i don't know if it is because of the translation from Chinese to English or is it just me but this statement doesn't even make sense to me.
first of all blockchain is not a software, it is just a ledger, or a chain of blocks and nothing about it is centralized.
even if they meant the technology and development of it, it is still not centralized.
and making anything centralized about cryptocurrencies is practically killing them. that is why altcoins that went that way are never going to succeed.
My feeling is that a lot of these "officials" have no idea what they are talking about and just sprinkle the conversation with buzzwords like "blockchain" to try to look like they are cutting edge, to impress people with even less knowledge than themselves.
It is impossible to have a blockchain without a coin, and it's impossible to have a centralised blockchain, yet you keep seeing both businesses and govts talking about it like it is possible.
