			I added PHP code this code will help beginners with what is going on. The code is simple and well documented anyone regardless of PHP knowledge should be able to read this and know how to hash Bitcoins. [[User:RomanKnight\|RomanKnight]] 10:23, 11 January 2014 (EST)

	Doesn't it take more effort to calculate the Merkle root for 10,000 transactions than it does than for 1 transaction? Of course, you only have to do this once per block, but it's misleading. It seems you're using "hashing a block" to specifically mean the (iterative) hash calculation, not the process of block generation. I recommend rewording to :		Doesn't it take more effort to calculate the Merkle root for 10,000 transactions than it does than for 1 transaction?
