Efficient Blockchain Fork claimed by Ethereum Classic

So-called "difficulty bomb" has been obviated by Ethereum classic: the upgrade took place at block 5,900,000, according to network data and project developers

Created to increase the difficulty of mining its blockchain through the time, the basic code was a feature of the original ethereum codebase (which later was divided into ethereum classic and ethereum) in 2016. Though it is hard to account for exact percentages in terms of how many nodes renewed their software, developers of the project declared that mainly exchange nodes and mining pools reported about updating their software long before the fork.

There were no features of any fails or bugs in the hours directly after the fork. The upgrade is awaited to reduce the amount of time it takes to create a block. Therefore, the upgrade states both technical and ideological difference between the ethereum classic and ethereum blockchains.

Because the ethereum community stays attached to passing to a proof-of-stake consensus system, the ethereum classic supporters have chosen to go on using proof-of-work, as its members maintain that, of the different methods to achieve consensus over block validation, it resists centralization best.

Especifically, advocates contend that proof-of-work systems demand their validators (miners) to continuously invest in hardware and  consequently in the blockchain. Deliberation on the fork began as early as 2016, and because of the broad  discussions, the upgrade was not expected to be complicated or controversial.

Great Chinese Firewall to Block ETH Explorer

Looks like it's the first time that a blockchain observer (etherscan. io in this case) has become a target for Internet censorship in China

The Great Chinese Firewall, used by the authorities to regulate access to foreign sites, blocked etherscan.io, one of the most popular services for viewing the statistics of the Ethereum network.

According to CoinDesk, as of early December, the portal is not accessible from IP addresses in mainland China. According to the service greatfire.org, blocking has been carried out at least since October 30.

Presumably this is the first time that a blockchain observer has become a target for Internet censorship in China.

This is another instance of friction between the decentralized and immutable technology of blockchain and the tightly controlled, centralized government of China. We should expect additional problems like these in the future as blockchain is integrated further into the Chinese economy and daily life.

In his opinion, we should expect similar problems in the future, since the blockchain is increasingly being integrated into the Chinese economy.

It is not known exactly what caused etherscan.io to become blocked.

Last year, it was reported that users encoded censored articles in an Ethereum transaction and shared the hashes of these transactions in the WeChat messenger using etherscan.io.

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.

The founder of etherscan.io, Matthew Tan, confirmed that the site in China has been blocked "for the past three months." He could not name the exact date and reason for what happened.
