What is Litecoin (LTC)? The Bitcoin alternative

Litecoin is one of the oldest projects in crypto. Founded in 2011 by Charlie Lee, a former Google employee, it was created as a “lighter” alternative to Bitcoin.

While it shares many similarities with Bitcoin, its main differences lie in:

1. The replacement of the SHA-256 hash algorithm used in Bitcoin with the Scrypt model
2. A reduction in block processing time from 10 (Bitcoin) to 2.5 minutes
3. An increase in the total number of coins (21 million for Bitcoin) to 84 million, resulting in a blockchain with:

• Lower transaction fees
• Faster transaction confirmation
• Lower barrier to entry for mining – at least at the early days of the project…

History of Litecoin

Charlie Lee often described Litecoin as “digital silver,” in contrast to Bitcoin, which he called “digital gold.” This metaphor conveyed a clear proposal: while Bitcoin represented a reserve currency, with higher transaction costs, strict scarcity, and mining dominated by large industrial structures, Litecoin sought to be the more accessible and agile alternative — a cryptocurrency geared towards everyday use, with faster and cheaper transactions.

Litecoin was therefore born as a popular alternative to Bitcoin, just as gold has been for the elites and silver for the people. To this end, Lee made important technical choices: he replaced the SHA-256 hash algorithm used by Bitcoin with Scrypt, which was more memory-dependent and, at the time, resistant to mining by ASICs. This made it possible to mine Litecoin using CPUs and GPUs, thus democratizing access and attempting to preserve the decentralized spirit that had marked the early years of Bitcoin.

However, from 2014 onwards, the industry responded with ASICs adapted to Scrypt, and the Litecoin mining process also became centralized — albeit on a smaller scale.

In addition to the mining algorithm, other structural changes reinforced Litecoin's reputation as “digital silver.” Block time was reduced to 2.5 minutes (compared to Bitcoin's 10 minutes), resulting in faster transaction confirmations and generally lower costs. The maximum number of coins has also been increased: 84 million LTC, exactly four times the supply of Bitcoin, reinforcing the idea of a more abundant and tradable asset.

Over time, Litecoin established itself as one of the most stable and enduring cryptocurrencies on the market, regularly ranking among the top 20 projects by market value.

More than that, it has become an experimental hub for innovations in the Bitcoin ecosystem. It pioneered the adoption of Segregated Witness (SegWit) in 2017, a scalability improvement that would later be implemented in Bitcoin. It also served as a testing ground for the Lightning Network, a second-layer instant payment solution, and in 2022 introduced the MimbleWimble Extension Block (MWEB), offering an optional layer of privacy to transactions — a feature missing from Bitcoin.
