It is usually argued that the hash of the latest block is not a good source of randomness because miners can manipulate that outcome.
I was thinking in the case of Euromillions if it would seem secure enough to use the hash of the hashes of latest 1000 blocks.
To further make it more difficult to manipulate all hashes to be hashed would be ordered according to their position in terms natural counting ordering, that is, the lowest hash would come first in the concatenation.
Further, each hash would be hashed with its Unix timestamp, before entering the special order concatenation.
I think this would be an ultra safe extraction for a game like euromillions.
What do you think? I think it is quite unthinkable to manipulate the hashes of 1000 blocks even more if they are further hashed with their timestamp and put in a specific place of the concatenation to be hashed.
What do you think?

{ Imagine a sequence of bits generated from the first decimal place of the square roots of whole integers that are irrational numbers. If the decimal falls between 0 and 5, it's considered bit 0, and if it falls between 5 and 10, it's considered bit 1. This sequence from a simple integer count of contiguous irrationals and their logical decimal expansion of the first decimal place is called the 'main irrational stream.' Our goal is to design a physical and optical computing system system that can detect when this stream starts matching a specific pattern of a given size of bits. bitcointalk.org/index.php?topic=166760.0 } Satoshi did use a friend class in C++ and put a comment on the code saying: "This is why people hate C++".

Technically the latest block finder would still be able to manipulate the hash anyway.
