Is multi signature decentralized

1.

blockchain and artificial intelligence are the next era

There is a good combination between the two

blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. Blockchain is an important concept of bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains a batch of information about bitcoin network transactions, Used to verify the validity of its information (anti-counterfeiting) and generate the next block

artificial intelligence, abbreviated as AI. It is a new technical science to research and develop the theory, method, technology and application system for simulating, extending and expanding human intelligence

Artificial intelligence is a branch of computer science, which attempts to understand the essence of intelligence and proce a new intelligent machine that can respond in a way similar to human intelligence. The research in this field includes robot, language recognition, image recognition, natural language processing and expert system. Since the birth of artificial intelligence, its theory and technology have become increasingly mature, and its application fields have also been expanding. It can be imagined that the scientific and technological procts brought by artificial intelligence in the future will be the "container" of human intelligence. Artificial intelligence can simulate the information process of human consciousness and thinking. Artificial intelligence is not human intelligence, but it can think like human and may surpass human intelligence

At present, blockchain technology can be divided into three versions

At present, in the first three versions, there are some problems, such as the lack of decentralization, low scalability, the mismatch between the incentive of the blocker and the best profit of the whole network, and the network always runs at the maximum capacity, such as bitcoin and Ethereum, which affect the efficiency

Velas combines the two to develop a public chain that can learn and improve itself

Velas enhances its consensus algorithm through artificial intelligence (AI) optimized neural network, and concts self-learning and self optimized public chain, aiming at improving the security, interoperability and high scalability of transfer process and intelligent contract. Velas adopts the dpos consensus enhanced by AI, which completely realizes decentralization without recing the security and transaction speed

technically, Velas has integrated functions and services such as cross chain payment, multi signature wallet supporting multi currency, anonymous transfer, etc. Its Ecosystem focuses on all application scenarios covering transaction and payment, such as exchanges, multi signature wallets, merchant platforms, etc. after AI is fully connected to the system, the transfer fee can be completely exempted

and complete decentralization through AI enhanced dpos (aidpos) & gt; AI chooses who to mortgage the token according to the needs of blockchain & gt; Velas only blocks when needed & lt; Between every 1 second and every 2 minutes & gt& gt; Scalability (up to 30000 TPS) & gt; Block procers are selected by artificial intuition< br />

2. A decentralized digital currency storage scheme is provided for users. The wallet key and the address and private key information of all kinds of currencies are stored in the user's local system. At the same time, the wallet provides a convenient key backup scheme - users only need to backup once and save it in a safe place. Even if the types of digital currency are added subsequently, all types of digital currency assets can be recovered with backup. In addition to allowing users to fully control the key of the wallet, the wallet also provides multi signature technical support and two-step authorization verification for digital asset management of different scales. Users can choose mobile phone verification code, fingerprint, living body and other verification methods ring transfer transactions to ensure the security of digital currency assets in an all-round way.

There must be radiation from virtual currency mining, including mobile phones and computers, not to mention mining

Mining is a process of consuming computing resources to process transactions, ensuring network security and keeping everyone's information synchronized in the network

it can be understood as the data center of bitcoin. The difference lies in its completely decentralized design. Miners operate all over the world, and no one can control the network

this process is called "mining" because it is similar to gold panning, because it is also a temporary mechanism for issuing new bitcoin

however, unlike gold panning, bitcoin mining provides rewards for services that ensure the safe operation of payment networks

after the last bitcoin issue, mining is still necessary

extended data:

bitcoin mining machine is a computer used to earn bitcoin. This kind of computer generally has professional mining chips, and mostly works in the way of display card, which consumes a lot of power

one of the ways to get bitcoin is that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server

the popular digital currencies in 2013 are bitcoin, Leyte coin, zeta coin, pennies (Internet), invisible gold bar, red coin, pole coin, barbecue coin and prime currency

At present, there are more than 100 kinds of digital currency in the world

bitcoin is a kind of virtual currency. Bitcoin mining system is the process of carrying out mathematical operation for bitcoin network through computer hardware. Miners who provide services can get a reward, because the network reward is calculated according to the tasks completed by miners, so the competition for mining is very fierce

bitcoin mining started with low-cost hardware such as CPU or GPU, but with the popularity of bitcoin, the mining process has changed greatly

nowadays, the mining activities are transferred to the field programmable gate array, and the hash speed can be achieved through optimization, which has very high mining efficiency

XTT (Xin time token), based on Ethereum erc20 platform, is a decentralized digital currency carrier based on blockchain as payment technology

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

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 ICO crowdfunding in 2014

background

bitcoin has created the first decentralized cryptocurrency, and has fully tested the feasibility and security of blockchain technology in more than five years

the blockchain of bitcoin is actually 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

5. I think it's convenient and safe to use kushenleng wallet, because the part storing digital currency can only communicate through two-dimensional code, it won't touch the network, and it's very safe to store.

6. This mechanism is the most concise design. It's understandable. It's very similar to the real world. Assuming that a and B can't trust each other, we introce a third party that a and B can trust together to act as a notary as an intermediary
in the blockchain, the third party can be a trusted central organization of both parties or a group of nodes. It not only collects data, but also confirms and verifies transactions
in the notary man-machine system, it can be realized through "single signature / multi signature notary mechanism" and "decentralized Transaction Protocol"
the advantages of this scheme are very simple and easy to understand. However, it should be noted that the security of the central node is the key bottleneck of the system stability in the single signature system; The security of multi signature is higher, but it needs two chains to support multi signature
in this mechanism, the most representative solution is ripple's cross chain value transmission technology protocol, interlegger protocal (ILP), which is not an account book and does not seek any consensus
on the contrary, it provides a top-level encryption hosting system called "connector", which, with the help of this intermediary, allows money to flow freely between the books
this agreement uses the password algorithm, the two ledger systems and the connector to create the fund custody. When all parties reach a consensus on the fund, the transaction can be completed
interleger portal removes the trust link needed by transaction participants, and the connector will not lose or steal funds, so this kind of transaction does not need the protection of legal contract and excessive audit, which greatly reces the transaction threshold. bitmom

7. The transaction data of AUV public chain is open and transparent. We choose the underlying technology of public chain to build a decentralized core privacy underlying accounting system of AUV public chain, which is a multi signature controlled access scheme based on public transaction records and sensitive data

8. With AUV public chain, all data are transparent, and there is no need to worry about false transactions and fake goods
