Chinese netizens have used the Ethereum blockchain to share a censored news story about faulty vaccines given to small babies.
In early July, 3-month-old children were immunized against diphtheria, whooping cough, and tetanus with inferior vaccines supplied by the China’s Changchun Changsheng bio-technology corporation. A government investigation revealed that the vaccine maker had sold over 250,000 substandard DPT vaccines.
The news about this incident fell under state censorship — the Chinese authorities have prohibited publication of material on ineffective vaccination theme in the media and social networks. As Ethereum is decentralized and hard to tamper with, Beijing monitors cannot intervene and push the network’s owners to take down the transaction.
It is not the first time Chinese users take advantage of the blockchain to bypass Internet censorship and express their complaints. In April, student activists shared via the Ethereum blockchain an open letter from a student of one of the Chinese colleges, who had accused his teachers of sexual assault and harassment. Currently, this letter is still available on the blockchain for all to look at, that is a rare exception for most dissent-themed material in China.
