I am one of the notaries who pays to have his node maintained. My rationale behind this is, my service provider has much more experience in network adminstration and infosec than i do and has demonstrated that he can keep up with updates, notarizations and respond in an attack scenario, which he did during the coin creation attack early in komodo's history.
The Notary Node funds that have been produced by my node have been used for many different Komodo related things including:
-Coinpayments.net integration
-Having a Komodo Book written for us: https://www.amazon.co.uk/Komodo-Fuel-SuperNET-Concise-History/dp/1981831452
-Conference materials
-Advertising
-Giveaways
Additionally, due to my inability to get a sweepstakes website up and running ( legal issues not technical ), I am planning to use the remaining funds of the notary year to establish masternodes in various BarterDEX enabled coins, the proceeds of which will be sold at discount on BarterDEX to encourage use of our DEX to many communities.
I wanted to point this out, as there is there are misconceptions about some of us notaries that aren't tech gurus, that we just leech the funds for solely personal profit.
It's good that your using some of your notary profit to help komodo, but I think there are many guys with no tech skills who would like to take your place, I'm one of them!
1500 KMD @ 3.90 = 5850 USD at todays prices, and this is AFTER recent crash .... and another guy does the work. Even if you paid that guy 2K USD a month, you're making ~1000 USD a week - who reading wouldn't want this deal? No risk, no stake, no (compulsory) work.
Don't misunderstand me, I'm jealous as hell, and think guys like you have a target on your back in this election ... I want what you have bro

Fortunately I was in the top half of notaries this cycle, so my single node is safe for another year.
Erroneous to assume that I havent taken risk or have stake. I do have significant stake in KMD , and take the same risk with my votes as everyone else does. I follow the notarynode channel and participate in the discussions on scaling komodo, and was a testnet operator and do know how to keep my node updated ( Just not that proficient ). Having someone more experienced manage my node, doesn't mean that I can slack on knowing what is going on.

From my perspective, a few veteran network admins / cybersecurity experts can maintain all the notary nodes if necessary. Having a decent variety of node operators distributed across the world, with unique perspectives and skillsets is necessary, however its easier ensure that all the nodes are updated and maintained when you have to wrangle up a number of operators that is less than the maximum. A happy middle I think can be obtained, if it appears to be too centralized for peoples taste then they will vote for unique operators.
The issue with security that concerns me is from political bickerings rather than on the tech side. Currently this is not an issue with Komodo, but as we have seen in other coins ( Bitcoin/Ethereum) politics can make even simple solutions arduous tasks.
@BigNaturals Good Luck next election if you decide to run!
