mpcd is the production threshold daemon. With this commit it embeds
the JSON-RPC dispatcher from luxfi/threshold/pkg/thresholdd on a new
--threshold-listen flag (default 127.0.0.1:7300, MPC_THRESHOLD_LISTEN
env var). The dispatcher exposes every supported scheme:
cggmp21 (secp256k1 ECDSA, CGGMP21 fork)
frost (secp256k1 Schnorr, RFC 9591)
bls (BLS12-381 Shamir/Lagrange)
sr25519 (Ristretto255, via mpc node's own session — separate path)
pulsar (M-LWE / FIPS 204 ML-DSA-65 threshold, via luxfi/corona/threshold)
corona (R-LWE / Corona, via luxfi/corona/threshold)
doerner (reserved; upstream protocol non-functional, returns explicit error)
Wire format matches teleport/mpc/src/signers/rpc.ts byte-for-byte:
POST / {"jsonrpc":"2.0","id":N,"method":"<scheme>.<op>","params":{...}}
Methods per scheme: keygen / sign / verify. Public-key handles are
returned by keygen and bound on sign/verify.
Decomplecting note: the dispatcher carries zero policy. Profile
gating, auth, audit, and rate-limiting live on mpcd's existing API
surface (and on the cluster ingress in front of it). The threshold
listener is loopback by default; production exposure happens via the
KMS-facing ZAP server or the gateway.
There is no separate thresholdd daemon to deploy. The luxfi/threshold
repo's cmd/thresholdd remains as a developer / CI binary that imports
the same package — one wire, one implementation, two startup paths.
Tests: TestEmbeddedDispatcher_BLSRoundTrip (full keygen → sign →
verify → forgery rejection) and TestEmbeddedDispatcher_UnknownScheme
(-32601 method-not-found contract) both pass. README updated with the
new protocol table; full surface documented in
luxfi/threshold/LLM.md "thresholdd — unified JSON-RPC dispatcher".
