Is lightcoin POW algorithm
Litecoin (LTC, currency symbol: 321;) It is a kind of network currency based on "peer-to-peer" technology. It is also an open source software project under MIT / X11 license. It can help users make instant payments to anyone in the world< better use of digital currency trading platform coin exchange
data expansion:
lightcoin is inspired by bitcoin (BTC), and has the same implementation principle in technology. The creation and transfer of lightcoin is based on an open source encryption protocol, and is not managed by any central organization. Lightcoin aims to improve bitcoin. Compared with bitcoin, lightcoin has three significant differences. First, the lightcoin network can process a block every 2.5 minutes (instead of 10 minutes), so it can provide faster transaction confirmation. Second, the lightcoin network is expected to proce 84 million lightcoins, four times the amount of money issued by bitcoin network. Thirdly, the scrypt encryption algorithm first proposed by Colin Percival is used in lightcoin's workload proof algorithm, which makes it easier to mine lightcoin on ordinary computer than bitcoin. Each Leyte is divided into 100000000 smaller units, defined by eight decimal places

1. Transaction:
it's easier to use, larger in volume and greater in appreciation potential. The block confirmation time is shorter, which is four times faster than bitcoin. For example, pizza owners are more willing to accept LTC payment to save transaction time< mining:
special algorithm creates the unique charm of LTC, which is also the key to stand out from Shanzhai coins. Scrypt algorithm uses sha256 as its subroutine, and scrypt itself needs a lot of memory, each hash is used as the input seed, and then needs a lot of memory to store another seed pseudo-random sequence, Generate pseudo-random points of sequence and output hash value. The key is that scrypt algorithm needs a lot of memory while sha256 algorithm does not. So in this era when BTC mining of graphics card is coming to an end, LTC mining is about to usher in a golden period of development. Because of the high cost of memory, any ASIC or FPGA has no advantage over graphics card mining. LTC has advantages, at least in the foreseeable future
3. The biggest threat of bitcoin is 51% attack:
some shanzhais are killed by 51% attack. To be honest, LTC is a worry for the development of LTC and BTC, of course. However, the specific problems they face are different: BTC can avoid 51% attack through technology upgrading (such as end block reconstruction, careful node upgrading, and calculation difficulty), However, there is no way to evade LTC technology. However, e to the scattered computing power of graphics card mining and the increasing difficulty, this problem needs to be paid attention to, but don't worry too much. With the use of ASIC in BTC, the risk of 51% attack is increasing. I hope BTC development team can solve this problem as soon as possible.
POW: full name of proof of work
pos: proof of stake
both of them are the consensus mechanism of blockchain and the bookkeeping method of digital currency
the difference is:
1. POW mechanism: workload proof mechanism, that is, the proof of workload, is the requirement that must be met when generating a new transaction information (that is, a new block) to be added to the blockchain. In the blockchain network based on workload proof mechanism, the ability of nodes to obtain the correct numerical solution to generate blocks by calculating the numerical solution of random hash hash is the specific performance of node computing power
POS mechanism: the proof of rights and interests requires the certifier to provide a certain amount of ownership of cryptocurrency. The operation mode of the proof of rights and interests mechanism is that when creating a new block, the miners need to create a "currency right" transaction, and the transaction will send some coins to the miners themselves according to the preset proportion. According to the proportion and time of token owned by each node, the equity proof mechanism reces the mining difficulty of nodes proportionally according to the algorithm, so as to speed up the speed of searching for random numbersextended materials:
the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's ideas, the open source software and the P2P network on it were designed and released. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction
litecoin is short for LTC, and its English name is litecoin. Litecoin stands for lightweight. The meaning behind litecoin is lightweight currency
1. Bitcoin generates a block every 10 minutes, while lightcoin LTC generates a block every 2.5 minutes. This means that lightcoin has faster transaction confirmation efficiency. Bitcoin transfer sometimes takes 1 hour or even longer to arrive at the account, but lightcoin generally takes less than 20 minutes to confirm
2. Since the LTC speed of lightcoin is four times that of bitcoin, and the reward of each block is the same as bitcoin, the total amount of money is four times that of bitcoin, which is 84 million lightcoins, which is higher than that of bitcoin<
3. Bitcoin adopts sha256 encryption algorithm, and lightcoin adopts script encryption algorithm. Compared with bitcoin, lightcoin LTC has a slightly lower computational load, which makes it easier to mine and more suitable for graphics card
(GPU) operation. At the same time, FPGA (field programmable gate array) and ASIC (application specific integrated circuit) implemented for script are better than sha256 used for bitcoin, More expensive.
많 &# 44256;
first of all, the topic is not right. Now there are all kinds of currencies on the exchange, whether it's big platforms like Qube, or small ones like coin an, or competitive ones like Shanzhai coins. They are not all POS models
for example, LTC is a variant of crypt algorithm pow, dogcoin is a variant of pow, and auxpow is a fusion mining algorithm
Dashi coin is the pow of X11 algorithm, Ethereum is the pow of ethash algorithm, and Diandian coin is the pow + POS simultaneous mining. Now the new Shanzhai coin is mostly the early POW + late POS mode, the reason is 1, the early POW is to avoid uneven distribution. 2. In the later stage, POS can't win in the pow competition, but the computing power is low, and POW is easy to be attacked by 51
that is, only from the perspective of security: high computing power pow (including auxpow like dog coin) & gt; POS> Low computing power pow
New energy sharing vehicles can go to high speed. On February 17, 2016, China's first charging card was sold in Changzhou, Jiangsu Province, which means that high-speed electric vehicles have become a reality
in 2015, the State Grid Corporation of China invested heavily in the field of electric vehicle charging network with reasonable layout. Now the "two vertical, two horizontal and one ring" expressway electric vehicle charging network of Beijing Shanghai, Beijing Hong Kong Macao, Qingyin, Shanghai Cheng and Beijing Shanghai Hangzhou ring lines has been completed and put into operation
At present, as many as 59 fast charging stations have been put into use along the expressway in Jiangsu Province, and the distribution network of charging cards, which includes 64 power supply outlets in Jiangsu Province, was officially put into operation on February 4, 2016new energy sharing vehicles can be used on expressways, but they will face charging problems after a long journey. Considering that there are few or no charging piles on expressways, it is recommended to use them in urban areas
extended data:
high speed traffic police: new energy vehicles can get on the high speed if they meet the conditions
among the expressways in Zhejiang Province, the minimum speed limit is 60km, and the new energy vehicles that meet the conditions can get on the high speed. The reporter inquired about the new energy vehicles on sale in the market and found that the speed of 60 km / h is easy for them to reach, so the speed is not a problem
police officer Yu of Hangzhou high speed traffic police detachment explained that as long as the new energy vehicle can maintain a speed of more than 60 km / h and hang a regular license plate, it is no problem to get on the road, and the traffic police have no reason to stop it. He said that the high-speed traffic police occasionally see new energy vehicles such as Tesla on the high-speed, so netizens' thoughts are too much< br />

work. Chinese translation is workload proof, which is a decentralized, open, transparent and tamper proof algorithm mechanism. Bitcoin is based on the pow consensus algorithm, which has been running safely and smoothly for 10 years. At present, etc also adopts this algorithm mechanism, and it can get rewards through computing power mining.
