As of 2021, the Bitcoin network consumes about 93 terawatt hours of electricity per year – around the same energy consumed by the 34th-largest country in the world. Every 210,000 blocks, or about once every four years, the number of bitcoin received from each block reward is halved to gradually reduce the number of bitcoin entering the space over time. As of 2021, miners receive 6.25 bitcoins each time they mine a new block. The next bitcoin halving is expected to occur in 2024 and will see bitcoin block rewards drop to 3.125 bitcoins per block.

Transactions consist of one or more inputs and one or more outputs. When a user sends bitcoins, the user designates each address and the amount of bitcoin being sent to that address in an output. To prevent double spending, each input must refer to a previous unspent output in the blockchain. The use of multiple inputs corresponds to the use of multiple coins in a cash transaction. Since transactions can have multiple outputs, users can send bitcoins to multiple recipients in one transaction.
