   Please describe the feature you’d like to see added.

   Can I get the block or transaction data via the rpc api when the bitcoin core is still in the ibd process that has not been finished? For example , can I get the downloaded block data via calling the getblock api while the client is still in the ibd process?

   Is your feature related to a problem, if so please describe it.

   Yes this should work, did you try it? Here’s example commands starting bitcoind in a fresh datadir with -txindex:

    0--> bitcoin-cli -datadir=/home/pinheadmz/bcd-test getblockcount
    1400

   thanks, you mean that I can get the downloaded block and tx data via rpc api even though the bitcoin core is still in the ibd process and has not downloaded the full ledger data in the mainnet , right?
