Hi @wade-liwei I’m afk right now. Mind joining us on Keybase chat (it’s the official chat right now) and there are other people who might be able to help you
wade
@wade-liwei
Could you please share me the Keybase chat link ?

hi @wade-liwei sorry for the delay. Here is the link https://grin.mw/community

@wade-liwei

hello @quentinlesceller

could you give me example about how to use the func:

api := example.NewGrinServerApi("127.0.0.1:13413")

block, err := api.GetBlockByHeight(*blockHeight)
root@test-server:~/grin# ./queryBlock -blockHeight 379317
api.GetBlockByHeight(blockHeight: 379317 ) err: error during getJSON. Status code: 401

@bladedoyle
401 means unauthorized. I think you need to send basicauth with the request

Is there a dedicated list of peers i can use? my node is falling behind
johndavies24
@johndavies24
@cyrus19901_gitlab Ive been trying to report this for a while, not everyone seems to have the same experience
Rajveer Singh
@cyrus19901_gitlab
@johndavies24 i agree , not sure if its because of just bad peers in the config
johndavies24
@johndavies24
deleting peers has never solved it for me, i spun up a bunch of nodes and all my nodes behind my router (no port forwarding) work all the time, only my non-leeching nodes (one is a seed node) fail. This started started at one of the mid v2 versions

@zuhair-naqvi
Does grin need to run a full node to operate a wallet?
johndavies24
@johndavies24
doesnt "need" but would require configuration to work with a remote node. Only reputable grin wallet that I am aware of that works this way out of the box is the mobile ironbelly
Blade Doyle
@bladedoyle
@zuhair-naqvi the wallet can listen and receive coins (by http or slate file) without a node. However, the wallet needs to get blockchain info from a node to confirm the coins were actually received, and it needs a node to transmit any send transactions

Hey peeps, did work on Grin/BTC atomic swaps stop? I don't see any recent commits in the vault713/grinswap github repo

@knaccc
Ah, i just switched to keybase since that seems to be the new place people are, so closing this window...
jaspervdm
@jaspervdm
its not my focus at the moment
knaccc
@knaccc
@jaspervdm ah ok thanks for replying. is it the case that it works perfectly with regular btc, and is not confined to tbtc (your slide said grin<>tbtc)
jaspervdm
@jaspervdm
tBTC = testnet BTC
sorry for the confusion :)
johndavies24
@johndavies24
@knaccc the ETH version of BTC is WBTC I believe

@buddies2705
how many nodes are there in Grin network?
Blade Doyle
@bladedoyle
@buddies2705 Oh thats fun! I found mine: http://grinnodes.org/

@johndavies24
yeah, mine is a littttttllle too accurate

Which wallets currently support grin?
CryptoZink.io - Price Index, Guides, ATMs, News

@johndavies24
@cryptozinkhq_twitter get out of here with that crap
@hokkanen main ones are grin reference wallets (CLI), Griin++, Niffler, wallet713 (CLI). But there are others

FYI, most users have moved over to Keybase now. You might get better help there

@energyburn Grin brought me to the exchange, did not receive them. Can you check the transaction, is everything all right?

For the C31/C32 POW algorithm, it really the best design in all of the POW which have been seen.
mcminer-thomas
@mcminer-thomas
C31 need 256MByte SRAM build in side on die, while C32 need 512MByte SRAM , which will need more than 600mm^2 area in 16nm node. This only Storage been included , cores and matrix bus between the core and memory is needed. Also some art work of compression is needed , fail rate of the SRAM need to be handle. So one 25mm25mm even a 25mm32mm die can not handle it . ------ while 256Mbyte SRAM for C31 can be handled in this case , get a good performance.
mcminer-thomas
@mcminer-thomas
So C32 is just he best way to have logic die , memory die external , and smart algorithm. It looks balance , a good architecture to follow the industrial trend. If C32 can be make in one chip then , it will loosing the chance to run up and go strong with his Low inflation , unlimited distribution concept.
So far so good now.

256/512 (C31/C32) is needed for Edge memory but you need to include Node memory for another 256/512 pool respectively, for a total of 512/1024 memory in a single chip. Alternatively, you can use TMTO at some performance penalty eg. 1/2 C32 performance at 768MB or 512 edge + 512/2 node or 1/4 hash at 640MB or 512 + 512/4

2 issues with ASICs using external memory are granularity (cost) and performance (bandwidth). External memory ASICs will be worse than than a GPU because of memory_granularity/data_bus_width constraints.

ePIC Blockchain - Henry Quan
@ePICBlockchain_twitter
Bandwidth of 768-bit wide GDDR6 and 4 channel HBM2 were about 1/100th of that internal memory. Power consumption will be much higher. (too lazy to do the math).
Unless you use the same memory bus width as a GPU, performance will suffer. However due to memory granularity, you will be burning money on memory size to maintain the memory bus width.

Please tell me why they disappear peers? The synchronization process stops on the node what to do?
