Speed

Tests with 10 cores:

• from block 30500962 to 32926204 (2.425.242 blocks) took about 15 minutes.

  • The out file had 11872 lines. ~620 transactions were not found on RPC provider.

• from block 27419649 to 30500962 (3.081.313 blocks) took about 3 minutes 41 seconds.

  • Most of the transactions were not found on RPC provider.
  • Rerunning this block range resulted in 5 times more transactions.

It could take about 2~3 hours to find all transactions assuming they're known to the RPC provider.

Issues

• ethClient.Client.FilterLogs do not return any logs for some old blocks. Example: 18687544

  • The block hash do not match with the hash read from ethclient.

• RPC provider returns not found for some transactions.
