Tangle blockchain

1. Digiccy is the digital currency. If you look at the ranking of digital currencies in the world in 2018, you can know it as follows:
1. bitcoin / BTC
founder: Nakamoto Tsung
originally proposed by Nakamoto Tsung in 2009, according to the idea of Nakamoto Tsung, we designed and released open source software and built P2P network on it. Point to point transmission means a decentralized payment system, which once had no more than 10.5 million in four years, and then the total number will be permanently limited to 21 million
2. Ethereum / eth

founder: Geoffrey Welk
it is not only a virtual currency, but also a platform and a programming language, enabling developers to build and release the next generation of distributed applications. Ethereum can be used to program, distribute, guarantee and trade anything: voting, domain names, financial exchanges, crowdfunding, corporate governance, contracts and most agreements, intellectual property, and smart assets that benefit from hardware integration< 3. Ripple / XRP is the base currency of ripple network. It can circulate in the entire ripple network, with a total amount of 100 billion, and graally decreases with the increase of transactions. The operating company of ripple is ripple labs (formerly known as opencoin)
4. Bitcoin cash (BCC) / BCH

founder: Roger ver
bitcoin forked coin. Viabtc, a mining giant owned by bitcoin mainland, has prepared a set of hard forked system based on the original chain of bitcoin
5. EOS

founder: Daniel Larimer
BM (Daniel Larimer), a blockchain architecture platform similar to the operating system, is developed to realize the performance expansion of distributed applications
6. Litteoin / LTC is an internet currency based on peer-to-peer technology and an open source software project under MIT / X11 license. It can help users make instant payments to anyone in the world
7. Stellar

founder: Jed McCaleb
the digital currency project initiated by Jed McCaleb, the former founder of ripple, is used to build a decentralized gateway between digital currency and fiat money. It will be provided to users in the form of free distribution, and its supply online is 100 billion, of which 95% of the amount of star coin is used for free distribution
8. Cardano

founder: Charles hoskinson
the end result of ADA cryptocurrency, which can be used to send and receive digital funds. This kind of digital cash represents the future currency, through the use of encryption technology, can be fast, direct transfer, to ensure its security
9. Tether

founder: Craig sellers
tether USD, a token launched by tether company, is based on the stable value currency USD. Users can query funds on tether platform to ensure transparency. Each TEDA coin is symbolically associated with government supported legal tender< Iota
10, iota

founder: David sonstebo
a crowdfunding project started in 2014, which is a revolutionary transaction settlement and data transfer layer specially designed for the Internet of things. It's based on a new type of distributed ledger, tangle, which is like a blockchain, but it uses a network structure instead of a chain structure, which makes it more scalable and stable.

When driving on high speed, we all know that it is very convenient to install an etc, because it can pass through the toll intersection quickly without parking. This also saves a lot of time for the majority of car owners, because sometimes if we stop and then go to pay, it may delay some valuable time{ RRRRR}

in fact, sometimes I think this kind of equipment is very convenient, but the conditions in various aspects may not be very mature now, so sometimes it will lead to a wrong dection. In life, our car owners may feel very troublesome. We should protect our own interests. Even if your money is dected, you should respond in time. Or upgrade the system

3. INTERVALUE Internet value fully absorbs the advantages of existing blockchain 1.0, blockchain 2.0 and blockchain 3.0 projects, solves their outstanding problems and technical defects, and builds a more prosperous application ecology. INTERVALUE innovatively designs the data mapping mechanism on and off the chain, a new enhanced data structure based on DAG and hashnet, a double-layer consensus mechanism based on hashnet consensus and ba-vrf consensus, a high-level Turing complete smart contract with external trigger conditions, a quantum attack resistant cryptographic algorithm based on keccack512 hash algorithm and ntrdsign signature algorithm, and a quantum attack resistant cryptographic algorithm Based on ring signature and zero knowledge proof, transaction anonymity protection mechanism, multi chain fusion mechanism based on cross chain adapter and external subnet, it has the functional features of blockchain 4.0, such as fast transaction confirmation, resistance to quantum attack, node anonymous communication, transaction anonymity protection, advanced intelligent contract, data link, etc., and supports the third-party asset issuance, transaction anonymity protection, advanced intelligent contract and data link by adopting fair distribution mechanism Cross chain communication, multi chain fusion and other functions< br />

4. Miota, eota, is a crowdfunding project in 2014. Its purpose is to use DAG (directed acyclic graph, which is called tangle in iota) instead of blockchain to realize distributed and irreversible (guaranteed by cryptography) information transmission. On this basis, it integrates encryption currency function to serve the Internet of things
it is a revolutionary new transaction settlement and data transfer layer designed for the Internet of things. It's based on a new type of distributed ledger, tangle. Tangle is the name of ledger structure. Tangle is like blockchain, but it uses network structure instead of chain structure, which makes it more extensible and stable
and it has no mining, no blocks, no transaction costs. Its application field is located in the Internet of things, as the technology of data integrity and instrial equipment. In addition, we need to pay on demand for micro payment and machine communication, such as sensor technology, smart city, adaptive system and so on
the goal of iota is to become a cryptocurrency for the Internet of things. As machine to machine connections grow, iota wants to be the currency that drives its transactions. When the project was launched in 2015, 1300 bitcoins were raised through "first coin", some of which were donated to the foundation. Iota is now the 11th largest cryptocurrency in circulation, worth $5 billion.
