dYmension is a high-performance execution environment for running application logic [1]. It scales through the separation of resource consumption, similar to traditional web infrastructure. At the same time, it also allows applications to insert themselves into a connected, decentralized and trust-minimized environment. dYmension is an infrastructure that combines traditional reliable Web2 instances with the ownership and connectivity benefits of the decentralized Internet [1].

dYmension adopts a modular blockchain architecture design to decouple the different functions of a "single" blockchain to improve performance, efficiency and scalability. In a traditional monolithic blockchain, transaction execution, state settlement, data processing, and consensus on the canonical history of the chain are handled. In dYmension, each application is its own execution environment, and the dYmension hub is the settlement layer [1].

dYmension introduces a multi-layer blockchain protocol that provides powerful tools for building and deploying permissionless application-specific rollups. These applications are called RollApps. dYmension can be seen as the center and factory for these applications. These RollApps can choose to integrate various data availability providers based on security and cost considerations [2].

In dYmension’s protocol, a checkpoint is defined as a block batch published to the DA layer, and the corresponding state root published to the settlement layer. The availability and immutability of data after checkpointing is very important, as corrupted data may cause inconsistent state between RollApp nodes. When deploying RollApp, relying on a specific DA solution is one of the very important considerations [3].

dYmension implements a shared security model that becomes more secure as more applications are deployed. The execution layer of dYmension is an autonomous execution environment. The application deployed on dYmension is RollApp and has its own autonomous rights. They can enjoy the benefits of building their own blockchain, such as having their own native network fee token and fully flexible application logic [4].

In addition, dYmension also supports various execution environments, driving RVM instances with the exact context of a given transaction, resulting in deterministic output [5].dYmension will also embed a local automated market maker (AMM) into the settlement center to enable shared liquidity and shared security. As the infrastructure of RollApp, the embedded AMM is not limited to the use of RollApp [5].

Overall, dYmension is a blockchain protocol with a modular architecture that achieves performance optimization and decentralized deployment of applications by separating resource consumption and introducing the concept of RollApp. It provides powerful tools and technologies that allow developers to build and deploy permissionless applications and select data availability providers based on security and cost considerations.
