when a fork of depth 1 is observed the DIFF=2 is raised and rate of block generation is halved
deeper forks than 1 cannot be healed.

So, as a DOS attacker, I create 1000 forks at depth 1 and the DIFF skyrockets freezing the chain?

I will be doing the technical part in my spare time
I'm pretty confident this project will be successful and by that I mean
It will either be mineable as an demo (possibly later as an altcoin or even real Bitcoin).
I also set myself the ideal (don't promise) to either write a paper (I'm not an academic tho)
or at least provide a huge amount of live test data from a working system.

by working system I don't mean an altcoin (too ambitious) or even deployed
on real Bitcoin (one can dream right).

I want to have the minimal viable product e.g to have the block creation
operating at desired level (think 1 block per second) and the orphans
resolved, doublespends reverted.

Very difficult part will be the visualisation of the results.

Then once ready, we can maybe ask a core dev to comment on this I think that would be a nice
conclusion of the project.

been toying with ideas how to reduce orphan rate

this idea of exponential difficulty backoff comes to mind

in standing state the network quickly mines low difficulty blocks DIFF=1

when a fork of depth 1 is observed the DIFF=2 is raised and rate of block generation is halved
deeper forks than 1 cannot be healed.
the fork then can be merged by the successor block and potential doublespend conflicts are resolved
by a list of TX ID's to revert in successor block.

when fork is settled the block speed is slowly falls to maximum again
after two succesive blocks of DIFF=4, the difficulty is again halved to 2, then two more blocks to 1 etc.

obviously the fee doubles with difficulty also
larger blocks have 2x capacity and so on

malleability is fixed by seg witness or schnorr sig etc
