Hello, I'm thinking about writing a BIP about resetting the testnet on
regular/scheduled basis

The idea works like this:
* Every 210000 block is being used as the genesis of a completely new chain.
* The old one gets forgotten
* No chain can be longer than 210000 blocks

The problems are:
* How to get this working with testnet3? Only a hardfork probably.
* Is it that easy to change the chain while Bitcoin Core is running?
Probably the blocks need to be appended to the cureent one. After a
restart it would get patched
* Could the the chain derive into multiple once at every reset? (Planned
attacks)

What do you think about the idea?

Greetings,
Emil Engler
