Arbitrum vs Litecoin FAQ
- What is Arbitrum?
- Arbitrum is an optimistic rollup on Ethereum built by Offchain Labs. Mainnet launched August 2021 as Arbitrum One; a second chain — Arbitrum Nova — targets gaming/social with AnyTrust data availability. By early 2026 it is consistently the largest L2 by TVL, rivalled only by Base.
- What does "optimistic rollup" mean?
- Transactions posted to L1 are assumed valid by default. A 7-day challenge window lets any watcher submit a fraud proof to revert fraudulent batches. The sequencer (currently centralised, operated by Offchain Labs) orders transactions; decentralising it is on the roadmap. Security ultimately inherits from Ethereum.
- What is Litecoin?
- Litecoin (LTC) is a proof-of-work cryptocurrency launched in October 2011 by Charlie Lee, a fork of Bitcoin with shorter block times (2.5 min vs 10) and the Scrypt hashing algorithm. It targets a "silver to Bitcoin's gold" positioning.
- What is MimbleWimble on Litecoin?
- Activated in May 2022, the MimbleWimble Extension Blocks (MWEB) let users opt in to confidential transactions on Litecoin. It's a side-chain style upgrade — hash-linked to the main chain but with hidden amounts for those who choose to use it.
