Becoming a node & get rewarded
The ARPA BLS-TSS Network consists of multiple groups of nodes. Within a group, each node is responsible for completing a BLS task (generating a BLS-TSS signature jointly with the other nodes of the group).
There are five types of rewards a node can earn if acted responsibly in a timely manner:
- User fee
- 0.0005 ETH paid when a user requests a random number from the ARPA Network.
- Randomness submission reward
- 4 ARPA each time a node successfully submits a randomness result.
- BLS-TSS task reward
- 4 ARPA each time a node completes a BLS-TSS task.
- DKG post-process reward
- 240 ARPA each time a node completes the DKG post-proccess task during node grouping.
- Community staking delegation reward
- 5% (up to 75,000 ARPA monthly) of the total community staking reward will be evenly distributed among all the delegated nodes. (Note: this reward can only be claimed when the node exits the network)
A minimum of 500,000 ARPA is required to become a node. After staking the minimum amount, a node can join the ARPA Network and earn rewards by correctly performing the BLS tasks.
Note: This is similar to the ETH PoS model where 32 ether must be staked to run a validator
Using AWS EC2 as an example, to ensure a steady performance, each node should be hosted on a virtual instance that meets the following specs:
- 1 vCPU
- 2G Memory
- 30G Storage
IMPORTANT: During the initial months following the release of ARPA Network on Ethereum mainnet, nodes are invite-only. This early-access period is designed to facilitate the identification of potential problems and expedite the implementation of any fixes. In this way, we can enhance the security, stability, and performance of the network before transitioning to a fully permissionless system.
After the initial period concludes, anyone with a computer that meets the above hardware requirements can host their own node permissionlessly.
You will need the following to get a node running if you do not wish to use our deployment scripts (AWS CDK):
In the meantime, if you are interested in becoming a node operator during the initial release and providing valuable feedback to help us improve, please join our waitlist, and our team will reach out to you.
