Thanks for the info. I guess this means that a bech32 format for private keys is not going to happen soon. Even if such a format was available, the issue would remain for segwit-in-p2sh addresses, which use base58. The ambiguity of the WIF format is currently holding me from releasing a segwit-capable version of Electrum. I believe it is not acceptable to use the current WIF format with segwit scripts; that would just create technological debt, forcing wallets to try all possible scripts. There is a good reason why WIF adds a 0x01 byte for compressed pubkeys; it makes it unambiguous. I see only two options: 1. Disable private keys export in Electrum Segwit wallets, until a common WIF extension has been agreed on. 2. Define my own WIF extension for Electrum, and go ahead with it. Defining my own format does make sense for the xpub/xprv format, because Electrum users need to share master public keys across Electrum wallets. It makes much less sense for WIF, though, because WIF is mostly used to import/sweep keys from other wallets. I would love to know what other wallet developers are going to do, especially Core. Are you going to export private keys used in segwit scripts in the current WIF format? _______________________________________________ bitcoin-dev mailing list bitcoin-dev@lists.linuxfoundation.org https://lists.linuxfoundation.org/mailman/listinfo/bitcoin-dev
