66## TODO
67- When a peer connects to the network, sends his last Block, and receives the new Blocks from this last Block --> DONE with REST petitions, maybe is better with tcp conn
68- Delete the peer from the peers list when the connection is closed --> DONE
69- REST:
70    - endpoint to get if the address is in the blockchain (to verify users)
71- parameters Date or LastUpdate on the structs needs to be updated values
72- implement rsa encryption between peers
73- store blockchain in a .data file
