Conversion

At this phase Arena converts the hash values into draw numbers. Since the hash numbers are random and unpredictable, the final number list will also be such a random list.

Step 1

Take the block details and concatenate them as Block's hash + Previous block's hash + Block's Nonce (or StateRoot if Nonce is 0) without the leading "0x" string.

Result: 75d951f043d78c7e8b4ef7894f944ae11fd1071292e30a76d2454997c82782b4 1ec6c1900e558bf42a9311e6243ef196545a2a1cf5ef488a6144515457281bac 25747bd2d612019d6a0beb9ba3236751b22af548a78387f577e070f3e031b97d

Step 2

Divide this long string by 2 units

75 d9 51 f0 43 d7 8c 7e 8b 4e f7 89 4f 94 4a e1 1f d1 07 12 92 e3 0a 76 d2 45 49 97 c8 27 82 b4 1e c6 c1 90 0e 55 8b f4 2a 93 11 e6 24 3e f1 96 54 5a 2a 1c f5 ef 48 8a 61 44 51 54 57 28 1b ac 25 74 7b d2 d6 12 01 9d 6a 0b eb 9b a3 23 67 51 b2 2a f5 48 a7 83 87 f5 77 e0 70 f3 e0 31 b9 7d

Step 3

Convert the hexadecimal numbers to decimal ones (eg. 75[hex] => 7 * 16 + 5 = 117[decimal]).

Step 4

Search for duplicates and drop every other than the first occurrence
