Hello Nano community,
I chose to invest in Nano over Bitcoin because I believe Nano has many advantages over Bitcoin while being a valid & compliant consensus network.
Upon research, I have discovered that Nano's advantages are true, and that its consensus is sound; nevertheless, I believe there is a flaw: availability. Someone, after having done enough work, could, at any given time, deny the network of service via precomputing the work and saturating the network.
Availability is key for the well-being of any payment infrastructure. It is my understanding that Nano has no notion of time in its ledger. So my question is: why not fork a notion of time in order to secure the availability of the network?
