Litecoin is an open-source peer-to-peer cryptocurrency launched in 2011 as an alternative implementation of digital money inspired by Bitcoin. It uses its own blockchain, Proof-of-Work consensus and native currency, LTC, while changing several network parameters—including the mining algorithm, block interval and total coin supply.
Charlie Lee announced Litecoin on October 9, 2011, and the network’s genesis block was mined several days later. Litecoin was derived from Bitcoin’s open-source code but adopted Scrypt rather than Bitcoin’s SHA-256 mining algorithm and targeted blocks approximately every 2.5 minutes instead of every 10 minutes.
More than a decade later, Litecoin remains actively maintained. The network has also evolved beyond its early Bitcoin-derived design through upgrades such as Segregated Witness and MimbleWimble Extension Blocks, or MWEB.
How Litecoin works#
Litecoin maintains a public blockchain containing the history of confirmed LTC transactions.
When someone sends LTC, their wallet creates and signs a transaction using the private keys controlling the coins being spent. That transaction is broadcast across Litecoin’s peer-to-peer network and can then be included in a block by miners.
Miners compete to produce valid Proof of Work. Once a block is found, independently operated Litecoin nodes verify that the block and its transactions follow the network’s consensus rules before accepting it.
LTC is the network’s native currency. It is used for peer-to-peer transfers, transaction fees and miner rewards rather than being issued as a token on another blockchain.
Scrypt Proof of Work#
Litecoin uses Scrypt Proof of Work rather than Bitcoin’s SHA-256 mining algorithm.
The current Litecoin specification uses Scrypt with parameters N=1024, r=1 and p=1. Miners repeatedly perform the required computation while searching for a block hash that satisfies the network’s difficulty target.
When Litecoin launched, Scrypt’s relatively memory-intensive design made it attractive to GPU miners and differentiated the network from Bitcoin’s increasingly specialized SHA-256 mining ecosystem.
That historical point is sometimes misunderstood today.
Litecoin is no longer meaningfully ASIC-resistant. Specialized Scrypt ASIC miners now outperform CPUs and GPUs by a large margin, and Litecoin’s own educational material identifies ASIC hardware as the most efficient method for directly mining the network.
So describing modern Litecoin as a coin efficiently mined on ordinary consumer hardware would be outdated.
Litecoin and Dogecoin merged mining#
Litecoin also has an unusual relationship with Dogecoin.
Since 2014, Dogecoin has supported Auxiliary Proof of Work, allowing Scrypt miners to merge-mine LTC and DOGE. A compatible mining operation can contribute Proof of Work toward both networks rather than choosing only one.
This does not combine Litecoin and Dogecoin into one blockchain. They maintain separate ledgers, monetary policies and cryptocurrencies, but compatible mining work can contribute to both networks. Litecoin’s current educational material continues to document LTC/DOGE merged mining.
Why are Litecoin blocks faster than Bitcoin blocks?#
Litecoin targets a block approximately every:
2.5 minutesBitcoin, by comparison, targets roughly 10-minute blocks.
This means new Litecoin blocks are expected more frequently, although an individual transaction’s practical settlement time depends on factors such as the number of confirmations a recipient requires and current network conditions.
A 2.5-minute block target is four times shorter than Bitcoin’s 10-minute target, but that does not mean every real-world payment is automatically four times faster or equally secure after the same number of confirmations.
Litecoin’s 84 million LTC supply#
Litecoin uses a predetermined issuance schedule derived conceptually from Bitcoin’s model.
The network was designed with a maximum supply of:
84,000,000 LTCThe original mining reward was 50 LTC per block. Litecoin halves its block subsidy every 840,000 blocks, which occurs approximately once every four years because of the network’s shorter block interval.
The current block subsidy is:
6.25 LTCFollowing the 2023 halving, miners receive 6.25 newly issued LTC per block before transaction fees. Future halvings will continue reducing the subsidy until issuance approaches the 84 million LTC limit.
Are Litecoin transaction fees always low?#
Litecoin is commonly associated with relatively inexpensive transactions, but fees should not be presented as permanently fixed or guaranteed.
Users attach transaction fees to compensate miners for including their transactions in blocks. Fee requirements can vary with transaction size, wallet behavior and demand for available block space.
Litecoin’s shorter block interval and available capacity have historically contributed to relatively inexpensive on-chain transfers, but Scrypt itself is not the reason transaction fees are lower.
Mining algorithm choice and transaction-fee economics are separate parts of the protocol.
What is MWEB?#
One of Litecoin’s most significant differences from Bitcoin today is MimbleWimble Extension Blocks (MWEB).
MWEB became part of Litecoin Core through the 0.21.2 release and adds an optional extension-block system based on MimbleWimble technology. It is intended to improve fungibility, transaction privacy and blockchain scalability without forcing every Litecoin transaction to use the privacy layer.
