Lightcoin 51 attack
was released on October 7, 2011. It is currently the highest market value counterfeit coin, about 1% of BTC's market value, or US $1000W. Compared with BTC, LTC is faster, with an average of 2.5 minutes and 6 confirmations per block in 15 minutes. In addition, the number of LTCs is four times that of BTCs, with a total of 8400w. At present, LTC uses scrypt algorithm, which needs a lot of memory support. The professional mining machine on the market can not be used for LTC mining, only the graphics card
what is the difference between lightcoin and bitcoin
1. Transaction: easier to use, larger volume and greater 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.
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
in technology, lightcoin has almost the same implementation principle as bitcoin. It is based on an open source encryption protocol in the process of creation and transfer. Like bitcoin, lightcoin is also not managed by the central authorities
as we all know, bitcoin is proced through mining machine. The Leyte coin is also proced by "mining". In the whole mining process of Leyte coin, the computer graphics card will carry out the relevant hash operation. When our "miner" calculates the "burst value", you can get 50 Leyte coins. However, with the continuous growth of the computing power of Wright coin, it is not possible to use a few "mining machines" to dig Wright coin. Therefore, it can only be added to the "ore pool", so that all the calculation power can be collected, and the "ore burst value" can be calculated more easily
the expected total number of online currencies for lightcoin is 84 million, which is four times the amount of online currencies issued by bitcoin. We can use Leyte currency to exchange legal currency and bitcoin. In general, it is through online trading platform. Since the transaction of Leyte coin is irreversible, the revocable transaction cannot be carried out, because it will bring the risk of refund.

today, the price of bitcoin shows a small floating decline again. At present, the price of bitcoin is below 2800 yuan. However, e to the joint mining of dog coin and the surge of computing power, dog coin has escaped 51% of the attack. Therefore, dog coin has almost doubled by more than 3% and once rose to 3%. Today, dog coin and some other counterfeit coins show a small floating growth. Of course, bitstocks are also black horses
it is said that bitcoin will enter the cold winter, and the violent era of bitcoin mining has come to an end, and mining is almost close to the cost. The founder of Avalon mining machine also said that at present bitcoin mining is basically determined by electricity price. Avalon's generation 4 28nm chip does rece energy consumption a lot.
because the connected computers are controlled by the policy settings of the router
the most important thing is to allocate your bandwidth reasonably. In theory, if you download resources from a computer in your network segment, if your router does not allocate bandwidth, it may cause the computers in the whole network segment to get stuck on the Internet
if the distribution is reasonable and the router is powerful, then 200 computers can be easily handled.
