PEERCOIN artwork-original and unique big size abstract painting....price 400 USD www.starttheart.blogspot.com

...that's pretty cool!

@Starttheart do you take peercoin and ship to the US?

Yes

is there an online store i should look for?

Yes.Lets get private,just send you private message

@belovachap make sure you use official channels for payment

after creating my own genesis, i'm stuck at block 1 .. tried CPU mining for 2 days, no block increase

I'd like to use my S9 miners for this but when I type "getwork" into RPC console, I get "Peercoin is downloading blocks..."

are those 2 different errors? or are they related to each other? could someone help me out please?

does S9 support getwork?

@bibz i used a S9 to mine a peercoin-based altcoin. But i did it by setting up my own UNOMP pool, then setting that pool as the stratum host in the antminer.

If you have an altcoin starting at difficulty 1.0 ( << 32) it should be no problem to CPU mine it.

ok great thanks @Nohea

diff is at 1 right now, been running for half an hour aproximatively

but I think its stuck in a loop or something tbh, the debug looks strange

no prob - now you got me trying to find peercoin testnet nodes

by the way, thanks a lot for your commitment to help me. I appriciate that a lot.

actually, starting mining a new chain i fire up 2 different nodes talking to each other. Either on 2 servers, or one server, different directories and ports

I've set up even 3: "connections" : 3,

what does rpc command "getmininginfo" return?

my client has server=0 in peercoin.conf and the others have server=1

{ "blocks" : 0, "currentblocksize" : 1000, "currentblocktx" : 0, "difficulty" : 1.00000000, "errors" : "This is a pre-release test build - use at your own risk - do not use for mining or merchant applications", "generate" : true, "genproclimit" : -1, "hashespersec" : 15216931, "networkghps" : 0.14316558, "pooledtx" : 0, "testnet" : false }

"hashespersec" above zero means you are hashing.

the server=x shouldn't matter, i think that just means it answers to rpc

regarding to my CPU usage its working very hard, but I don't understand why the debug just repeats the same stuff over and over again. I got a I7-8400K, it has like 6 physical cores I think

oh ok

The debug repeats every hashing, it is going to get full quick (log file)

I'm really scared that I've changed too much and maybe I made a mistake somwhere and thats why it keeps playing me. I'll let it mine for 2-3 hours, if no block is mined then I'll start over from scratch.

wait a minute, I'll just remove the -debug parameter

I mean, I've got an M2 SSD, so that shouldn't be a bottleneck, but who knows..

oops, debug.log has already 195.714 lines in it and equals 20MB

it is probably working, but you can't rule out having broke some code. git diff is your friend...

didn't commited the code yet, actually I was planning only on experimenting/playing a bit with this.. but now it got serious

2018-05-03 15:35:52 Running PeercoinMiner with 1 transactions in block (191 bytes) 2018-05-03 15:35:56 hashmeter 15332 khash/s

i'll just hope for the best, otherwise I'll follow your advice and first start from scratch with unmodified code

@Nohea did you mine with the S9 right from the begining, after genesis?

if you did CPU mining, how long did it took you for a block when the difficulty was "1"?

i think on testnet the difficulty is below zero even

was that a block?

I'm not on testnet so I can't confirm that

2 hours almost since its running, no block found yet

I'll try my luck at this with an S9. maybe my CPU is too weak

Can it be that my problems are related to POS? UNOMP just reported: Detected Reward Type: POS

ok I've setup UNOMP. now it works. but I'm mining very very very quick

1 block per second wow something went really wrong

hah! congrats. Yeah an S9 will burn thru PoW like nuts at difficulty 1.0 .

No way

You'd need to get difficulty up to at least 1 million to get a normal block time

does anyone happen to have any primecoin testnet funds?

Here are some peercoin testnet nodes (edited)

Aha I was after Primecoin.. on the offchance anyone here was a primecoin fan!

My PPC testnode is also still active and minting! 128.199.40.99 is available at your service for over a year now.(edited)

No primecoin testnet node or funds though.

You can just start primecoin client in testnet mode and start cpu minting. Will be easy to create a bunch of coins if you find a testnet node to sync with.(edited)

Testnet is about 10 nodes strong now

Yes, actually CPU mining should be fine I suppose

I'll give it a go!

