Coupled with the release of segwit in 0.13.1, there are 3 default relay and mining policy rules that may become softfork proposals in the near future.
Generally, users must not assume that a script spendable in pre-segregated witness system would also be spendable as a P2WPKH or P2WSH script. Before large-scale deployment in the production network, developers should test the scripts on testnet with the default relay policy turned on, and with a small amount of money after BIP141 is activated on mainnet. The rules include: 1. Only compressed public keys are accepted in P2WPKH and P2WSH (See BIP143 for details) 2. The argument of OP_IF/NOTIF in P2WSH must be minimal (see https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2016-August/013014.html) 3. Signature(s) must be null vector(s) if an OP_CHECKSIG or OP_CHECKMULTISIG is failed (for both pre-segregated witness script and P2WSH. See BIP146) The BIP141 and 143 are updated with the aforementioned rules: https://github.com/bitcoin/bips/pull/459/files _______________________________________________ bitcoin-dev mailing list bitcoin-dev@lists.linuxfoundation.org https://lists.linuxfoundation.org/mailman/listinfo/bitcoin-dev
