中亿财经网8月28日讯，莱特币是什么?莱特币，英文叫Litecoin，简称LTC，诞生于2011年11月9日，创始人是查理·李(Charlie Lee)。莱特币的宗旨是改进比特币，所以它和比特币有很多相似之处，在行业中有“比特金，莱特银”的说法。相较比特币，莱特币总量更大一些，确认速度更快一些。
On August 28, the Middle Billion Financial Network, what's Leitcoin? Letcoin, an English name called LTC, was born on November 9th, 2011 and founded by Charlie Lee. The purpose of Letcoin is to improve bitcoin, so it has a lot of similarities with bitcoin, and in the industry there is the term "bitcoin, Lightcoin."
莱特币总量是比特币的四倍，8400万枚;它的产量减半时间和比特币一样都是4年;它的共识机制和比特币一样都是工作量证明机制(PoW);它的区块时间是2.5分钟，是比特币的四分之一，每2.5分钟打包一个区块;莱特币的区块奖励最早是50枚莱特币，截止目前(2018年1月)莱特币区块奖励为25莱特币，已发行量约为5400万。
The total amount of Leitco is four times that of Bitcoin, 84 million; its production is reduced by half as much as that of Bitcoin for four years; its consensus mechanism and Bitcoin are the workload certification mechanism (PoW); its block time is 2.5 minutes, one quarter of Bitcoin, and a block is packed every two and a half minutes; and its block reward is as early as 50 Letcoons, and as of now (January 2018) the Lightcoin block is about 25 LEtcoins, with a circulation of about 54 million.
莱特币受到了比特币(BTC)的启发，并且在技术上具有相同的实现原理，莱特币的创造和转让基于一种开源的加密协议，不受到任何中央机构的管理。莱特币旨在改进比特币，与其相比，莱特币具有三种显著差异。第一，莱特币网络每2.5分钟(而不是10分钟)就可以处理一个块，因此可以提供更快的交易确认。第二，莱特币网络预期产出8400万个莱特币，是比特币网络发行货币量的四倍之多。第三，莱特币在其工作量证明算法中使用了由Colin Percival首次提出的scrypt加密算法，这使得相比于比特币，在普通计算机上进行莱特币挖掘更为容易。每一个莱特币被分成100,000,000个更小的单位，通过八位小数来界定。
Lightcoin is inspired by the Bitcoin (BTC) and technically has the same rationale for realization, and its creation and transfer are based on an open source encryption agreement that is not regulated by any central agency. Leitco is designed to improve bitcoin, which has three significant differences compared to it. First, the Lightcoin network can handle one block every 2.5 minutes (rather than 10 minutes), thus providing faster confirmation of transactions. Second, the Letco network is expected to produce 84 million Letco, four times more than the amount of currency issued by the Bitcoin network. Third, the Letco used the Scrypt encryption method first proposed by Colin Percival in its workload certificate, which makes it easier to do Letco digging on a regular computer than Bitcoin.
它基于比特币(Bitcoin)协议，但不同于比特币的地方在于，即使在现阶段，通过消费级的硬件也可以高效地“挖矿”。Litecoin提供给您更快速的交易确认(平均2.5分钟)，它使用硬内存以及基于scrypt(一种加密算法)的挖矿工作量证明算法，面向大多数人使用的普通计算机及图形处理器(GPU)。Litecoin网络预期将生产8400万个货币单位。
It is based on the Bitcoin agreement, but unlike Bitcoin, even at this stage, it can be “mining” efficiently through consumer-grade hardware. Litecoin provides you with faster transaction confirmation (average of 2.5 minutes), using hard RAM and a certificate of mining workload based on Scrypt (a cryptography algorithm), a common computer and graphic processor (GPU) for most people. The Litecoin network is expected to produce 84 million monetary units.
Litecoin的设计目的之一是提供一种挖掘算法，使它能够在挖掘比特币的机器上被同时运行。为挖掘比特币而设计的专用集成电路(ASIC)逐渐兴起的同时，Litecoin也紧跟着技术演变。但在Litecoin货币被广泛应用之前，不太可能会出现专门为Litecoin设计的专用集成电路(ASIC)。
One of the aims of Litecoin’s design is to provide an algorithm that allows it to operate simultaneously on the machines that dig bitcoin. As the specialized integrated circuits (ASICs) designed to dig bitcoins rise, Litecoin follows technology.
交易
Transactions
由一个类似于比特币的点对点网络，通过Scrypt工作量证明方案来处理莱特币交易、结余以及发行(当一个足够小的哈希值被发现时，一个块就会被创建，此时莱特币就会被发行，而发现这个哈希值和创建块的过程被称作“挖矿”)。莱特币的发行速率按照等比数列，每四年(每840,000个块)减少一半，最终达到总量8400万个LTC。不同于比特币，Scrypt所具有的内存密集特性让莱特币更适合用图形处理器(GPU)进行“挖矿”。为Scrypt实施的FPGA(现场可编辑逻辑门阵列)和ASIC(专用集成电路)，相比于比特币使用的sha256，更为昂贵。
A point-to-point network similar to Bitcoin, through the Scrypt workload proof programme, handles the transactions, balances and issuance of Lightcoin (a block is created when a small Hashi value is found, and then it is released, and the process of creating it is known as “mining”). The distribution rate of Lightcoin is reduced by half every four years (every 840,000 units) to a total of 84 million LTCs. Unlike Bitcoin, the built-in characteristics of Scrypt make it better “mining” by graphic processors (GPUs). The FPGA (on-site compilation of logical arrays) and ASIC (specialized circuits) implemented for Scrypt are more expensive than the sha256 used in Bitcoin.
莱特币当前可以交换法定货币以及比特币，大多数通过线上交易平台。可撤销的交易(比如用信用卡进行的交易)一般不用于购买莱特币，因为莱特币的交易是不可逆的，因此带来了退款风险。
At present, it is possible to exchange legal currency as well as bitcoins, mostly via online trading platforms. Revocable transactions (e.g., transactions with credit cards) are generally not used for the purchase of Lightcoins, because they are irreversible and therefore pose a risk of refunds.
