Privex is now running a public STEEM RPC Server to help the community

in dev •  last year

Last month, @jesta stopped maintaining STEEM.WS - the first public public RPC node.

For those who don't know what an RPC node is: - An RPC Node is a server which allows applications to interact with the STEEM blockchain. When you use Steemit.com, your browser connects to the RPC node ran by Steemit Inc. (wss://steemd.steemit.com), which gives it information such as posts, upvotes, whether your log in is valid etc.

Example: An RPC node is used by applications such as Steemit.com, AnonSteem, Busy.org, and other software built on the STEEM platform. They require a lot of resources to run (currently requires 104GB of RAM and rising every day).

While Steemit.com runs a public one now, it has shown to be unreliable at times, and so we needed more, to allow for less centralisation, as many projects depend on Steemit Inc's server.

We're now running our own public RPC node to help the community out.

We've added it to the STEEM.CENTER Public Websocket Server list

SPECIAL OFFER

Want to run your own RPC server? Need a server provider that accepts crypto (inc. STEEM and SBD)?

We're now selling this exact same 256GB RAM server on our website for a very low price (it'll probably be going up in the next few weeks, so grab it while it's cheap!): https://www.privex.io

In other words, less than 24 hours of a top 20 witness' pay. The top 20 witnesses should be more responsible and ensure there's no lack of RPC nodes for the Steem network.

·

I did notice 1 top 20 witness supporting the other top 20 witness get this up and running. Ironically I don't believe you're voting for them. You may not realize, but $350 of the money raised is from the Minnow Support Project. Also, @netuoso and @someguy123 who are two witnesses running these are both leaders in the Minnow Support Project. You should come visit us some time. We're doing good things for Steemit.

·

Vote me to top 20 and I will make sure I do that

·
·

You already have my vote... we need responsible witnesses

·
·

I'll raise you 5 RPC nodes if I'm top 20 😎

·
·
·
·

What are top 20 witness paid a day ?

·
·

Witnesses from 1-20 receive around 0.1 SP per block. With 1 block per minute that equals to roughly 144 SP per day. But please do mind that this is SP (Steem Power) and is locked in to the account and requires a power down process that pays 1/13th of the total amount per week.

·

you are correct

I've ran a quick benchmark (fetching 100 blocks) against online nodes, and steemd.privex.io's results are not in line with the rest.

It might be nginx or steemd configuration issue.

·

Any response to this? Was it a temporary thing, or still a problem?

we need this , thank you

Awesome! I've added your node as a default in my benchmarking tool over at https://bench.steem.vc

But it is behaving a bit differently than the other nodes, getting errors for the get_follow_count call.

Thanks for your contribution. Just curious - by registering it on steem.center, will steemit.com users automatically start utilizing it?

·

Normal users will never deal with this information. This is mainly for developing applications and pointing them to an API server. A user might have to select a new server if one goes down, but at the moment such functionality doesn't exist via SteemIt. (it does in eSteem. hopefully @good-karma will update eSteem with the new nodes available)

Privex, you rock..keeping steemit secure and stable 100%

Very good news Thanks for taking this initiative to further add resiliency to this growing community. Highly rEsteemed.

That's good. Really good. Keep up good work.
Upvoted

Great news and thank you for breaking it down for a novice like me to understand.

I wish I would be able to start using it myself
But I am waiting to have my house first by the end of the year
Keep it up

That is awesome information and thank you so much for breaking it down for somebody who doesn't really understand the complexities of crypto yet. 💕🌹

this is very important for this community, thx for the information and for sharing it!

that sounds awesome... we all wanna steemit grow and to be on top of the list...!!!

Why would we want to run a RPC server? does it earn STEEM?

·

It supports the entire network and makes using applications possible in the first place. Why would YOU want to run it? You would be the only person that can answer that question.

As for me ... I chose to run my own RPC node because there are very few of them and I am an active witness and STEEM based developer that is trying to get more known. I contribute a lot of time and effort, and provide my skills as a system administrator capable of running, updating, and scaling a server such as the ones required for this undertaking.

Having a server with 100+GB ram at the very minimum becomes quite costly when using cloud hosted providers. It is far more affordable with personally owned and managed equipment, but this comes at a cost of having fire monitoring systems, redundant internet connections, power failover, physical space, and network bandwidth in tip-top shape.

So what do you choose? How much do you have to spend? What is your technical background?

All of these are necessary questions one must ask themselves when hosting production level servers for thousands of users.

·

It could if you ask for donations or support to run it...

·
·

I just ask for witness votes

Wow dev

Wow thats some heavy duty hardware. Thanks for helping to keep steemit growing!

Im not to familiar with steemits interworkings, but would cloud distributed computing be worth looking into in this situation? I would be happy to dedicate a pc to something like this when I get stable internet next month. Im sure many other steemians feel the same.

·

Be warned that so called "cloud computing" costs a lot. A properly specced server on Google Cloud Platform or Microsoft Azure could set you back thousands per month, compared to physical hardware which is much cheaper.

·

My bad I think I used the wrong term. I was referring to programs such as BOINC, where you can donate some of your computers processing power towards certain projects

Thanks for information on steemit
upvoted and followed you if you like cuteaniamals please follow me

i am trying to catch you guys but it looks like you are so far

hello offer is still available?

this is awesome
