when NXT block chain does get "shrunk" will it remove previous version of an alias or retrain all the previous URI's in the alias?
For example: Jan 1 alias "helloworld" = "test1" and then Jan 10th updated "helloworld" = "test2" ... will the test1 record be completely removed from the block chain?
Also same question about AM. Will previous AM's get removed once the blockchain is shrunk?
My understanding (guess) is that there will be some data files that stores the current state of account balances and latest URI's, but not AM content.
There will (could) be service providers that store the entire blockchain from genesis block. Probably need to make sure that there are enough copies of entire block chain before any pruning.
