How to convert bytes to an address
Those 22 bytes are:
2 bytes - encoded prefix (tz1, tz2, tz3, KT1);

Block confirmation
In 005-Babylon, fitness became a monotonically increasing number, simply representing the height of the block. Fitness is no longer calculated based on the number of endorsements within the block.
