If you hold or move real size, your signing model is not a side quest. It is the thing. The control plane. The gate between intent and loss.
Two models dominate serious crypto ops: classic multisig and threshold signatures. They look similar from the outside. They are not the same inside. The right choice depends on how you weigh cryptography risks, human process, on-chain costs, and the blast radius if something breaks.
I will keep this practical. What each model actually secures, how it fails in the wild, and where the fees and paper trail land. Then a decision matrix you can actually use.

Security model
Multisig enforces quorum on-chain via script or contract. Threshold signatures (TSS/MPC) enforce quorum off-chain, producing one signature that chains accept as a single key.
Fees and footprint
With Taproot/Schnorr, FROST or MuSig2 can compress inputs to ~57.5 vB vs ~296 vB for 2-of-3 P2SH and ~350 vB for 3-of-5 P2WSH, cutting fees roughly ~80% in higher-th
