Semantically it is very similar to the existing `multi()` descriptor, but with the following changes: * The corresponding script is `<key1> OP_CHECKSIG <key2> OP_CHECKSIGADD <key3> OP_CHECKSIGADD ... <key_n> OP_CHECKSIGADD <k> OP_NUMEQUAL`, rather than the traditional `OP_CHECKMULTISIG`-based script, making it usable inside the `tr()` descriptor. * The keys can optionally be specified in x-only notation. * Both the number of keys and the threshold can be as high as 999; this is the limit due to the consensus stacksize=1000 limit I expect that this functionality will later be replaced with a miniscript-based implementation, but I don't think it's necessary to wait for that. Limitations: * The wallet code will for not estimate witness size incorrectly for script path spends, which may result in a (dramatic) fee underpayment with large multi_a scripts. * The multi_a script construction is (slightly) suboptimal for n-of-n (where a `<key1> OP_CHECKSIGVERIFY ... <key_n-1> OP_CHECKSIGVERIFY <key_n> OP_CHECKSIG` would be better). Such a construction is not included here.

2022-02-07docs: Move explanation of hardened key syntax closer to KEY sectionBitcoin Hodler
Before 7cedafc5412857404e9a6c3450b100cb8ee4081a added the TREE section, this line appeared right after the KEY section. It doesn't really fit in its former location since it's the KEY section that discusses derivation path syntax, not the TREE section.

I try to follow the steps laanwj outlined there exactly, with the exception of using `combinepsbt` instead of `joinpsbts`. I wrote a functional test to make sure it works as expected before doing the docs, and figured it would also be a good source of documentation. So I kept the test as simple as possible and didn't go crazy with edge-cases and various checks. I do have a lot more test-cases I've written that I will follow up with (either in a separate PR or another commit - lmk if you have a preference), but I want to do it in a way that doesn't bloat this test so it remains useful as a quickstart (unless that's a bad idea)? ACKs for top commit: S3RK: Code review ACK 9de0d94. Rspigler's argument convinced me that we should leave the workflow with two wallets. I assume using multisig with external signers is a popular use-case and it's important to keep compatibility. laanwj: Code and documentation review ACK 9de0d94508828f5fdfaf688ccda5a91d38b32c58 Tree-SHA512: 6c76e787c21f09d8be5eaa11f3ca3eaa4868497824050562bdfb2095c73b90f5e8987a8775119891d6bfde586e3f31ad1b13e4b67b0802e1d23ef050227a1211

2021-09-03test, doc: basic M-of-N multisig minor cleanup and clarificationsMichael Dietz
wallet_multisig_descriptor_psbt.py is refactored in this commit. While behavior doesn't change we do cleanup the way wallets are accessed throughout the test as this is done a lot for the various signers and their multisigs. We also get rid of some shallow methods and instead inline them for improved readability. descriptors.md is improved to be more explicit about which wallet (ie the signer or multisig) is required for each step.

2021-05-24Add tr() descriptor (derivation only, no signing)Pieter Wuille
This adds a new descriptor with syntax e.g. tr(KEY,{S1,{{S2,S3},S4}) where KEY is a key expression for the internal key and S_i are script expression for the leaves. They have to be organized in nested {A,B} groups, with exactly two elements. tr() only exists at the top level, and inside the script expressions only pk() scripts are allowed for now.

2020-11-06docs/descriptors.md: Remove hardened marker in the path after xpubDmitry Petukhov
As described in "Key origin identification" section, a descriptor that has hardened derivation after xpub does not let you compute scripts without access to the corresponding private keys. Such a descriptor is practically useless. The text after the descriptor said "with child key *1'/2* of the specified xpub", and clearly an xpub cannot have "child key" with hardened derivation. Therefore it makes sense to fix this inconsistency to not confuse the reader of the doc
