OP, it could be nice if you add a link to english version of the article. Because this one is leading to Japanese (or some other asian dialect) version and switching to english is removing you from the article.
Also this thread should belong to Altcoin Discussion board instead of this one.
So how will they achieve this without breaking decentralization or the blockchain?. My guesses are,they will desecrate the blockchain, centralize it, use censorship, remove immutablity, introduce trust/permission, become a CEO of blockchain lol (heard there is already a CEO of tron)
That's the way everything could work if it happened in China. But Japan is well-known as a crypto friendly country with crypto friendly laws and big amount of users so nothing tells us that someone is going to centralize TRON.
I also think that there is nothing wrong with that. Japan is one of the first states to legalize cryptocurrency in April 2017. Perhaps Tron wants to establish itself in the cryptocurrency market of Japan. In any case, the popularity of this coin should not suffer from such a step. Tron is now the other way around, well developed.
