Litecoin (Abbreviation:LTC;sign:Ł) is a decentralizedpeer-to-peercryptocurrency andopen-source software project released under theMIT/X11 license. Inspired byBitcoin, Litecoin was among the earliestaltcoins, starting in October 2011.[4][5] In technical details, the Litecoin main chain shares a slightly modifiedBitcoin codebase. The practical effects of those codebase differences are lower transaction fees,[6] faster transaction confirmations,[5] and faster mining difficulty retargeting. Due to its underlying similarities to Bitcoin, Litecoin has historically been referred to as the "silver to Bitcoin's gold."[7][8][9] In 2022, Litecoin added optional privacy features via softfork through the MWEB (MimbleWimble extension block) upgrade.[9][10]
By 2011, Bitcoin mining was largelyperformed by GPUs.[11] This raised concern in some users that mining now had a high barrier to entry, and thatCPU resources were becoming obsolete and worthless for mining. Using code from Bitcoin, a new alternative currency was created calledTenebrix (TBX). Tenebrix replaced theSHA-256 rounds in Bitcoin's mining algorithm with thescrypt function,[12] which had been specifically designed in 2009 to be expensive toaccelerate with FPGA or ASIC chips.[13] This would allow Tenebrix to have been "GPU-resistant", and utilize the available CPU resources from bitcoin miners. Tenebrix itself was a successor project to an earlier cryptocurrency which replaced Bitcoin's issuance schedule with a constant block reward (thus creating an unlimited money supply).[12] However, the developers included a clause in the code that would allow them to claim 7.7 million TBX for themselves at no cost, which was criticized by users.[14]
To address this,Charlie Lee, aGoogle employee who would later become engineering director atCoinbase,[15] created an alternative version of Tenebrix calledFairbrix (FBX).[4] Litecoin inherits the scrypt mining algorithm from Fairbrix, but returns to the limited money supply of Bitcoin, with other changes.
After launch, the early growth of Litecoin was aided by its increasing exchange availability and liquidity on early exchanges such asBTC-e. During the month of November 2013, the aggregate value of Litecoin experienced massive growth which included a 100% leap within 24 hours.[17][18]
In early 2014, Lee suggested merge mining (auxPOW)Dogecoin with Litecoin to the Dogecoin community at large. In September 2014, Dogecoin began merge-mining with Litecoin.[19]
In 2020,PayPal added the ability for users to purchase a derivative of Litecoin along withBitcoin,Ethereum, andBitcoin Cash which could not be withdrawn or spent as part of its Crypto feature.[20][21]
In September 2021, a fake press release was published onGlobeNewswire announcing a partnership between Litecoin andWalmart. This caused the price of Litecoin to increase by around 30%, before the press release was revealed as a hoax.[22]
In May 2022, MWEB (Mimblewimble Extension Blocks) upgrade was activated on the Litecoin network as asoft fork. This upgrade provides users with the option of sending confidential Litecoin transactions, in which the amount being sent is only known between the sender and receiver.[23][non-primary source needed]
The targeted block time is every 2.5 minutes for Litecoin, as opposed to Bitcoin's 10 minutes. This allows Litecoin to confirm transactions four times faster than Bitcoin.[25]
Scrypt, an alternativeproof-of-work algorithm, is used for Litecoin. According toMotherboard, "Scrypt was chosen because it theoretically prevents the use of ASICs, those specialized chips that greatly increase mining power and efficiency (though there is debate over the validity of this claim).".[26]
Litecoin is merge mined with another prominent cryptocurrency, Dogecoin.[27]
Litecoin has a maximum circulating supply of Ł84,000,000, which is four times larger than Bitcoin's maximum circulating supply of₿21,000,000.[citation needed]
MWEB optional privacy was added to Litecoin's base layer in May 2022 via soft fork.[10] This allows amounts held within wallets and transaction amounts within MWEB to be private.[28]
