I cant find the dero blockchain data folder…

edit: Ok i found p2pstate deleted and i get the same thing

Windows users can find dero-chain-data folder in their user folder or C:\ProgramData\dero\lmdb. Linux users search for ~/.dero/lmdb/ in home folder.

Also you can search for file data.mdb in your drive, it should be in lmdb folder. Replace it with http://seeds.dero.io/data.mdb

Fixed. I deleted the blockchain folder and re-sync. Thanks !!!

Pls update your daemon https://github.com/deroproject/dero

Download linux pre-compiled daemon from https://github.com/deroproject/dero/releases/download/v0.11.5/derod_linux_amd64_v5.tar.xz

Run you daemon with following option atm:
derod --add-exclusive-node 89.38.97.110:18090
Windows pre-compiled binary will be updated in next few hrs.

Follow twitter for updates.

and for windows? i took the daemon from the “March 3 fix” posted by Serena but the daemon get stuck here :

i delete the p2pstate and data 2x times but still the same. Thank you

Hello Lez,

I’m sorry that the daemon is causing you troubles. The Windows pre-compiled binary will be available very shortly which should help resolve this problem.

If you’re able to hold tight for just a little longer until the Windows version is available it should help clear up some of the errors you’re seeing.

I’ll stick with you until we get this sorted out :slight_smile:

Regards,
Serena

Ok np, im not in a hurry just saying :slight_smile: and thank you for your answer

Windows and Linux binaries updated. Pls download latest https://github.com/deroproject/dero/releases

I downloaded the latest release dero_v6_windows_amd64.zip and launched derod with following parameters:
–add-exclusive-node 89.38.96.169:18090 --add-exclusive-node 89.38.97.110:18090 --add-priority-node 89.38.97.110:18090 --add-priority-node 212.8.242.60:18090
Before I deleted C:\ProgramData\dero
Finally the derod could not sync beyond 35700 block:
35700_stack

Hi Mik,

This issue will be resolved very shortly and this should no longer be an issue.

For now, can you please delete your p2pstate.bin, delete your imbd folder, restart your computer, download the compressed seed (http://seeds.dero.io/data.mdb), and use the following nodes --add-exclusive-node 89.38.96.169:18090 --add-exclusive-node 89.38.97.110:18090

As soon as the team rectifies the fork issue we will make sure to post updates on all of our official channels of communication.

If you have any issues after these steps let me know and I’ll help you get this sorted out!

Download and replace data.mdb from http://seeds.dero.io/data.mdb
Start derod daemon with following options and let me know if any issues.
derod.exe --add-exclusive-node 89.38.96.169:18090 --add-exclusive-node 89.38.97.110:18090

Hi i just had to reply to let you know the wallet is working fine on windows. " dero_v6_windows_amd64 "
This wallet will sync on its own but freezes at 35700 - 38800.
after that you Have to run the derod from the cmd with the ( derod.exe --add-exclusive-node 89.38.96.169:18090 --add-exclusive-node 89.38.97.110:18090 ) or it will never finish syncing.

*I did not need to download the blockchain file

Thanks everybody for the help ! With downloaded data.mdb and using 2 exclusive nodes, synchronization is OK. The -cli wallet shows correct balance, nothing is lost for me.

Hello everyone, at the time of this post you should no longer have to start with the exclusive or priority nodes and you may once again start by simply opening derod.

If you’re still running into blockchain synchronization issues, please see: (Blockchain synchronization quick fix Mar.4/2018 **Updated**)

Issues still persist, I started syncing a new wallet on another pc, ran derod from file folder, at block 28000 block syncing froze, after closing and re starting derod from the cmd ( derod.exe --add-exclusive-node 89.38.96.169:18090 --add-exclusive-node 89.38.97.110:18090 ) syncing continued.

My other wallet that previously synced up to 42000 will sync without the need for the exclusive node or running from cmd.

Hello beaver,

Can you please delete your p2pstate.bin file and your imbd folder which should be located in your programdata folder. After that you should be able to do a complete resync by only opening derod without having to use any commands or priority nodes.

Please make sure not to sync using the priority nodes for the time being as they’re no longer needed and in something similar to a maintenance mode.

If you’re still having issues please don’t hesitate to contact me and I will help you until we get your issue resolved.

Edit: The network has been working excellently for the last 24 hours and the root cause of the issue should be almost 100% fixed now.
