Lightcoin expansion

They are:

bitcoin

the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's ideas, the open source software was designed and released, and the P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system

bitcoin cash

bitcoin cash is a new version of bitcoin with different configurations launched by a small number of bitcoin developers

extended data:

virtual currency refers to non real currency. Well known virtual currency, such as network company's network currency, Tencent company's Q currency, Q point, Shanda company's voucher, Sina's Micro currency (used for micro games, Sina reading, etc.), chivalrous Yuanbao (used for chivalrous road game), silver pattern (used for bixue Qingtian game)

the popular digital currencies in 2013 are bitcoin, Leyte coin, infinite coin, quark coin, zeta coin, BBQ coin, pennies (Internet), invisible gold bar, red coin and prime currency. At present, hundreds of digital currencies are issued all over the world. Popular in the circle & quot; The legend of "bitcoin, Wright silver, infinite copper, pennies aluminum"

Bitcoin, English name bitcoin, is a digital currency based on blockchain technology, which is composed of a series of computer-generated complex codes. Like RMB's ￥ and US dollar's $, bitcoin has its own symbol, the "B" in the figure below

The inventor of

bitcoin is Nakamoto. Satoshi Nakamoto is the creator of bitcoin protocol and its related software bitcoin QT. In 2008, he published a paper called "bitcoin: a peer-to-peer electronic cash system", describing an electronic currency and its algorithm that he called "bitcoin"

In 2009, he released the first bitcoin software and officially launched the bitcoin financial system

In 2010, he graally faded out and handed over the project to other members of the bitcoin community

Nakamoto is believed to hold about one million bitcoins. If the price of each bitcoin was $2W, it was worth $20 billion at one time. So far, his true identity is still unknown to the outside world, that is to say, no one knows who Nakamoto is

bitcoin appeared after the global financial crisis in 2008. In fact, before that, many people have tried electronic currency, digital currency and virtual currency, but they have not succeeded. There are not only technical reasons, but also social environment and economic background reasons. To some extent, it was the 2008 financial crisis that gave birth to bitcoin

3. How to operate the isolation witness? In fact, it's not so simple ~
isolation witness is a method of blockchain expansion, which has been successfully implemented on lightcoin and bitcoin
at present, each block in the blockchain not only records the specific information of each transfer transaction, that is, at which time point the account receives or transfers out how many bitcoins, but also contains the digital signature of each transaction, which is used to verify the legitimacy of the transaction. The miner needs to verify each transaction one by one with digital signature when packing the block. After confirming that there is no problem, the transaction will be recorded in the block
however, for ordinary users, they only care about the number of assets in each account, and do not need to verify each transaction one by one. Isolation witness is to take out the digital signature information in the block, so that each block can carry more transactions, so as to achieve the purpose of expansion.

4. Friends who are new to the currency circle are dazzled to see all kinds of digital currencies. What are the origins and characteristics of these cryptocurrencies? Here is a brief introction to some mainstream cryptocurrencies< Bitcoin is the earliest cryptocurrency. In 2008, an Internet geek named Nakamoto Tsung published a paper called bitcoin: a peer-to-peer e-cash system. In 2009, the first creation block was g up by Nakamoto Tsung and has been developing ever since. The original block size of bitcoin was only 1m, and the congestion problem was getting more and more serious. As a result, the block expansion was put on the agenda. The core development group advocated the use of isolation witness and lightning network to realize the expansion, while the big block group advocated the direct expansion of the block. At last, on August 1, 2017, bitcoin cash (BCH) forked from bitcoin (BTC) and expanded its capacity by expanding the block. After this split, bitgold, bitdiamond, super bitcoin, bitgod and many other split coins have sprung up. Later, BCH itself encountered a bifurcation. The Australian CSW, who calls himself Nakamoto Tsung, has to continue to expand the block and lock the underlying protocol of bitcoin. He claims to make a bitcoin that meets Nakamoto Tsung's vision. This time, the bifurcation coin is called BSV

apart from BCH and BSV, most of the other bifurcated currencies have declined. BTC, BCH and BSV represent the exploration of three different directions respectively. BTC is the most conservative and cautious, BSV is the most radical, and BCH is relatively mild and graal. At present, BTC enjoys the name of bitcoin in fact and has the largest market value< br />
< At the end of 2013, vitalik buterin (V God), a gifted programmer born in 1994, published a white paper on Ethereum, proposing the idea of adding various smart contracts to cryptocurrency, which can be used in social networking, trading, games and other fields. The market value of Ethereum has soared all the way, and it will soon be second only to bitcoin, Ethereum with smart contracts is also known as blockchain 2.0

