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 be an alternative cryptocurrency to 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 less-sophisticated computers than Bitcoin requires. 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 sha256 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 25 April 2013, 1 LTC is worth approximately 3.97 USD or 0.028 BTC. This makes Litecoin the second largest cryptocurrency by market cap with a cap of 35,000,000 USD.
