are there settings/compile options that make it possible to run a node with under 4G ram, or is that a minimum? OOM killer gets me if I run with less:(

It should be more than enough unless you're syncing historical blocks. If that's what you're doing, check --db-sync-mode, tell it to sync more often - it'll be slower though.

Also check monerod --help for interesting things. Like... amount of memory to download new blocks before they're added. Forget the name.

Fewer peers might also help.

it is syncing, does it use less when it's up to date then?

Yes.

Syncing means downloading lots of blocks, placing them in a queue, then adding them, typically 20 at a time. Plus syncing the DB every, er, lots.

When you're just keeping up with new blocks, add a block at a time, sync after each block.

Syncing more often while syncing historical blcks will kill performance, which is already not great.

But play with it, and see what you can get away with.

Or just keep > 4 GB till you're synced if you can, then lower.

yeah, I think I'll do that, it's over halfway so hopefully done in a few hours

would've been done already if I'd given the VM enough ram from the start :D

--db-sync-mode default is fast:async:250000000bytes, so that's presumably 250Mb I could lose some of

FWIW sync speed is much faster at start for various reasons. Mostly tx volume being a trickle for the first few years.

But the last few thousand blocks are much slower as more is checked.

does the database size on disk grow faster towards the end? it's at 54% using 20G disk for a pruned node, which would mean ~40Gb total *if* it grows at the same rate, but I was expecing more like 70G for a pruned node

I guess if the first blocks are smaller that'd explain why it syncs a good way in before the OOM killer gets it

afaict not setting --block-sync-size means it'll do 20 blocks at a time, but I don't know how big a block is so... :)

A pruned DB is 60 ot 65 GB or so I think.

Most early blocks are empty. Most late blocks are not. But IIRC adds are made 200 blocks at once for the early chain.

ah, is that what BLOCKS_SYNCHRONIZING_DEFAULT_COUNT_PRE_V4 is

why did empty blocks get added? (sorry if this is an idiot question)

To keep track of difficulty.

And if you add a rule that says you can't add empty blocks, miners will start adding their own dummy tx, so no gain, and a loss from spam.

I never did quite figure out difficulty, I should probably re-read the original bitcoin paper again but the math was over my head the last time I tried :/

Hey, what is the reason here that xmrig closes the connection after receiving a job? termbin.com/8e5d

Context, I'm trying to write a mining proxy

"target":"0x2" doesn't look right

and "id" field is missing in the response

sech1: The stratum doc says it's a notification, so there should be no ID: github.com/xmrig/xmrig-proxy/blob/master/doc/STRATUM.md#job

The same disconnect happens when I use for example "b88d0600" for "target"

Try to connect to xmrig-proxy and find the difference in what you send and what xmrig-proxy sends in response to "login" message

oh, you definitely forgot to send "seed_hash" in the job. RandomX requires it

and "height"

I recommend to check what P2Pool replies to login message: github.com/SChernykh/p2pool/blob/ma…/stratum_server.cpp#L309C74-L309C74

There's quite a different in what it sends

first of all, it's not "params" but "result"

So it means that STRATUM.md is outdated

absolutely

Thanks for the link

actually, you should've looked at github.com/xmrig/xmrig-proxy/blob/m…oc/STRATUM.md#example-success-reply

with the addition of "algo", "seed_hash" and "height" fields

oh

Yeah missed that one

It's outdated because it doesn't mention "algo" extensions, but it's mostly accurate

Alright, will see where that gets me

sech1: It's getting me _somewhere_ now: termbin.com/25ji

I'm trying this just on a local-only monerod testnet node

AFAICT it means that seed_hash is invalid

What should it be on height 1 though?

Since getblocktemplate() gives me an empty string for seed_hash on height 1

RandomX was activated at later height.

1978433 for mainnet, 1308737 for testnet

ahhh

Hello, I'm forking cryptonote and am having difficulty with the gui wallet. I have the core compiled and working on ubuntu16 and win10, and the gui wallet working on ubuntu 16. But I am not able to get the gui wallet to compile on windows. I make the symbolic link and git submodule, and these are the commands I use to cmake and build:

cmake -G "Visual Studio 15 2017" -A Win32 .. -DBOOST_ROOT=B:/local/boost_1_55_0 -DBoost_ATOMIC_LIBRARY="B:\local\boost_1_55_00\libs\atomic" -DBoost_SYSTEM_LIBRARY="B:\local\boost_1_55_00\libs\system" -DBoost_FILESYSTEM_LIBRARY="B:\local\boost_1_55_00\libs\filesystem" -DBoost_THREAD_LIBRARY="B:\local\boost_1_55_00\libs\thread" -DBoost_DATE_TIME_LIBRARY="B:\local\boost_1_55_00\libs\date_time"

cmake\Qt5Widgets"

MSBuild CryptoNote.sln /p:Configuration=Release /p:Platform=Win32 /p:PlatformToolset=v140_xp /m

But the build fails with a function overload error:

if anyone has any help or suggestions for compiling the cryptonote wallet from github.com/cryptonotefoundation/cryptonotewallet on windows 10, then I would really appreciate it
