Was ist Private key?
The secret number that authorises spending from an address. Whoever holds it controls the coins, unconditionally.
A private key is a 256-bit number. The corresponding public key and address are derived from it one-way, so publishing an address reveals nothing about the key.
There is no recovery mechanism. This is the whole point — nobody can seize or reverse what only you can authorise — and the whole risk.
