"High-Performance EVM Network Powered by QBFT Consensus for Instant Finality."

The blockchain industry faces a trilemma of scalability, security, and decentralization. While existing Layer 1 solutions have made significant strides, many still suffer from probabilistic finality, high latency, and fluctuating gas fees that hinder enterprise adoption and high-frequency DeFi applications.

Riche Chain introduces a next-generation Layer 1 blockchain fully compatible with the Ethereum Virtual Machine (EVM), utilizing the Quorum Byzantine Fault Tolerance (QBFT) consensus mechanism. This architecture achieves instant finality, zero block reorganization, 3-second block times, and a high-throughput gas limit of 25,000,000, creating an ideal environment for financial institutions and decentralized applications requiring absolute transaction certainty.

1. Introduction

1.1 The Problem

Current blockchain infrastructures often rely on Proof of Work (PoW) or standard Proof of Stake (PoS) variants that introduce "Probabilistic Finality." In these systems, a transaction is not immediately permanent; users must wait for multiple confirmations to ensure a block is not "orphaned" or reorganized (reorg). This latency creates uncertainty for:

Real-time Payments Merchants cannot accept crypto instantly without risk of double-spending or rollback.
DeFi Arbitrage Reorgs can cause failed trades, massive slippage, or MEV exploitation.
Supply Chain Data integrity requires immediate, immutable timestamping which PoW/PoS cannot instantly guarantee.

1.2 The Riche Chain Solution

Riche Chain addresses these challenges by implementing QBFT (Quorum Byzantine Fault Tolerance). Unlike Nakamoto consensus (longest chain rule), QBFT offers Immediate Finality. Once a block is minted and signed by the validator quorum, it is final. It cannot be reverted. This feature, combined with low transaction costs and EVM compatibility, positions Riche Chain as a robust alternative for both Web3 developers and traditional enterprises.

2. Technical Architecture

2.1 Consensus Mechanism: QBFT

Riche Chain utilizes the IBFT 2.0 (Istanbul BFT) variant known as QBFT. It requires a supermajority (>= 2/3) of validators to sign a block before it is committed to the chain.

Validators: A set of authorized nodes responsible for validating transactions and creating blocks.
Supermajority: A block is committed only when >= 2/3 of validators sign it.
Zero Reorganization: Since a block requires a supermajority to be created, forks are mathematically impossible under normal operation. This guarantees that block n is the permanent predecessor of block n+1.

3. Economic Model (Tokenomics)

3.1 Native Asset: RIC

The RIC coin is the lifeblood of the network. It serves two primary functions:

Gas Fees

Used to pay for computation and storage on the network. The fee market is designed to be ultra-low cost to encourage high-volume usage and micro-transactions.

Governance

RIC holders will eventually participate in on-chain governance to vote on network upgrades, parameter adjustments, and validator elections in future phases.

3.2 Supply & Distribution

Total Supply 100,000,000 RIC
Ticker RIC
Inflation Model
Deflationary mechanism via fee burning (EIP-1559 implementation planned) or fixed supply model to ensure long-term value retention.

4. Ecosystem & Utility

4.1 For Developers

Riche Chain provides a "Build-First" environment with robust infrastructure ready from Day 1:

Public RPC High availability endpoints for seamless dApp connectivity.
WebSocket (WSS) Real-time event listening support for dynamic interfaces.
Block Explorer Full transparency and verification tools via RicheScan.

4.2 Use Cases

DeFi & High-Frequency Trading

With 3-second block times and instant finality, arbitrage bots and trading protocols can operate without the risk of failed trades due to reorganization.

GameFi & Metaverse

In-game assets are transferred instantly. No more waiting for "12 confirmations" before a player receives their item.

Enterprise Solutions

Supply chain and identity management systems require the absolute data certainty that QBFT provides, ensuring audit trails are immutable immediately.
