“The Great Firewall of China doesn’t prevent outbound packets from reaching the global internet but it definitely slows them down via inducing packet loss. On the global internet, there is a rate of 0.2% packet loss, while that rate is 6.9% behind the Great Firewall of China. The lost packets must be re-requested and re-sent, increasing latency from 81 milliseconds for the global internet to 218 milliseconds behind the Great Firewall of China.â€This is a big impact on the Bitcoin block propagation. It can take four seconds for blocks on the same side of the Firewall to propagate between nodes but it can take just over 17 seconds for blocks to propagate between nodes on the side. This results in a 450% slowdown. Chinese miners are now at a disadvantage since miners outside of the Firewall will be to broadcast a block much faster to the network and still receive a block reward. This goes through even if a miner inside the Firewall found a block earlier. What are your thoughts? Let us know what you think down below in the comments!
