Really interesting! Digging into the proposal [1]:
> make it harder for attackers to overload the service with introduction
request
> We hope that this proposal can help us defend against the script-kiddie
attacker and small botnets.
Sets expectations: does not counter large botnets.
> We hope that this proposal will allow the motivated user to always connect
A user who really wants to connect can get through durring a DoS attack, but it may still take work.
Interesting choice of PoW algorithm: https://github.com/tevador/equix
> Hence, instead of forcing clients to go below a static target like in Bitcoin to be successful, we ask clients to "bid" using their PoW effort. Effectively, a client gets higher priority the higher effort they put into their proof-of-work. This is similar to how proof-of-stake works but instead of staking coins, you stake work.
