Bitpeer is an experimental Bitcoin relay server. Its event-driven architecture makes it extremely fast, and it was designed to be very lightweight.

The target memory limit is 10MB for handling 1000 peers, plus 15 for the block indexes.

• Transaction relaying using a small in-memory pool
• Block relaying using disk-based block storage
• Handling several thousands of peers, if the network allows it
• Extremely lightweight (below 25MB memory usage up to 1000 peers)
• Extremely fast (using sendfile support and a lot of caching)
• Address relaying (getaddr coming soon)

./bitpeer <listen_port> <public_ip[:port]> -n <seed_addr[:port]>

./bitpeer 8333 1.2.3.4 -n 5.6.7.8:8333

When building from git:

autoreconf -i
./configure
make

When building from a tarball:

./configure
make

The code currently only requires the libevent2 and openssl libraries. Kernel support for IPv4 to IPv6 mapping is also required.
