Litecoin

Litecoin receives a B- risk grade (31/100) from Hindenrank, where lower scores indicate lower risk. Moderate-low risk — 12+ years of L1 operation with a clean core chain record, Bitcoin-derived design, and SEC digital commodity status, offset by three MWEB extension block incidents and ongoing patch cadence. Litecoin is one of the earliest Bitcoin alternatives, launched in 2011 with a Scrypt-based proof-of-work algorithm and 2.5-minute block times for faster transaction confirmation. With a market cap of approximately $4.2 billion, LTC ranks among the top 25 cryptocurrencies and received an SEC digital commodity classification in 2026. Its B- grade reflects 12+ years of continuous L1 operation, a Bitcoin-derived design, and broad institutional recognition — offset by three MWEB security incidents in 2025-2026 (including a 13-block chain reorganization in April 2026) and ongoing extension block hardening (five patch releases in eight weeks as of May 2026).

The key risks identified for Litecoin are: (1) Litecoin's block rewards halve every four years (next halving July 2027, reducing to 3.125 LTC per block). With low transaction fees (~$14K/30d protocol revenue), miner revenue depends heavily on LTC price to sustain network security. Hashrate has declined from its 2025 peak of 2.7 PH/s to ~2.3 PH/s. (2) MWEB has produced three security incidents: a privacy bug patched in May 2025; a March 2026 consensus exploit (85,034 LTC fake pegout, ~84,184 LTC recovered via emergency developer/miner coordination, attacker kept 850 LTC); and an April 2026 reorg exploit (13-block chain reorganization, ~$600K in double-spend losses against cross-chain swap protocols). Litecoin Core v0.21.5.5 (May 7, 2026) is the fifth patch in eight weeks. The core UTXO chain has not been directly compromised, but the MWEB extension block subsystem has not fully stabilized. (3) While Litecoin uses Scrypt mining (separate from Bitcoin's SHA-256 ecosystem), ASIC manufacturing for Scrypt is concentrated among fewer producers, creating potential supply chain risks for mining hardware diversity.

Litecoin scores 31/100 across eight risk dimensions: Mechanism Novelty: 0/15, Interaction Severity: 2/20, Oracle Surface: 0/10, Documentation Gaps: 3/10, Track Record: 12/15, Scale Exposure: 7/10, Regulatory Risk: 1/10, Vitality Risk: 6/10. The highest risk area is Track Record at 12/15.

Among 56 rated L1 protocols on Hindenrank, Litecoin ranks #23 by safety (lowest risk score = safest). Its 31/100 risk score and B- grade place it in the middle tier of L1 protocols.

Litecoin scores 12/15 on the Track Record risk dimension, indicating some history of security incidents or exploits. Higher scores reflect more severe or frequent incidents. Review the full risk report for details.
