A fundamental concept within Tornado Cash is the “anonymity set.” This refers to the number of other deposits in the pool that your transaction is mixed with. Essentially, a larger pool with more users provides a higher anonymity set, making it statistically harder for outside observers to link your deposit to your withdrawal. Choosing pools with significant activity enhances your privacy. The Tornado Cash guide explains how to evaluate pool sizes and select the optimal one for your needs, ensuring you maximize your financial privacy on the blockchain.
