Iotoken and Ethereum
just like bitcoin, Ethereum is neither controlled nor owned by anyone - it is an open source project created by many people around the world. Different from bitcoin protocol, Ethereum's design is very flexible and adaptable. It is very easy to create new applications on the Ethereum platform. With the release of homestead, anyone can use the applications on this platform safely
Ethereum is a programmable blockchain. It does not give users a series of preset operations, but allows users to create complex operations according to their own wishes. In this way, it can be used as a platform for many types of decentralized blockchain applications
in a narrow sense, Ethereum refers to a series of protocols that define a decentralized application platform. The core of Ethereum is Ethereum virtual machine (EVM), which can encode any complex algorithm. In computer science terminology, Ethereum is "Turing complete.". Developers can use the existing JavaScript and python as the model of other friendly programming languages to create applications running on the Ethereum simulator.

about the variability of blockchain
-
eth, if most people agree to modify the chain, that is, variability, then they can modify the blockchain records and contracts
-
etc, blockchain records and contracts can't be modified, that is, they can't be tampered with
-
here are the advantages and disadvantages of the two methods
The advantage of -
variability is that people can make timely changes to make the right decisions. Therefore, modifying the specification is more practical than finding loopholes
-
non modifiability means that no matter how smart people are at that time, it is impossible not to make mistakes. Therefore, when problems arise in this scheme, it is best to find and solve the loopholes through the existing legal framework
-
differences in development
-
eth, whether it is intentionally arranged or since its birth, the core decisions of blockchain are made by Ethereum foundation with the participation of the community and most of them are developed by it
-
etc, the decision-making of blockchain is mainly decided by the feedback of three loose, collaborative teams with community participation
-
in any case, anyone can put forward improvement suggestions for the two kinds of blockchains. This is the benefit of open source, and it is also very common. You will find that developers of the two chains communicate with each other through GitHub and reddit. I hope to improve the frequency of communication in order to achieve the common goal
-
about compatibility
-
at present, the two kinds of blockchains are compatible with each other. 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 the issue of contract security is secondary, such as viper
-
etc focuses on making developers create more secure contracts, such as viper, iohk research, at the cost of consuming the number of potential developers
-
it's obvious that both chains can accept each other, regardless of whether their wishes are the same or not. My view is that the number of developers is not necessarily related to the quality of the proct
-
about the transaction speed
-
eth, the average is 25 seconds, which will be shortened after upgrading
-
etc, with an average time of 14 seconds, maintained at 10-14 seconds after upgrade, according to ecip-1010 and ecip-1036 protocols
-
about the block capacity
-
eth, with the daily trading volume of eth graally reaching 5 million, the block capacity is graally saturated. This situation is similar to the recent transaction cost of bitcoin. This problem can be solved by expanding the block capacity by increasing the default fuel limit
ETC， At present, there is still a lot of room for block capacity. As more and more people accept etc, the block capacity will also increase, just like eth
-
about community
-
eth, mainly discuss on reddit
-
etc, mainly discuss on slack
-
about monetary policy
-
eth, the planned supply is growing steadily, resulting in an average inflation of 3% in eth blockchain in its life cycle
-
etc, before 2025, inflation will reach 3%, and then the total supply will reach 200 million etc, and then there will be deflation
As for the regional distribution of trading volume, China accounts for 20%, South Korea 25% and the United States 25% In etc, China accounts for 50%, South Korea 25% and the United States 10% About securities, at present, investors do not have the option to trade securities. Recently, one of eth's ETFs, trading open-end index funds, was denied by the regulators -
etc owns etc trading trust, which allows investors to own etc instead of the asset itself
Ethereum is not only a database, it also allows you to run programs in the trusted environment of the blockchain. Ethereum has built a virtual machine named EVM (Ethereum virtual machine) on the blockchain. EVM allows code to be verified and executed on the blockchain, providing guarantee for code to run in the same way on everyone's machine. These codes are included in the smart contract. In addition to tracking the account balance, Ethereum uses the same method to save the EVM status on the blockchain. All nodes process the smart contract to verify the integrity of the contract itself and its output.
DAPP can run on a centralized server that can interact with Ethereum nodes, or on any Ethereum node. Different from ordinary websites, DAPP can't run on ordinary servers. They need to submit transactions to the blockchain and read important data from the blockchain instead of the centralized database.
