Implemented getConsolidationChurnLimit and getActivationExitChurnLimit (
Consensys#8203) also added to the electra upgrade, and wrote a test to show the computations, but these will be tested further when we can run reference tests too. We should be able to pass state upgrade from deneb now, but we'd need to confirm via reference test. fixes Consensys#8147 Signed-off-by: Paul Harris <[email protected]>
