Add lightcoin
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.
According to the domestic bitcoin, lightcoin trading platform bitcoin China and fire coin network quotation: at present, the price of lightcoin is about 58 yuan
recently, e to the FBI auction of bitcoin and the rumor that the Bank of communications will thoroughly investigate the account number of bitcoin trading platform and the impact of bitcoin core developers' outcry for stagnation in the development of bitcoin basic protocol, the prices of bitcoin and lightcoin have dropped. Among them, the price of lightcoin has not been affected by the rising price of bitcoin. The price is moderate and keeps growing slowly. When the price of bitcoin falls, lightcoin still falls
extended data:
design purpose
based on bitcoin protocol, but different from bitcoin, even at the present stage, it can efficiently "mine" through consumer hardware. 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
at present, lightcoin mining has entered the ASIC era, and the myth that ASIC was not suitable for lightcoin mining has been broken
if you want to mine the Leyte coin, it is recommended that you buy ASIC Leyte coin miner, and you'd better join a mine pool for mining. The more famous lightcoin machines in the market include A2, silverfish, KNC and so on. At present, Avalon, a famous supplier of bitcoin machines, also plans to research and develop lightcoin ASIC chips. Avalon's lightcoin chip is a 28nm process technology, which is in a leading position in the instry.
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 authority. 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.
,
when an object overcomes friction to do work, you need to know
to calculate the work done by a force (including friction)
. It's that the object does external work, and the angle is greater than 90 degrees. This is not the case.
the state of motion has nothing to do with overcoming friction. We can also say that the object is doing work against friction. There are different situations: 1. Putting pressure on the gas is just a change of opinion. Work done to overcome friction is friction multiplied by distance. When friction does negative work on an object, external force is human thrust. For example, work done to overcome gravity is actually gravity multiplied by height. Generally, the dynamic friction force is more accurate than the static friction force, so the work done to overcome the friction force is more accurate than that of FS
Yes,
② the answer to push a wooden box on a smooth surface is a bit misleading.
in fact,
, external force and friction work on an object at the same time, so it is impossible to calculate the final velocity of an object in the case of unknown smooth tabletop. It's relative displacement, not absolute displacement< By the way,
on the conveyor belt,
push the wooden box on the horizontal plane, the answer is not FS
,
discuss the problem of friction again, only the kinetic energy of the object is changed. Of course, there is a difference.
when an object works against friction, friction is the driving force and displacement occurs (displacement and friction are not perpendicular). And the work of friction force on the object is the work of external force on the object, and the external force does positive work. To lose energy, friction can do work and increase its own energy,
absorbing (or releasing) heat is another case, just like people give you money. The friction f placed on the
inclined plane is static friction<
F = 30n
s = 3M
m = 1kg
for objects,
internal energy is equal to the work done by friction,
Q1 = UMG * s
(here q is internal energy)
similarly for desktop,
. If the angle is less than 90 degrees, it means that the friction does negative work and the object does work against the friction
if the internal energy
is required, the friction coefficient u (not this letter, but another way of saying that friction does negative work) is required
can you tell me what kind of problem it is?. Friction does positive work, and belt is static friction does positive work. Friction does positive work. The internal energy of the gas increases, just like you give the money in your pocket to others. It is a kind of situation that an object overcomes friction to do work. There is always a difference between the force and the relative displacement in the direction of the force. That is, the object is subject to friction (which can be a component force), and the friction is resistance,
