Current solutions for designing and building decentralized blockchain applications lack interoperability. Consequently, blockchains and existing technologies do not integrate well into a unified framework. This integration is necessary to work around some of the blockchains constraints, such as scalability of transactions and ergonomics. Indeed, blockchains are not suitable for huge data storage, but there are distributed data storage solutions that can be used in a decentralized blockchain application. Regarding ergonomics, the use of blockchain technology should be in the background and transparent for users that may not know how to set up and secure a blockchain-based application. We propose an architecture aiming to easily link existing decentralized technologies and blockchains. We then discuss the impact of this architecture for the video game industry. As a result, we propose an original data representation of blockchain gaming assets in order to improve data exchanges in this industry.
