Ethereum: What is the approximate hash rate of a human?

The Ethereum network relies on a complex cryptographic system to secure transactions and control the creation of new units. At the heart of this system is the concept of hashing, which is used to create unique digital fingerprints for each transaction, block, and smart contract. But how fast can humans calculate these hashes?

Hash Rates and Mathematical Operations

To understand what we’re talking about, let’s delve into some mathematical terms.

  • Hash Rate: This refers to the number of hashing operations a computer can perform per second.
  • Mathematical Operations Required to Hash a Block Header

    Ethereum: What is the approximate hashrate of a human?

    : In Ethereum, each block header contains a set of mathematical instructions that the network executes. These instructions include:

+ Verifying the transactions in the block

+ Calculating the block timestamp and hash

+ Creating a unique digital signature (using a secret key)

+ Adding new blocks to the blockchain

  • Estimated hashrate: The estimated time it takes a human to perform these mathematical operations is about 1000 to 2000 times slower than on a modern computer.

How ​​fast can humans calculate hashes?

To put this into perspective:

  • A professional cryptographer can spend days or weeks on a single block, and the estimated time is about 10–20 hours.
  • A skilled programmer with a decent internet connection can perform the mathematical operations in a few milliseconds (e.g., less than 1 second).
  • Even a moderately fast computer would take thousands to tens of thousands of years to complete a single block.

How ​​fast are humans compared to supercomputers?

To give you an idea of ​​how slow humans are compared to supercomputers, consider this:

  • A high-performance computing cluster can perform around 1-2 exaflops (a million billion calculations per second).
  • In contrast, the average processing speed of a modern computer is in the tens or hundreds of gigahertz (gHz) range. For example:

+ Intel Core i9 processor: up to 5.3 GHz

+ NVIDIA GeForce RTX 3090 graphics card: around 1.7 GHz

Conclusion

Ethereum hashrate and mathematical operations are complex tasks that require significant computing power. While humans can perform these calculations with relative ease, we are still far behind the computational speeds available to today’s supercomputers.

As the Ethereum network continues to grow and improve, it is important to consider the potential implications for cryptography, security, and scalability. Perhaps one day we will see the development of more efficient algorithms or alternative cryptographic methods that can overcome some of these limitations. However, for now, humans will continue to play a vital role in maintaining the integrity and security of the Ethereum network.