Users can peg LTC into MWEB and perform transactions where information such as transferred amounts is obscured compared with ordinary transparent Litecoin transactions.
MWEB should not be described as making all Litecoin activity private.
The standard Litecoin blockchain remains publicly visible, while MWEB is an optional transaction environment. Litecoin therefore differs from privacy-focused cryptocurrencies where privacy protections may be mandatory across the entire network.
MWEB remains under active maintenance. Litecoin Core v0.21.5.8, released in September 2026, included additional improvements to MWEB validation, relay, mining and resource management.
SegWit and the Lightning Network#
Litecoin has also played an important role in testing technologies associated with Bitcoin.
Litecoin activated Segregated Witness (SegWit) before Bitcoin in 2017. SegWit changes how transaction-signature data is represented and resolved transaction malleability issues that complicated certain higher-layer payment protocols.
The network has also supported Lightning Network implementations, allowing compatible users to create payment channels where multiple transactions can occur away from the base blockchain before final settlement.
These technologies highlight an important feature of Litecoin’s development history: although its architecture remains closely related to Bitcoin, Litecoin has sometimes adopted compatible protocol changes earlier.
Litecoin is public, not inherently anonymous#
Ordinary Litecoin transactions take place on a public blockchain.
Addresses do not automatically contain someone’s real-world name, but transactions, balances and blockchain history can be inspected publicly. That makes standard Litecoin use more accurately described as pseudonymous rather than anonymous.
MWEB provides an optional layer for users seeking stronger transaction privacy, but it does not make every Litecoin transaction private by default.
Users should therefore distinguish between:
standard Litecoin transactions — publicly visible on the base blockchain
and
MWEB transactions — designed to conceal additional transaction information.
Who controls Litecoin?#
Litecoin does not have a company with unilateral authority over the network.
Litecoin Core is open-source software, and developers can publish proposed changes, but independently operated nodes and miners ultimately choose which software and consensus rules they run.
The Litecoin Foundation supports development, education and ecosystem activity, but it does not own the blockchain or possess the ability to arbitrarily alter users’ balances.
Like Bitcoin, Litecoin depends on coordination among developers, miners, node operators, businesses and users rather than a single network administrator.
Is Litecoin just a Bitcoin clone?#
Calling Litecoin simply a Bitcoin clone misses how the network has evolved.
Its earliest code was heavily derived from Bitcoin, and the two systems continue to share many concepts:
- UTXO-based accounting
- Proof-of-Work consensus
- capped issuance
- periodic mining halvings
- public transaction verification
- open-source node software
But Litecoin uses different network parameters, Scrypt mining, a 2.5-minute block target and an 84 million LTC supply.
MWEB has also created a substantial protocol-level difference from Bitcoin’s current base layer.
So Litecoin is best understood as a Bitcoin-derived independent blockchain, not a token or alternative front end for Bitcoin.
Litecoin’s trade-offs#
Litecoin’s design comes with trade-offs.
Its Proof-of-Work network requires specialized mining equipment and ongoing energy expenditure. LTC’s market price can fluctuate substantially, and the protocol does not attempt to maintain a stable exchange rate.
Transactions are also difficult to reverse after confirmation. There is no central Litecoin authority capable of restoring funds if a user loses private keys or sends LTC to the wrong destination.
Standard transactions remain publicly traceable, while MWEB privacy is optional and requires compatible wallet and service support.
And while Litecoin has a long operating history, longevity does not eliminate software, custody, mining-concentration or market risks.
Is Litecoin still being developed?#
Yes.
Litecoin Core remains actively maintained. The project’s GitHub repository continued receiving releases throughout 2026, including Litecoin Core v0.21.5.8 in September. That release included MWEB validation, transaction-relay, mining and resource-management improvements.
How to research Litecoin independently#
Users can independently inspect Litecoin’s source code, run a full node, review blockchain transactions and study the network’s protocol documentation.
The strongest starting points include Litecoin’s official website, Litecoin Core repository, Learning Center and MWEB documentation.

Final perspective#
Litecoin is one of the longest-running cryptocurrency networks still in active use.
Its architecture began as a modified Bitcoin implementation, but differences such as Scrypt Proof of Work, 2.5-minute blocks, an 84 million LTC cap, merged mining with Dogecoin and optional MWEB transactions have given Litecoin a distinct technical identity.
Its longevity does not mean every old claim about Litecoin remains accurate. Modern mining is dominated by Scrypt ASICs, transaction fees are not determined by the mining algorithm, and MWEB introduces privacy capabilities that did not exist during Litecoin’s early years.
Understanding those distinctions provides a much more useful picture of Litecoin than the familiar shorthand of simply calling it “silver to Bitcoin’s gold.”
