i have used this code for hashing unsigned tx above :

Quote

import hashlib
e = m.decode('hex')
z = hashlib.sha256(hashlib.sha256(e).digest()).digest()
z = z.encode('hex_codec')
print z

and resulting :

19cc06bd75255f3594abeca69af20b505c7f2737dea64e4d2e36ba69f06ed092

so the r, s, and z pair from signed tx is :

Quote

z = 0x19cc06bd75255f3594abeca69af20b505c7f2737dea64e4d2e36ba69f06ed092
r = 0x4117f9f3173b915d03be6170d7af520bfa78d9d9fd35c829d974d3aaead09ae9
s = 0x8a032016f639b730779945f7b5bedb3701a0645c1752c1b27fccc617019f172b

and still resulting that the signature is invalid Huh

this is the resul :

C.xy = 0x760a4453d69c21c2c17131867f3862a802036818cbc6abaec5091cafa30b9825
r = 0x4117f9f3173b915d03be6170d7af520bfa78d9d9fd35c829d974d3aaead09ae9

i confused about this......

i think... i have missed that hashing result must be reversed! are it?
