Abstract NEBLO, a Nearly BLind Overlay, is a structured overlay network in which the use of imprecise routing tables, whose size and extent are severely constrained, yields a better privacy (aka ``anonymity'') to information requestors as well as providers, while keeping the length of routing paths within reasonable limits. Fingers in routing tables are imprecise, and the amount of approximation for a finger increases proportionally with the finger distance. This keeps routing paths within a logarithmic length, while making it impossible for a ``small'' coalition of malicious peers to correlate overlay addresses to hosts for censorship or auditing purposes.