Yes please run a testnode if you are interested in peercoin development!

It helps us with testing tremendously

Just wondering, has there been any discussion of backporting bip32/Hd wallet support to Peercoin with minting support? Bitcoin has it in core now.

I can think of a use case for having it.

I have issue raise for that

waiting for one of core devs to pick it up, I guess I'll have to hit them harder

cool

If you could have a peercoin node w/bip32/HD wallet, you could have it minting, and have a mobile light wallet w/the same xpriv seed for daily use transactions.

yes

that's a fun notice ⭐

Hello I was wondering if devs could help me understand how does peercoin seperate POS & POW blocks for difficulty targeting properly and how does it split the ratio (just the block time targets)?

I would also be wondering if there is reason difficulty retarget has not been changed to something like LWMA/DigiShield, etc, such as a POS issue that prevents it

On our coin thats partially forked of peercoin, we switched to more modern retarget algo and it seems all blocks speed up to ~<1s/block avgs using both LWMA & Digishield, and we cant figure out quite why

Which coin is it?

@Peter Ignition Coin

meh masternodes and low coin count. Not real currency, just a pump and dump thingy.

like Dash?

Pinned a message.

PeercoinOG ?

XD

Btw. segwit won't be impleneted on Peercoin so wtf ..

I guess it's best to be ready

Is there any peercoin guide which I can follow?

what kind of guide do you need?

| peerchemist leveled up!

@saeed.taurus you've asked for RPC docs yesterday and I've linked it to you: https://docs.peercoin.net/#/json-rpc-api-reference

@peerchemist has people developing peercoin change from 2015?

@peerchemist thanks a lot for this. Do you know where can I have some guidance on peercoin form?

Fork*

@Peter can you rephrase that question?

@saeed.taurus if oyu are asking how to fork peercoin and create an altcoin, we do not have any materials which could help you with that

I mean there was a somewhat big debacle after Peercoin blockchain has forked in 2015 into 2 different blockchains. And there were different people to handle this problem(edited)

huh?

there was a minor chain split indicent with this other client (called Peerunity, discontinued since 2016)

but that was nothing major

solved within few hours

yes that's it

Quite different nicks

| Muf18 leveled up!

Lol

hm

different nicks? you mean people who are there are different?

Yea it seems so

sure

Peercoin is old, people come and go

sigmike is still here, sandakersmann, randuev ...

some in that thread I don't even know

Ye

Thanks people!

I read the whole PPC guide

but couldn't find the answers I was looking for(edited)

I wanted to know whether PPC uses the same Key formats and transaction script method as the BTC does?

Please help me with this

It will solve many problems for me

it does use the same key formats and transaction scripts

Awesome

thanks man

is there any dev guide like https://bitcoin.org/en/developer-guide

No, you are welcome to write one though

Awesome !

I'm very new to PPC

So I'll be needing a lill help here and there

I'm really interested in knowing how this hybrid pow/pos works

we'll release a lot of new documentation along with the new website

that's few weeks away

can someone help me compile the wallet on a mac?

where are you stuck?

i'm getting this error: ld: symbol(s) not found for architecture i386 clang: error: linker command failed with exit code 1 (use -v to see invocation) make: *** [peercoind] Error 1

when compiling

any ideas?

| bibz leveled up!

How did you install dependencies

With brew?

Can I see whole log

sudo port install boost db48 openssl miniupnpc qrencode qt4-mac

yes just a moment

i tried it again. i forgot to uncomment build_arch from the macports.conf file. now I redid the whole process of compiling and i'm getting this error instead: clang: error: cannot use 'c++-cpp-output' output with multiple -arch options

no one?

i only work on it in ubuntu / debian

you could run it in virtual box

oh, or use docker. that's pretty good for development across platforms

ld: symbol(s) not found for architecture x86_64 when trying to build under mac osx..

what leads to unstable block times?

| Kek leveled up!

got an altcoin. sometimes block time is like ever 3-4 minutes, but now with a high increase in hashrate the block times are like 15 seconds

Shifts in minting and mining difficulty

Depending on the system

@Kek mac ports i have no idea with, i use brew and i recommend brew

@Kek i agree with backpacker - use homebrew on MacOS, not macports now.
