This is some fast code to iterate over bitcoind's block files to

extract blockchain data from the main blockchain.

## To build:

1. make

## Things you can do:

Show block hash and transaction size for each transaction in the main chain:

	./bitcoin-iterate -q --tx=%bh,%tl

This will produce output like:

    000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f,204

    00000000839a8e6886ab5951d76f411475428afc90947ee320161bbf18eb6048,134

    000000006a625f06636b8bb6ac7b960a8d03705d1ace08b1a19da3fdcc99ddbd,134

    0000000082b5015589a3fdf2d4baff403e6f0be035a5d9742c1cae6295464449,134

    000000004ebadb55ee9096c9a2f8880e09da59c0d68b1c228da88e48844a1485,134

…

Show output script sizes in the main chain (block number, transaction

number, output number, output script length):

	./bitcoin-iterate -q --output=%bN,%tN,%oN:%ol

This will produce output like:

	0,0,0:67

	1,0,0:67

	2,0,0:67

	3,0,0:67

	4,0,0:67

…

Show the five largest blocks, by height and blockhash:

	./bitcoin-iterate -q --block='%bl %bN %bh' | sort -nr | head -n5

This will produce output like:

	999993 343188 96395be50a116886fb04a1262aa89aaa765c4af524d0ae090000000000000000

## Enhancements

Happy to consider them!

You can reach me on IRC (rusty on #bitcoin-wizards on Freenode), and

of course, via pull requests and the [Github bug

tracker](https://github.com/rustyrussell/bitcoin-iterate/issues).

Good luck!
