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.
