Hathor Whitepaper Explanation

#424

Hathor is a scalable and decentralized cryptocurrency platform that merges DAG and blockchain technologies to enhance transaction throughput and network security.

Hathor Introduction

Hathor is a transactional consensus platform that merges the features of Directed Acyclic Graph (DAG) and blockchain technologies to address scalability and decentralization issues in distributed ledger networks. Unlike traditional blockchain that can struggle with high transaction volumes, Hathor combines a chain of mined blocks within a DAG of transactions, creating a system that remains efficient regardless of the number of transactions per second. The primary goal is to solve the constraints of existing blockchain systems, making it a more scalable and decentralized alternative.

Description: What Does Hathor Do?

Hathor is designed to be a scalable and decentralized cryptocurrency platform that combines elements of both DAG and blockchain technologies. The main objectives of Hathor include enhancing scalability, maintaining decentralization, and preventing spam attacks on the network.

The methodology to achieve these objectives involves creating a hybrid architecture where both transactions and blocks are linked to form a DAG. Blocks are further connected to both other blocks and transactions, maintaining a blockchain structure within the DAG. This hybrid approach allows the system to handle a high volume of transactions efficiently.

Problem: Why Hathor Is Being Developed?

Hathor is being developed to address the limitations of existing blockchain technologies, specifically their issues with scalability, centralization, and susceptibility to spam attacks. These problems impact the efficiency and trustworthiness of cryptocurrencies, affecting a wide range of users and applications.

Current solutions like Bitcoin and Iota have their own limitations. Bitcoin struggles with low transaction throughput, while Iota requires a minimum transaction volume to function correctly, relying on a central coordinator under low volume conditions. Hathor aims to provide a balanced solution that performs well under varying transaction loads without centralization.

Use Cases

  • Microtransactions: Efficiently handles small transactions quickly, making it ideal for IoT and mobile devices.
  • Spam Prevention: Adjusts transaction difficulty to prevent spam, enhancing network security.
  • High-Volume Transactions: Scales efficiently with transaction volume, making it suitable for high-frequency trading and other applications requiring rapid transaction processing.

How Does Hathor Work?

Hathor consists of a hybrid system that integrates both DAG and blockchain elements. Its architecture includes transactions and blocks that are connected to form a Directed Acyclic Graph (DAG). Blocks are also connected to transactions, creating a blockchain within the DAG.

Steps:

  1. Transaction Creation: Transactions are created by users and include inputs and outputs.
  2. Proof-of-Work: Both transactions and blocks must solve a proof-of-work puzzle based on their weight.
  3. Verification: Transactions verify previous transactions, and blocks verify both transactions and other blocks.
  4. DAG Formation: This verification process forms a DAG of verifications and a DAG of funds.
  5. Block Mining: Miners generate new blocks, which are then verified and added to the network.
  6. Spam Prevention: The difficulty of transaction creation adjusts dynamically to prevent spam attacks.

Technical Details

Hathor utilizes a combination of DAG and blockchain technologies to create a scalable and secure network. It employs proof-of-work mechanisms for both transactions and blocks, adjusting the difficulty levels to balance network load and prevent spam.

Innovations:

  • Hybrid DAG-Blockchain Architecture: Combines the benefits of both technologies.
  • Dynamic Difficulty Adjustment: Adjusts the difficulty of transaction creation to prevent spam.
  • Decentralized Hash Rate: Both miners and users contribute to the network's hash rate, promoting decentralization.

Hathor Tokenomics: Token Utility & Distribution

Hathor's tokenomics involve the use of tokens within its ecosystem for transaction fees and rewards for miners. The tokens are generated through block mining and are used to incentivize network participants.

The distribution and allocation strategy include generating new tokens through mining blocks, which are distributed to miners as rewards. The economic model focuses on maintaining a stable token supply while incentivizing network security and participation.
