What you can expect this week
We will demonstrate using the blockstore to restore a node and support it catching up. We will test block finalization.
Instructions for testing today
Read documentation for RChain Doctor
Please read the RChain Doctor documentation and install RChain Doctor (v0.3.3). We will use this software and tools to support collecting logs from nodes participating in today's testing session.
Read the documentation for visualizing the blockchain
One of the challenges of debugging is seeing what's happening when validators propose new blocks. We now have the ability to ask RNode to generate a text file that when pasted to Graphviz can generate an image. Please see 'visualizing the blockchain' in User guide for running RNode.
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 0.8.4.git550be610 (550be610fb6ed70212782572284e71b49d209c8d)

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
Report your public key
Today we will launch a network with testers as known validators at genesis. Please report your public key in this form.
Get the bootstrap address
We will share the bootstrap address during the session.
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.
Work completed since the last testing session
Testing session summary
We had a very good testing session today. We demonstrated the functionality of the blockstore to support the restart of RNode in an active network environment. We also demonstrated how recent improvements to threading support faster connections to peers and receipt of blocks. Testers helped reproduce a known bug and support the debugging effort with the dev team. During the session we also discussed potential optimizations.
