WALCHAIN – A HIGH-PERFORMANCE LAYER 1 BLOCKCHAIN FOR SUPERWAL

Walchain is a cutting-edge Layer 1 blockchain designed to power Web3, DeFi, SocialFi, and real-world asset (RWA) applications. By combining the Stellar Consensus Protocol (SCP) with Zero-Knowledge Rollups (ZK-Rollups), Walchain delivers high throughput, low fees, and robust security without relying on Ethereum Virtual Machine (EVM) compatibility.

1. Walchain Architecture

1.1. Stellar Consensus Protocol (SCP) – The Consensus Mechanism

Overview of SCP in Walchain

The Stellar Consensus Protocol (SCP) is a Byzantine Fault Tolerant (BFT) consensus algorithm that enables decentralized agreement without the energy-intensive Proof of Work (PoW) or staking-heavy Proof of Stake (PoS). In Walchain, SCP uses Quorum Slices—customizable sets of trusted validator nodes—to ensure fast, secure, and decentralized transaction validation.

How SCP Operates in Walchain

1. Transaction Proposal (Nomination Phase):

   • Validator nodes propose transactions and share state data across the network.

   • Each node defines its own Quorum Slice, a trusted subset of validators it relies on.

   • Transactions are authenticated using ECDSA or Schnorr signatures.

2. Voting & Consensus (Ballot Protocol Phase):

   • Validators vote on proposed transactions based on their Quorum Slice.

   • A transaction is finalized when at least 66% of a Quorum Slice agrees.

   • If consensus isn’t reached, additional voting rounds occur until agreement is achieved.

SCP Workflow in Walchain

1. A node submits a transaction.

2. The Quorum Slice achieves 66% consensus.

3. The transaction is recorded on the blockchain.

Performance Highlights

• Baseline Throughput: Over 2,000 transactions per second (TPS).

• Scalability: Tens of thousands of TPS with ZK-Rollup optimization.

• Applications: Ideal for Web3, DeFi, and SocialFi use cases.

1.2. Quorum Slice Structure and Security

In SCP, each validator node forms its own Quorum Slice, trusting only a specific group of nodes. This design enhances security by preventing Sybil attacks—malicious actors cannot influence consensus without approval from a trusted subset.

Example Quorum Slice Configuration (JSON):

{
  "node_id": "walchain-validator-1",
  "quorum_slices": [
    ["walchain-validator-2", "walchain-validator-3"],
    ["walchain-validator-3", "walchain-validator-4"]
  ]
}

• A transaction requires 66% agreement within the Quorum Slice to be validated.

SCP vs. Other Consensus Mechanisms

• Compared to PoW (Bitcoin): SCP is faster and more energy-efficient.

• Compared to PoS (Ethereum 2.0): SCP avoids staking requirements, leveraging flexible Quorum Slices.

• With ZK-Rollup: Walchain surpasses traditional SCP implementations (e.g., Stellar) in throughput.

2. Walchain Deployment and Configuration

2.1. Hardware Requirements for Validator Nodes

Minimum Configuration

• CPU: 8 cores

• RAM: 32 GB

• Storage: 1 TB SSD (NVMe)

• Bandwidth: 100 Mbps

2.2. Setting Up a Validator Node

Installation on Ubuntu

sudo apt update && sudo apt install stellar-core -y

Configuration

Edit the configuration file:

nano /etc/stellar/stellar-core.cfg

Example configuration:

[DATABASE]
TYPE="sqlite"
DATABASE="walchain.db"

[QUORUM_SET]
VALIDATORS=[
  "validator1.walchain.io",
  "validator2.walchain.io",
  "validator3.walchain.io"
]

[HISTORY]
HISTORY.walchain_pubnet="aws://walchain-history"

Starting the Node

stellar-core --new-db         # Initialize database
stellar-core --forcescp       # Sync consensus state
stellar-core --start          # Launch the node

ZK-Rollup Integration

To enable ZK-Rollup support, integrate ZK libraries (e.g., libsnark) into the Stellar Core codebase.

3. Ecosystem Integration

3.1. Asset Bridge for Cross-Chain Connectivity

How It Works

• Deposit: Tokens are locked on the source chain (e.g., Ethereum) and minted on Walchain.

• Withdrawal: Walchain tokens are burned, unlocking the original tokens on the source chain.

zk-SNARKs for Validation (Rust Example)

use bellman::groth16::{Proof, Verifier};
use pairing::bls12_381::{Bls12, Fr};

fn verify_proof(proof: Proof<Bls12>) -> bool {
    let verifier = Verifier::<Bls12>::default();
    verifier.verify(&proof)
}

Bridge API Example

{
  "source_chain": "Ethereum",
  "destination_chain": "Walchain",
  "transaction_id": "0xABC123...",
  "status": "pending"
}

Benefits

The Asset Bridge ensures seamless interoperability with major blockchains, enhancing DeFi and Web3 functionality.
