Validators

Introduction

Metanovaverse is based on Tendermint Core, which relies on a set of validators that are responsible for committing new blocks in the blockchain. These validators participate in the consensus protocol by broadcasting votes which contain cryptographic signatures signed by each validator's private key.

Validator candidates can bond their own staking tokens and have the tokens "delegated", or staked, to them by token holders. MNV is Metanovaverse's native token.

Validators and their delegators will earn MNV as block provisions and tokens as transaction fees through execution of the Tendermint consensus protocol. Initially, transaction fees will be paid in MNV but in the future, any token in the Cosmos ecosystem will be valid as fee tender if it is whitelisted by governance. Note that validators can set commission on the fees their delegators receive as additional incentive.

Validators receive the highest rewards of all participants for preserving the foundation of the chain. The Metanovaverse ecosystem has a total inflation rate of 20%, so Validators earn 20% additional MNV tokens per annum on top of the gas fees paid by smart contract users.

Validators are encouraged to acquire as many tokens as possible for their nodes, because see real earnings potential, one should optimize for server costs and the annual inflation rate. Starting validation with a small amount can result in little-to-no rewards to even cover expenses.

Validators that double sign, are frequently offline, or do not participate in governance, can have their staked MNV (including MNV of users that delegated to them) slashed. The penalty depends on the severity of the violation.

Hardware

Validators should set up a physical operation secured with restricted access. A good starting place, for example, would be co-locating in secure data centers.

Validators should expect to equip their datacenter location with redundant power, connectivity, and storage backups. Expect to have several redundant networking boxes for fiber, firewall and switching and then small servers with redundant hard drive and fail-over. Hardware can be on the low end of datacenter gear to start out with.

We anticipate that network requirements will be low initially. Bandwidth, CPU and memory requirements will rise as the network grows. Large hard drives are recommended for storing years of blockchain history.

Supported OS

For now, we officially support machines running Ubuntu Linux with the following architectures:

• linux/arm64

• linux/x86_64

Minimum Requirements

To run mainnet or testnet validator nodes, you will need a machine with the following minimum hardware requirements:

• 4 or more physical CPU cores

• At least 1TB of SSD disk storage

• At least 32GB of memory (RAM)

• At least 100mbps network bandwidth

As the usage of the blockchain grows, the server requirements may increase as well, so you should have a plan for updating your server as well.

Get Involved

Validators earn from Block rewards created on chain and receive delegation from users
