This transparency is essential for validating the network’s integrity and ensuring compliance with established protocols by all participants.
The absence of Archival Full Nodes would result in fragmented historical data within the blockchain, impeding the network’s capacity to operate as a transparent and trustless system.
Pruned Full Nodes
Pruned Full Nodes are designed to optimize storage resources by retaining solely the most recent blockchain data while upholding the responsibility of validating transactions and upholding network security.
Conversely, Archival Full Nodes maintain a complete historical record of all transactions ever conducted on the blockchain.
Although this approach offers a comprehensive transaction history, it mandates a considerably larger storage capacity compared to Pruned Full Nodes.
Pruned Full Nodes offer distinct advantages in terms of efficiency as they necessitate lesser storage space and bandwidth, rendering them more accessible to users with limited resources.
These nodes fulfill a critical function in transaction validation by ensuring that only legitimate transactions are appended to the blockchain, thereby fortifying the overall integrity and security of the network.
Masternodes
Masternodes are specialized nodes that offer advanced services to the blockchain network, such as enabling instant transactions and upholding network stability.
These nodes play a critical role in supporting the network’s efficiency and security through a range of functions.
Plus transaction processing, masternodes engage in activities like validating and authenticating transactions to maintain the integrity of the blockchain.
Unlike regular nodes, which primarily verify transactions, masternodes also play a role in generating proposals for system enhancements and participating in voting processes concerning crucial decisions that impact the network’s advancement.
This level of active engagement distinguishes them from other node types and underscores their significant contribution to the blockchain ecosystem.
Authority Nodes
Authority Nodes play a crucial role in Proof-of-Authority (PoA) blockchain networks, as they are tasked with validating transactions and upholding consensus based on their identity and reputation.
Typically, these nodes are chosen by network participants or designated entities because of their established credibility and trustworthiness.
By utilizing their recognized identities, Authority Nodes play a significant part in preventing malicious activities and ensuring the network’s integrity.
Their duties include verifying valid transactions and aiding in reducing the risks associated with fraud or attacks within the blockchain ecosystem.
This approach enhances the overall security and effectiveness of PoA networks, creating a more dependable environment for transactions and data integrity.
Staking Nodes
