Some of the Pros of the Ethash Algorithm(https://www.cryptominerbros.com/blog...
1. It is the Ethash algorithm is easy to use, safe, and simple to use. Its ASIC resistance makes the whole mining process less centralized which allows everyone to participate in Ethash mining even without the use of sophisticated equipment such as ASICS.
2. It’s much faster as compared to other methods. Furthermore it’s DAG structures in memory cache, and Keccak function makes the algorithm more efficient in production of blocks. This means that Ethereum is able to adjust its production times based on the requirements of its network in real-time and ensures the perfect balance between scalability and security.

Ethash has a reputation for protecting the blockchain from potential attacks and enhancing its security. Here are some key characteristics of Ethash-

1. Memory-Hardness
   Ethash, a memory-hard algorithm, requires a large amount of memory in order to mine and validate ETC transactions. This helps maintain a blockchain that is decentralized.

2. Dagger-Hashimoto Structure
   Ethash is the combination of two algorithms - Dagger and Hashimoto. It is therefore unique, and it gives you the benefits of both algorithms. It is an efficient and highly secure hashing algorithm.

3. Directed Acyclic Graph
   Ethash creates a pseudo random dataset, the Directed Acylic Graph (DAG), that is frequently updated, such as every 30,000 blocks. This takes about five days. This prevents pre-computational attacks and ensures that mining is based on memory.

To learn the details about Ethash and the way it functions first, you have to know the initial version, known as Dagger-Hashimoto. The two primary features of Dagger-Hashimoto include (i) ASIC resistance and (ii) extremely reliable and easily verified.

Two of the above mentioned elements determine the Dagger-Hashimoto operation. Dagger-Hashimoto is a combination of two algorithms. The dagger algorithm was invented in the hands of Vitalik Buterin The Hashimoto algorithm was created through Thaddeus Dryja. It employs direct acrylic graphs (DAG) to create massive data structures. While the structure had more than 1GB of storage space, it now requires 4 to 5 GB.

The DAG structure permits a set of memory-based calculations to be performed that can add an extra amount of work. Additionally, the structure allows the Hashimoto algorithm to execute efficiently in mining. The Hashimoto algorithm also adds ASIC resistance during processing hash function mining. This is accomplished by causing it to use the capacity to consume a lot of RAM since this is the limitation of ASICs.
