# INTRODUCTION
> .bit to the crypto world is what Phone/Email to the Internet.
.bit is a blockchain-based, open source, decentralized cross-chain account
system that provides a worldwide unique naming system with a .bit suffix that
can be used in different scenarios, such as cryptocurrency transfer, domain name
resolution, identity authentication, etc.
.bit is the first decentralized account system with broad compatibility,
allowing users to register and manage their .bit accounts with any public chain
address or even email.
The core elements of a .bit account contain the owner/manager, and the record
(i.e. the data associated with). Unlike ENS, the owner/manager of .bit can be
any public chain private key or even email; unlike DNS, .bit supports any type
of record.
The structure of a .bit account is as follows:
.bit is a decentralized application running on Nervos CKBopen in new window.
.bit accounts and related records are stored on the permissionless blockchain.
Nervos CKB is a PoW public chain with a highly open architecture using the UTXO
model.
.bit has five main components:
1. Core Protocol
This refers to a series of Lock Scripts and Type Scripts deployed on Nervos
CKB. They define .bit accounts and the related operational standards for
.bit accounts and are the concrete implementations of the .bit core
protocols.
2. Keeper
Keeper is a set of off-chain programs that can be run by anyone without
permission, and is responsible for triggering a series of transactions that
conform to the core protocol. Running a Keeper earns .bit system rewards.
3. Resolution Service
It resolves the global state of .bit based on the transactions on Nervos CKB
and provides account resolution service to the public in the form of an
interface.
4. Client SDK
Includes SDKs in various languages to simplify the integration of mobile
wallets, web wallets, server wallets and other .bit-related applications.
5. Dapp UI
Users ultimately use various features of .bit through a variety of
application interfaces. These applications can be used directly in the
browser or can be integrated into popular wallet software.
The source code for all the components above can be found on our Github
repositoryopen in new window. Also, developers can implement their Keeper,
Resolution Service, Client SDK, and Dapp UI based on the Core Protocol.
