Contract Events are a useful feature for storing data from smart contracts exclusively for off-chain use.
Unfortunately current ethereum implementations provide a very inefficient lookup mechanism.
By using linked events that always link to the previous block with a change for the identity,
we can solve this problem with much improved performance.
Each identity has its previously changed block stored in the changed mapping.

Lookup previousChange block for identity
Lookup all events for given identity address using web3, but only for the previousChange block
Do something with event
Find previousChange from the event and repeat
