Is it possible for smart contract to view past transactions done on it, in other words would it be possible for a smart contract to see who has sent it Ether since its inception?

it is possible only if you had registred them (in a map for example). the smart contract hasn't the ability to explore the blockchain to know has a log of the transaction senders.

That is what I suspected. I am trying to write contract that accepts ETH and after a set date will allocate tokens to those, but as wel all know the fallback function cant do much (not even a save to a gloabl map) with a send().– RFVApr 26, 2017 at 15:47

1@RFVenter The contract could have a buyTokens payable function that checks the block number or timestamp and then allocates tokens.– eth ♦Apr 27, 2017 at 6:18
