It may of course be utter rubbish, but let's say the Chinese government does block internet access to the blockchain itself.
As TOR seems very hit and miss there and VPNs are slowly being hunted to extinction what would be the options for a Chinese person who wanted to interact with it? Does the Blockstream satellite thing work?
1. Blockchain is a separate meshnet so you cannot block it.
2. TOR is suppose to be hit and miss to preserve your anonymity.
3. Blockstream satelite is just another mining farm. No relation to evasion against the Great Firewall fiasco.
