 # Proof of Work
 
+Bitcoin Cash uses a [hashcash](https://en.wikipedia.org/wiki/Hashcash)-like algorithm as a primary metric for validating new blocks.
+The [block header](/protocol/blockchain/block/block-header) is hashed, its nonce is changed, and it is hashed again, until the resulting hash begins with an expected number of zero-bits.
+This repeated hashing with an updated nonce is referred to as mining.
+For more information on how the number of zero-bits required is determined, see [Difficulty Adjustment Algorithm](/protocol/blockchain/proof-of-work/difficulty-adjustment-algorithm).
+For more information on how mining is performed in practice, see [Mining](/protocol/blockchain/proof-of-work/mining).
+
+Because SHA-256 is used to hash block headers, and it is not known how to find a input matching a certain output format, the proof-of-work system employed by Bitcoin Cash distributes the following quasi-randomly to the individual that successfully creates a block that meets the proof-of-work requirements:
+
+ 1. The responsibility of determining which transactions will appear in the block.
+ 2. The receipt of the block reward for the block.
+ 3. The receipt of the fees for the block.
+
+This is only quasi-random because the likelihood of building a block with an appropriate hash is directly proportional to the computational power (often referred to as hashing power), available to each individual mining blocks.
