Looking for things to hack on?

Cleanups

• Remove our specific libsecp256k1 in secp256k1/ and use the installed one.

Minor improvements

• Make json_get_params fail if unknown parameters are specified by user.
• Print backtrace in log_crash
• When unpacking a packet, reject any with an unknown odd-numbered field as per BOLT #2.
• Limit total number of peers in new_peer, or at least in peer_connected_in.
• logging: add IO logging for peers.
• Add history RPC command which shows all prior commit txs.
• Improve getpeers to show status of peers when connecting, DNS lookups etc.
• Add pings to protocol
  • Timeout a peer if they don't respond in a given time (eg. 2 pings)

Testing:

• Add more unit tests in bitcoin/test and daemon/test
• Test more scenarios with daemon/test/test.sh, and split it up.
• Implement compile-time crypto-free mode
  • Implement canned conversation files for fuzz testing (eg AFL).
• Write canned input/output test cases for various conversations, and include them in a form suitable for other implementations to test.

Major improvements:

• (MAJOR) Implement onion
  • (MAJOR) Implement failure message encryption

Other

• Grep for other FIXMEs and fix one :)
• Look on https://github.com/ElementsProject/lightning/issues

Happy hacking!
