Litecoin (LTC) was created to improve upon Bitcoin, offering three key differences. First, the Litecoin network processes blocks every 2.5 minutes (vs. Bitcoin’s 10 minutes), enabling faster transaction confirmations. Second, Litecoin’s total supply cap is 84 million coins—four times Bitcoin’s 21 million. Third, Litecoin uses the scrypt algorithm in its proof-of-work (PoW), making mining more accessible on consumer hardware. — Adapted from Wikipedia
TL;DR: 👉 Litecoin employs the Scrypt hash algorithm, which is computationally lighter than Bitcoin’s SHA-256. This results in faster block times, lower hardware requirements for miners, and a higher total coin supply.
Mining and Hash Rates Explained
Cryptocurrency mining involves repeatedly calculating hash values that meet specific conditions (difficulty targets). A hash looks like this:
000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26fMiners compete to solve these hashes first. The winner receives block rewards and transaction fees, and the cycle repeats. The hash difficulty adjusts dynamically to maintain consistent block times, giving rise to hash rate metrics.
Hash Rate Units:
- kH/s: 1,000 hashes per second
- MH/s: 1,000,000 hashes per second
- GH/s: 1 billion hashes per second
- TH/s: 1 trillion hashes per second
- PH/s: 1 quadrillion hashes per second
- EH/s: 1 quintillion hashes per second
Higher hash rates mean greater difficulty, requiring more powerful hardware. For perspective:
- Bitcoin’s network hash rate: ~8 EH/s
- Litecoin’s network hash rate: ~25 TH/s (two orders of magnitude lower)
Top Mining Hardware:
- Litecoin: AMD HD7990 GPU (1.5 MH/s)
- Bitcoin: AntMiner S9 ASIC (14 TH/s)
Despite regulatory pressures in 2021, Bitcoin’s hash rate remained stable, while Litecoin’s gradually increased.
SHA-256 vs. Scrypt: Key Differences
| Feature | SHA-256 (Bitcoin) | Scrypt (Litecoin) |
|---|---|---|
| Speed | Slower (10-minute blocks) | Faster (2.5-minute blocks) |
| Energy Use | High (ASIC-dependent) | Lower (GPU-friendly) |
| Memory | Not memory-intensive | Memory-hard (resists ASIC dominance) |
| Security | Robust due to computational weight | Relies on faster block confirmations |
Debates:
- SHA-256 proponents argue its slower processing enhances security.
- Scrypt supporters claim Litecoin’s faster confirmations make it equally secure under PoW.
