Node Requirements
A Dusk node can take many different roles, from being a Provisioner and participating in consensus, to proving transactions, to storing historical data. The node is designed to be efficient, decentralized, and able to run on a wide-variety of hardware and platforms.
DUSK Requirement
To run a Dusk provisioner, at least 1000 DUSK must be staked.
Why stake?
Dusk uses a pure proof-of-stake algorithm to provide sybil-resistance and as such it is a cornerstone of Dusk’s security and consensus mechanism. By staking DUSK, participants actively contribute to the network’s integrity.
Stakers have the right to participate in the Succinct Attestation and accrue rewards for generating blocks and participating in block validation activities. These rewards are an incentive for creating blocks and voting, and compensate users for locking their assets while their node performs such operations.
Software
We recommend using a stable operating system with long-term support, such as Ubuntu 22.04 or Debian Bookworm.
Hardware
The node software has been tested on x86-64/AMD64 and ARM architectures.
Provisioner Specifications
These specifications are set to comfortably accommodate provisioner and full nodes, with limited proving capabilities.
For increased network throughput, the node benefits from highly performant single-threaded performance.
| CPU | RAM | Storage | Network Connection |
|---|---|---|---|
| 2 cores; 2 GHz | 4 GB | 50 GB | 10 Mbps |
Prover Specifications
Prover requirements are dependant on the amount of workers a server can run in parallel. Single-threaded performance is key to generate proofs as quickly as possible.
Minimum
| CPU | RAM | Storage | Network Connection |
|---|---|---|---|
| 4 cores; +2 GHz | 8 GB | 20 GB | 20 Mbps |
Per Worker
The specifications listed below are per worker.
| CPU | RAM | Storage | Network Connection |
|---|---|---|---|
| 1 core; +2 GHz | 1 GB | 2 GB | 5 Mbps |
Archiver Specifications
Archivers store and provide access to historical data. As such, they benefit from the capability to process multiple concurrent data requests, fast internet connectivity, and enough storage. The following specs are a reference point for archivers. For an archiver, the beefier the configuration, the higher the amount of concurrent requests they can handle.
| CPU | RAM | Storage | Network Connection |
|---|---|---|---|
| 8 cores; 2 GHz | 16 GB | 250 GB | 100 Mbps |
Networking
Dusk makes use of the ultra-efficient P2P network protocol Kadcast. As such, the internet service requirements are relatively low, but they should be symmetrical and stable, with low latency.
Port Forwarding
For the node to be accessible to the outside world, a number of ports need to be open to allow for inbound and outbound messages.
- 9000/udp: Required for Kadcast consensus messages.
- 8080/tcp: Optional HTTPS API for querying the node.
Server Security
Maintaining a secure and stable node is paramount for the proper functioning of Dusk. We advise using a firewall, locking down unused APIs, performing regular updates and using a static IP for an uninterrupted service.
