Bitcoin’s price has been rising at a rapid rate in the recent months. With the increase in bitcoin’s price, more and more companies are looking at the opportunity of setting up bitcoin mining operations. Several media outlets have regarded bitcoin mining as a waste of energy and have expressed their fear about the future of electricity consumption by bitcoin mining. In this article, I will try to debunk these fears and try to explain why bitcoin’s electricity consumption shouldn’t be a problem in the future.
How Bitcoin Mining Works?
Bitcoin mining is a process of solving a cryptographic puzzle which requires computer processing. As more devices join the bitcoin mining operation, the puzzle becomes more difficult and requires more processing and as devices leave the bitcoin mining operation, the puzzle becomes easier and requires less processing. The miner who solves the puzzle is allowed to create a block which is then added to the bitcoin’s blockchain and broadcasted to everyone who is using bitcoin. These blocks include transactions that are then validated by bitcoin nodes.
In return to the power spent by miner, the miner is awarded 12.5 bitcoin plus the sum of fees of all the transactions that he included in his block. This process secures the bitcoin blockchain from attacks from large entities that can try to push invalid blocks to the bitcoin blockchain securing the bitcoin ledger.
Debunking The “Bitcoin’s Electricity Consumption” Problem
A recent article by Motherboard compared Bitcoin’s electricity usage to Visa’s Electricity usage. The post claimed that Visa’s datacenters can process 1000 times more transactions per second with the same amount of electricity that bitcoin uses.
The argument seems fair but the reality is different. Bitcoin’s power consumption has nothing to do with bitcoin’s throughput. Bitcoin can process same amount of transactions with 1000 times less electricity than it is using right now. More electricity does not mean more transactions processed per second. Bitcoin’s scale is limited by its technology rather than electricity. More miners means more security for the bitcoin network and not more transactions processed per second. The electricity consumed by the bitcoin miners goes towards securing the bitcoin’s blockchain’s immutability.
Also rather than comparing bitcoin to Visa or any other company, Bitcoin should be compared to the traditional money or internet since bitcoin is not a company rather it is a network. And we all know that securing bitcoin leaves far less footprints than producing and securing cash or securing the internet.
With the increase in adoption of bitcoin, we will start seeing IOT devices that will allow normal devices such as refrigerators, washing machines, heaters etc. to do all the bitcoin mining operations. This will allow bitcoin to drift away from traditional ASIC mining which currently only secures bitcoin to more efficient mining schemes which aside from securing bitcoin does traditional household jobs too. This is still a long way from where we are.
