I came to notice that my hard drive which is dedicated to blockchains reached maximum capacity and after a little investigation, I discovered that my "blocks" folder in my Ethereum directory weighs 74.5 GB (80,050,787,860 bytes) for 840,984 Files which seems extremely odd.  There's also an "extra" & "state" folder which additionally weigh ~3.5 GB and ~13GB respectively.  Cryptominingblog created a post a few hours ago stating that Ethereum's directory is about 16 GB so this only adds to my confusion.

I invoke the following command to launch eth via a batfile [start eth -d Q:\the.MlNE\Ethereum] within Mist's subdirectories followed by Mist a few seconds later which is of the latest build.

Any help would be greatly appreciated!

My Ethereum folder (C:\Users\<username>\AppData\Roaming\Ethereum) is 10.4 GB, using the Mist wallet in win7.

Almost all of it comes from the chaindata folder from inside.

Wow, that's already messed up in itself. But it's even crazier when you consider Ethereum's launch wasn't even 10 months ago (https://blog.ethereum.org/2015/07/30/ethereum-launches/). Dash was released over 2 years ago and its blockchain is only 1.8 GB as of this writing. Just sayin'.

Guess distributing a glorified calculator all over the world is taking its toll. Nonetheless ETH is gonna have a future on one datacenter or the other...

It is because all smart contracts are stored in the blockchain.

I did recently create a wallet which to my knowledge is a contract of very basic form.  I do however remain a little reluctant to believe that my wallet accounts for over 70 GB of data.

damn i need to download the wallet but if ur saying its so big i cant.

any other wallets for ETH like multibit? or online secure ones?

Unless you absolutely have a need for MultiSig, standard accounts should suffice and consume ~16 GB of space as stated from numerous sources.

Otherwise, navigate your way to MyEtherWallet if you would prefer a web-based wallet.

Sorry I did not see that it was 70GB of data, you might have multiple instances ETH clients?

As stated in my first post, I invoke the following command to launch eth via a batfile [start eth -d Q:\the.MlNE\Ethereum] within Mist's subdirectories followed by Mist a few seconds later which successfully detects my eth node. 

What are the directory names? That have this big amount of data, can you see where the data is stored? Are they hidden files?

It could be multiple chains: https://github.com/ethereum/go-ethereum/issues/1487

                                                  Ethereum/d4e56740/blocks ~74.5 GB
The directory structure is as follows: Ethereum/d4e56740/12041/state ~3.5 GB
                                                  Ethereum/d4e56740/12041/extras ~13GB

You must have multiple blockchains. I'm still not sure what you have in the extras folder though. It might be different clients and blockchains, when the fork happened did you do a geth update?

thats because no one uses Daesh.

That's abnormal, your folder size is high, consider deleting everything and reinstalling again.
Protip: if you run geth.exe with the  "--fast" flag its going to download a trimmed version of the blockchain, making it under 2 GB of size.

I originally launched eth from a Mist distribution of about 3-4 weeks of age.  I never used geth as a node unless Mist is somehow using it while also running eth.

Once eth is launched via my batfile, Mist successfully detects it by indicating it found a running node and thus proceeds to synchronizing the blockchain.  The reason why I insist on using eth instead of geth is because from the information I've gathered, geth does not support solo GPU mining and is restricted to CPU mining only which I have no interest in.  I would be grateful if anyone can shed some light as to which node is the better of the two and whether my previous statement is indeed true.


Is it possible that eth&geth's blockchain differ in size and if not, can the blockchain previouisly created by eth be used with geth or must I re-download it from square 1?

That's a joke, right?  ???

Dudes,

If you are mining on that PC, you could have multiple DAG files.  

On my machine the DAG containing folder has grown to 20 Gb.

I've pruned it back to 5 - 10 Gb.

You can use Claymore's miner which eliminates the need for dag file creation as the process is done less in than 5 seconds via your GPU instead of your CPU cache and memory.

Somewhat Ethereum blockchain size surpasses that of Bitcoin. This will be a serious issue in the future that needs to be addressed.

how you prune it with etheruem?


not for nvidia, clymore is only for amd

Why would it be an issue? HDD storage is dirt cheap and it will be even more so with HAMR (heat-assisted magnetic recording) coming in the next few years and even SSD storage price isn't anything crazy anymore.

Ayers,

I just do a brute force delete of all the DAG files in the folder and rebuild.

Please refrain from deviating off-topic.

theres something wrong there, delete the whole blockchain dir and sync with the command --fast

you should be under 12gb.

Here's another question which may potentially resolve my problem:how would I go about changing Mist's default blockchain directory? 

this is just junk wallet, imagine if you host it bloatchain, it's going to be HUGE piece of crap
yes, ethocreampie going centralized

You're either smoking really good shlt and or using a really bad translator but then again, stupidity has no limits.

The Ethminer forked by Gnoil with version 1.1 also use the on card generation of the DAG, there is no need for the harddrive storage.

how can i use this command --fast?

and which version of ETH i will download?

sorry for this noob question, i am totally newbie in cryptoworld

Math is not your strong suite huh ? ..or doing research on the "coins" you invest in  ::)

[ETH] Ethereum = Scam (https://bitcointalk.org/index.php?topic=707237.0) posted July 23, 2014, 08:24:48 AM

and yeah yeah.. Microsoft, IBM and "Big Banks are "using" Ethereum  :D

..better buy buy buy moar cheap coinz nom nom nom

I keep hearing this kind of justification on how a bloated blockchain should not be a problem because hard drives are now cheap. But really now that hardly means that Ethereum is efficient. It has not been a long time since it went online and we see how a bloated blockchain will be a problem in 5 years time.

Agreed ..that guys comment on HDD space stuck in my craw too.
Weak excuse !

Seems to be an anomaly for the OP here..

Even still it sounds like the chain is already getting large for the short time it's been out.
To me this is a problem for adoption.

You want average users to adopt a coin right ?
Well the larger the block-chain size the more of a problem it will be.
And i see web-wallets as a massive security issue / vulnerability and in my time in Crypto i have never used 1 once ..nor would i.

Crypto has a long way to go still to over-come barriers to adoption.

@Spoetnik. I also noticed that they do not have a light wallet available. Why have 3rd party developers not created one? Is it possible to create one for Ethereum?

Light ? Like Multibit for Bitcoin ?
I always loved that wallet even though having to get the Java runtime is a paid in the ass.
The concept of having most of it all hosted online except the private secure parts locally is brilliant.
A Multibit user will never have to download the whole entire block chain.

I think that is the concept you were talking about.
So yeah it would behoove the Ethereum guys to have a wallet like that.
Ends up being a combo of online hosted wallet and local wallet.. best of both worlds.

How big is the ETH block chain now? Last time I looked it was well over 100GB.
That means it will pass BTC in a matter of months, whereas ETC block chain only seems to be about 1/5th. of the size of ETH.

How big is Eth blockhain now? trying search on google for its size with no luck, etherscan.oi has all the charts minus a blockchain growth one

I just know that it takes a while to download the whole thing, it feels like it takes longer than it would to download Bitcoin's Blockchain....
I'm not complaining though because there's things like Myetherwallet (unsafe wallet).
