What you can expect this week

We would like your help using a new log aggregation tool for nodes running on the network. We will use time in this session to help you get started using RChain DoctorRDoctor. Then we will join a test network and walk through a few scenarios. 

Work completed since Nov. 20

Instructions for testing today

Read documentation for RChain Doctor

Please read the RChain Doctor RDoctor documentation. We will use this software and tools to support collecting logs from nodes participating in today's testing session. Note, there are no new updates to RChain Doctor since last week. If you used it last week, please use it again. If you'd like to try again, please do . If it's not for your, no worries.

The session key for today is

Install RNode

Note If you used a previous version of RNode, please delete your existing .rnode directory. Most errors experienced using RNode relate to content in the directory from a previous version.

RNode version for this session

Today's version RChain Node 0.7.1 (081f969aea21bdd3d39c7680a8eccf8496ea8f9a)

• Binary packages (.deb, .rpm, and .tgz) https://repo.pyr8.io/rchain/downloads/testing/

• Docker image 

  Code Block
  docker pull rchain/rnode:testing

  
  

Select a validator key or generate one 

To select a key set

• Go to https://docs.google.com/spreadsheets/d/18merD3OzaDk7nmxQ78SUZBzWLbxA-aOnmcdxpXrp_U0/edit#gid=0

• Pick out a an unclaimed row with a validator key pair

• Specify your node if you want. You can wipe your information after testing

• If you use this key, you will join the network as a validator.

To generate a key set

• RNode supports ed25519 keys
• Generate an ed25519 key set:
  • Follow instructions from the Genesis protocol guide
  • If you're using Docker and have Python installed, the rchain-keys-generator

Bond to become a validator

• See instructions for bonding in User guide for running RNode
• Deploy bonding contracts to either
  • 52.119.8.203
  • 52.119.8.207

Share your experience

You best support the improvement and development of the RChain platform when you file a bug to report challenge you faced or unsuccessful outcomes. This will help us collect all relevant information to better understand your setup and experience. 

Testing session summary

RNode Doctor

We did have success collecting logs from some participants. We know the aggregation works. We also observed difficulties running the tool on the user side. We will work to improve the configuration and operation of the tool for next week's testing.

Blockchain

• Success in starting a test net 
• Success in adding peers to the network
• Limited success in nodes catching up to the state of the blockchain 
  • Some nodes had the full state 
  • Some nodes added up to 34 blocks and were unable to add more despite seeing new blocks added and requesting missing blocks from peers
  • Some notes added fewer blocks and were stuck
• No success bonding new validators because they were unable to add the block containing their bond
• Bootstrap node crashed with out of memory error. Nodes joining the network were able to join and not receive an approved block. Ticket created to add messaging that bootstrap is down.
• A validating node received a JustificationRegression error and was not longer able to propose
