You can use over TOR that would avoid the block. If TOR was not blocked!
Tor is pretty hard to block. Even China is having a hard time doing it and they have thousands of people employed on trying to block all of the bridges. It will be even harder with IPv6 probably.
There are also Blockstream satellites by now that cover almost the whole world. Only Asia left, should be finished by the end of the year. These satellites freely broadcast the blockchain and you can by all of the equipment for like 100$.
The satellite is amazing. And the 100$ is kind for every one.
But I think not only needs downloading the signals from SAT, but also need uploading the data to the SAT. Does the price including the up-way equipment?
As I understand, they don't do up. You couldn't upload even if you wanted to, they have their own transmitters for that.
I assume that the idea here was that it is simpler to bypass restrictions to upload then to download. If you are to post a transaction, you can just go to one of many sites and post the raw hex transaction and they will broadcast it to the network for you.
Also with the Lightning Network there will be off chain transactions for which you won't need to upload transactions to the blockchain, but will still need to download the blockchain for security reasons (to know if the other party closed a channel).
