Validator Frequently Asked Questions
What is a validator?
A validator is a computer that runs a software program to verify transactions that are added to the Velas blockchain. A validator can be a voting validator or a non voting validator. To learn more, see what is a validator.
What is an RPC node?
An RPC node is also a computer that runs the validator software. Typically, an RPC node does not vote on the network. Instead the RPC node's job is to respond to API requests. See what is an rpc node for more information.
What is a cluster?
For a definition and an overview of the topic, see what is a cluster. Velas maintains several clusters. For details on each, see Velas clusters.
What is Delegated Proof of Stake?
Delegated Proof of Stake (DPoS) is a consensus mechanism, variation of the classic Proof of Stake (PoS) system. Velas is a DPoS blockchain. To read more, see Delegated Proof of Stake.
What is Proof of Work? Is running a Velas validator the same as mining?
No, a Velas validator uses Delegated Proof of Stake. It does not use Proof of Work (often called mining). See Proof of Work: For Contrast.
Who can operate a validator?
Anyone can operate a validator. All Velas clusters are permissionless. A new operator can choose to join at any time.
Is there a validator set or limited number of validators that can operate?
No, all Velas clusters are permissionless. There is no limit to the number of active validators that can participate in consensus. Validators participating in consensus (voting validators) incur transaction fees for each vote.
What are the hardware requirements for running a validator?
Can I run my validator at home?
Anyone can join the cluster including home users. You must make sure that your system can perform well and keep up with the cluster. Many home internet connections are not suitable to run a Velas validator. Most operators choose to operate their validator in a data center either by using a server provider or by supplying your own hardware at a colocation data center.
See the validator requirements for more information.
What skills does a Velas validator operator need?
See Velas validator prerequisites.
