Which canonical address is a legitimate address that nobody can claim?
Probably this address would be pretty acceptable - 1111111111111111111114oLvT2. It has a RIPEMD-160 hash of 0000000000000000000000000000000000000000.
The address 1FYMZEHnszCHKTBdFZ2DLrUuk3dGwYKQxh is a valid address made from an invalid public key which certainly qualifies as an effective /dev/null
It seems that the address was created by a bug in one particular wallet software.
By the way, don't burn money, it is the epitome of the old saying, "A fool and his money are soon parted."
Invalid public key was spent! How was this possible? (it wasn't, actually)
The funds of the address
16QaFeudRUt8NYy2yzjm3BMvG4xBbAsBFM can't be spent. Why? What makes it different from other addresses?
The private key is zero. ECDSA private keys must be greater than zero. If not, funds of that address can't be spend.
