Dymension is a modular Layer-1 blockchain platform that supports the creation and deployment of new application-specific blockchain networks called RollApps. Blockchains like Ethereum and Solana are effective general-purpose networks that can support decentralized applications (DApps). However, due to the constraints of the Proof of Stake consensus mechanism they’ve adopted, neither network can be modified to serve the specific requirements DApp developers may have, such as instant settlement or off-chain storage. Dymension helps to address this challenge by allowing developers to spin off new blockchain platforms with custom features to support their applications.
