VICE Layer Architecture

The VICE layers form the foundation of the SKENAI blockchain architecture, providing a structured approach to blockchain governance and operation.

Core Layers

• Value: Economic incentives and token mechanisms
• Identity: Authentication and authorization systems
• Consensus: Agreement protocols and validation
• Execution: Smart contract and transaction processing

Each layer operates independently but communicates with adjacent layers through standardized interfaces.

Implementation Example

Here's a simple example of how the VICE layers interact:

class ViceArchitecture {
  constructor() {
    this.valueLayer = new ValueLayer();
    this.identityLayer = new IdentityLayer();
    this.consensusLayer = new ConsensusLayer();
    this.executionLayer = new ExecutionLayer();
  }

  processTransaction(tx) {
    // Identity layer verifies the sender
    const sender = this.identityLayer.verifySender(tx.sender);
    
    // Consensus layer validates the transaction
    const isValid = this.consensusLayer.validate(tx);
    
    if (isValid) {
      // Execution layer processes the transaction
      const result = this.executionLayer.execute(tx);
      
      // Value layer updates balances and rewards
      this.valueLayer.updateState(tx, result);
      
      return result;
    }
    
    return null;
  }
}

Benefits

The VICE architecture provides several key benefits:

1. Modularity: Each layer can be upgraded independently
2. Scalability: Specialized processing for different types of operations
3. Security: Clear separation of concerns enhances security
4. Flexibility: Supports multiple consensus mechanisms and execution environments

Layer Details

Value Layer

The Value layer handles all economic aspects of the blockchain, including:

• Token issuance and management
• Fee structures and payment processing
• Reward distribution for validators and contributors
• Economic incentive mechanisms

Identity Layer

The Identity layer manages authentication and authorization, including:

• Public key infrastructure
• Account management
• Reputation systems
• Access control mechanisms

Consensus Layer

The Consensus layer ensures agreement on the state of the blockchain:

• Block validation and production
• Validator selection and rotation
• Fork choice rules
• Finality mechanisms

Execution Layer

The Execution layer processes transactions and smart contracts:

• Virtual machine for smart contract execution
• State transitions
• Transaction processing
• Data storage and retrieval
