Wish I'd known that before I restarted my client. Wink

The hash I have for height 2210496 doesn't match the hard-coded checkpoint.

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

It would be nice if a checkpoint would be added at around the height of 2200000.

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.

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...

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.

I added 203.20.114.252 as a node in my config. It seems to work, but it seems that few blocks are missing.

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
d4065b408236f6189b9fb9fac9e94e5c73b3cfa441671dde720b279246c739b7

getblockhash 2230000
42e6eb6fad7ba9740a99e59c6f066953090487db0f3902850c0145cdb7caa7d8

getblockhash 2220000
383a94e9900d876d352dbfeddae0c01c35e9880b960cf5a18ea681a70373f251

getblockhash 2210000
5facbdea1feafb25e6a94c395955b0f6f02971f3e20d8ec462aaf94923d35845

getblockhash 2200000
8f5c3df4ac4b15d68b9c3f24c172a67ba630e0a4b0d13dbd564a02d1b5a1f539

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

.

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?

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/

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?

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?

How many people are running this at the moment? I'm currently syncing (from back in 2015) but connected to a single peer only.

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/

edit: I can see the same peer listed back in May 2015 when it seems I last ran the client. They connected to me today (rather than me finding them), which I guess means their client has been trying to connect to my IP for over 2 years. Persistence really does pay off...

I tried the bootstrap last 24 hours. It loads the block for 4 hours then crashes. It repeated few times. Can I sync my wallet without bootstrap? Just downloading blocks from the beginning.

Hi Tara11,

Please share the error you found in the debug.log at the time of the crash, or if it was an exception printed to the console let me know what you found as the error.
Also, could you tell me a little bit about your system? Are you 32-bit, 64-bit; running on Linux or on Windows? Which version of Windows/Linux?

Let me know what happened so we can figure out what went wrong.
I know @bee7 was able to use the bootstrap.dat without significant difficulty earlier this year -- so I'm hoping the symptoms of your problem may just be related to disk usage or memory exhaustion or something simple to troubleshoot.

Best Regards,
-Chicago

Hi, Chicago. It loads the wallet for few hours. Then crashes without message. I'm using windows 7 32bit. I used every single nodes written in this thread. Without bootstrap it says no connection to network. But I can see my balance unconfirmed.

Hello, Is this still alive? I invested whole bitcoin to grain nearly 4 years ago. I already lost hope for recovering that money.

Any working nodes? I want to sync my wallet.

Oh my, I am sorry to hear that... If you just lent that BTC or invested it conservatively it could be 2-3 coins by now. Oh well

I was really noob then. Glad my ethereum investment went well. I bought it when price was 7 dollars each. Cashed out half of them and holding another half.

Hi Tara11,

You can obtain a linear bootstrap.dat of Grain at height 2,210,496 from March of earlier this year here.
