and where i should find the .tx file ? because i tried to do it but bittrex said that the file format is wrong
Blade Doyle
@bladedoyle
You probably need to use wallet version 3.x to transact with exchanges....im sure they have not updated to 4 yet
Maksim Golota
@babrnyashka_twitter

hey
why did the hashrate for AR29 take a *0.1 hit ?
Blade Doyle
@bladedoyle
Hi @hivemall Its a combination of things. Grins POW algorithm is designed to change over the first few (2) years and become more "difficult". The increased time to create a graph (hash) means fewer are created. That accounts for a lot of the hashrate decline. Another factor is profitability. Over time grin has dropped in value so it can support fewer miners.
Also the C29 algorithm is changed every 6 months, and the most recent change cut the graph rate in half:

@bladedoyle
The graph you link to is missing C32 which is now grins dominant POW
Here are a few fun graphs:

how to set Cuckoo Size to 32 on 4.0.0 node ?
Blade Doyle
@bladedoyle
You mean when mining against the built-in stratum server?
You dont need to change any settings. The stratum server accepts all valid sizes. the Cuckoo Size: 31 on the nodes Mining tab is meaningless - ignore it.
You can set the size in the miners config

@coolman_kurt_twitter
Thanks @Whataloser I noticed one instance also in the github rfc page. @quentinlesceller has been able to correct it to the appropriate site grin.mw. Was it at this place (in the rfc page) that you noticed it?
We are mainly on keybase now, if you have access to it. #grincoin

@hivemall

@hivemall
can i view wallet balances in grin? if send from exchange to local how to verify receive without node conneted on https://github.com/mimblewimble/docs/wiki/Wallet-User-Guide#node-address
hivemall
@hivemall
looking for some to quickly get stuff to and out from yet longterm, no fullnode
Blade Doyle
@bladedoyle
You need a node to verify the transaction is posted to the blockchain. I guess you could use data from an explorer to verify the output is on the chain. Another option is to use a public node such as https://grinnode.live/

@hivemall
mmh, so no paperwallet thingy, dear thats missing!
exmaple https://pyrus.ubiqsmart.com/ super simple and good, can we please have that
Whataloser

anyone else having trouble verifying the shasum for grin-wallet-v4.0.0-macos.tar.gz?

The shasum file:

SHA256(/Users/runner/runners/2.171.1/work/1/a/grin-wallet-v4.0.0-macos.tar.gz)= f18615b8f2d49bf444fd0f413a322984e5fb36147cc0031f637b86ee17d82d15

however:

$ wget https://github.com/mimblewimble/grin/releases/download/v4.0.0/grin-v4.0.0-macos.tar.gz
$ shasum -a 256 grin-v4.0.0-macos.tar.gz

Anyone else have MXC exchange tell them that they won'twithdraw??
Blade Doyle
@bladedoyle
I’m not familiar with Mxc specifically but many exchanges have temporarily halted grin deposits and withdraw due to the recent 51% attack. They should open again soon but with longer confirmation times.
