Why are miners allowed to change a tx id?
Why are miners allowed to change a tx id? BIP 62 proposed to make transaction malleability impossible. Why was this retracted and why are miners allowed to change a transaction id? Also, what does it mean when someone says signatures cannot sign themselves? Is this implying we not only need a signature for the transaction, we need another signature for the transaction + signature? http://ift.tt/2oVtPHC
