[atodorov]

Description of proposed changes:

Practical tips for PR review & merge:

• All GitHub Actions report PASS
• Newly added code/functions have unit tests
  • Coverage tools report all newly added lines as covered
  • The positive scenario is exercised
  • Negative scenarios are exercised, e.g. assert on all possible errors
  • Assert on events triggered if applicable
  • Assert on changes made to storage if applicable
• Modified behavior/functions - try to make sure above test items are covered
• Integration tests are added if applicable/needed

FTR the stock GitHub runner takes 50 mins to import the blocks:

The self-hosted runner is less powerful and OOMs after 64 mins, never completing the job:

Logs from testing against testnet - https://github.com/gluwa/creditcoin/actions/runs/3968377925/jobs/6802244194
Logs from testing against main - https://github.com/gluwa/creditcoin/actions/runs/3968875445/jobs/6804989343

All PASS.

Note: the snapshot data used for testing is only for mainnet, I just copied the file and renamed it to include -testnet- in the file name. We'll need to regenerate new snapshots for proper testing.
