user64911: I just see this transaction which is special : one of input address is spending a valid amount… But why is it unparsed ? Why no ScriptSig while stil being valid ?
Also what’s the purpose ?

user7272: The output being spent is a native segwit output. If you look at the transaction that created it, you get 0014644a61cf83439e53b5dd413bec63c98c9e39c107 for the lock script, which is a native segwit p2wpkh output.
Spending a purely segwit output requires no value to be set for the scriptSig (unlike for a p2sh-p2wpkh).
The address is shown as unparsed as Insight has not been updated to recognize bech32 addresses.
