DE-LIGHT HQ: Seoul, Korea

DE-LIGHT offers technical leadership in blockchain technologies, and it aims to support and scale the decentralized ecosystem by providing world-class protocols with rapidly deployable solutions.


1. Proposal introduction (What)

DE-LIGHT's engineers bring together core experiences as the former Chain Partners team responsible for node operations on EOS, Sovrin, Worbli, Orbs, and other blockchain projects. The team is composed of enterprise software engineers who formed one of the earliest Korea-based node operations/infrastructure-as-a-service companies for decentralized projects. Currently, DE-LIGHT is running node operations for Terra, a well known Korean stablecoin project.


2. Motivation of the proposal (Why)

DE-LIGHT recognizes ICON's early progress in the Korean blockchain ecosystem, and as a Korean company, we are the most closely aligned to the needs of its developers and community. 


3. Execution plan of the proposal (How)

We plan on launching 2 instances at the start and continuously scale to an optimal number based on performance and output. We plan on following the recommended server guidelines and the optimize as we better understand the protocol and unique features.


4. Expected timeline of the proposal (When)

Stage 0 (July-Aug): As soon as we can, begin node operations on the ICON testnet. Use this opportunity to test, validate, and optimize initial settings.

Stage 1 (July~): Launch node(s) on ICON mainnet; make continuous improvements.

Stage 2 (September~ ): Develop further tools that contribute to the ICON network and community.
