Title: Blog post: Fast blockchain scanning Post by: crispweed on June 20, 2014, 01:11:05 PM I just added a blog post about faster blockchain scanning through bitcoind RPC calls, by replacing gettransaction queries per transaction with getblock <blockhash> false and DIY block and transaction decoding.
The blog post is here: http://upcoder.com/8/fast-blockchain-scanning/ Feedback welcome. Thomas Title: Re: Blog post: Fast blockchain scanning Post by: phelix on June 20, 2014, 04:34:18 PM Interesting, thanks!

However in your example you end up with a raw encoded transaction, in the "obvious" case you have a nicely decoded transaction in JSON format... if I needed high speeds + python I'd rather use something like pynode or let Armory do the parsing for me, if I were just trying out stuff, the few GB or RAM or SSD space for the index are much cheaper than me writing a raw transaction decoder. |
