Do increasingly larger blocks create better security for the BCH network due to larger chinese miners being unable to keep up with data throughput past the china firewall, and thus eventually excluding them from being a potential hashpower threat to BCH?

Question

I would also think that over time the firewall may get faster too? What are everyone's thoughts on this?

Probably not. If the Chinese government decided that control of it was a priority they'd just put in a firewall exception or some such. It's only while Chinese mining isn't a threat that the firewall would be an impediment to their miners.

By "threat" I thought OP was more talking about the Chinese government wielding control over a blockchain by using hashpower to white-list or black-list transactions. I'm saying that if the CCP ever decided they wanted to wield that control and the firewall ever became an impediment to that control they'd just find a way for transactions and blocks to pass through without slowdown.

Sudden fluctuations of hashpower such as what crippled BTC (even more) are relatively straightforward for BCH to adapt to.

Whoops sorry. I changed my mind about my comment before I saw your reply but thanks for clarifying.

The chinese government are another potential threat for sure. especially if they decide (if they haven't already who really knows) they want to taker ownership of the miners and start running it themselves.

I heard that it's not the firewall, but chinese telecom duopoly and how they overbook the lines, causing many packet losses. Packet loss in TCP is the main problem, but there are other protocols to use. https://www.reddit.com/r/btc/comments/lmnd96/bch_vs_btc_lets_be_honest_both_coins_are_crippled/go1zip7/?context=3

Interesting. thanks for that.

Yes, smaller blocksize makes it easier to censor transactions and tends to be more centralized than blockchain with larger blocksize.

You can't exclude majority of hashpower, if they can not keep with data throughput, they will just mine empty blocks, headers first mining.

If they can't download the full blocks fast enough to mine anything but an empty block, it doesn't sound like the 'majority of hashpower' can win any hashwar other than a costly war to temporarily DoS the chain by choking it with empty blocks.

Nobody is talking about any war.

Semantics. The only way for Chinese govt to leverage Chinese 'majority of hashpower' (which you mentioned) and mount a 'hashpower threat' (as OP suggested) is through a conflict of aims where the greatest hash wins: otherwise that 'majority' becomes politically irrelevant.
