ETH, if most people agree to modify the chain, that is, variability, then both blockchain records and contracts can be modified.
Blockchain records and contracts cannot be modified, that is, they cannot be tampered with.
The following are the advantages and disadvantages of the two methods.
The advantage of variability is that people can make correct decisions in time, so it is more practical to modify specifications than to find loopholes.
No matter how clever people were at that time, it was impossible not to make mistakes. Therefore, when there are problems in this scheme, it is best to find and solve the loopholes through the existing legal framework.
About the differences in development.
ETH, whether deliberately arranged or from the day of its birth, the core decision of blockchain was made by the Ethereum Foundation with the participation of the community, and most of them were made by it.
The decision of blockchain is mainly decided by three loosely cooperative teams involved in the community.
In any case, anyone can make suggestions for improvement of the two blockchains, which is the benefit of open source and is also very common. You will find that the developers of these two chains communicate with each other through Github and Reddit. I hope to increase the frequency of communication to achieve the same goal.
About compatibility
At present, these two blockchains are compatible with each other, and contracts or applications written by ETH can be applied on ETC, and vice versa.
ETH, focusing on eWASM, is committed to providing a platform for more and more developers, while contract security issues are secondary, such as Viper.
ETC focuses on allowing developers to create more secure contracts, such as Viper and IOHK research, at the expense of consuming the number of potential developers.
Obviously, these two chains are acceptable to each other, whether they have the same desire or not. In my opinion, the number of developers is not necessarily related to the quality of products.
About transaction speed
ETH, with an average of 25 seconds, will be shortened after upgrading.
ETC, average 14 seconds, maintained at 10- 14 seconds after upgrading, according to ECIP-10/0 and ECIP- 1036 protocols.
On block capacity
ETH, with the daily trading volume of ETH gradually reaching 5 million, the block capacity tends to be saturated, similar to the recent transaction cost of Bitcoin. This problem can be solved by expanding the block and increasing the default fuel limit.
Wait? At present, there is still a lot of room for block production capacity. As more and more people accept ETC, the capacity of block will increase, just like ETH.
About the community
ETH, mainly discussed on Reddit.
Wait, mainly discuss the relaxation degree.
About monetary policy
Federal Institute of Technology, the planned supply has grown steadily, resulting in an average inflation rate of 3% in the life cycle of the blockchain Federal Institute of Technology.
ETC, before 2025, inflation will reach 3%, total supply will reach 200 million ETC, and then deflation will occur.
On the regional distribution of transaction volume
ETH, China 20%, South Korea 25%, the United States 25%.
ETC, accounting for 50% in China, 25% in South Korea and 0/0% in the United States.
About securities
At present, investors do not have the option to trade securities. Recently, an ETF of ETH, a trading open index fund, was denied by the regulatory authorities.
ETC owns ETC Trading Trust Fund, which allows investors to own ETC without owning the asset itself.
