You can also add my latest build:

Thom has some very good points. I will add a couple of things from my point of view:

Bare minimum:
The truth is that all you need is a home computer with 8GB RAM and some 8GB swap file and you can run a witness. You don't have to do anything else except for being voted in as active <-- very cheap and very crappy at the same time

What a witness should have (VPS/server running costs):
- a server can cost anywhere from around $1K to $3K
- Co-location costs around $80 to $200/month if you want something decent
- Dedicated Server $80 - $150
- VPS  about $60 & up/month if you want decent RAM

In my opinion an active witness should have at least 3 (I have 3 and will be adding more - one in May)

It costs BTS to do price feeds,  and here again the number of assets that witnesses post prices for vary because there is no set list that we should go off.

The more servers we have (I think Thom has 6) the more time it takes to maintain them. Some witnesses provide additional work for the community  and maintain other products.

I think it's important to build a capable network of Witness Node servers and the motivation should not be the witness pay. We just need more active witnesses capable of providing the backbone infrastructure for DEX. For example, in addition to the voted in witnesses I would like to see a Network select witness that's selected during the maintenance window based on his/her Server capabilities (connection, RAM etc.) - if there is a way to measure that properly. Because few proxy voters have not changed their votes for months some active witnesses feel very secure and provide very little feedback on their activities.

As far as the hours and monthly pay, lately I have been putting in a lot more than 5 hours but I am ok with your $400 as pay was not my motivation (and I suspect there are few others that share that opinion). If we can focus on improving DEX and adding traders, it will help us to generate higher income for DEX. At the same time based on the BTS reserves we should have a plan to decrease witness and worker pay to generate an overall profit and maybe create a dividend for all share holders. With the rising price of BTS we might be able to get there quicker.

I just updated to 0.4.10, but the asset does not have the "Witness fed asset" tag and since I am not on the list my RUBLE price feed is not being published.

It wasn't clear that you wish to publish price feeds, but we have 2 more places
I'll add you to the list

Few posts ago @alt asked you to change the flag on the asset so all active witnesses can do the price feed. I think it will be a better solution than trying to lock it in to a specific group of people. I think it would be a better long term solution.

@JonnyBitcoin
Thanks! I appreciate your confidence and the tip. You can have my votes as well if you ever need them.

@rnglab
The websocket exposure was only during the initial synch (per the docs guide) but I will skip it on my next build. Thank you.

So the 8GB was an initial recommendation I found browsing through the forum. My build uses 16GB and it's pushing its limit. I am looking at 32GB for my final build (aiming at a 2 year life cycle)

@alt
I meant this threat to be a guide for people to help secure the network, I am not even soliciting anything. I will write my witness proposal later when I get done tuning it and get the final build.
But I guess there is always a hater so to answer you quickly:
- about 'bue' - I like swiss cheese
- Running a witness is a RESPONSIBILITY and I would think that it is in community's interest to build a pool of capable witnesses, both active and standby
- If you keep hating on every new comer, you will not be able to grow this community
- and as far as the active witnesses go, they are mostly voted in by two people only
Feel free to look me up on https://bitcointalk.org or https://talk.peercoin.net/


@tbone
Thanks

sorry I just saw this today.
and you have my support
I am not hate for newcomer, I just need be carefully, because I have saw so many scam happened in Bitshares

Great, thank you. Let's take it to the next level together, it will be good for everyone!

• Coding experience: PHP, javascript, python, mysql. Helped out @fav with a referral code script and @iHashFury with code reviewing the Altcap.XDR script. I've made available on my Github a Steem Witness Monitoring script and a Golos Pricefeed script

Great proposal!

Your price feed script has only:

• Livecoin
• Liqui
• Bittrex
• Kuna
  

and I see you are working on Poloniex. Do you plan to add other feeds to cover MPAs?
[/list]

Hi @sahkan thank you for notifiying. As I mentioned that was a sample of code I supplied to other graphene communities. In this case Golos. Being a Golos witness means supplying a dedicated Golos feed to the Golos blockchain. The Golos coin was only listed on those 4 exchanges. (Now only on 3 for the moment). Hence that specific pricescript only has those exchanges incorporated.

Re: your question:
I currently plan to use @xeroc 's pricefeed script which I have tested but can not publish the feeds which are only for active witnesses. If you check Bitshares overview you will notice that I currently publish ALTCAP.XDR. This is a script I codereviewed from @iHashFury and intend to have that 'manual' script for more MPA's yes.

I don't want to saturate your proposal here, but I am trying to get a grip on this price feeding so we can get some governance and guidance that all witnesses are willing to follow. A list of required price feeds should be one of them. Please provide some feedback at https://bitsharestalk.org/index.php/topic,24006.0.html Thanks!

 

You already got my vote. The workload is increasing on the witnesses and we need a future-ready infrastructure.
