London, England, 4th Nov 2021, Bitcoin mining is the process of securing and verifying bitcoin transactions—payments from one user to another on a decentralized network. Mining involves adding bitcoin transaction data to Bitcoin’s global public ledger of past transactions. Each group of transactions is called a block. Blocks are secured by Bitcoin miners and built on top of each other forming a chain. This ledger of past transactions is called the blockchain. The blockchain serves to confirm transactions to the rest of the network as having taken place. Bitcoin nodes use the blockchain to distinguish legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere.
Bitcoin mining is so-called because it resembles the mining of other commodities: it requires exertion and it slowly makes new currency available at a rate that resembles the rate at which commodities like gold are mined from the ground.
FinancialCentre Broker Dave Goldman says that bitcoin mining is intentionally designed to be resource-intensive and difficult so that the number of blocks found each day by miners remains steady. Individual blocks must contain proof of work to be considered valid. This proof of work is verified by other Bitcoin nodes each time they receive a block. Bitcoin uses the hashcash proof-of-work function.
The primary purpose of mining is to allow Bitcoin nodes to reach a secure, tamper-resistant consensus. Mining is also the mechanism used to introduce bitcoins into the system: Miners are paid any transaction fees as well as a “subsidy” of newly created coins. This both serves the purpose of disseminating new coins in a decentralized manner as well as motivating people to provide security for the system.
The environmental aspect of mining
The environmental aspect of mining is an important problem. Already, miners have been forced to use hydroelectric power in countries where the majority of mining farms are located as a result of government restrictions on coal electricity. Hydroelectric power is favoured as it has a minimal environmental impact as well as is abundant and cheap. environmentalists have been arguing for a while that bitcoin mining is wasteful, especially for a currency that aims to be environmentally friendly. For example, one study has shown that bitcoin mining consumes more than 30 TWh per year and could soon exceed the entire energy consumption of Ireland. At that rate, bitcoin mining would not be sustainable for another 100 years.
Many countries have either banned, restricted or delayed the use of bitcoin mining. China has declared that bitcoin mining is illegal while Venezuela has made it difficult for miners to operate. Some other countries like Russia and Kyrgyzstan have proposed outright bans on cryptocurrency altogether while India recently imposed harsh restrictions on all crypto-related banking activity.
Green mining is a process by which Bitcoin mining can be made environmentally friendly. The idea of green mining is an implementation of renewable energy sources in order to reduce the environmental impact, and therefore increase the efficiency of the miners themselves. Currently, most Bitcoin farms are built near hydroelectric power plants or ordinary coal-fired power plants due to relatively cheap electricity costs. However, this makes these facilities vulnerable during droughts or if water temperatures rise too high, making them less efficient. Some mining facilities have already been forced to shut down due to increasing water temperatures leading to a lack of cooling and subsequent overuse of energy.
One idea is to import cheap electricity produced by renewable sources such as solar and wind power plants in desert regions far away from the main population centres where most Bitcoin farms are located.
A step ahead
MintGreen is a Canadian based mining company that has recently entered a contract with Lonsdale Energy Corporation where they will work to supply the heat from bitcoin mining to North Vancouver by the time we enter next year. The representative has said that the company has some boilers that are efficient enough to make use of the 96%of the energy that is being used by miners to mine the digital coins. As a result of this contract, 20,000 metric tons of greenhouse gas per megawatt will be prevented from entering the atmosphere.
Mr Goldman says that as for now, this is expected to be a great step forward in the right direction. It will reduce the amount of energy that is being used as waste as well as will also help to bring down the cost as well as carbon dioxide emissions. This will also help to boost the Canadian economy as well as provide jobs for people who are living in the area. He also said that MintGreen is a company that is committed to the environment and wishes to make a difference. He also said that it seems like the race for renewable energy sources has begun. MintGreen is one of many companies that has either started or will be starting operations in order to benefit from the cheap electricity costs of using solar and wind power plants.
