2) It appears that I am unable to effectively explore the block chain by using a Transaction ID with the blockchain explorer here (
http://bt.nice-media.ru/chain/Zeitcoin). I would like to identify the from address of a specific transaction by using the Transaction ID.
Unfortunately we do not have working blockchain explorer at the moment.
It is unoffical one which is out of sync with the network.
It shows that last block was generated on 4th of March.
