Vitalik mentioned ETC twice recently and talked about the characteristics of ETC

On July 13 this year, Vitalik Buterin posted on the Ethereum Research Blog that in more than a year, the scalable data layer will become ETH 2.0 because its planned 10 MB/second data throughput is much higher than any existing blockchain . In the short term, we can start researching these technologies immediately by using existing blockchains (especially those with lower transaction fees per byte than ETH ) as data layers. BCH fully meets this standard, and another option is the ETC chain because it has a faster 14-second block time.
On July 16, Vitalik Buterin tweeted that ETC has about 5% of ETH hashrate and has even been attacked by 51%. Is it safe? I don't think adding flyclient and calldata to reduce fuel costs is a step backward on the ETC side. These changes are good for ETC, even if there is no cross-chain use case.
In fact, as early as May 2018, Vitalik Buterin tweeted his support for ETC, and many people began to discuss some past events about Ethereum . Many new investors actually did not know that Ethereum Classic (ETC) was the earliest Ethereum , and ETH was the product of a hard fork. Ethereum Classic (ETC) is a decentralized smart contract platform that retains the original Ethereum code rules and features, adheres to the concept of decentralization, and guarantees the consensus mechanism through blockchain .
Compared with ETH, ETC has the following characteristics:

1. ETC has low transaction fees. The transaction fee for each ETC transaction is about 0.01 USD, which is much lower than the transaction fee of 0.08 USD for each ETH transaction.
2. The block time of ETC is 14 seconds, and the actual transaction speed is faster than ETH.
3. After the Atlantis hard fork upgrade, ETC's system will be more compatible with ETH, greatly improving the performance of the ETC network, making the ETC network faster and safer, including optimized code for accelerated transmission. The upgrade also includes clearing the status of blank accounts and contracts to avoid the possibility of them causing security problems and congested networks. Since DApps run on ETC at lower gas fees, this will attract more DApps to be developed on ETC.
