This format also is used in eMule, in the SafePeer Vuze plugin, ProtoWall, KTorrent, and Transmission. Unfortunately this meant that lists became very large and cost a lot of bandwidth to distribute, heralding the construction of the smaller binary formats. The original format for PeerGuardian version 1.x was a simple plaintext format. The recent adoption of this format made it the least compatible one. This format uses 7z compression for additional size reduction.

P2B Version 3 – The newest version of the P2B format, this is currently supported only on the latest version of the Windows version of PeerGuardian 2.

It is equivalent to the first version of the P2B format, but instead uses UTF-8 to store names.

P2B Version 2 – The most widely used format, this is supported among a number of applications, including eMule and the Linux version of PeerGuardian.

Lists are no longer produced in this format.

P2B Version 1 – This format was used only in the earliest releases of PeerGuardian 2.

The binary formats (known as P2B) were created at the release of the first beta version of PeerGuardian 2, in order to create the smallest possible blocklist. The blacklist is stored in a number of different formats: Support for both Windows Vista and IPv6 were in release candidate phase as of May 2009.

As with most other desktop firewall software for Windows, Version 2.0 is installed as a kernel-level filter in Windows 2000 and later, giving the application direct access to the Windows networking stack and improving performance. Speed and resource inefficiencies were fixed by re-designing and re-coding Version 2.0 in C++ to consume less processing power and memory.

The installation procedure was also simplified, no longer requiring a system restart and driver installation. Version 2 enabled support for more protocols (TCP, UDP, ICMP, etc.), multiple block lists, and automatic updates. The development of version 2.0 was led by Cory Nelson, and aimed to resolve many of the shortcomings of Version 1.

The original PeerGuardian (1.0) was programmed in Visual Basic and quickly became popular among P2P users despite blocking only the common TCP protocol and being known for high RAM and CPU usage when connected to P2P networks. The first public version was released in 2003, at a time when the music industry started to sue individual file sharing users (a change from its previous stance that it would not target consumers with copyright infringement lawsuits). Development on PeerGuardian started in late 2002, led by programmer Tim Leonard.
