Relay Nodes

November 21, 2023 - Around 3 mins mins to read

Relay nodes are an important component in blockchain networks that help maintain efficient communication pathways and reduce the number of hops required to send messages across the network.

In the context of blockchain technology, a node refers to a computer or device that participates in a decentralized database. These nodes are distributed across different locations to ensure the decentralized operation of the network. They form the foundation of blockchain technology and contribute to the creation of a unified system within the blockchain. The more nodes supporting the decentralized infrastructure, the more resilient the blockchain becomes.

Relay nodes are a specific type of node within a blockchain network that serve to minimize system noise and improve efficiency. They collect protocol messages from participating nodes and other connected relay nodes. These relay nodes perform duplication checks, validate signatures, and undertake other necessary steps before transmitting only valid messages. By positioning relay nodes near internet exchange points, propagation time is reduced, making the network more efficient. The operation of relay nodes is open to anyone who wishes to contribute to the network.

Besides blockchain networks, relay nodes are commonly used in wireless networks in the field of information technology. They significantly enhance the efficiency of wireless networks by dividing long single-hops into shorter two-hops, rather than performing a single long hop from one node to another. This technique, known as relay routing, has proven to be highly effective in reducing path loss in certain cases. It depends on the technology, path loss models, and environment.

Within the Algorand platform, relay nodes play a crucial role in maintaining interconnection between all other types of nodes. They communicate with participation nodes and other relay nodes using network messages. These messages undergo deduplication, signature checks, and other validation processes before being re-propagated within the system. This process significantly reduces transmission time and ensures the integrity of the network.

A relay node uses the same software as a non-relay node but requires additional configuration specifications to be set. The fact that a relay node is essentially the same as any other node is one of the advantages of Algorand’s decentralized network implementation. Currently, the distinction between a relay node and a non-relay node is made by configuring the node to actively listen for connections from others and advertising itself via DNS SRV records. It is also possible to set up a relay for a personal network that does not require DNS entries. To be considered a valid relay node, the following conditions must be met:

  • The node is configured to receive inbound traffic on a publicly open port.
  • Algorand’s SRV records for a given network contain the node’s public IP address and assigned port.

Relay nodes must be capable of supporting a large number of connections and handling the processing burden associated with the data traveling to and from these connections. They are critical for maintaining efficient communication within the blockchain network.

In conclusion, relay nodes are network hubs within blockchain networks that help establish efficient communication pathways and reduce the number of hops required to send messages. They play a crucial role in maintaining the decentralized operation of the blockchain network, improving efficiency, and reducing transmission time. Whether in blockchain networks or other wireless networks, relay nodes have proven to be effective in enhancing communication and reducing path loss. Algorand’s decentralized network implementation allows for anyone to operate relay nodes and contribute to the network’s resilience and efficiency.
