After +1 hour reading things start to be surreal. IOTA team swapped their in-house hash algorithm "Curl" for their new in-house hash algorithm "Kerl" in https://github.com/iotaledger/iri/commit/539e413352a77b1db2042f46887e41d558f575e5 https://github.com/iotaledger/iri/commit/539e413352a77b1db20... , while at the same day blogging about it and claiming their new in-house hash algorithm is actually SHA-3: https://blog.iota.org/upgrades-updates-d12145e381eb https://blog.iota.org/upgrades-updates-d12145e381eb > "Therefore we have made the simple decision to temporarily switch Curl with Keccak (SHA-3) for cryptographic signing in IOTA."
