Flux Whitepaper Explanation

ZelCash Introduction

ZelCash focuses on enhancing the efficiency and fairness of mining processes by introducing ZelHash, an ASIC/FPGA-resistant implementation of Equihash. This project aims to address the issues surrounding specialized mining hardware, ensuring that the mining ecosystem remains accessible and equitable for a broader range of participants by resisting the advantages of ASICs and FPGAs. The core objective is to create a more decentralized and fair mining environment, preventing monopolization by entities with access to advanced hardware.

Description: What Does ZelCash Do?

ZelCash aims to create a more equitable mining environment by implementing ZelHash, a proof-of-work (PoW) algorithm designed to be resistant to ASICs and FPGAs. The project's primary goal is to prevent mining monopolization by specialized hardware, ensuring that mining remains accessible to a broader range of participants.

The methodology involves modifying the standard Equihash 125/4 algorithm to close potential compute/memory trade-offs that could be exploited in specialized hardware. This approach ensures that the mining process remains efficient and fair for general-purpose hardware like GPUs.

Problem: Why ZelCash Is Being Developed?

ZelCash is being developed to address the growing concern of mining centralization due to the dominance of ASICs and FPGAs. These specialized hardware devices can mine cryptocurrencies much more efficiently than general-purpose hardware, leading to an unfair advantage and potential monopolization by entities with access to such technology.

Current solutions like standard Equihash algorithms are insufficient in mitigating these advantages. The limitations include substantial memory requirements and inefficiencies in handling bit-length operations, which make them vulnerable to exploitation by specialized hardware. ZelCash aims to overcome these limitations through its modified ZelHash algorithm.

Use Cases

• Decentralized Mining: Ensures a fairer distribution of mining rewards by resisting ASIC and FPGA advantages.
• Enhanced Security: By preventing hardware monopolies, ZelCash promotes a more secure and decentralized network.
• Cost Efficiency: Allows miners to participate using general-purpose hardware like GPUs, reducing the entry barrier and associated costs.

How Does ZelCash Work?

ZelCash operates by implementing ZelHash, a modified version of the Equihash 125/4 algorithm. The project consists of several key components, including the Blake2B hash function and adjustments to the Equihash parameters to increase resistance to specialized hardware.

The operation can be broken down into the following steps:

1. Compute disjoint sections of length n bits using the Blake2B hash function.
2. Generate step rows from these sections and index them.
3. Identify valid solutions by ensuring the indices are pairwise distinct and meet specific XOR conditions.
4. Modify the algorithm to increase blocking factors and computational requirements, making it less efficient for specialized hardware.

Technical Details

ZelCash utilizes a proof-of-work (PoW) blockchain with a modified Equihash 125/4 algorithm. The consensus mechanism remains PoW, but with adjustments to resist ASIC and FPGA advantages. The modifications include increasing memory requirements and computational complexity to ensure fairness.

Novel technologies or methods include:

• Blake2B Hash Function: Used to generate the initial bit streams.
• Modified Equihash 125/4: Adjusted to close potential compute/memory trade-offs.
• Increased Blocking Factor: Enhances resistance to specialized hardware by making later computation rounds more costly.
