Litecoin (sign: Ł; abbrv: LTC) is a peer-to-peer cryptocurrency and open source software project released under the MIT/X11 license. Inspired by and technically nearly identical to Bitcoin (BTC), Litecoin creation and transfer is based on an open source encryption protocol and is not managed by any central authority. Litecoin is intended to improve upon Bitcoin and offers three key differences. Firstly, the Litecoin network processes a block every 2.5 minutes, rather than every 10 minutes, which allows for the faster confirmation of transactions. Secondly, the Litecoin network will produce 84 million litecoins which is four times as many as currency units as will be issued by the Bitcoin network. Thirdly, Litecoin uses scrypt in its proof-of-work algorithm: a sequential memory-hard function first conceived by Colin Percival, that makes mining easier to carry out on normal computers. Each litecoin is subdivided into 100,000,000 smaller units, defined by eight decimal places.

Transactions

A peer-to-peer network similar to Bitcoin's handles Litecoin's transactions, balances and issuance through Scrypt, the proof-of-work scheme (Litecoins are issued when a small enough hash value is found, at which point a block is created, the process of finding these hashes and creating blocks is called mining). The issuing rate forms a geometric series, and the rate halves every 4 years (every 840,000 blocks) reaching a final total of 84 million LTC. The memory intensive nature of Scrypt means that unlike with Bitcoin, Litecoin is better suited for GPU mining. FPGA and ASIC implementations are more expensive to create for Scrypt than for SHA-256 as used by Bitcoin.

Litecoins are currently traded for both fiat currencies and bitcoins, mostly on online exchanges. Reversible transactions (such as those with credit cards) are not normally used to buy litecoins as Litecoin transactions are irreversible, so there is the danger of chargebacks. As of 28th April 2013, 1 LTC is worth approximately 4.11 USD or 0.032 BTC. This makes Litecoin the second largest cryptocurrency by market cap with a cap of 70,000,000 USD.

History

Litecoin was released via an open-source client on Github on October 7th 2011. The current version of this client (as of 19th April 2013) is v0.6.3c.

Other clients have also been released.

More recently Litecoin has been covered in the news as a Bitcoin alternative.

Development

The Litecoin Developers have a new release 0.8.1 in the works which will help to modernize and enhance the network. This major upgrade will include all enhancements made in recent Bitcoin releases.

Redundancy

Some believe that Litecoin does not provide any features over what Bitcoin already provides, so they believe Litecoin is unlikely to match or surpass Bitcoin's value or user base.

Vulnerability to mining monopoly

Similarly to Bitcoin, Litecoin can be attacked by an entity that can match or exceed the hash rate of the network, though such a 51% attack becomes more difficult to launch and maintain as the hash rate of the network grows. Some have argued that because Litecoin is designed to be inefficient on all common computers, a malicious entity need only produce a small batch of specialized hardware to overtake all the commodity mining systems combined. On the other hand, others have argued that the scrypt function simply makes it infeasible to create any specialised hardware; and that even if it were possible, specialised hardware would only strengthen the network, which happened with Bitcoin and ASICs.

Pump and Dump Scheme

Some people claim that Litecoin is a pump and dump scheme, rewarding those who get in sooner at the expense of those who adopt it just before the price falls.
