Anonymous network I2P 2.2.0 and C++ client i2pd 2.47.0 have been released. I2P is a multi-layer anonymous distributed network operating on top of the regular Internet, actively using end-to-end encryption to guarantee anonymity and isolation. The network is built in P2P mode and is formed thanks to the resources (bandwidth) provided by network users, which makes it possible to do without the use of centrally controlled servers (communications within the network are based on the use of encrypted unidirectional tunnels between the participant and peers).
On the I2P network, you can anonymously create websites and blogs, send instant messages and e-mails, exchange files, and organize P2P networks. To build and use anonymous networks for client-server (websites, chats) and P2P (file exchange, cryptocurrencies) applications, I2P clients are used. The basic I2P client is written in Java and can run on a wide range of platforms such as Windows, Linux, macOS, Solaris, etc. I2pd is an independent C++ implementation of the I2P client and is distributed under a modified BSD license.
The new release implements changes in the NetDB, Floodfill and Peer-Selection components aimed at maintaining the router's performance in the face of DDoS attacks. Added protection against attacks that manipulate the resending of previously intercepted encrypted packets to the Streaming subsystem. New search features have been added to i2psnark. Support for restricting incoming connections has been added to transports. Improved performance of block lists.
