Glossary

“Bitcoin” is a type of digital currency in which a record of transactions is maintained and new units of currency are generated by the computational solution of mathematical problems (known as “Bitcoin mining”), and which operates independently of a central bank.

“Hashrate” is a measure of the computational power per second used when mining Bitcoin. It is measured in units of hash/second, meaning how many calculations per second can be performed.

“PH/s” refers to Petahash per second and “EH/s” refers to Exahash per second.
