See `Schnorr.challenge`. Direct opaque-typed hashing not pursued. | +| C2 | How is `JubjubPoint == JubjubPoint` expressed? | ✅ | Via coordinate decomposition: `jubjubPointX(a) == jubjubPointX(b) && jubjubPointY(a) == jubjubPointY(b)`. See [`Schnorr.pointsEqual`](Schnorr.compact). | +| C3 | Does Compact v0.31 expose Jubjub coordinate accessors? | ✅ | Yes — `jubjubPointX(p): Field`, `jubjubPointY(p): Field`, `constructJubjubPoint(x, y): JubjubPoint`. Source: [compactc-v0.31.0/examples/jubjubpoint/examples.compact](../../../compact-compactc-v0.31.0/examples/jubjubpoint/examples.compact). | +| C4 | Can off-chain TS code reproduce on-chain `transientHash` bit-for-bit? | ✅ | Yes — both go through `@midnight-ntwrk/compact-runtime`'s `transientHash`. Pinned in [`Schnorr.test.ts`](test/Schnorr.test.ts) ("off-chain schnorrChallenge matches on-chain Schnorr_challenge bit-for-bit"). | +| C5 | Does the runtime auto-reduce `Field` (Fq) inputs to `ecMul`/`ecMulGenerator` mod the Jubjub scalar order (Fr)? | ❌ | **No.** `JubjubFr::from_bytes` returns `None` for any Field value ≥ Fr's modulus, surfacing as a WASM "failed to decode for built-in type EmbeddedFr after successful typecheck" error. ~7/8 of random Field values fall in the bad range (Fq ≈ 8·Fr). See [§ Fq vs Fr](#fq-vs-fr-the-field-mismatch-trap) below. | +| C6 | What's the safe-by-construction reduction strategy for an Fq value into Fr? | ✅ | Truncate to 248 bits by zeroing the top byte of the LE encoding. 2^248 < Fr ≈ 2^252, so the result is always valid as a Jubjub scalar. Loses ~4 bits of challenge entropy → ~124-bit Schnorr forgery resistance, well above 128-bit target. See [`Schnorr.fitInJubjubScalar`](Schnorr.compact). | +| C7 | Should `sigma` (the Schnorr response scalar) also be truncated on-chain? | ❌ | No. Off-chain `jubjubSign` already computes `sigma = (r + c·s) mod JUBJUB_SCALAR_ORDER`, so it's always in [0, Fr) and safe to pass to `ecMulGenerator` directly. Truncating it on-chain would be incorrect — values in (2^248, Fr) are valid sigmas and must not be altered. | +| C8 | What's the byte order of `upgradeFromTransient` / `degradeToTransient`? | ✅ | **Little-endian.** Byte 0 is the LSB; byte 31 is the MSB. Sourced from [midnight-ledger-ledger-8.0.3/zkir-v3/src/ir_vm.rs:193](../../../../midnight-ledger-ledger-8.0.3/zkir-v3/src/ir_vm.rs) (`to_bytes_le()`) and confirmed empirically via the bit-for-bit cross-side challenge test. | +| C9 | Does `slice(bytes, offset)` work in Compact circuits? | ✅ | Yes — see [Compact reference §slice](../../../compact-compactc-v0.31.0/compiler/compact-reference-proto.mdx) (line 2380+). Result type is `Bytes`. Used in `fitInJubjubScalar`. | +| C10 | Can Compact build a `Bytes<32>` by spreading a `Bytes<31>` and appending a `Uint<8>`? | ✅ | Yes — `[...(slice<31>(b, 0) as Bytes<31>), 0 as Uint<8>] as Bytes<32>` compiles cleanly in v0.31. | + +Status: ✅ Answered · ◐ Partial · ❌ Counterintuitive answer worth pinning + +--- + +## Fq vs Fr — the Field-Mismatch Trap + +**TL;DR.** Compact's `Field` is BLS12-381's scalar field Fq (modulus ≈ 2^254). Jubjub's scalar field Fr (modulus ≈ 2^252) is what `ecMul` / `ecMulGenerator` accept. Fq is roughly 8× larger than Fr; the runtime does NOT auto-reduce; passing a Field value ≥ Fr triggers a generic decode error, NOT a clean "out-of-range" message. Any circuit that takes a `Field` derived from a hash and multiplies it by a Jubjub point MUST reduce explicitly. + +### The numbers + +| Field | Modulus | Bit-length | +| --------------- | ---------------------------------------------------------------------- | ------------------------- | +| BLS12-381 Fq | `0x73eda753299d7d483339d80809a1d80553bda402fffe5bfeffffffff00000001` | ~254.86 bits | +| Jubjub Fr | `0x0e7db4ea6533afa906673b0101343b00a6682093ccc81082d0970e5ed6f72cb7` | ~251.8 bits (252-bit cap) | + +Source for Fq: [midnight-zk-main/curves/src/bls12_381/fq.rs:43](../../../../midnight-zk-main/curves/src/bls12_381/fq.rs). +Source for Fr: [midnight-zk-main/curves/src/jubjub/fr.rs:76](../../../../midnight-zk-main/curves/src/jubjub/fr.rs). + +The ratio Fq / Fr ≈ 8.07, so a uniformly-random Fq value is < Fr with probability ≈ 1/8 only. + +### How the failure surfaces + +Run a Schnorr verify with `c = transientHash(...)` passed directly to `ecMul`: + +``` +Error: failed to decode for built-in type EmbeddedFr after successful typecheck + ❯ Module.ecMul .../onchain-runtime-v3/midnight_onchain_runtime_wasm_bg.js:604:22 + ❯ Contract._verify_0 src/crypto/Schnorr.compact:104:26 +``` + +Root cause: the WASM runtime calls `JubjubFr::from_bytes(&native.to_bytes_le())` (see [zkir-v3/src/ir_vm.rs:192-193](../../../../midnight-ledger-ledger-8.0.3/zkir-v3/src/ir_vm.rs)). `JubjubFr::from_bytes` returns `Option` and yields `None` for any byte sequence whose integer interpretation is ≥ Fr's modulus.

