I just fixed the PoW, all algos are supported: Cuckaroo, Cuckarood, Cuckaroom, Cuckarooz and Cuckatoo. There is also automatic detection based on the block header.
You can install using
pip install mimblewimble==0.10.0
Check code sample here:
def test_pow_algo_auto():
assert pow_validate(cuckaroo_header) == (True, EPoWStatus.POW_OK)
assert pow_validate(cuckarood_header) == (True, EPoWStatus.POW_OK)
assert pow_validate(cuckaroom_header) == (True, EPoWStatus.POW_OK)
assert pow_validate(cuckarooz_header) == (True, EPoWStatus.POW_OK)
assert pow_validate(cuckatoo_header) == (True, EPoWStatus.POW_OK)
Keep in mind the donations listener is still on if you want to support my weekend grinnin’

Hi all, I just released 0.11.0 which includes output scanning from node.
You can install using

I also did a prototype of ツ BTC atomic swap (as well as I managed to understand it)
I made some prototype code (as well as I managed to understand it, likely something is missing)
def test_atomic_swap_grin_success():
ctx = secp256k1_context_create(SECP256K1_CONTEXT_VERIFY | SECP256K1_CONTEXT_SIGN)
seed = bytes.fromhex("7f64b1861b9139c0601f637957826da80bb3773adbc8c70265a0c3edb6fda33b")
msg = b"grin success tx kernel message"
ORDER = 0xfffffffffffffffffffffffffffffffebaaedce6af48a03bbfd25e8cd0364141
def rand_priv():
while True:
p = os.urandom(32)
if secp256k1_ec_seckey_verify(ctx, p):
return p
# Alice keys
kA = rand_priv() # kernel nonce

KA = secp256k1_ec_pubkey_create(ctx, kA)
RA = secp256k1_ec_pubkey_create(ctx, rA)
