This method also prevents the bitcoin network from being hacked. However, because the difficulty of mining increases more and more computing power must be used. As a result of there being more energy consumption, there are more costs involved (including the costs of wear and tear on the hardware).// | + | //[[dido:public:ra:xapend:xapend.a_glossary:b:bitcoin|Bitcoin]], the most popular [[dido:public:ra:xapend:xapend.a_glossary:c:cryptocurrency|cryptocurrency]], uses the PoW consensus algorithm.