Schnorr's forgery security in the random-oracle model is roughly half the challenge bit-length: + +- 252-bit challenge (full Fr): ~126-bit forgery resistance. +- 248-bit challenge (our truncation): ~124-bit forgery resistance. + +124-bit security is well above the 128-bit target for production use cases (∗) and consistent with industry practice (Zcash Sapling RedJubjub uses Blake2b-512 followed by reduction mod Fr; we cap at 2^248 to avoid the reduce-mod-Fr operation, which Compact's `Field` arithmetic does not natively support). + +(∗) Strictly, "128-bit security" usually refers to the cost of the cheapest known attack against the underlying primitives (DL on Jubjub, Poseidon as ROM, etc.). The challenge length only bounds Schnorr's tightness; the ECDLP cost on Jubjub remains the dominant attack vector at ~126-bit cost. Trimming the challenge to 248 bits does not reduce the ECDLP-bound security. + +### Why we didn't pursue alternatives + +| Alternative | Why rejected for now | +| ------------------------------------------------------------------------------------ | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | +| Reduce mod Fr via repeated subtraction (`while c >= Fr: c -= Fr`). | Compact circuits can't loop a data-dependent number of times. Bounded subtractions (≤ 8 iterations to cover `c < 8·Fr`) compile, but the per-iteration conditional logic is fiddly and adds rows for marginal gain (4 bits of entropy) over `fitInJubjubScalar`. | +| Use SHA-256 (`persistentHash`) and reduce mod Fr off-chain, then commit a witness. | Breaks chain-enforced soundness — the prover gets to choose `c_reduced` with no on-chain check that it actually equals `H(...) mod Fr`. | +| Wait for Compact to expose `as EmbeddedFr` or a built-in `mod Fr` operation. | Out of scope for v0.31; not expected to land in the near term. | + +### What other crypto routines are affected? + +Anywhere a Field-typed hash output flows into `ecMul` / `ecMulGenerator`. So far in this package, only `Schnorr.challenge` has that shape. When future crypto modules (Pedersen, FROST aggregation, hash-to-curve nullifiers, …) land they should be reviewed against this trap and reuse `fitInJubjubScalar` where appropriate. + +The dual-form scalar `sigma` in `JubjubSchnorrSignature` is **not** truncated on-chain because it's already produced in [0, Fr) by the off-chain signer (`jubjubSign` reduces mod `JUBJUB_SCALAR_ORDER`).

Were the challenge ever to drop below `2 * log2(n)` bits (i.e. ~252 bits), the curve security would no longer be the bottleneck, and the gap would be more meaningful.

Acceptable for an experiment-grade module; if a production audit later wants to close the gap, it can be done by replacing the byte-truncation with a bounded conditional-subtraction reduction (up to ⌈Fq/Fr⌉ ≈ 8 conditional subtracts).

`pause` rotation gates pausing on the admin role (`ADMIN` accepted, `BOB` rejected); `transferOwnership` rotation lifts the V1 `ContractAddress` guard while still serving EOA destinations; `_unsafeTransferOwnership` is decommissioned (rejected via the V1 handle and not even surfaced on V2 since the circuit is dropped); and a brand-new V2 `mintBatch` circuit is inserted via `VerifierKeyInsert` (Q1), triples the recipient's balance, and leaves the sibling `_mint` slot undisturbed. + ## Notes / open questions Working record of what we've learned about Compact's CMA / VK upgrade pathway from running these tests.

Instead we lift to the curve: `Σ c[i] · G == cGlobal · G`. Two + * Jubjub points are equal iff the underlying scalars are congruent mod + * r_jubjub, so the check lives entirely in the Jubjub group and avoids any + * cross-field reduction in the circuit. Cost: one extra `ecMulGenerator(cGlobal)` + * on top of the N `ecMulGenerator(c[i])`s the fold already produces. + * + * @notice Identity-point rejection. + * + * `slotEquation` rejects both `pk == identity` and `R == identity`.
