The way blockchain is currently implemented, a distributed ledger for currency necessitates having a chain that grows bigger and bigger. But one could have a distributed ledger which doesn't keep a record since the beginning of time. The ledger could only be valid for, let's say a week, and everything before then is just lopped off. It would still be large, but it wouldn't be gigantic.

There might be ways to "remove" data like your parent comment mentioned, but they would probably require making the sharing process a lot more convoluted.
