Nodes

DÆTA nodes ensure data storage, coordination and connectivity across the network.

Nodes are the backbone of the DÆTA network, providing storage capacity and computational resources.

Node Types

1. Storage Nodes

Primary function: Store and serve data.

Requirements: Stable internet connection, dedicated storage space.

2. Satellite Nodes

Primary function: Coordinate network activities.

Requirements: High availability, robust computational resources.

3. Bridge Nodes

Primary function: Connect DÆTA to other networks.

Requirements: Multi-network compatibility, enhanced security measures.

Node Selection Algorithm

def select_optimal_nodes(file_size, redundancy_factor, available_nodes):
    required_space = file_size * redundancy_factor
    suitable_nodes = [node for node in available_nodes if node.free_space >= file_size]
    
    if len(suitable_nodes) < redundancy_factor:
        raise InsufficientNodesError("Not enough suitable nodes available")
    
    selected_nodes = []
    total_selected_space = 0
    
    while total_selected_space < required_space:
        best_node = max(suitable_nodes, key=lambda n: n.reputation_score)
        selected_nodes.append(best_node)
        total_selected_space += file_size
        suitable_nodes.remove(best_node)
    
    return selected_nodes

# Usage
file_to_store = 1024  # 1GB
redundancy = 3
nodes = get_available_nodes()
optimal_nodes = select_optimal_nodes(file_to_store, redundancy, nodes)
