Unleashing the Flood: Stress-Testing the Monero Network
2025-06-21 , Main Stage

On 2022-08-12, Monero's network was stress-tested with ~50,000 transactions and under $1,000 in fees in 24 hours, triggering "dynamic block sizing" for the first time, and highlighting performance constraints. Under peak load, few nodes crashed, and average confirmation times rose from about 2min to roughly 30 minutes (≈ 15 blocks). Services like CakeWallet - then running on 'default low-priority fees' - also experienced multi-hour slowdowns, with some users reporting 3hr waiting times (https://x.com/cakewallet/status/1558094085642194945). These results expose concrete performance constraints in fee estimation, mining rules and node stability, and point to targeted improvements for optimized tx-pool management and adaptive fee algorithms - to bolster Monero’s resilience. The findings underscore the need for ongoing, high-intensity testing to ensure Monero can more efficiently handle unexpected traffic spikes without sacrificing privacy or decentralization.
