Re: Bitcoin puzzle transaction ~32 BTC prize to who solves it

If the public key is revealed it is still safe from bruteforce if the attacker don't know the range of bits to search for?

Of course.
Many blocks mined by Satoshi have txs with "pay to public key" script (P2PK) instead of "pay to public key hash" script (P2PKH, pay to address).

The public keys are known, but the btc are still there:

Hi

look at the date 2011-06-11 12:57:32
those where normally mined blocks that where normally spent back then.

unlike this one https://www.blockchain.com/it/btc/tx/2d05f0c9c3e1c226e63b5fac240137687544cf631cd616fd34fd188fc9020866 mined on 2009-01-11 08:00:25 when BTC was not worth a penny !

the first mined block on 2009-01-09 02:54:25 is still unspent https://www.blockchain.com/fr/btc/address/12c6DSiU4Rq3P4ZxziKxzrL5LmMBrzjrJX
