It looks like SDC went live with our solution for hashToEC.

They switched from creating a new generator, discussed here: https://bitcointalk.org/index.php?topic=1378922.msg14079014#msg14079014

What's this mean?

We are the leaders kids.

This is the heart of our algo, pushed publicly 9 days ago:

Code:

for (j = 0; j < k; ++j)
   {
   if (j == 0)
   x = u;
   else
   {
   secp256k1_fe_set_int(&i, j);
   secp256k1_fe_add(&x, &i);
   }
   if (secp256k1_ge_set_xquad_var(&Q, &x))
   {
   success = 1;
   break;
   }
   }

This is shadowcash's pushed to their repo 3 days ago:

Code:

while(!EC_POINT_set_compressed_coordinates_GFp(ecGrp, ptRet, bnTmp, 0, bnCtx) && count < 100)
   {
   count += 1;

   if (count == 100)
   return errorN(1, "%s: Failed to find a valid point for public key.", __func__);

   BN_add(bnTmp, bnTmp, bnOne);
   }

This is their commit after they read our critique of their method:

https://github.com/shadowproject/shadow/commit/106afc6975cf41090ca2a0c47877de0cc8a16f1a

SDC used fix that EC came up with first

Is this true?

Shen did a fantastic job helping out this open source project.

Did Shen fix the bug? Did he go on to do a full review?
