When we say the words “block” and “chain” in the context of blockchain, we are actually talking about digital information (the “block”) that is stored in a public database (the “chain”). The Bitcoin protocol is built on the blockchain. So, with the launch of Bitcoin in 2009 as the first cryptocurrency, blockchain technology had its first real-world application.

Originally, Bitcoin’s creator intended for bitcoin to be mined on central processing units (CPUs)—your laptop or desktop computer. However, Bitcoin ASICs surpassed both CPUs and graphics processing units (GPUs) in terms of both their reduced electricity consumption and greater computing capacity. After gaining traction in mid-2013, when other hardware mining devices started hitting their bottlenecks in mining, Bitcoin ASIC miners have retained their lead.

What Is an ASIC Bitcoin Miner?

Although investing in cryptocurrency is painstaking, costly, and only sporadically rewarding, some investors are drawn to it. People buy expensive ASICS and pay for lots of electricity so that they may earn more bitcoin, which may be exchanged for real-world currency.

There are no physical “coins” in bitcoin, only balances kept on a public ledger in the cloud, that—along with all bitcoin transactions—is verified by a massive amount of computing power. Bitcoin is backed by millions of ASICs around the world called “miners.” By mining bitcoin, you can earn cryptocurrency without having to put down money for it. It is also the only way to release new bitcoin into circulation.

The first miner to find the solution to the puzzle is able to authorize the transaction (to add bitcoin to the block). Each winner in the Bitcoin-mining lottery receives a reward (a certain amount of bitcoin). The reward includes all of the transaction fees for the transactions in that block, which motivates miners to collect as many transactions into a block as possible to increase their reward.
