Spending Taproot UTXOs
Videos
- Introduction to Taproot - Nicolas Dorier - short video
- Very good, practical introduction to coding taproot Transactions - Bitdevs LA
Descriptors/Miniscript
We can use Descriptors/Miniscript to precisely and human readable describe the Transaction outputs of the escrow transaction pipeline. This improves readability and portability of the pipeline.

Signature/Pubkey aggregation
To combine multiple parties pubkeys to a single combined Taproot pubkey and to create a aggregated signature with all participants MuSig2 is relevant.
Videos
- MuSig2 in Taproot - Nicolas Dorier - higher level explanation
- MuSig2: Simple Two-Round Schnorr Multi-Signatures - very detailed, more crypto focused explanation
Sighash Types
Maybe sighash flags could be a useful tool? It's possible to construct a transaction with multiple inputs/outputs from different parties using signatures committing only to specific inputs or outputs.
