# Introduction

This guide provides detailed steps to register an ENS domain on the **Polygon** and **Bloxberg** blockchains. The ENS implementation on these blockchains has been modified to simplify payment processes and domain duration settings. The payment is fixed at 100 coins (ECLD for Polygon and ETNY for Bloxberg), and the registration duration is effectively infinite (584,554 years). However, the input duration must be more than 28 days (in seconds) for validation purposes.
