I have never seen these errors. Is it safe to use cli-wallet to transfer funds? Should I be concerned? Using Monero 'Wolfram Warptangent' (v0.10.0.0-release) and macOS Sierra 10.12 (16A323).

  • Please add some more information, e.g., which version are you on (you can check this by typing version into the daemon) and which OS are you using?

Someone is running a node that supports fluffy blocks and running on mainnet. In handshake, it's sending a request to find out if you support fluffy blocks, but current release nodes don't know about that command.

    I didn't know that Monero was so close to have thin blocks implemented, I just learned about it and your work today. Thank you for making that happen!

    I'm a big fan of the Monero project, and the community as well, so I wanted to contribute in whatever way I could. The developers were extremely helpful, and I would encourage anyone on the fence to just dive in and start contributing. Every little bit helps.

    Nothing. It is not harmful to you.

  • revler1082, I'd add this to your answer too, since you didn't exactly reply to the "what do I do" side of the question.
