Can we add a test where we go back 100 blocks to verify the authors are correct? I think we do something similar with tanssi and aura, see https://github.com/moondance-labs/tanssi/blob/master/test/suites/smoke-test-common-parachain/test-block-author-logs.ts

However I guess you will need to compute a vrf verification, so not sure how easy this is from typescript..

Description of the PR please!

I was not able to do this because I don't know how to create the message to be verified. It's not a simple concatenation of bytes but something more complex, and with no javascript impl, see https://docs.rs/crate/merlin/latest/source/src/transcript.rs#69