in 2016, Ethereum encountered a serious hacker coin theft incident (DAO), and God V decided to delete the coin theft record by using rollback method. However, some people who insisted that the blockchain should not be tampered with opposed rollback, so Ethereum also split. Unlike bitcoin, the original Ethereum chain has become a minority, known as the Ethereum classic (etc), and the new chain that has been rolled back has become a majority, the de facto Ethereum (ETH)

stable currency system

stable currency is generally anchored legal currency, which can be used to exchange legal currency 1:1 to the issuer. The currency value is relatively stable, but sometimes there will be a small amount of premium in transactions, which is widely used in cryptocurrency transactions. Now the most common stable currency is the usdt issued by tether company, 1 usdt = 1 dollar. Stable currency is generally issued on other cryptocurrency networks, such as bitcoin Omni protocol, Ethereum erc20 protocol, etc< br />


in anonymous currency

on bitcoin, every transaction is clear and searchable, although we don't know who the person behind the address is. Some people think that the privacy of bitcoin is not enough, so some anonymous coins, such as XmR, dash and zcash, which can cover up user information, have emerged. Monroe coin uses ring signature technology, dasey coin adopts mixed coin technology, and big zero coin uses zero knowledge proof, which can play an anonymous effect in different degrees

platform currency system

some digital currency trading platforms often release their own platform currency, and there are certain discounts for trading with platform currency, such as okb of okex, HT of fire currency, BNB of coin security, etc<

some other mainstream currencies

lightcoin (LTC) has copied the code of bitcoin, replaced the consensus algorithm, and shortened the block out time. When bitcoin wants to upgrade, it often does experiments on bitcoin first. Lightcoin is known as "bitcoin, lightsilver"

XRP is currently the third largest currency in market value. It is an Internet transaction protocol, allowing users to transfer money around the world quickly and cheaply

grapefruit coin (EOS), known as blockchain 3.0 and Ethereum upgrade, attempts to introce more functions and application expansion on it

"bitkangaroo" is the first digital currency financial service platform in the world that allocates theoretical revenue from its own mines and machines without power failure. The platform is mainly based on cloud computing procts, and the theoretical revenue is allocated by "1tash" of Wanyou computing power's professional mine, a strategic partner, on a regular basis every day, integrating high-yield, security, liquidity, transparency and professionalism

High Yield: the platform aims at "increasing users' assets", and customers can choose a variety of derivatives to prevent systemic risks

Security: the team stores the standby digital assets in the cold multi signature wallet, and in case of any accident, the reserve fund will be used to distribute revenue to customers

Liquidity: the platform allocates income every day, and can withdraw as soon as it reaches the minimum currency withdrawal standard

transparency: mine data and mine logs are open and transparent, and users can monitor the actual computing power of the mine at any time through the data center monitoring system

Professional: the mine is operated and managed by professional personnel who have been engaged in deep mining for many years. Each unit is isolated by professional network interruption to prevent virus invasion. Multiple standby networks are used in the computer room to eliminate non systematic risks in an all-round way

5. The increase of blockchain network information is bound to need expansion, but it is not limited to a BTC public chain. No matter which public chain develops to a certain stage, it needs expansion technical support network. Therefore, it can be said that expansion is a necessary link for the implementation of blockchain scheme
the expansion of blockchain is the general trend, but there are differences in the specific operation. According to the different levels of blockchain architecture, the instry has proposed a number of expansion solutions: first, optimize the data transmission protocol for the underlying data layer of blockchain, do not change the upper structure of blockchain, and improve the scalability, such as bloxroute, the 0-layer expansion scheme of blockchain; The second is to change the data structure and consensus algorithm to improve the scalability of the basic protocol of blockchain, such as DAG (directed acyclic graph), fragmentation, dpos algorithm, etc; Third, aiming at the application level, such as side chain, sub chain, state channel lightning network and so on, part of the on chain transactions are transferred to the off chain execution to rece the on chain processing pressure and improve the overall efficiency.

Jybusd: the lucky dollar is a kind of digital currency, but it has been proved to be a kind of digital currency fraud

digital currency investment needs to pay attention to the following matters:

1. Regular security platform

8. Looking back on nearly 30 years of my life, I didn't do anything to turn the tide. The only time I did it was in grade three or four of primary school. I happily packed my schoolbag on the last day of summer vacation to prepare for the start of the new semester the next day. At that time, I was used to doing a good job. I checked all my summer homework to see if there were any mistakes, but I really checked the problems, There was a Book of Tian Zige's calligraphy practice that I didn't write. In an instant, my blood rushed to my head and I shivered all over. But I immediately started to make up my homework. It took three hours to make up one book. I took a temperature from the normal temperature to a high fever of 39 ° Many, but fortunately the next day can be at ease to go to school. Does that count?! ha-ha
