Cryptocurrency mining has witnessed remarkable advancements over the years, with various algorithms driving the process. Among them, the Scrypt algorithm stands as a formidable force, powering the mining of popular digital assets such as Litecoin and Dogecoin.
Scrypt is a hashing algorithm used on certain Proof of Work blockchains. It was first introduced with the launch of Tenebrix (TBX) in 2011.
Since then, Scrypt has been adopted by a number of different blockchain projects. Among the top three Scrypt-blockchains by market capitalization, the Scrypt mining algorithm secures over $3 billion in digital currencies as of the time of this writing.
In this guest blog post, we will provide an in-depth overview of the Scrypt mining algorithm and explore how the Antminer L7 leverages its capabilities to deliver outstanding performance and profitability.

What is Scrypt?
Scrypt was among the first hashing algorithms to be used on blockchain networks. In particular, the SHA-256 algorithm, which was a previous hashing algorithm, is being attempted to be improved.
Password-based Key Derivation Function
Key derivation function (KDF) known as Scrypt uses passwords. A KDF is a hash function used in cryptography that uses a pseudorandom function to derive one or more secret keys from a secret value, such as a master key, password, or passphrase. KDFs are generally efficient at preventing brute force password guessing attacks.
However, before the creation of Scrypt, FPGAs and ASICs could only be overcome with a certain degree of success by KDFs like Password-Based Key Derivation Function 2 (PBKDF2). While not memory-intensive, PBKDF2 and other password-based KDFs required a lot of computation. Scrypt was created to be both memory and computationally intensive.
ASIC Resistance
ASIC mining rig dominance and the subsequent centralization of cryptocurrency mining were both addressed by the development of Scrypt. Scrypt is meant to outperform SHA-256, which is used in the Bitcoin network and other Proof of Work networks that support digital currencies, in terms of blockchain.
Because of Scrypt’s design, miners must quickly produce random numbers. These figures must be kept in the processor’s Random Access Memory (RAM), which needs to be continuously accessed prior to submitting a result. In comparison to SHA-256 networks, Scrypt networks typically have much lower hash rates. For instance, at the time of writing, the hash rate for Litecoin (LTC) is approximately 138 TH/s. The hash rate for bitcoin is approximately 93,000,000 TH/s.
How Effective Has Scrypt Been At ASIC Resistance?
Looking at Scrypt’s effectiveness at ASIC resistance requires an assessment of how Scrypt ASICs have emerged over the years and the current state of mining profitability with these units.
CPU Mining and GPU Mining
With the launch of the first commercially-available ASIC rigs in May 2014, CPUs quickly began to lose their ability to mine Scrypt coins. As stated earlier, Litecoin’s implementation of Scrypt wasn’t as memory intensive as it could have potentially been. It’s difficult to say how much longer it would have taken for ASICs to become available if harsher parameters had been chosen from the start.
Scrypt-ChaCha, Scrypt-N, and Scrypt² are all variations of Scrypt that add more memory-hardness to the original Scrypt implementation. However, these designs have yet to gain significant adoption. Blockchain projects that have launched since the emergence of Scrypt ASICs have mostly chosen other Proof of Work hashing algorithms such as the CryptoNight mining algorithm or the Equihash algorithm.
Current Mining Profitability With ASICs
Bitmain Antminer L3++ and Antminer L7 are two popular ASIC mining rigs available for both LTC and DOGE mining. There are certainly more ASIC options for mining SHA-256 coins. This is a result of the dominance of Bitcoin and the fact that SHA-256 was never intended to achieve ASIC resistance. Thus, Scrypt has comparatively few ASIC options.
Nonetheless, you’ll likely find it necessary to have an ASIC rig in order to have a chance of competing for block rewards and reaching mining profitability for LTC, DOGE, and other Scrypt-based cryptocurrencies.
Advantages of Scrypt Mining
Scrypt mining offers several advantages over other mining algorithms. The memory-intensive nature of Scrypt makes it more resistant to certain types of attacks, enhancing the security of the network. Additionally, the Scrypt algorithm allows for faster block generation times, facilitating quicker transactions and confirmations. These advantages make Scrypt mining a compelling choice for miners looking to explore the world of Litecoin, Dogecoin, and other Scrypt-based cryptocurrencies.
Litecoin and Dogecoin Mining: Capitalizing on the Scrypt Algorithm with the Antminer L7
Litecoin and Dogecoin have emerged as two prominent cryptocurrencies that utilize the Scrypt mining algorithm. Let’s delve deeper into the mining potential of these digital assets and how the Antminer L7 enables miners to capitalize on their profitability.
Litecoin Mining
Litecoin, often referred to as the silver to Bitcoin’s gold, was one of the earliest cryptocurrencies to adopt the Scrypt algorithm. Created by Charlie Lee, a former Google engineer, Litecoin offers faster block generation times and a larger supply cap compared to Bitcoin. This makes Litecoin an attractive option for miners seeking quicker transaction confirmations and a more accessible mining process.
With the Antminer L7, mining Litecoin becomes a highly efficient and rewarding endeavor. The miner’s optimized power consumption, coupled with its high hash rate output, allows miners to maximize their earning potential while keeping energy costs under control. Whether you are a solo miner or part of a mining pool, the Antminer L7’s capabilities ensure that you can mine Litecoin with unparalleled efficiency.
Dogecoin Mining
Dogecoin, initially created as a lighthearted joke cryptocurrency, has gained significant popularity and community support over the years. Based on the Scrypt algorithm, Dogecoin offers fast block times and a friendly, meme-driven community. Its approachable and inclusive nature has made Dogecoin a favorite among cryptocurrency enthusiasts and miners alike.
The Antminer L7 empowers miners to tap into the potential of Dogecoin mining with exceptional performance. By harnessing the Scrypt algorithm, the Antminer L7 achieves high hash rates, enabling miners to validate transactions and secure the Dogecoin network effectively. Whether you are mining Dogecoin as a hobby or pursuing it as a profitable venture, the Antminer L7 ensures that you can optimize your mining operations and maximize your returns.
Diversifying with Dual Mining
One of the key advantages of the Antminer L7 is its ability to mine both Litecoin and Dogecoin simultaneously. This dual mining capability allows miners to diversify their mining efforts, reducing risks and maximizing profitability. By leveraging the Antminer L7’s power and efficiency, miners can tap into the potential of both Litecoin and Dogecoin, taking advantage of the unique features and market dynamics of each cryptocurrency.
The Antminer L7’s dual mining feature is especially beneficial for miners looking to balance their portfolio and adapt to changing market conditions. Instead of focusing solely on one cryptocurrency, miners can allocate their hash power to mine both Litecoin and Dogecoin, ensuring a diversified approach that optimizes earnings.
