### What Split out point negation part ([0945897](0945897)) from #1449, and address review comments on this part. ### Why Improves usability of the BLS12-381 features in a Groth16 verifier application ([example contract](stellar/soroban-examples#350)) - `Neg` is an common operation, needed for using the proof parameter as pairing input, and is cheap and simple enough to be implemented as an sdk function. ### Known limitations [TODO or N/A]

### What Add support for BLS12-381 curve points (`Fp`, `Fp2`, `G1Affine`, `G2Affine`, `Fr`) for internal data storage (via `contracttype`) and contract invocation arguments (contract spec). ### Why Improves usability of the BLS12-381 features in a Groth16 verifier application ([example contract](stellar/soroban-examples#350)) - `Arbitrary` and several missing conversions are needed to use `G1Affine`, `G2Affine` as contract data. ### Known limitations [TODO or N/A] --------- Co-authored-by: Leigh McCulloch <351529+leighmcculloch@users.noreply.github.com>

What
Implements a Groth16 verifier contract, and in the test verifies a simple proof generated off-chain.
See README for how the proof and verification data was generated.
Here is the demo
Why
This implementation demonstrates the BLS12-381 curve operations in Soroban, enabling zero-knowledge proof verification on-chain. The simple multiplication circuit (
a * b = c) serves as a proof-of-concept for more complex ZK applications.Known limitations
