01f0bacf79 Started modifying scriptSig to be compatible with atomicdex-style HTLCs. This removes support for P2PKH inputs, but Pirate doesn't support these anyway. 2022-05-18 22:51:45 +01:00

a2e12ea51e Attempt to redeem P2SH with secret. This is highly experimental. 
Based on Qortal standard HTLCs. Will need adapting to Pirate specific ones at the very least.

15e229509a ff: Move pow_vartime back into Field trait 
The only places we don't use constant u64 limbs, we use PrimeField::char
instead (except in a single test where we use a field element).

fb31d09218 ff: Remove Ord bound from PrimeField 
ff_derive still implements Ord and PartialOrd for the fields it
implements, because pairing::bls12_381 internally assumes that those are
implemented. Once we delete that implementation, we will remove the Ord
and PartialOrd implementations from ff_derive.

38f87c2e73 ff: Add PrimeField::ReprEndianness associated type 
This enables generic code to reliably operate on the bits of an encoded
field element, by converting them to and from a known (little)
endianness.

The BitAnd and Shr bounds on PrimeField are now removed, as users can
perform these operations themselves as needed.

55568b4d6e ff: Remove frobenius_map from Field trait 
It is only used internally in the bls12_381 crate, and field extensions
aren't exposed anywhere in the Zcash stack.

1761ebfb35 ff: Remove SqrtField trait 
The sqrt() function is now part of the Field trait. ff_derive returns an
error on fields for which it does not support generating a square root
function.

Note that Fq6 and Fq12 in pairing::bls12_381 leave the function
unimplemented. They will be dropped once the migration to the bls12_381
crate is complete. The equivalent structs in that crate are not exposed.

49f119fb03 ff: Remove PrimeFieldRepr trait

bounds, which can be satisfied by a newtype around a byte array.

b6457a905b ff: Move pow_vartime into a trait that is generic over the limb size 
The trait is implemented by default for u8 and u64, allowing pow_vartime
to be used with both the byte encoding and limb representation of field
elements.

is all we need now that a CommitmentTreeWitness can compute its root.

2064d1c801 Refactor zcash_primitives::merkle_tree::CommitmentTreeWitness 
- The internal Option wrapper was an unnecessary leftover from when this
  code was directly inside the prover, where Some(x) represents an
  assigned variable.
- CommitmentTreeWitness::from_slice_with_depth is more idiomatic Rust.

Constant-time field inversion 
WARNING: THIS IS NOT ACTUALLY CONSTANT TIME YET!

The jubjub and bls12_381 crates will replace our constant-time usages,
but we NEED to fix ff_derive because other users will expect it to
implement the Field trait correctly.
