1. Enjin (enj)

in the near future, the game instry is the instry most likely to adopt blockchain on a large scale. Enjin coin is the cryptocurrency of virtual goods created by Enjin. Enjin is the "largest online gaming community platform" with more than 250000 gaming communities and 18.7 million registered gamers

Cardano (ADA)

compared with Ethereum, EOS and Tron, Cardano is the third generation of decentralized app (DAPP) and smart contract platform. Cardano's design philosophy has the following points:

scalability: with the growth of users, the transaction processing speed is not affected or even faster, such as P2P protocol

interoperability: in the future, there will be countless devices connected to each other, instead of only connecting and forwarding through routers. All kinds of devices can communicate directly through standard general protocol

Sustainability: like bitcoin, Cardano project will not be controlled and influenced by a certain company or organization, which is a safe, decentralized and sustainable development platform

With the popularity of sto (security token offers), Nash also plays an important role. Nash is a kind of registered security token. In the past, Nash participated in and led the development of many projects

Nash exchange is a decentralized exchange. If you hold nex token, you can calculate the dividend here

4. Basic attention token (BAT)

bat mainly solves the problem of advertising:

user information is abused: large companies such as Google and Facebook track and use user information and behavior, and sell without the knowledge of users

the effect of advertising is restrained: middlemen earn most of the fees, a large number of advertisements are blocked by users using software, and advertisements are fake

in the past six to 12 months, the number of publishers using the brand browser (Note: the brand browser supports bat token) has grown rapidly, and almost no blockchain ecosystem has grown so fast

5, chainlink (link)

chainlink mainly solves the problem that each blockchain has and the smart contract cannot obtain external data. In order to introce external data into the blockchain, the concept of Oracle is proposed in smart contract

companies including Google are supporting the development of chainlink. Here is a list of chainlink partners

one of the main problems of chainlink is similar to Ethereum. The development team has reserved 650 million link tokens, while only 350 million are in circulation at present

Ethereum (ETH)

Ethereum has long occupied the second place in the top 100 cryptocurrencies. Its ecology is so big that we can't call it altcoin now. To tell you the truth, I'm not optimistic about Ethereum in the long run, but it will flourish in the short run

The concept of bitcoin was founded by Nakamoto

On December 12, 2010, when bitcoin graally became a hot topic, he quietly left and disappeared from the Internet

As a descendant of samurai, Nakamoto was born in 1949 in Beppu, Japan. His mother, quanzi, was a Buddhist and brought him up in poverty

When his parents divorced in 1959, Nakamoto's mother remarried and immigrated to California with her three sons. Nakamoto and his stepfather don't get along well, but according to his younger brother Arthur, Nakamoto showed his talent in mathematics and science when he was very young, but also showed his "fickle and strange interest"

Nakamoto graated from Caltech, majoring in physics. Upon graation, he joined Hughes Aircraft and worked in defense and electronic communications. Later, Nakamoto worked for the U.S. military, and his experience was classified as a state secret. Now searching his files, his life is a blank

In 2008, in an e-mail group discussing information encryption on the Internet, he published an article outlining the basic framework of the bitcoin system. In 2009, he established an open source project for the system, officially announcing the birth of bitcoin. On December 12, 2010, when bitcoin graally became the climate, he quietly left and disappeared from the Internet

3. In the 1980s, a group of talented programmers explored this problem in the password mail group. In 1982, David Chaum proposed an untraceable cryptography network payment system. Eight years later, he extended this idea to cryptology anonymous cash system, namely ecash.
2 in 1998, Wei Dai's paper elaborated an anonymous and distributed e-cash system: B-money. At the same time, Nick Szabo invented bitgold and put forward the workload proof mechanism. Users solve mathematical problems competitively, and then publish the results in series with encryption algorithm to build a property rights authentication system. Hal Finney improved the mechanism as a "reusable workload proof"
3 on the basis of previous work, in 2008, the little-known "Nakamoto Tsung" published "bitcoin: a peer-to-peer cash payment system" in the cryptography mailing list of metzdowd.com. On January 3, 2009, bitcoin network was born, and Nakamoto himself released the first version of open source bitcoin client
since then, the monetary history of mankind has opened a new page.

