AppBase Testing
For the past few weeks, I have been testing the AppBase release candidate v0.19.4rc1. After working through some initial setup hurdles, I am happy to report that I have v0.19.4rc1
successfully running on one of my backup witness nodes.
AppBase RPC Node Needed
As I was testing the release candidate, I found out that the new version of the cli_wallet
(19.4
) is not compatible with RPC nodes that are not running the new steemd
version. In addition to the cli_wallet
being untestable without a 19.4
RPC node, there are a lot of changes in the 19.4
APIs that developers are going to want to test.
Based on this, I decided to launch a RPC server running AppBase 19.4
. The URL of the node is: appbasetest.timcliff.com
Hardware Specs:
- CPU: Intel 2x Xeon E5 2.3GHz
- RAM: 256GB DDR4
- Bandwidth: 500 Mbps, unlimited
- Disk: 2x450GB SSD NVMe
- Data Center Location: France
Please be aware of a few things regarding the server:
- This is a production
steemd
node. Even though it is mainly intended for "testing" - anything you do here is being done on the "live" production blockchain. - The sever does do moderate rate-limiting to prevent excessive use from taking the node down.
- This is not a "high availability" node. If it goes down, I will do my best to get it up as quickly as possible - but it may take a a few days or even up to a week, depending on what needs to be done to revive it.
- I based the configuration of the node off the fullnode.opswhitelist.config.ini example in the steem GitHub repository. I assume that this has everything that is needed, since it was everything listed in the example config for a full node. The list of what is enabled is below. If there are any other plugins or whitelist operations you need me to add - let me know and I will do my best to get them turned on.
- I plan to keep the server up to date with the latest AppBase release candidate / release versions published by Steemit, so if a new version is published - I will need to take it down to upgrade.
- I have not decided if I plan to support this indefinitely. I plan to keep it up for at least the next 2-3 months as everyone is testing AppBase - since there is obviously a clear need for it right now. We'll see in a few months where to go from here.

Example use
I assume that most people already know how to connect to and use an RPC node, but here are a few examples to get you started in case you don't:
cli_wallet
cli_wallet -s wss://appbasetest.timcliff.com
CURL
curl https://appbasetest.timcliff.com --data '{"jsonrpc":"2.0","id":0,"method":"condenser_api.get_account_history","params":["timcliff", -1, 10]}'

It will probably need to be updated to use the new “condenser” API methods, as was described in the steemitblog post.

A lot can change in three months. By then there is a pretty good chance that there will be several other AppBase nodes up and running. We'll see what the need is when the time comes.

You already know too well as much as I know that this is the best. No other AppBase node will fit in and deliver exactly like this one. I agree that there are other creative people out there, but no other person can precisely think out and reproduce exactly the same thing as another. I trust that you will not let us down @timcliff atleast for the sake of our followership. Just sustain this please

I don't really have a lot of time to get into the details, and I don't think most people will really even understand what they mean. In a general sense, I have been running the AppBase version of code with different configurations and verifying that the nodes operate as expected.

Just saw this in my feed - and I'd love to be able to make an intelligent comment, but this is pretty much where my understanding of the steem platform ends - at the technical stuff!
Still, I know yr one of the 'good guys' from yr various interviews and you've got our best interests at heart, and you actually 'work' - so cheers from all of us that aren't comfortable with 'writing on a command line' !
I might have to learn how to code/ set up a witness server - somehow I think it might be more 'steempowering' than sticking to economic and philosophical analysis!

Excellent tim! I would really love to see python-steem just work. Have you considered using a testnet chain for the rpc? The user @almost-digital has an rpc node and is running a testnet. It has 16GB of RAM! That's the testnet for you.
Downvoting a post can decrease pending rewards and make it less visible. Common reasons:

Not at this time. I think there is more value in having a RPC that is connected to the actual network. Steemit is working on a testnet though. Once that is up and running, there will likely be a need for interfaces.

See my blog on the testnet here:

I want to give the users of my application a good experience. So, I wouldn't just plug this into a website under production. As you wrote, this node is for testing. So that's the use case of this RPC node.
Something like that lends itself better to use a testnet. I can create accounts at will on testnet, and send fake Steem dollars and fake Steem. I run a test webserver that is only for uses @almost-digital's blockchain and then I do a bunch of testing with that one before I upgrade the code on the production site.
Anyway, it is good thing to have this RPC node up now. So things do not break in production! Right now, python-steem is not appbase ready.

That’s pretty awesome! You seem to be pretty involved with development. What other projects are you working on? Are you in the SteemDevs discord group?

The only one I spend much time on is steemfiles.com. The site is for buying and selling digital goods (files). These could be e-books, music, videos, or software. The products are there but the demand is poor. Perhaps users who use Steemit are not the demographic that would normally pay for digital goods, as they grew-up always having bittorrent and getting all digital goods for free. Except for crypto-currencies of course.
So, I think I should try to allow prospective vendors still host their files for free but I want to link how much they vote for Steemfiles posts with how much they can upload. So, if someone up-votes Steemfiles a-lot, they get more capacity to host their e-books, or whatever.
I am unable to install Discord because of OS compatibility issues. The requirement is that I use an OS that uses 8-byte wide pointers at least in the Linux case, and I am a Linux user. Since the computer I have doesn't have 4GB of RAM it is a waste of memory to give every pointer 8-bytes. There is steemit.chat. I signed up to steemit.chat with my tablet, that's why I am 'lepechaun' instead of 'leprechaun' over there.

Guess, Steemit has free AppBase and is prepared to check it on giant scale. These changes area unit 'under the hood' to create steemit easier to code for, and additionally quicker.

Such a wonderful project. You have done a great work. This project is really great, I like it.
I didn't know anything about 'AppBase (19.4) RPC node' , after reading your post , I have learned a lot about STEEMER.NET Project & its uses, new tools, newly added features. It will help lots of people. Thanks man for doing such a wonderful job, keep on enrich Steemit with your great work

After this release one should be able to edit posts even after the payout(7 days). Right?

In this comment, @vandeberg confirmed that the next release will contain this feature.
Now, after enabling content editing with
enable_content_editing
json will I be able to edit my posts older than 7 days by broadcasting the transaction to your node(appbasetest.timcliff.com
)? Or do I have to wait till all the witnesses update their nodes to the new version?Downvoting a post can decrease pending rewards and make it less visible. Common reasons:

It will need to be running on witness nodes. You will not need all witnesses to update though. As long as the transaction is processed by a witness that accepts it - it will make it in.

Thank you for clarifying.
I see that the witnesses are still running on 0.19.2(at least top 100). Any idea on when are witnesses planning to update to the latest version?
Downvoting a post can decrease pending rewards and make it less visible. Common reasons:

19.4 is still a release candidate (not an official release). It is unlikely that any of the witnesses will run the non-release version in production, so at least until the official release is made.
