Is it possible to get latest update time of contract variable without preserving the transaction hash,
contract Demo{
uint numb;
function setNumb(uint var1){
numb=var1
}
}
in above contract whenever the numb is updated using setNumb(uint), transaction is fired and was saved in some block, if I want to know the time stamp of block in which the transaction is stored I can get the block by using Transaction hash and easily get the block time stamp,
But what if I don't know the transaction hash
Is it possible to get the latest transaction time(ie. block time stamp) which updates numb, Is there any way to get the block/blocks which stores transactions related to numb
