-A _block chain_ is a list of _blocks_ that record transactions of a crypto-currency like BitCoin. A block might contain information like the time it was created (mined) and who mined it. The most important part of the block is it's _hash_. This is a special number made from the information in the last block of the block list combined with the hash number of previous block in the list. The new block contains information for the current transaction and this new hash number. The new block is added to the list of previous blocks. This list is then transmitted to the crypto currency network. It's really hard (like impossible) to tamper or forge a hash which allows the block chain to be transmitted publically.
