Nodes & Delegators

hashtag
Nodes

Nodes are fundamental to the operations of the Brainstems protocol, providing the computational and technical infrastructure necessary to facilitate DeFIM and model optimization. There are two primary types of nodes within the Brainstems network: Computation Nodes and Aggregation Nodes.

Computation Nodes

Computation Nodes are responsible for executing the computational tasks involved in training AI models through DFL. These nodes receive encrypted data contributions from Federation Partners and perform the necessary computations to train the models based on the provided data. Computation Nodes process the data to train the foundation model generate model weights that are passed to Aggregation Nodes.

hashtag
Aggregation Nodes

Aggregation Nodes play a pivotal role in the optimization and refinement for the final intelligence output within a Brainstems deployment. Once weights are passed along for optimization, Aggregation Nodes combine the model weights, leveraging techniques such as federated averaging to enhance the overall performance and accuracy of the trained models. Aggregation Nodes create a robust and high-quality AI model that is specifically trained for Federated Partner use-cases and reflects the collective intelligence of the Brainstems network.

Staking, Rewards and Token Emissions

In order to be eligible to participate in an active Brainstems Deployment, nodes must stake at least 10,000 STEMS and enter the active node set. STEMS can be self-staked, delegated from Brainstems community members, or provided to the node via the Brainstems Foundation Delegation Program.

Rewards can be broke down into a few parts, as they occur at various stages of a Deployment Lifecycle. First, upon completion of the required training within a Brainstems Deployment, nodes will submit a proof to the Brainstems Validator in order to unlock the escrowed financing pool created by Stewards. This pool of funds is designed to compensate Nodes for the computation costs incurred throughout the training process.

All Federation Partners are required to pay subscription fees in order to access the intelligence created through their deployment. These fees are distributed across the various stakeholders within the Brainstems ecosystem, as outlined in Tokenomics. Nodes will earn 15% of the subscription fees paid by partners.

In additional to these rewards, Nodes will also passively earn STEMS through Node Emissions, as an incentivize for helping bootstrap and scale the Brainstems network.

Delegators

While Stewards are the financial underbelly of Brainstem deployments, Delegators provide the financial backing necessary for Nodes to participate in the network.

As shown above, Delegators can contribute stake to nodes in exchange for $STEMS tokens and deployment revenue.

Nodes compete to acquire $STEMS stake and computationally outperform other nodes, in order to increase their chances of being selected for actively deployments Brainstems. Thus, Nodes are incentivized to provide a % of their revenue to Delegators in exchange for stake. Nodes will be able to choose how the amount of rewards they are willing to give up; however, we predict 5-15% to be a competitive rate.

Delegators may use a variety of factors to choose which nodes to delegate to, including:

  • % of rewards

  • Reputation Score

  • Number of Active Deployments

  • % of existing stake

All metrics related to node performance will be provided within the Brainstems Node Activity Monitor, for Delegators to monitor.

Upon delegating to a node, delegated stake is locked until the next epoch when rewards are emitted (current estimate: ~30 days). If stake is undelegated during the epoch, it will automatically unlock at the end of the epoch and $STEMS will be returned to the delegators wallet.
