01:11:28 <m-relay> <d​ark_sky:monero.social> Is anyone aware of any rust project using RandomX, bindings , etc... ?

09:52:22 <parazyd> Hey I'm doing some experiments with a regtest and solomining with my own proxy
09:52:50 <parazyd> Monerod gives me a difficulty of "2568" and when I proxy the getblocktemplate to xmrig, I also see diff "2568" in xmrig
09:53:17 <parazyd> However upon submitting a block, monerod logs: does not have enough proof of work: <hash> at height 2000001, unexpected difficulty: 2568
09:53:26 <parazyd> And the block verification fails
09:53:37 <parazyd> Anyone got an idea why this is happening?
10:06:08 <parazyd> Perhaps relevant, I'm removing `extra_nonce` from xmrig's getblocktemplate request and replacing it with `reserve_size`
10:20:55 <sech1> if you modify xmrig's request, maybe you get a response that xmrig doesn't expect, and it computes wrong hashes.
10:28:39 <parazyd> sech1: I am not modifying the difficulty though, and monerod says that it fails block verification with "unexpected difficulty". Could that error be misleading?
10:29:32 <parazyd> It's xmrig in daemon mode. What's the assumption in xmrig with its `extra_nonce` that it's sending as part of the getblocktemplate request?
10:30:12 <parazyd> I doubt it should be trying to include that in the mined block in any way, since it's not building a block on its own, rather should be mining the one that it gets as a getblocktemplate response
10:32:02 <parazyd> My proxy is modifying blocktemplate_blob and then also updating the blockhashing_blob
10:33:31 <sech1> Maybe you calculate blockhashing_blob wrong
10:33:42 <sech1> xmrig expects extra_nonce to be 8 bytes
10:34:02 <parazyd> I'm using this: https://docs.rs/monero/latest/monero/blockdata/block/struct.Block.html#method.serialize_hashable
10:34:55 <sech1> Try to check if you get the same hashing blob if you don't modify the template
10:35:09 <parazyd> Okay 
10:40:28 <parazyd> hm interesting, the Rust code prepends a byte
10:40:28 <parazyd> Possibly VarInt
10:43:56 <parazyd> https://github.com/monero-rs/monero-rs/issues/188
10:43:58 <parazyd> :)
10:55:35 <sech1> monero-rs has a lot of bugs, especially in the rarely used parts of the code
10:56:07 <parazyd> Well it's free software, so we can fix it :)
11:02:38 <parazyd> sech1: Thanks for the pointer, it works with this change: https://github.com/monero-rs/monero-rs/pull/194/files
11:02:46 <parazyd> (Removing the prepended VarInt)