historical background

bitcoin is one of the first currencies to realize the concept of "cryptocurrency". In 1998, Wei Dai first expounded the concept of "cryptocurrency" in cypherpunks mailing list. Based on the basic concept of money, which is used to pay for goods, services and debt or any form of records in a given country or economy, bitcoin is a new form of money. Its original design is to integrate the idea of not relying on the central authority, using the principle of cryptography to control the issuance and transaction of money
in 2009, Satoshi Nakamoto published the first bitcoin specification and its proof of concept in the cryptography mailing list. At the end of 2010, Nakamoto claimed that he had transferred to other affairs and left the project. The creator of bitcoin never revealed his true identity, but left his invention to the world. Today, the origin and motivation of the invention of bitcoin is still a mysterious story
since 2010, many developers have devoted themselves to this project, and the bitcoin community has grown rapidly. Between June and July 2011, bitcoin suddenly gained media attention, leading to large-scale buying. The resulting bubble led to the continued decline in the price of bitcoin in the second half of 2011. After that, the price of bitcoin graally rose to the height of 2011
in order to regulate, protect and promote the development of bitcoin, the bitcoin foundation was established on September 27, 2012. Nowadays, with the increasing number of bitcoin users, bitcoin economy is developing rapidly

technical features

any network like bitcoin has the following basic features:
bitcoin can be transferred between any node of the network
the transaction is irreversible
the use of block chain avoids the occurrence of double consumption
the transaction will spread out in a few seconds and pass validation in 10 to 60 minutes
transaction processing and currency issuance are carried out through mining
bitcoin can be received at any time whether it is online or not<

economic rules

the whole bitcoin network jointly implements the following rules:
the total amount of bitcoin issued is about 21 million
a bitcoin can be divided into 8 decimal places, with a total of about 21 × 1014 monetary units
transaction costs are very low and most of them are free

statistics

bitcoin network has been running continuously for more than 48 months. In the past year, bitcoin's security features have attracted attention and developed significantly. As of April 2013:
the longest block chain has more than 232000 blocks
one of the largest distributed computing networks in the world, with more than 65 trillion hashes per second
there are 50000 transactions every day, with a total amount of several million US dollars
the total value of bitcoin in circulation exceeds US $1.3 billion
there is only one major security incident in the protocol, which was resolved in August 2010

Usdt is a token launched by tether company, which is based on USD, a stable value currency. 1 usdt = 1 USD

users can use usdt to exchange 1:1 with USD at any time. The biggest feature is that it is equivalent to the same amount of US dollars, 1 usdt = 1 US dollar

usdt is not a new currency, and it has been traded online as early as 2015. However, e to the late introction of domestic exchanges, many investors do not know much about it

before okex and fire coin professional station launched usdt, bittrex, poloniex, hitbtc, coin an, Kraken, cryptopia, liqui and other platforms can trade usdt

after the currency transaction, many investors are more concerned about how to convert their tokens into legal coins. The emergence of usdt provides us with a channel to convert their tokens into legal coins

extended data

characteristics of TEDA currency

1. Stable currency:

tether converts cash into digital currency, anchoring or linking the prices of national currencies such as US dollar, euro and Japanese yen

2. 100% people support it:

in foreign exchange reserves, traditional currencies always support each currency at a price of 1:1. So $1 - $8366; It's always equal to one dollar

Transparency:

our foreign exchange reserves are published every day and subject to frequent professional audit. Everything in circulation always matches our reserves

4. Blockchain Technology:

tether platform is built on the basis of blockchain technology, making use of the security and transparency they provide

7. Tranche is a decentralized protocol for managing risk. The protocol is integrated with any interest accumulation token, such as compound's ctokens and AAVE's atokens, to create two new interest instruments, one with fixed rate tranche A and the other with variable rate trancheb. The protocol is currently integrated with compounds and charges Dai and eth. The accrued charges are exchanged into slice tokens through the uniswap pool. The slice holder can vote on protocol parameters and other governance issues, and can also use his slice or slice-lp token to reward.
