Test compatibility of statesDB to add UBI

Not a real issue...

I kindly ask you to add my pool to the wiki:

http://music.mypool.online @minecoins

Thank you!

When I try to run gmc I got this error. I use ubuntu 16.04
~/go-musicoin$ gmc console
No command 'gmc' found, but there are 23 similar ones
gmc: command not found

As pointed by MyEtherWallet/etherwallet#912 (comment) we may need to consider a fast-forward implementation with EIP 155 before UBI. It seems time is quite limited, so another option is to put to v2.x .

Really appreciate MEW community to point this out.

As Geth introduced light protocol after 1.5, it's not a good idea for musicoin to choose it too early before its getting mature. In this way, we will not keep it sync up with Go-ethereum.

From several cases finding Geth can't discover the default boot nodes even its' set in bootnodes.go file, the earlier chain seems easier to discover other nodes from network.

Coins per block: 314 MC
Genesis: Feb. 11th, 2017 (No ICO)

hi sir i am running music coin pool http://drowningpool.net/ but the block value is not showing as 314 and also miner not getting correct share . as right now its showing 5 but it suppose to show 314 . i have already modified in payouts/unlocker.go as .

and then i use ./build

but still its not showing in pool front ends and also miner not getting correct share and it work as 5 value not 314

Can any one provide solution

Original:

Now, current release filename is same with all version.
release name is "gmc-linux-amd64"
missing the download file version checking, it may be using old version's gmc node.

please making compress and file name will include version or git tag number, for not confusion what using version of sw.

Issue by Varunram

Originally opened as https://github.com/Musicoin/PM/issues/117

We have to add Replay Attack Prevention (EIP 155) which has been referenced over at the go-musicoin repository. I've added the steps t doing this below.

On the way to adding EIP 155 support there exists<a href="https://github.com/bitcoin/bips/blob/master/bip-0044.mediawiki'> this issue with BIP 44 that we must comply with. Once we comply with BIP 44, we can get back on MEW and once we somehow implement EIP 155, we can shut the haters over at the MEW repo.

Let's set a timeline for this before/after UBI,

I followed the intro guide on this paged to the T. but can't seem do get this to run.

hey guys we have the config like this but the block rewards are not chaning over to 314 is this correct

After UBI the block reward should be changed to 250 or even better, elaborate on the reward distribution.

Since updating to Music 2.0 my node consistently crashes. I've been running my pool for 5 months on the old version without a single crash.

I was on Go 1.6.2 and thought that might be the problem so I updated to Go 1.7.3 and the crash still occurs.

Do I need to rebuild after updating Go?

Here is part of the log file: https://pastebin.com/StytEDtQ

To catch up the circulation of transactions following Musicoin’s Pay-Per-Play needs and prevent from deflation, there will be a parallel issuance to ease the market needs from a reservoir. The reserved money supply will never be used unless there's over-heated market demand.

Although there's no direct evidence to link to memory leak of geth, it's a big concern to us to apply geth as major client of musicoin community. It's easy to trigger the whole network into a havoc if it's not fully safeguarded.

Do you have any idee where is the problem ?
Thanks

We are going to finalize a solution on money supply, including block time spacing, reward per block, and any increasing/halving strategies. In theory, the direction of Musicoin money supply will grow with linking to transaction volume. So it's not Bitcoin's halving strategy, nor steady supply of Ethereum. Will explain in design document, but leave this section open to public.

Since we are going curb some unexpected contracts to be deployed on Musicoin blockchain. We will set a gas limit in the whole chain to hurdle some of malicious contracts to abuse the system.

Don't understand, there's always a lower height block being mined even the height blockchain has been mined very tall.

Hi,

Recently we have found out on our pool that sometimes when our software (open ethereum pool) tries to insert new block, GMC creases with the following error. According to our logs this started to happen after migration to v1.1.0 (very rarely), and today (29 Aug) it happened over 10 times. Now we migrate to v1.5.0 but please check that bug is fixed in future releases.

We planned to have a separate chain from Ethereum, but it eventually proved it's still a good strategy to peg with Ethereum for a while, especially after the native support from since Parity 1.8.

However, there are still debate inside community whether to adopt Proof-of-Sharing over Proof-of-stake. As Andre pointed out:

You guys got similar views as mine. Yes, I do think Proof-of-Work and Proof-of-Stake lacks in community purposes to incentivize because they are solely aiming for personal benefits. Proof-of-Share combines both personal and community benefits to keep the network operating in a complete cycle where users other than miners and market players can also reap the rewards. Since Musicoin's coin emission has its limitation in the future (where coins per block will drastically reduced), miners under Proof-of-Share will soon be required to do additional task (such as sharing content) in order to break even on their ROI. 

