Weekly Dev Update #30

Overview

The team spent the week building out a complete THORChain implementation in python, called Heimdall. This will allow the team to test and validate all outputs of THORChain in order to ensure the state machine is operating as designed.

With recent news of FCoin Exchange becoming insolvent due to what appears was a backend accounting error that allowed users to withdraw more than what they should, testing and validating for 100% funds accounting is a top priority for the project.

The team are also still implementing a solution to improve THORChain TSS reliability.

Heimdall

As discussed, this implementation is primarily to mock a complete THORNode in python so that funds accounting can be validated. The week’s merges are below.

• Do 1 transaction and compare its correct
• Adds “add” handler
• add rest of the swap runs
• add unstake transactions
• refactor and cleaning up
• Add smoke tests to a live thorchain
• Add integration tests
• reorder withdraw transactions
• fix linting errors
• Add health checks
• Use logging instead of print
• [refactor] remove expected num of outs
• [refactor] Breakpoint cleanup

More bounties will be placed soon.

Audit

Code Review: 3/4 Review Complete

Economic Review: Commenced

TSS Audit: delayed pending TSS re-design

Next Milestones

The updated testnet is in the final stages of testing. The current blocker to release is the re-design of THORChain TSS to achieve the reliability metrics the team want. A solution is being implemented for this.
