Overview

Dymension is a decentralized Delegated Proof-of-Stake L1 blockchain designed to support fast and easily deployable app-chains known as RollApps. RollApps serve as the interactive applications within the Dymension ecosystem, enabling the creation of games, DeFi projects, NFT ventures, and more. Acting as the backbone, Dymension coordinates the ecosystem, while decentralized data availability networks function similarly to databases, providing short-term data storage and security verification.

Key Components:

RollApps: The front-end interactive applications that users engage with.
Dymension Hub: The back-end infrastructure that secures RollApps and facilitates user interactions, such as deposits, plays, and withdrawals. It also includes a decentralized exchange for trading RollApp tokens.
Data Availability Networks: Decentralized networks that provide data availability, ensuring the security and integrity of RollApps.

Features:

Security: RollApp funds are secured by Dymension validators.
Bridging: RollApps can interconnect and link to the broader crypto economy through a single IBC connection.
Liquidity: The Dymension Hub includes an Automated Market Maker (AMM) that supports efficient asset routing, price discovery, and shared liquidity across the ecosystem.

Dymension operates like an internet service provider, facilitating seamless integration and connectivity for RollApps, and reducing blockchain deployment time to mere minutes.

Standardization: Dymension emphasizes the importance of standardization for compatibility, security, and efficiency. It maintains an on-chain registry for approved Dymension RollApp Standards (DRS), which developers can use or customize. Custom standards require on-chain governance approval before being integrated into the core protocol and associated tools.

This structure ensures that Dymension remains a robust, secure, and efficient platform for developing and deploying decentralized applications.
