 Subject: BIP34 specifies it requires minimal encoding. Non minimal encodings are rejected by the bitcoin-core client because it only checks against a specific encoding --- bip-0034.mediawiki | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/bip-0034.mediawiki b/bip-0034.mediawiki index a993b7e..88073c5 100644 --- a/bip-0034.mediawiki +++ b/bip-0034.mediawiki @@ -22,7 +22,7 @@ Bitcoin blocks and transactions are versioned binary structures.
