There is an error on the file /data/node/out/Release/node. How can I find this directory?
Hi:
After compiling witness generation code, the VERIFYING WITNESS step is failed on centos(works on my mac but it's tooooo slow)

Hi,
I'm trying to build the optimalate and verify (using yarn build:optimalate
in the main folder) and I'm get a problem (the example above is for optimalate):
****COMPILING CIRCUIT****
invalid output path
previous errors were found
DONE (0s)
****COMPILING C++ WITNESS GENERATION CODE****
build_optimalate.sh: 30: cd: can't cd to ../../build/optimalate/optimalate_cpp

}
I saw that there's no witness file, so I tried compiling the circuit separately. But then another problem appears when trying to run circom directly (using circom optimalate.circom --O1 --r1cs --sym --c
at circom-pairing/scripts/optimalate):

Do you know what causes this issue? (I'm using circom 2.0.4. Downgrading it to 2.0.3 did nothing)
When I try to run yarn test
, I get two errors, seemingly randomly one then the other:

Hi,
Nice project! I have the feeling the components at https://github.com/yi-sun/circom-pairing/blob/master/circuits/bls_signature.circom does not check if the signature and public key are 0 but I might be wrong:
// Inputs:
// - pubkey as element of E(Fq)
// - hash represents two field elements in Fp2, in practice hash = hash_to_field(msg,2).
// - signature, as element of E2(Fq2)
// Assume signature is not point at infinity
template CoreVerifyPubkeyG1(n, k){
If that is the case, for every message m, the BLS verification of e(g1, signature) = e(pubkey, H(m)) is always true.
I tried to use EllipticCurveAdd for aggregating public keys but found that it fails when aIsInfinity == 1
and the point a is at infinity.
I tried to log a few things and I suspect the problem comes from this line
circom-pairing/circuits/curve.circom
Line 340 in 743d761
As discussed on a call with @yi-sun.
I am passing in a 10 64-bit register value with overflown negative registers, which is equal to PrimeReduce
is not producing a 0 value.
The input (in javascript) is:

Why did you decide to not implement a circuit for hash_to_field.
And do you think such a circuit could easily be implemented?
When running build_finalexp.sh
in scripts/finalexp
, i got an error

Everything went okay, circom safe
