The notion that anyone could solo mine bitcoin – on a CPU no less – seems positively quaint today. But in 2010, this method wasn’t just possible – it was the norm. With an exponentially lower hashrate, less competition and a 50 bitcoin block reward, there was enough pie for everyone to get a bite. But some miners didn’t just want a bite – they wanted a whole slice, and to achieve that, they decided to join forces and pool their hashpower. And thus “cooperative mining” was born.
