Well deserved - it’s great to see established companies providing grants for development
Ruben has done a fantastic job of synthesizing and leading research into privacy enhancements, and space chains are a neat concept that will be exciting to have explored more deeply

Glad to hear he got funding and can explore his ideas further, even if they flop having more people exploring different side chain solutions is a must if we want to scale this platform
LN focuses on a certain use case, Liquid focuses on another
I don't see why more side chains won't specialise

Lej, well done!

I think the economic and incentive model still needs improvement.
Either I or Ruben (so odds are it's me), don't understand why miners wouldn't have privilege. The users would have to post a multiple, greater than 1, greater than the UTXO that anybody can claim, in order to net out a fee that's much smaller. Eg. User would have to post a fee of 1.01 btc, to claim a UTXO worth 1.00 btc, just to net out actually paying 0.01. Otherwise, the miner would just take the 1.00 btc. Maybe there is something I don't get. Will re-watch/read more.
And, I can't help but notice, spacechain finality will be tightly coupled with Bitcoin's block time. So that axis of innovation (faster finality) feels restricted.
