I tried to find in the code puzzles from Satoshi Nakamoto and I may have found them.

I don't think you have. I obviously don't know for sure, but let me explain why I think these numbers are (1) not a secret message and (2) why this does not matter.

How do you think the meaning of these symbols? https://github.com/bitcoin/bitcoin/blob/master/src/chainparams.cpp#L110-L113

These 4 bytes are known as the network magic, and are common practice in binary formats and protocols, as a means for making sure you're talking to a peer that talks the same protocol.

The original code by Bitcoin's creator even had a comment that explains the choice of these values: // The message start string is designed to be unlikely to occur in normal data. // The characters are rarely used upper ascii, not valid as UTF-8, and produce // a large 4-byte int at any alignment. static const char pchMessageStart[4] = { 0xf9, 0xbe, 0xb4, 0xd9 };

So they're just 4 arbitrary bytes chosen in such a way that they're unlikely to occur in text or as an encoding of common integers in typical protocols.

Satoshi Nakamoto was involved in cryptography, and I believe that as a true lover of cryptography it is encrypted message for fans to guess the puzzle as we are.

I think 4 bytes is way too little to encode any meaningful message.

Furthermore, it does not matter. While Bitcoin's creator came up with all the right pieces to make a distributed digital currency work in practice, its largest innovation compared to previous attempts is the lack of trusted parties. No need to trust a central bank, or trust the people you're transacting with, or trust who came up with the idea.

I'm sure you can come up with many patterns that fit whatever 4 bytes, if you really want to. That doesn't mean there is a meaning.
