Accepts works with entropy source.

[AnFunctionArray]

So I wanted to implement some randomness into the standard randomx algo and was surprised to find that I was able to skip the whole algo with some incredible hash speeds.

it's something like (in xmrig randomx.cpp):

    void randomx_calculate_hash_next(randomx_vm* machine, uint64_t (&tempHash)[8], const void* nextInput, size_t nextInputSize, void* output) {
        PROFILE_SCOPE(RandomX_hash);

        /*machine->resetRoundingMode();
        for (uint32_t chain = 0; chain < RandomX_CurrentConfig.ProgramCount - 1; ++chain) {
            machine->run(&tempHash);
            rx_blake2b_wrapper::run(tempHash, sizeof(tempHash), machine->getRegisterFile(), sizeof(randomx::RegisterFile));
        }
        machine->run(&tempHash);*/

        getentropy(tempHash, sizeof tempHash);

        // Finish current hash and fill the scratchpad for the next hash at the same time
        // rx_blake2b_wrapper::run(tempHash, sizeof(tempHash), nextInput, nextInputSize);
        machine->hashAndFill(output, tempHash);
    }

But if i connect to minexmr.com it says invalid share straight up.

Don't know if this exploit.

it says invalid share straight up Well, of course. It's not an exploit.

That would be on minexmr - on p2pool it accepts it. But whatever not my issue - just reporting.

[SChernykh]

It accepts it because it uses the exact same code to check this "share". But other p2pool nodes will reject your shares and ban your node.
