Hi @imrane I can see where you're coming from but I would say this:

• I see decentralization as this holy grail of crypto but in practice crypto currencies are pretty centralized either because they rely on POW to secure their network (ex: Bitcoin mining is very centralized) or because they rely on a dev team who is in charge of their entire development;
• as for Coco, they are just a framework on top of a ledger which is itself "decentralized";
• the word decentralized gets thrown around a lot these days but I don't think it benefits every project, the key factor imo is privacy, if we can achieve a (albeit quite centralized) scaling solution while maintaining the privacy of the data in the network (what Coco offers basically) then the spirit of "decentralization will live on.
