ValidatorInfo

Arthera has a number of system contracts that perform various protocol-level tasks. The choice to decouple some functionality form the main blockchain node to system contract is related to upgradeability. All System Contracts are upgradeble through a governance process, so if a vote is cast through governance to change the price of subscription plans or staking rewards, a new version of the respective contracts will be deployed without having validators upgrade their software or restart their node.


This contract is responsible for keeping a mapping between validator addresses and a validator JSON info file with additional information about the validator. The JSON file needs to be publicly available at an URl and has the following format:

{
  "name": "demo validator",
  "logoUrl": "https://imgur.net/validator_logo.png",
  "website": "https://validator.website",
  "contact": "contact@validator.website"
}

You can use the Arthera's public validator registry to publish your JSON file in Arthera's validator registry repository.

You can use the ABI to call the functions below.