For example, we could built an embedded music player where anyone including miners can put on other platforms for others to discover songs from Musicoin. Songs on the embedded player will only be allow to play once. New user will either have to sign in through the embedded player or visit Musicoin platform and use the official player in order to play that same song again. We can even have miners to help validate content on the blockchain by playing the song under PPP. There are many ideas that we can iterate, so many possibilities ahead.

It seems off-the-topic, but actually it's related to how to choose future client technology. Parity is definitely good choice, but we need to have some broader thinking over this. Geth seems in abandoning anyhow?

Although we have solid bootstrap nodes in place, seems geth still can't find them with private chain. So whenever the geth restart, they have to be added manually.

Issue by Varunram
Sunday Sep 03, 2017 at 07:08 GMT
Originally opened as https://github.com/Musicoin/PM/issues/118

Golang is on the route to Go2.0 and we should make sure that gmc successfully builds with all future versions of Go. We can keep this as a priority after UBI.

System information

GMC version: gmc v30
OS & Version: Linux Ubuntu 16.04 (upgrade from 14.04)
Commit hash : (if develop)

Actual behaviour

node down with following logs
d4ffe800bc30e3d827@[::]:30314
Fatal: Error starting protocol stack: listen tcp :30314: socket: too many open files

Steps to reproduce the behaviour

full sync mode

reference informations

Above issue already discussed in early season of ethereum (frontier and homestead era) .
I've expanding and tune up my system ulimit and kernel property.
there's still occur, Is there more helpful guide to me.

make gmc
make: *** No rule to make target 'gmc'. Stop.

how to solve this iisue

Since we have studied the blockchain and experiment it for a while, it's clear enough we should set a proper difficult equation to make it suitable to the possible scenarios from miner's community. Since we are going to encourage personal mining activities, the difficulty will be set relative lower at the beginning, but grow based on swarm scale.

• New spec
• Rebuild with changing bin from geth to gmc
• Setting up 2 basic boot nodes
• testing gmc clients on discovering and syncing
• defining new Parity spec into mc.json
• Parity syncing test
• Orbiter test (http://104.199.113.25:3000/home )
• tx test with stress
• smart contracts test
• gas limitation test
• CI and deployment test, musicoin.org, api.musicoin.org and orbiter.musicoin.org
• final test from scratch (redo the check list to make sure they work as expected)
• ready to release

There's an non-official version of Parity-derivative at https://github.com/immartian/rmc , we are working toward to merge into Parity with the helps of ParityTech team. openethereum/parity-ethereum#6621

However, there must be an explicit statement within spec to run Parity with GMC compatibility, which is "homesteadTransition": "0x118c30" to prevent the sync stuck at 1,150,000, otherwise it's all ok.

my nodes is running :-) well still syncing but there seems to be hope.

but for some reason, it is getting killed

System information

Geth version: geth version latest

Expected behaviour

Run in screen non stop

Actual behaviour

Gets killed.

Steps to reproduce the behaviour

hey team was wondering if you can give a small tutorial on installing this stuff, im running windows 10 64bit, i downloaded the windows .exe. When i fire up the exe it opens cmd prompt and just imports blocks, im not sure if im doing what im suppose to be doing. I go my old go-musicoin client folder and only the gmc.exe is in there compared to the go-musicoin 2.0.0 folder i downloaded which has a ton of folders. thanks again in advance, im still new to all this and been only mining for a few weeks.

• Test compatibility of statesDB to add UBI
• Test newest geth technologies but not the hardforked blocks
• Have a clean build for gmc use and release
• UBI insertion test upon v1.1
• (optional) smart contract for oracle solution (leave for contract writers)
• Test debug_trace for orbiter (drop the idea of merging geth 1.7, back to 1.48)
• Remove difficulty bomb (not this time)
• Add "UBI" signal
• Release GMC 1.5 with "UBI" signal and most recent eth tech
• Test UBI scheme upon signaled version
• Test RMC to support UBI
• Release UBI timeline
• Notify all exchanges and coordinate with the hardfork
• Release GMC 2.0 with "UBI" scheme
• Team need to take a break after long time hard work, but media would come soon.

Is it normal operation? and node-restar

Steps to reproduce the behaviour

execute gmcv3 node fullchain mode from scratch.

System information have amd rx-460 8 gig gpu works with nicehash

PROGRAM WITH NAME AMD64 SHOULD HAVE GPU INSTALLED ALREADY SET "OPENCL" AND REBUILD
'I will try but am a newbie here'

GMC version: gmc version4.0AMD64
OS & Version: Windows10
Commit hash : (if develop)cpu only hashing works great but don't want to burn it up, 100% usage

####all attempts of gpuinfo, gpubench,--minergpus 0, are not recognized by program but are listed in help file, set GO_OPENCL and re-build to enable

Actual behaviour, CPU ONLY MINING NO GPU USED.

Steps to reproduce the behaviour

Backtrace looking forward to do some mining here.
