may i request a copy of the 28gb+ file please ?
A lot of work to be done there, constant incoming blocks and all will be a pain to keep that data updated, would mostly encourage everyone to at least adapt to importing that official raw blockchain and using --verify 0, makes it quit faster.
Though awesome work!
In principle I agree, but I believe the export height of the official is only 200000
Btw, do you know the height of this official export ?
When the official blockchain.raw has height 350000 - 400000, I will take down my file
I would recommend verify on, since my export is not official.
Here is a 4 months old reddit-link on the topic:
I downloaded this blockchain.raw September 2018, if update was pushed of new image, it could be bigger now.
I’m seeing current blockchain.raw from https://downloads.electroneum.com/blockchain.raw is over 13GB which should hold more than 323k blocks, its nice to see it updated.
Now the offical blockchain.raw has 390876! Much appreciated, the download speed was lightning fast. Thanks
Thanks, I’ll remove the download-link to my unofficial .raw
Everyone should use the official trusted source.
The ETN Team is also working on a new checksum feature to speed up import
I get the same error. I think it is with blockchain.raw file. It needs to be updated for the latest changes. @Rach can you please update this file?
i am using the lastest Electroneum 3.0.0.0 from github downloaded
everytime i am getting this error .
help us to solve it .

told u bro i use those last verson of electroneum
also use Blockchain Data : [blockchain]
(https://downloads.electroneum.com/blockchain.raw)
Has the raw blockchain been updated yet?
Dont think so, people are still complaining about failed imports
Ah ok,… will be updated when updated I guess
import was successfully just when i open electroneud its said this error
its import log :

at last i find old version of electroneud for importing block chain
it solved
but when i start_mining its writing :
Error: mining has NOT been started: daemon is busy. Please try again later.
Dear @rebvari
Perhaps you did not realize but Electroneum has forked to the new Moderated Blockchain, The new Proof of Responsibility github files can be found here
I would strongly suggest that you watch the announcement video and read the announcement post.
It seems you are still trying to mine electroneum, which is no longer available.
Thanks
M
