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]}'

Happy Testing!
