Hi Antoine,

Regarding potential malleability pertaining to blocks with only 64 byte 
transactions, why is not a deserialization phase check for the coinbase 
input as a null point not sufficient mitigation (computational 
infeasibility) for any implementation that desires to perform permanent 
invalidity marking?

Best,
Eric
