I recently read topic
https://bitcointalksearch.org/topic/bitcoin-source-from-november-2008-382374 and I wonder how exactly that prenet genesis transaction looked like. After some digging I came up with this:
decoderawtransaction 01000000010000000000000000000000000000000000000000000000000000000000000000ffffffff0504695dbf0effffffff01102700000000000044ab4104d451b0d7e567c615719a630b9f44632a0f34f5e7101f9942fe0b39996151cef10a809c443df2fab7cd7e58a3538cd8afd08ccfaa49b637de4b1b383f088ad131ac00000000
{
"txid": "25c61a7089aa96318088bcccfbc12064a18166105c20c237836704611254d2da",

}
}
]
}
Of course I know that transaction version was not present here (in the same way as in the block hash there was no version) and I can calculate sha256 of any data, but still, that transaction should hash into 769a5e93fac273fd825da42d39ead975b5d712b2d50953f35a4fdebdec8083e3. I tried using different values for OP_CODESEPARATOR and OP_CHECKSIG than 0xab and 0xac, but still no match. I tried different endianness in 32-bit and 256-bit values, but still no luck.
The only success so far was hashing the prenet genesis block:
prenetGenesis=0000000000000000000000000000000000000000000000000000000000000000e38380ecbdde4f5af35309d5b212d7b575d9ea392da45d82fd73c2fa935e9a76a00bc84814000000bb290200
prenetGenesisHash=7ae24cfad8adbe66ab2224a4f7269694fa2fa9aa157b1e44c608bd386fb6160b
prenetGenesisDoubleHash=46a6fa0cbc6e41aaebb6916c55013a0ad66b11e91d1d977ed627135db1060000
prenetGenesisFinalHash=000006b15d1327d67e971d1de9116bd60a3a01556c91b6ebaa416ebc0cfaa646
Is that lost in the past or is it possible to reconstruct that transaction as it was in prenet?
