Hi @Congyuwang ,

I have encountered an issue where the get_transaction function fails after around block 622,000 - possibly due to the Bitcoin Core version 0.19.1.

Would you happen to know of any workarounds for this issue? Thank for your help!

I updated the bitcoin_explorer package to the latest version, 1.2.20.
I am trying to read block 787036, 787037, 787038 to the latest block.
But it stuck at block 787037, take hours and hours, but still don't get anything.
What's the problem please?

Hi,

I am using bitcoin core 25 to download the blockchain data.
I get this error message when running

db = bq.BitcoinDB("/home/neri/.bitcoin/", tx_index=True)
[20:13:36] INFO - Start loading block_index
thread '' panicked at 'block hash not found in block index!', /root/.cargo/registry/src/index.crates.io-6f17d22bba15001f/bitcoin-explorer-1.2.20/src/parser/block_index.rs:125:18

pyo3_runtime.PanicException: block hash not found in block index!

Any idea how to solve the problem?
Thanks, Filippo

I'm using the explorer in a regtest mode bitcoin-core and when I use the function "db.get_transaction()" for a specific transaction, it returns the following data:

[23:35:22] INFO - Start loading block_index
[23:35:23] INFO - Successfully opened tx_index DB!

If I check the same transaction with bitcoin-cli gettransaction I get the following data:

}

Why the data don't match? for example, doesn't appear in the return of the bitcoin explorer, or if I check the transaction that appears in the input of the bitcoin explorer ('39a1aca5790d939d75159e43fc02c77a621c3c6119bc18fd32efee66e17b5657') bitcoin-cli returns that is invalid.

Thanks for reading.

I get following error during initialization (Python 3.8.11).

I have data downloaded using Bitcoin Core in D:\BTC\Chain\blocks (.dat files) and D:\BTC\Chain\blocks\index (.ldb files).
