How would this prevent a flood attack ? What I mean is in Bitcoin and presumably Stellar, you need coins to create transactions. There is therefore a cost to spamming the system.

It doesn't prevent a flood attack. The challenge in this approach does not lie in "preventing it" but in "dealing with it".

Do you have some ideas on how to deal with it?

[buhrmi]

Yeah

Stellar is 100% centralized. In fact, its owners took it down at some point to change some rules.
