Litecoin (LTC): What Is It? Definition & Explanation
Litecoin (LTC) is one of the original Bitcoin alternatives, forked from Bitcoin in October 2011 by former Google engineer Charlie Lee. With a block time four times faster than Bitcoin (2.5 minutes), a maximum supply of 84 million LTC, and the Scrypt mining algorithm, Litecoin has long been positioned as "digital silver" — designed for everyday small payments.

Litecoin is one of the oldest active alternative cryptocurrencies, forked from the Bitcoin source code in October 2011 by former Google engineer Charlie Lee. Lee's core goal was to preserve Bitcoin's robustness and security model while delivering a faster, cheaper alternative for everyday transactions. This is why Litecoin has long been dubbed "digital silver to Bitcoin's digital gold."
Founding and History
Charlie Lee published Litecoin as open source on GitHub in 2011. The fork was based on Bitcoin Core 0.3.19.2; the key changes were to block time, mining algorithm, and maximum supply. Lee became a controversial figure in 2017 when he publicly sold all his LTC at the market peak and returned to Coinbase — yet the Litecoin community continued independent development.
Key Differences from Bitcoin
| Feature | Bitcoin (BTC) | Litecoin (LTC) |
|---|---|---|
| Block time | ~10 minutes | ~2.5 minutes |
| Maximum supply | 21 million | 84 million |
| Mining algorithm | SHA-256 | Scrypt |
| Halving cycle | 210,000 blocks | 840,000 blocks |
| Transaction speed | Slower | 4× faster confirmations |
Scrypt was initially chosen to resist ASIC mining; however, Scrypt ASICs eventually emerged and today Litecoin mining is largely ASIC-based.
MimbleWimble and Privacy (MWEB)
The MimbleWimble Extension Blocks (MWEB) upgrade, activated in May 2022, added an optional privacy layer to Litecoin. In MWEB transactions, the sender, recipient, and amount can all be hidden; this feature is opt-in — standard LTC transactions remain fully transparent.

Halving and Supply Structure
Litecoin's miner reward halves every 840,000 blocks (approximately every 4 years). The most recent halving occurred in August 2023, reducing the block reward from 12.5 LTC to 6.25 LTC. Total supply is hard-capped at 84 million LTC; the vast majority has already been mined into circulation.
Use Cases and Ecosystem
Thanks to fast confirmation times and low transaction fees, Litecoin holds a strong position as a payment medium. PayPal and several payment processors accept Litecoin. That said, the rise of the Bitcoin Lightning Network and the dominance of stablecoins in payments infrastructure has increased competitive pressure on Litecoin.
COINOTAG Perspective
Litecoin is one of the rare blockchains that has maintained operational functionality for more than 14 years without ever suffering a serious security breach. The MimbleWimble upgrade added technical diversity; however, it has no DeFi, NFT, or smart contract ecosystem. For investors, Litecoin largely behaves as a Bitcoin-correlated asset; creating an independent catalyst would require new adoption in the payments or privacy space.
Frequently Asked Questions
What is Litecoin (LTC)?
Litecoin is a cryptocurrency forked from Bitcoin in 2011 by Charlie Lee, featuring a 2.5-minute block time and a maximum supply of 84 million LTC. With the Scrypt mining algorithm and optional MWEB privacy layer, it is positioned as a faster, cheaper payment-focused alternative to Bitcoin.
What is the key difference between Litecoin and Bitcoin?
Litecoin's block time is 2.5 minutes (vs. Bitcoin's 10), its maximum supply is 84 million LTC (vs. 21 million), and its mining algorithm is Scrypt (vs. SHA-256). These differences make Litecoin better suited for fast transaction confirmations; however, Bitcoin's security network and adoption are far larger.
What is Litecoin's MimbleWimble (MWEB)?
MimbleWimble Extension Blocks (MWEB) is an optional privacy layer added to Litecoin in May 2022. In MWEB transactions, sender, recipient, and amount can all be hidden. The feature is opt-in — standard LTC transactions remain fully transparent.
When does Litecoin halving occur?
Litecoin's miner reward halves every 840,000 blocks (approximately every 4 years). The most recent halving was in August 2023, dropping the block reward from 12.5 LTC to 6.25 LTC. Halvings continue until the maximum supply of 84 million LTC is reached.
