1. Abstract

Gravity Coin (GRA) represents a paradigm shift in decentralized payments. Built on a robust Proof of Authority (PoA) consensus, Gravity Coin offers a secure, high-speed blockchain solution designed for instant, low-cost global transactions. This whitepaper outlines the technical architecture, economic model, and roadmap for the Gravity ecosystem.

2. Introduction

Traditional blockchains often suffer from the "trilemma" of scalability, security, and decentralization. Gravity Coin addresses these issues through a custom-built, high-performance architecture that prioritizes user experience and security through a trusted validator network.

2.1 The Problem

High gas fees and slow confirmation times prevent mass adoption of cryptocurrencies for daily payments. Users require a system that is as fast as a credit card swipe but as secure as a bank vault.

2.2 The Solution

Gravity Coin implements a 3-second block time and a highly optimized PoA consensus mechanism to achieve near-instant finality. With fees costing a fraction of a cent, GRA is viable for micro-transactions and large settlements alike.

3. Technology

3.1 Proof of Authority (PoA)

Unlike energy-intensive Proof-of-Work (PoW) chains, Gravity Coin uses a Proof of Authority consensus. Blocks are validated by trusted nodes, ensuring maximum efficiency, security against 51% attacks, and consistent block times.

3.2 Custom Layer-1 Architecture

Gravity Coin is built on a custom Golang-based engine designed for speed and simplicity. It utilizes a lightweight transaction structure and secp256k1 address format (`gra1...`) to ensure human-readability and error reduction.

3.3 Network Specifications

4. Tokenomics

The economic model of Gravity Coin is designed to reward long-term holders and active participants while ensuring scarcity. The total supply is fixed at 100,000,000 GRA.

4.1 Allocation
