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 0.8.3 (git0115d58)

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

Get the bootstrap address

Please use this bootstrap address

"rnode://f4f20286feebc89d36d11b9e6ad726b6dd3d1490@35.243.229.81?protocol=40400&discovery=40404"

Follow instructions for validator bonding

Instructions for validator bonding are in the User guide for running RNode.

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

We observed nodes catching up to the state of an existing blockchain. Due to a misunderstanding of the contents of the bonds file at genesis, we were delayed in being able to test validator bonding. We were able to test in the last 10 minutes and saw two validators bond and demonstrate validation. One validator bonded and had his bond in a orphaned block. He was not able to validate after bonding (`InvalidUnslahshableBlock`).

We observed a node unable to peer with all nodes on the network and therefore be unable to quickly catch up to the state of the blockchain.

We did not observe the InvalidParents error, indicating the estimator fix worked.
