Lightcoin ASIC

1. What is a Leyte coin? To put it simply, litecoin (LTC)
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.

2. Lightcoin aims to improve bitcoin. Compared with bitcoin, lightcoin has three advantages:
① lightcoin network can process a block every 2.5 minutes (instead of 10 minutes), so it can provide faster transaction confirmation
② lightcoin network is expected to proce 84 million lightcoins, which is about four times the circulation of bitcoin network
③ in its workload proof algorithm, lightcoin uses scrypt encryption algorithm first proposed by Colin Percival, which makes it easier to mine lightcoin on ordinary computer than bitcoin
lightcoin is the most successful digital currency to imitate bitcoin. At present, major platforms support lightcoin transactions, including 58coin. It can be seen that lightcoin is comparable to bitcoin in terms of security and recognition.

3. Ethereal currency and Leyte currency are relatively reliable counterfeit currencies, and their market value and influence are second only to bitcoin
in addition, there are Ruibo coin, Ruitai coin, vitality coin, dog coin and other excellent counterfeit coins.

Litecoin (LTC, currency symbol: 321;) It is based on & quot; Point to point & quot It is also an open source software project under MIT / X11 license. It can help users make instant payments to anyone in the world

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

extended materials:

it is based on bitcoin protocol, but different from bitcoin, it can be & quot; efficiently implemented by consumer hardware; Mining & quot;. Liteoin provides you with faster transaction confirmation (2.5 minutes on average). It uses hard memory and mining workload proof algorithm based on scrypt (an encryption algorithm). It is oriented to ordinary computer and graphics processor (GPU) used by most people. The litecain network is expected to proce 84 million currency units

one of the design purposes of litecoin is to provide a mining algorithm, which can be run simultaneously on the bitcoin mining machine. With the rise of application specific integrated circuits (ASIC) designed for bitcoin mining, litecoin is also closely following the technological evolution. But before the widespread use of litecoin currency, it is unlikely that there will be an application specific integrated circuit (ASIC) specially designed for litecoin[ 1]

a peer-to-peer network, similar to bitcoin, processes transaction, balance and issue of lightcoin through script workload proof scheme (when a sufficiently small hash value is found, a block will be created and lightcoin will be issued, and the process of discovering the hash value and creating the block is called & quot; Mining & quot;). The issuing rate of Leyte coins is reced by half every four years (every 840000 pieces) according to the proportional sequence, and finally the total number of LTCs is 84 million. Unlike bitcoin, the memory intensive feature of script makes it more suitable to use graphics processor (GPU) for & quot; Mining & quot;. FPGA (field programmable gate array) and ASIC (application specific integrated circuit) implemented for script are more expensive than sha256 used for bitcoin

currently, lightcoin can exchange legal tender and bitcoin, most of which are through online trading platforms. Revocable transactions (such as credit card transactions) are generally not used to purchase Leyte, because Leyte transactions are irreversible, which brings the risk of refund. As of April 25, 2013, a Leyte is worth about $3.97 or 0.028 bitcoin. This makes Leyte the second largest electronic currency with a market value of about $35 million

5. 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< What's the difference between lightcoin and bitcoin:
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:

6. On October 7, 2011, a network organization announced the release of a new P2P virtual currency, called lightcoin (LTC)

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.

7. At present, one view of lightcoin is that it will eventually survive and become an auxiliary currency other than bitcoin. There is a famous slogan on the official website of lightcoin: "bitcoin is gold, lightcoin is silver." Another point of view demonstrates that Leyte coin and other counterfeit coins can not succeed from a logical point of view: if the counterfeit coin succeeds, there will be more counterfeit coins, and the proliferation of counterfeit coins will lead to the collapse of value, and people finally find that bitcoin is the best way to maintain its value; If Shanzhai coin is not successful, there will be no imitators, and the failed Shanzhai coin will eventually disappear. The author tends to think that cryptography currency will eventually become an important member of the world's mainstream currency, and bitcoin is not necessarily the only one, just like the coexistence of US dollar, euro, yen and RMB in real life. There will not be only one kind of cryptocurrency, but there will not be innumerable kinds in the world. In the end, only bitcoin and the other 2-3 counterfeit currencies will survive. In fact, the key to the survival of an open source currency is the public's confidence in it, which comes from its long-term and stable use. In the two years since the invention of Leyte coin, public confidence in it has been graally established. Whether this confidence can be maintained or not, there are still many unstable factors. One of them is that lightcoin is more vulnerable to 51% attacks than bitcoin. Previously, FTC (feather coin), which uses the same algorithm as Wright coin, has been attacked by 51% and led to the collapse of public confidence. In fact, FTC is graally withdrawing from the stage of history. Whether it can resist 51% attacks and survive is a problem that lightcoin must solve. As for whether Leyte can replace bitcoin, we should go a step further: is there a counterfeit coin that can eventually replace bitcoin? The answer is simple: No. In the future, there will probably be a variety of cryptography currencies in the world, but any kind of counterfeit currency can not replace the mainstream position of bitcoin, no matter how excellent its algorithm is compared with bitcoin. We have to admit that bitcoin is not perfect compared with many counterfeit currencies. Its confirmation time is as long as 10 minutes, which is really time-consuming for transactions; 51% attack the sword of Damocles, which is always hanging overhead; From the perspective of environmental protection, the energy consumed by mining is almost wasted. Therefore, many new counterfeit currencies claim that their advantage lies in making up for the defects of bitcoin. But some of the flaws in bitcoin itself are not real. In other words, these defects are deliberately preserved by its inventors after weighing the pros and cons. For example, the 51% attack is rooted in the distributed mining characteristics of bitcoin, a P2P currency. While ripple's XRP currency doesn't need to worry about 51% attacks, and it doesn't need to spend a lot of energy on mining. However, its mode of relying on trust gateway for transaction and centralized currency issuance means that it is very easy to be controlled by government agencies. In addition, even if the design of some counterfeit coins is more ingenious, we should also understand the fact that no matter how excellent the indicators of a proct are, it can not guarantee that it can beat its competitors and achieve success.

8. Compared with bitcoin mining, lightcoin mining is relatively easy. Because the difficulty of mining is relatively low. But at present, lightcoin mining has graally entered the era of ASIC miner competition. The computing power is constantly rising, and the computing power of large mines is approaching 51%. If you want to carry out lightcoin mining, you must buy professional ASIC lightcoin miner. However, the price of lightcoin miner is generally too high, and there will be more ASIC lightcoin miner with high computing power in the future, Computing power is not constantly pushing up. This is the same as the era of bitcoin ASIC miner last year. Last year, Avalon miner was born, which completely subverted the bitcoin mining instry. With the help of roast cat, the computing power suddenly increased, and the graphics card mining completely went out of people's sight. Although there are many bitcoin ASIC mining machines, Avalon mining machine has always been unique and constantly launched its own new procts.
