2015-01-15 - a transaction was created in blockchain (included in block 339085) containing a transfer transaction for 256 different Bitcoin addresses: https://blockchain.info/tx/08389f34c98c606322740c0be6a7125d9860bb8d5cb182c02f98461e5fa6cd15
2017-07-11 - funds from addresses 161-256 were moved to the same number of addresses of the lower range - thus increasing the amount of funds on them. This takes place in block 475240: https://www.blockchain.com/btc/tx/5d45587cfd1d5b0fb826805541da7d94c61fe432259e68ee26f4a04544384164
2019-05-31 - the creator of the "puzzles" creates outgoing transactions with the value of 1satoshi for addresses #65, #70, #75, #80, #85, #90, #95, #100, #105, #110, #115 , #120, #125, #130, #135, #140, #145, #150, #155, #160 with the aim of probably comparing the difficulty of finding a private key for the address from which such a transaction was carried out, and one that There is no transaction.
2023-04-16 - The creator of the challenge paid rounded amounts of BTC to the remaining unguessed addresses - thus increasing the value of the prizes by a total of over 900 BTC. From this moment, for example - the reward value for address 66 is not 0.66BTC but 6.6BTC

First output: take random number from 20 upto 21-1, use it as private key
Second output: take random number from 21 upto 22-1, use it as private key
Third output: take random number from 22 upto 23-1, use it as private key
Second output: take random number from 21 upto 22-1, use it as private key
Third output: take random number from 22 upto 23-1, use it as private key
The outputs relate to transactions from 2015 in which the transaction was performed for all 256 addresses.
