Hey! Why did you decide to create a project on the base of blockchain?
In essence, blockchain will allow for:
1) Data synchronisation across different services.
2) All transactions coming through the marketplaces and the GG Ecosystem will be pegged to the IDs. Hence we will create a high-quality buying behavior prediction tool, used by marketplaces to increase their sales.
3) Lower the commission fees from 7-15% to 0-0.1%.
4) Creation of a decentralised Jury consensus based on the user rating system.
