Applying ASIC in Cryptocurrency mining brings many outstanding advantages. So what is ASIC?
In this article, we’ll explore what ASICs are, their importance in the field of cryptocurrency mining, and some of their advantages and disadvantages!
What is ASIC ?
ASIC, which stands for Application-Specific Integrated Circuit, is an integrated circuit (IC) chip customized for a particular use, rather than intended for general-purpose use.
Today, ASIC technology is used virtually everywhere, in a wide range of fields, such as mobile phone microprocessors, microprocessors in automated machinery, media devices, vehicles, spacecraft, processing systems, industrial production lines, and more.
The importance of ASIC in mining PoW Coin and Bitcoin (BTC)
The essence of Proof of Work (PoW) is to confirm the validity of someone’s “mathematical solution” to the entire blockchain network. One of the first PoW coins was Bitcoin (BTC).
To better understand the nature and mechanism of Proof of Work, you can refer to: What is Proof of Work?
To mine Bitcoin, computers need to perform complex calculations called hashes, each with a chance of generating Bitcoin. The more hashes performed within a given timeframe, the higher the probability of a miner earning Bitcoin.
Initially, users mined Bitcoin using the central processing units (CPUs) of their laptops or desktop computers. Over time, with the growth of the crypto market, the profitability of mining increased, attracting more participants and making Bitcoin mining exponentially more difficult.
The emergence of ASIC mining tools is a direct result of this evolution.
ASIC mining tools refer to computerized devices or hardware that use ASICs for the sole purpose of “mining” cryptocurrency. Generally, each ASIC miner is built to mine a specific type of digital currency.
Simply put, an ASIC Bitcoin miner can only mine Bitcoin; they are optimized to solve its mining algorithm.
Advantages and Disadvantages of Using ASICs
Like any technology, using ASICs for cryptocurrency mining has its own set of advantages and disadvantages.
Advantages of ASICs
- More Efficient Cryptocurrency Mining: ASIC miners are specifically designed for the sole purpose of mining cryptocurrencies. As a result, these machines offer very high mining efficiency, allowing miners to extract more coins in the same amount of time.
- Enhanced Network Security: The competition for mining speed keeps ASIC manufacturers in a constant race to create more efficient machines. This results in increased network security due to the growing hashing power, making network attacks extremely expensive and unprofitable.
Disadvantages of ASICs
- High Energy Consumption: Firstly, operating ASIC miners consumes a significant amount of electricity. The cost of replacing and maintaining these miners is also quite high. Sometimes, these costs can even exceed the value of the mined coins.
- Limited Use Cases: While ASICs can be highly effective, their limitation to a specific use case renders them completely useless for anything else. Moreover, continuous technological advancements in the cryptocurrency space bring about new ASIC models that quickly make older designs unprofitable.
- Reduced Network Decentralization: The development of ASIC miners has inadvertently led to the emergence of mining pools. This mining model causes a concentration of hashing power, posing a threat to Bitcoin’s decentralization.
- Theoretically, the top four mining pools could collude to take control of the Bitcoin (BTC) network, which is currently considered the most secure blockchain in the world.]
What are ASIC-resistant coins?
ryptocurrencies that utilize ASIC-resistant algorithms are known as ASIC-resistant coins. The ecosystems of these tokens are designed to NOT be profitable when mined using ASICs. In fact, using ASICs to mine these tokens can even result in losses.
Instead, these tokens can be mined using standard graphics processing units (GPUs) and central processing units (CPUs). Some examples of ASIC-resistant coins include Ethereum, Monero, Ravencoin, and Vertcoin.
Benefits of ASIC-Resistant Algorithms
Using ASIC-resistant algorithms offers several benefits:
- Lower barrier to entry for miners: Miners can start mining with a relatively low investment (around a few hundred USD) without needing expensive ASIC miners (which can cost between 6,000 and 11,600 USD).
- Increased decentralization: By allowing anyone with a computer to participate in mining, ASIC-resistant coins promote a more decentralized and secure blockchain network.
- Protection against mining bans: Useful in cases where local laws suddenly prohibit mining, as China did in 2021.
- Reduced risk of 51% attacks: ASIC resistance makes it more difficult for a single entity to gain control of a majority of the network’s hashing power, which is necessary to launch a 51% attack.
Why ASIC Resistance Matters
ASIC-resistant coins are designed to promote fairness and accessibility in cryptocurrency mining. By making it possible for individuals with regular computers to participate, these coins help ensure that mining remains decentralized and less susceptible to the control of large mining farms. This contributes to a more secure and democratic blockchain ecosystem.
Note when wanting to become an ASIC Miner
Since ASIC miners can be quite expensive, you should consider several factors before spending tens of thousands of dollars on an ASIC mining rig:
- Which cryptocurrency do you want to mine? The list of cryptocurrencies that can be mined with ASICs is much smaller than those that can be mined with GPUs. Popular mineable cryptocurrencies include Bitcoin, Litecoin, Ethereum (before its transition to Proof of Stake), and some other PoW coins.
- Where will you install the miners? ASIC miners generate a lot of heat when operating. This means that setting up a mining rig in your living space is not a good idea, as it can cause discomfort. Ideal locations include a basement, garage, or a dedicated rented space.
- Electrical system: The latest generation of ASIC miners consumes a significant amount of power. If you decide to become a home ASIC miner, you should consider upgrading your electrical wiring to avoid potential hazards.
- Joining a mining pool: Mining pools allow miners to combine the power of their ASIC miners to increase the chances of mining Bitcoin and share the rewards among participants. Instead of becoming a home miner, another option you can consider is joining a mining pool.
