Litecoin: A History of the Silver to Bitcoin's Gold

Charlie Lee, a Google employee, released Litecoin via an open-source client on GitHub on October 7, 2011. Litecoin was a fork of the Bitcoin codebase but replaced Bitcoin's SHA-256 mining algorithm with Scrypt, which was designed to be more resistant to ASIC mining and allowed CPU miners to participate. Litecoin became the first major alternative cryptocurrency after Bitcoin.

Litecoin's aggregate value experienced massive growth, including a 100% leap within 24 hours, pushing its market capitalization past USD 1 billion for the first time. The surge established Litecoin as the second most valuable cryptocurrency after Bitcoin and solidified its reputation as "the silver to Bitcoin's gold."

Following a proposal from Charlie Lee earlier in 2014, Dogecoin began merge-mining with Litecoin using the AuxPoW (auxiliary proof-of-work) protocol. The arrangement allowed Dogecoin miners to simultaneously mine Litecoin, increasing security for both networks and creating one of the earliest examples of blockchain interoperability.

Litecoin experienced its first halving at block height 840,000, reducing the block reward from 50 LTC to 25 LTC. The event cut the rate of new LTC issuance in half, transitioning Litecoin into a more scarce asset and testing the network's economic model for the first time.

Litecoin founder Charlie Lee announced he had sold all of his personal LTC holdings, citing a conflict of interest. Lee stated that his stake in Litecoin created a conflict whenever he commented on the price and that selling removed that conflict, allowing him to focus purely on development without personal financial considerations.

Litecoin underwent its second halving at block height 1,680,000, cutting the block reward from 25 LTC to 12.5 LTC. The event was preceded by significant market speculation and price appreciation in the months leading up to the halving.

PayPal added the ability for users to purchase, hold, and sell Litecoin alongside Bitcoin, Ethereum, and Bitcoin Cash through its platform. The integration exposed millions of PayPal users to Litecoin, though initially users could not withdraw their crypto to external wallets.

The Mimblewimble Extension Blocks (MWEB) upgrade was activated on the Litecoin network as a soft fork, introducing optional confidential transactions. The upgrade allowed users to send transactions where the amount was known only between sender and receiver, enhancing privacy on the Litecoin blockchain while maintaining auditability.

Litecoin underwent its third halving at block height 2,520,000, reducing the block reward from 12.5 LTC to 6.25 LTC. With a total supply capped at 84 million LTC, the halving continued Litecoin's deflationary monetary policy, further reducing newly issued supply entering circulation.
