Riding the Hogwarts Express: An Empirical Analysis of Litecoin’s MWEB Adoption and Usage Patterns
conference paper
We present an analysis of Litecoin’s MimbleWimble Extension Block (MWEB), analysing 3.5 years of on-chain data from May 2022 through November 2025. Using transaction-level data from both transparent Litecoin and the MWEB protocol extension, we quantify adoption patterns, privacy set evolution, and user activity within this optional privacy mechanism. Our analysis reveals a baseline experimentation phase (2022–2023) followed by accelerated adoption from mid- 2024, yielding 10× growth in MWEB transaction volumes and sustained net accumulation reaching 350,000 litecoins in the privacy set. Kernel counts substantially exceeding combined peg-in/peg-out transactions indicate significant activity occurring entirely within the privacy set. Spend latency patterns show diverse usage suggesting mixing behaviour as well as longer-term private storage. Additional behavioural patterns indicate genuine human-driven usage rather than synthetic activity. These findings demonstrate that optional privacy through a protocol extension like MWEB can achieve meaningful adoption within an established cryptocurrency, offering implications for privacy-preserving blockchain design and regulatory discourse.
