Cardano Stake Pool N+

Cardano Stake Pool Weakest Link

In every chain of reasoning, the evidence of the last conclusion can be no greater than that of the weakest link of the chain, whatever may be the strength of the rest.
~ Intellectual Powers of Man, 1786 by Thomas Reid D.D. F.R.S.E. (Page 476)

In the above image, I can spot three screws that are securing the seat a triangle shaped bar leads up to the chains themselves if anyone of these linked fasteners fails, the man in the swing will come crashing down.

Just like the swing above, operating a Cardano stake pool, a failure at any point will affect your uptime and possibly your pool rewards, bringing you down. A good Cardano stake pool operator will plan for failure, so no single point can take down their pool, be it humanmade or natural, the more failures your pool can sustain the more robust your pool will be.

Cardano Stake Pool N+1

A Cardano stake pool operating as N+1 represents the amount required for operation plus a single backup. The lowest redundancy level, N+1, is the minimum a public pool operator should be running at for nonstop performance. The diagram below illustrates an N+1 stake pool network.

Cardano Stake Pool N+1

Having N+1 redundancy comes down to two of everything, like having a spare tire for your car, you can get a flat and still be driving once you swap it out with the spare. But unlike a car, a pool operator should not have to manually failover their pool.

Operating a Cardano stake pool that has 100% uptime might seem impossible at first, it is not. The demands to run a nonstop stake pool is thinking in terms of failure points; the more failures you can sustain the more robust your pool will be. Redundancy can go well beyond N+1 many consider an N+2 as a minimum, other network administrators only sleep well when N+X is backing them up.

What about you, what is your N+ tolerance to get a good nights sleep, you don't want to be the weakest Cardano stake pool link now, do you?
