[ANN][GRA] Graincoin - PoW/PoS coin | Fast, secure | Version 1.6.2 Release

[Chicago]

The starting height of the peer is much higher than the block explorer's current block, which would normally suggest a fork, but the explorer seems to be stuck in 2016: http://explorer.graincoin.net/

Hello Almighty Ruler,

    After reading your message, I started my node but haven't synced with anyone.  The timestamp of the last block I found on the network is 1491352187 at height 2256566.  I'd like to sync with your node to see if it is the same chain just with more work. Would you ask your Grain.conf to enable the IRC functionality so peers may find you easily?

Best Regards,
-Chicago

I did enable IRC briefly, but it fails with "Couldn't look up your hostname" and then closes the connection. I guess the IRC server doesn't like that my IP has no reverse DNS lookup.

You can addnode to 203.20.114.252 which is a 24/7 server that allows inbound connections. (edit: I have another peer connected now, maybe this is you?)

height=2241978 hash=0536fba30734973492696693b12c407a6461fb06dd7abed90bc9dcd29a3277ff

edit 2: Sigh, your 2256566 is higher than my height, and I can see PoS blocks being minted (not by me) right at this moment... so I guess we have a fork...

Current best from my POV:

08/31/17 09:09:49 SetBestChain: new best=00000193e81df87dcc61  height=2242037  trust=32970349440785  blocktrust=1815985  date=08/31/17 09:09:34

How does your trust value look? Greater or smaller than 32970349440785?

[Blackspoon]

I have synced too. Two full days with the bootstrap.dat  .

The irc isn´t reachable for me. Maybe because i am running a IPv6-Network with DS-Lite. The client says that the connection timed out.

I added 203.20.114.252 as a node in my config. It seems to work, but it seems that few blocks are missing.
I try to keep my client up. My Node Adress is: 2a02:908:8a5:729c:b039:dd19:6971:c3a8.
It would be nice if a checkpoint would be added at around the height of 2200000.

Is there any chance that the devs will come back and maintain this project or is this only time wasting to run the client?

Yeah, we really need to figure out the fork point, and decide on which chain to make official with a hardened checkpoint. I'd prefer to stay consistent with Satoshi's original method of resolving forks, and stick to the one with the most work (the highest trust= value). At least one person is minting PoS blocks on the chain I'm on.

Here's some of the blockchain from my POV:

getblockhash 2240000

This goes back to December 2015 so it's pretty coarse. Would be easier if the block explorer worked - maybe that has wandered off on its own fork...

I'm looking into my transaction history. Just realized it was pos coin. I was mining 4000 coins nearly every minute lol.

Hi Tara11,

    Whoa, cool!

    I started my node which has the bootstrap.dat loaded into it.  Just make sure you put an irc=1 into your Grain.conf and your wallet should find the swarm.

Hello, bootstrap taking forever to load. I don't know when will it finish loading.

Yes, it is annoying.
Other blockchain apps support multithreaded import or at least extra tools to import the blocks but since grain isn´t maintained by devs it took several days to import 2,210,000 blocks.
When the import is finished backup the data directory to have a "clean" blockchain ready to be synced up when bee7 will finally relaunch the coin.

Hi Blackspoon,

    We added a checkpoint at height 2210496 back on March 16th of this year.
    Though there were no Windows / OS X or Linux releases made at the time, the source code is there for anyone interested in running a node with the included checkpoint.

Wish I'd known that before I restarted my client. The hash I have for height 2210496 doesn't match the hard-coded checkpoint.

Would be really handy if there was an RPC command to prune the blockchain to a specified height, so when there's a fork we didn't have to delete everything and resync from block 1...

Hello Almighty Ruler,

    Would you kindly run a getblockhash on 2210496 and then a getblock on the resulting hash and share it with the group.
    Back around page 12 of this thread we began seeking the best historical copy of the chain.

I've already rolled back and I'm resyncing...

In debug.log, what's your trust= value at your current height? That will determine if the one you're on, or the one that I *was* on (I can restore from backup if necessary) has more cumulative work. Greater height does not necessarily mean greater work.

A few days ago my logs showed it was at trust=32970349440785

Hello Almighty Ruler,

    Keep in mind my node is not online all of the time and I only brought it up earlier this month by request earlier in this thread.
    With that being said, I started Grain this evening and as it launched, the debug.log indicates the following information per your request.

Code:

LoadBlockIndex(): hashBestChain=aaecb78567becb5b8213  height=2256566  trust=36577501037171  date=04/05/17 00:29:47
LoadBlockIndex(): synchronized checkpoint 1e4e17cf6e6d757540b5d306578b1ce8ed44f5189bc66c893acba0307953f571

    Though, I think what I *should* do is start a separate instance of Grain and import the bootstrap.dat there without connecting it to the network so I can report the trust value from the block we suspected was the tip of the chain back in March of this year so we can see if yours has more work.

The chain you're currently synced to has a much greater amount of cumulative work than the chain I was synced to up until about 24 hours ago. Unless there's some reason you don't believe your chain builds from the checkpoint, I think yours wins by miles, and there's no need to check again via a clean bootstrap.

My client has been gradually syncing but it's sporadic. Still stuck more than two years behind. I have two peers at vastly different starting heights - possibly also different chains - so I guess it's confusing the client.

[bitcoinm3ster]

my wallet finished downloading all but it doesn't sync in the end,  v 1.6.2
any ideia ?

[Pascal Parvex]

Still got the 10K giveaway grain from the very beginning. Got the new wallet, but now blocksources.

[almightyruler]

Can someone who is on the 'long' chain please post (or PM) their IP so I can -connect to it?

Anyone who has this hash at height 2210496:

> getblockhash 2210496
0b3cd9beae759a73ef5c0f96c34cf8bcd7c9a4f46573aad449e38f2708db588b

My client seems to have followed the wrong chain, so it is stuck at the hard coded checkpoint.

[TorisZA]

Also looking for addnodes here if somebody has a synced wallet

Trouble is that there's currently two different versions of 'synced wallet' - we have at least two forks...

this node is offline, can anybody tell when there is a online node?

[almightyruler]

I've taken my node offline because, without a specific peer that is known to be on the better chain, it keeps wandering onto the 'shorter' (wrong) chain. There's no point perpetuating the wrong chain. Still waiting for anyone who has a hash of 0b3cd9beae759a73ef5c0f96c34cf8bcd7c9a4f46573aad449e38f2708db588b at height 2210496 to post their IP!
