**Affirmed position.** Key Technologies of a Service Platform Based on Blockchain Technology presents the following source proposition: This article aims to study the key technology of a service platform based on blockchain technology. This proposition is pertinent to Kaal's source-bound claim that The more digital assets are held by their owners in self-custody, the less likely intermediation by custody service providers becomes, so self-custody is the key driver of decentralization in emerging blockchain networks. The proposed response is an extension: the relationship should remain limited to the retrieved source proposition and the mapped Kaal claim unless fuller source review supports a broader conclusion.
