Participation Node

November 21, 2023 - Around 3 mins mins to read

In order to understand participation nodes in a blockchain network, it is important to first grasp the concept of nodes. In the context of blockchain, nodes are electronic devices connected to the network with an IP address. They serve as communication endpoints, meaning that any user or program wanting to connect with the blockchain must do so through nodes. This makes nodes vital for redistributing communication within the network.

One of the defining characteristics of blockchain networks is their decentralized nature. This means that anyone can operate a node, as there is no central authority controlling access. Public blockchains aim to be dynamic and decentralized, with nodes continuously joining and leaving the network. Additionally, certain blockchains may allow nodes to operate without participating in the consensus process. For example, Delegated Proof-of-Stake (dPoS) blockchains choose validators through stakeholder voting. However, not everyone has the necessary time, knowledge, or expertise to manage a node.

In the specific case of Algorand, a blockchain network, there are two types of nodes: relay nodes and participation nodes. Relay nodes act as network hubs, efficiently transmitting protocol messages between participating nodes. They play a crucial role in maintaining network connectivity and facilitating communication between nodes.

On the other hand, participation nodes are responsible for the consensus process in Algorand. They introduce and validate new blocks in the blockchain. To perform these tasks, participation nodes use participation keys, which are stored on the nodes themselves. The participation keys are used to sign consensus protocol communications.

In order to connect with each other, participation nodes in Algorand rely on the consensus mechanism and the coordination of relay nodes. To become a participation node, network participants must stake ALGO (the native cryptocurrency of Algorand) and generate a valid participation key. The consensus method used in Algorand is called Pure Proof-of-Stake (PPoS), which involves a two-phase block creation process consisting of proposing and voting.

While relay nodes coordinate the participation nodes and enable communication between them, they do not directly engage in the proposing and voting processes. It is the participation nodes, authorized by the user’s participation key, that propose and vote on blocks on behalf of the user’s stake within the consensus process. A single participation node can represent multiple users if their relevant participation keys are placed within it.

Running participation nodes is open to anyone in the Algorand network. As long as enough of them operate the consensus process honestly, the Algorand blockchain will remain secure and intact, even if all relay nodes are compromised.
