China's Great Firewall Blocked Ethereum Blockchain Explorer Etherscan

Francisco Memoria

China’s Great Firewall, a tool used by the Chinese government to block some websites within the country, has blocked the most popular Ethereum blockchain explorer Etherscan.

According to data from the non-profit organization Greatfire, which monitors a database of websites backed from IP addresses in China, the Ethereum blockchain explorer wasn’t blocked as of August 18 of this year, but is now “100% blocked.” This means that form within China, it’s only possible to access it using a virtual private network (VPN).

The block was first spotted by CoinDesk, which noted this is the first known case of a blockchain explorer being blocked by an internet firewall. Websites blocked in China include Reddit, Twitter, Google, and Facebook.

It’s believed the website was blocked because some within China were using the Ethereum blockchain to share content that is censored by China’s firewall. By encoding censored articles regarding a pharmaceutical scandal in China and the #MeToo movement on ETH transactions and then sharing these transactions using Etherscan, users managed to bypass censorship.

Matthew Graham CEO of blockchain investment firm Sino Global Capital, was quoted as saying:

Some have used this feature to post sensitive messages without the need to worry about the message being blocked or removed, or their identity being exposed. Anyone with a blockchain explorer like Etherscan can view these messages, so it is not surprising that this website has come in the crosshairs of internet censors

Etherscan’s founder and CEO Matthew Tan revealed the firm did notice the ban “within the last 3 months,” but didn’t know what prompted the ban. Some are now using a substitute website,, to bypass the ban. Other Ethereum blockchain explorers are notably accessible from within mainland China.

Max Keiser: Bitcoin Dominates Altcoins in Cryptocurrency Debate

  • Keiser Report host Max Keiser claims that bitcoin continues to dominate altcoins and provide more investor security.
  • Keiser predicted bitcoin's market dominance and hash rate to reach 99 percent within the next five years. 

Max Keiser, host of the Keiser Report, claims that bitcoin has no cryptocurrency rivals and that most altcoins fail to live up to the standard set by BTC. 

Speaking in an appearance on London Real, Keiser dismissed the possibility of a new crypto-asset emerging and eating into bitcoin’s market dominance. 

He said, 

There’s no coin out there that can do what Bitcoin doesn’t do already or will be able to do shortly. What you’re buying with Bitcoin is security.

Keiser continued, arguing that hard forks of bitcoin such as bitcoin cash and SV lack security compared to the original BTC.

The avid bitcoin supporter also referred to several altcoins as being “pure exit scams,” intentionally designed to manipulate investors. 

He explained, 

They have huge ‘pre-mines’ that the founders are selling or dumping and making a lot of money. A lot of people are losing money, and they have no use case. So like a Ripple or an Ether, even, is an exit scam. It’s to be avoided. Those are the top coins.

Keiser predicted that bitcoin’s market share and hash power, sitting at 65% and 85% respectively, will continue to rise relative to the market. He claimed that within five years bitcoin will account for 99% of all cryptocurrency hashing power and market capitalization.
