A Bitcoin is created every time a puzzle is solved by a program designed to solve the puzzle, called a miner. Bitcoin becomes increasingly difficult to mine as more people join, which lowers the chances of a puzzle being solved by one program, person, or group. Mining pools were created to share the computing power across many miners to increase the chances of solving a puzzle. Pools split the profits when a Bitcoin puzzle is solved, but this reduces the payout for everyone in the pool. What Is Bitcoin Mining? Bitcoin mining refers to the process of digitally adding transaction records to the blockchain, which is a publicly distributed ledger holding the history of every Bitcoin transaction. Mining is a record-keeping process executed through immense computing power. Each Bitcoin miner around the world contributes to a decentralized peer-to-peer network to ensure the payment network is trustworthy and secure. Basics of Bitcoin Mining There are three ways to acquire Bitcoin: ...

Bitcoin’s effect on the environment has been a hotbed of discussion, dating almost all of the way back to when the cryptocurrency first launched in 2009. And now, over ten years later, researchers are still having trouble agreeing on an answer. What is Bitcoin’s carbon footprint, anyway? Depending on which study you cite, Bitcoin’s carbon footprint ranges from as little as 22 annual megatons of CO2 to estimates of over 50 megatons each year. Although numerous factors contribute to Bitcoin’s carbon footprint, it’s the network’s mining activities that have the most substantial effect. Thankfully, there are some solutions Bitcoin’s carbon footprint is undoubtedly nothing to shrug at. And as the mining difficulty continues to increase, miners will need to expend more energy to remain profitable. If they don’t find solutions to operate more efficiently, Bitcoin’s carbon footprint will continue to grow. As the rest of the world is moving toward renewable energy sources, Bitcoin m...
