Ethereum signature aggregation

1. Many blockchain projects are developed on the basis of ethereum's open source technology. Ethereum is a common public chain technology, and the deployment of applications on Ethereum has high requirements for developers. Developers need to consider many technical details and business processing logic, as well as security vulnerabilities such as smart contract overflow
the trust union credit alliance chain is located in the financial public chain, which is oriented to the high-frequency financial application scenarios in the field of credit and assets. It does not use eth, EOS, Neo and other general public chains, but uses the account structure of star network, adopts the lightweight intelligent contract layer, and the whole technical architecture is molarized according to "high aggregation and low coupling", This enables the trust union credit alliance chain to adapt to the requirements of rapid development, rapid implementation and timely response of Internet financial procts.

2. At the top of Ethereum is DAPP. It exchanges with the smart contract layer through Web3. JS. All smart contracts run on EVM (Ethereum virtual machine) and use RPC calls. Below EVM and RPC are the four core contents of Ethereum, including: blockchain, consensus algorithm, mining and network layer. Except DAPP, all other parts are in the Ethereum client. The most popular Ethereum client is geth (go Ethereum)

3. GBK
Ethereum is an open source public blockchain platform with smart contract function, which provides decentralized virtual machine (Ethereum virtual machine) to process point-to-point contract through its special cryptocurrency Ethereum. The concept of Ethereum was first inspired by bitcoin by vitalik buterin, a programmer, between 2013 and 2014, and now it's 2.0. Ethereum 2.0 is also something that the whole coin circle is waiting for. In order to celebrate the birth of the genesis block of eth2.0 on December 1, chinacoin officially supports the exchange of eth2.0 verification nodes at 17:00 Hong Kong time on November 20, 2020. It will invest its own eth in the verification node mining and exchange qeth to obtain liquidity. It will participate in the mining as soon as the exchange is received. Now it will give back to the user's welfare. The top 1000 eth enjoy the over exchange of qeth according to the ratio of 1:1.02. Compared with eth2.0, qeth has too many advantages: liquidity is guaranteed, users do not need to bear the technical cost, the threshold of participation does not need 32 eth, as low as 0.1eth, nodes are maintained by the platform, and the revenue is distributed according to eth2.0< br /> < br /> < br /> 

4. Ethereum also uses blockchain technology, but it is more convenient to use than bitcoin's blockchain Turing, which is complete and open source. Anyone can create their own application on the basis of Ethereum

It does not belong to MLM

Ethereum is an open source public blockchain platform with smart contract function, which provides decentralized virtual machine (Ethereum virtual machine) to process point-to-point contract through its special cryptocurrency Ethereum

the concept of Ethereum was first proposed by vitalik buterin, a programmer, from 2013 to 2014, inspired by bitcoin, to the effect of "next generation cryptocurrency and decentralized application platform", and began to develop through crowdfunding in 2014. The market value of Ethernet currency is second only to bitcoin, and it is the second largest encrypted digital currency in the world

extended data

bitcoin has created the first decentralized cryptocurrency, and has fully tested the feasibility and security of blockchain technology in more than five years. In fact, bitcoin's blockchain is a set of distributed database. If a symbol bitcoin is added into it and a set of protocol is specified, the symbol can be transferred safely on the database without trusting a third party. The combination of these features perfectly constructs a currency transmission system bitcoin network

however, bitcoin is not perfect, and the scalability of the protocol is a deficiency. For example, there is only one symbol in the bitcoin Network - bitcoin, and users can't customize other symbols. These symbols can represent the company's stocks or debt certificates, which will lose some functions

In addition, a stack based scripting language is used in bitcoin protocol. Although this language has some flexibility to realize functions such as multi signature, it is not enough to build more advanced applications, such as decentralized exchanges. Ethereum is designed to solve the problem of insufficient scalability of bitcoin

6. Ethereum can be said to be a very successful currency in technology. In a short period of time, it has formed a trend of convergence. No matter in the technical level or in the market level, it has received global support, and the applications developed around it are emerging in an endless stream. At present, its price has been hovering at 3000 yuan for nearly half a month. I believe that with the progress of the bifurcation, its price is likely to exceed 4000 yuan by the end of the year. As the second largest market value of blockchain projects and bitcoin projects, its value is obviously likely to rise

Ethereum uses fog computing. The data processing and applications of fog computing are concentrated in the devices at the edge of the network, rather than almost all stored in the cloud, which is an extension concept of cloud computing, which is more in line with the spirit of decentralization of blockchain. If all the storage and operations still stay on the centralized server, then it will not be a real blockchain
recently, the hot "ethereal cat" on Ethereum network has led to the congestion of Ethereum network. The problem is that the TPS concurrency per second of Ethereum is too low. The emergence of ethereumfog with fog computing will break the embarrassing situation of Ethereum network congestion, and add powerful decentralized storage and additional computing power to the chain.

the concept of fog computing may be unfamiliar to many chain friends, but it is the most important aspect of ether fog to attract investors. In fact, I have heard about the concept of fog computing for a long time, and I have always thought that fog computing is the future development direction. When it comes to fog computing, we should start with cloud computing. In fact, the cloud computing we see now evolves from the cluster of independent servers, that is, from the original centralized independent servers to large server clusters, but in the final analysis, it is still a form of centralized computing. Compared with cloud computing, which is the evolution of centralized computing, fog computing is to share computing tasks with various computing power devices around us, and realize the evolution of decentralized and distributed computing, which coincides with the philosophy of blockchain itself.

8. Blockchain exchange
you mean platform trading. Domestic illegal, international and mostly deceptive, you find the well-known ones. There is a special introction to blockchain network. Remember to be legal, otherwise you can't withdraw cash and it's useless to make money.

9. At present, there are many digital currency wallets, some of which have good personal experience

light wallets are good for imtoken, geekwallet, kcash, Cobo, etc.

Hardware wallets are good for ledger, trezor, etc., which involve large amount of digital currency or hold for a long time. Generally, hardware wallets are recommended

big body introces these personal good light wallets
