Getting the wrong txid for coinbase transactions I'm trying to hash transactions to get the txid. I get the hex values from blockchain.info. I get the correct hash for all transactions except for the coinbase when I hash it twice. Is there something different about how the coinbase transaction is supposed to be hashed?

The block I have tried is: https://blockchain.info/no/block/0000000000000000000870497004514bd3807cdc98b9f3a57038faf5df04144f.


The txid of the coinbase is supposed to be:  
44763fed906f1a0e8b82e7497ac83856baa4b1c5621affdce04108a212018c4e

But I get:  
6e129e567970540b2812ec58388d131c3b8fdbf4e4c992d140e255895df2992e
The txid is the hash of transaction without segwit data. The full coinbase transaction contains the segwit data which will result in the hash that you got. However that is not the txid.
