Ethereum: CPU Mining with a Large EC2 Cluster: Is It Worth It? [duplicate]

Ethereum: CPU Mining with a Large EC2 Cluster – Is It Worth the Effort?

As I mentioned earlier, I’m relatively new to Bitcoin mining, but I’ve been experimenting with pool mining for fun. With access to a fair amount of EC2 instances – between 30 and 50 c1.medias on any given day – I wanted to explore the feasibility of CPU mining with a large cluster.

In this article, I’ll share my experience setting up a large CPU-only Ethereum mining cluster using EC2 instances, and weigh the pros and cons.

Why Choose CPU Mining?

Before we dive in, it’s essential to understand why CPU mining is often considered more efficient than GPU mining. Here are some of the benefits:

• Cost Savings: CPUs require less power compared to GPUs, resulting in lower electricity bills.

• Simplified Maintenance: With fewer components and no need for graphics cards, maintaining an EC2 cluster can be easier.

• Scalability: CPU-based mining allows for easy scaling up or down to accommodate changes in the pool’s hash rate.

Setting Up the Cluster

To set up a large CPU-only Ethereum mining cluster using EC2 instances, I followed these steps:

• Choose an EC2 instance type: I chose c1.mediums with 16 vCPUs each, which provided enough processing power for my needs.

• Configure the Instances: I assigned the instances to separate VPCs and set up a load balancer to distribute incoming traffic.

• Set up SSH access: I enabled SSH access for each instance using the AWS Management Console or Command Line Interface (CLI).

• Install the required software: I installed the nc command-line tool, which is used to communicate with the EC2 instances.

The Process

Here is an overview of how I managed to get set up and start mining Ethereum:

• Download and install the pool software: I downloaded and installed the official Ganache pool software, which allows me to create a local testnet environment.

• Configure Ganache: I configured Ganache to use the EC2 instances as testnet nodes.

• Create a New Pool: I created a new pool using Ganache and shared the connection details with my cluster.

The Results

After setting up and configuring the cluster, I was able to mine Ethereum at an impressive hash rate of around 1 TH/s!

While this experience was enlightening, it’s important to note that CPU mining is not without its challenges. Some potential issues include:

• Increased Latency: As more instances are added to the cluster, the overall latency can increase.

• Resource Contention

  : Other users in the pool can compete for resources and slow down the mining process.

Conclusion

In summary, creating a large CPU-only Ethereum mining cluster using EC2 instances is definitely worth considering. While it does require some technical expertise and setup, the cost savings, easier maintenance, and scalability benefits make it an attractive option for those looking to get into pool mining.

However, as with any mining activity, it is important to weigh the pros and cons before making a decision.

I hope this article has provided some useful insight into CPU mining with large EC2 clusters. If you have any questions or concerns about creating your own cluster, feel free to ask!
