What are the Ethereum disk space needs?

  • How fast is Ethereum blockchain growing and how big is it likely to get in the future? Is it still about 1 GB per month? Are there any data pruning or compression algorithms in place or planned to be used?

    Update: Nov 29th, 2017. Afri has written a blog post about this, esp. parity pruning modes: The Ethereum-blockchain size will not exceed 1TB anytime soon.

    Some Sheet.

    If ethereum gets used as much as bitcoin is today (around 5tx/sec), that 28x the growth rate. Assuming people use more smart contracts and don't just speculate like they do with Bitcoin, you will see lots of smaller transactions. There will be some consolidation as more transactions are mined in a block (which uses a bit fewer bytes per transaction), but overall, I would expect 600gb-1TB per year of block chain growth if Ethereum gets popular.

    @5chdn Assuming these figures are still correct, if I were to set up a new wallet and did my first sync using geth -fast, the bandwidth I would use for that first sync would be around 4.348GB ??? Is that right?

    Yes. Should be a little bit more by now.

    @nchinda2 `0x006ed403807ae87b9f958f25c33862927ba1b57b` :)

    @5chdn shouldn't it be 1.75GB in case of light mode in Geth? I'm in the process of syncing at around block 300k with 140MB of data collected. Looks like it will finish slightly above 2GB.

    There should be the UI option to choose the location of the chaindata and type of sync...

    It's late November 2017 now and my `--syncmode "fast"` blockchain on my computer is now **220GB** in size. I'm concerned I won't be able to operate a full-node for much longer as it really needs SSDs.

    Unfortunately, Geth does not continuously prune the database. You might want to consider using Parity.

    What is the difference between `geth full archive` and `geth full full ` node? @Waqar Lim

    @alper one is a full node (pruned historical states) and the other one is an archive node (all historical states), see https://dev.to/5chdn/the-ethereum-blockchain-size-will-not-exceed-1tb-anytime-soon-58a

  • Currently, the network is growing at around 1GB per month. It's hard to anticipate how large it could grow and at what pace, but there are already efforts underway to implement state-tree pruning in various clients. These techniques will contribute towards so-called "light-clients".

    In linked chart above, Block size evolution estimating block size in bytes over time that can be used to estimate velocity (rate). The most appropriate graph depends on what you mean specifically by block growth rate.

    which one (or combination?) of the charts linked above shows the block growth rate? None of the individual charts seems to show this directly.

    "Block size evolution" will be an estimate of block size in bytes over time that can be used to estimate velocity (rate). The most appropriate graph depends on what you mean specifically by "block growth rate"

    I tried to find a definition of what etherchain.org means by "block size evolution", but I failed to find any. My interpretation (possibly wrong) is that this represents size of individual blocks averaged on a daily basis. To translate this to an estimate of the blockchain size growth rate over a month (which is what I meant to write in my previous message), we'd need to multiply this by the number of blocks added in a month.

  • As of today, ethereum blockchain (ETH, i.e. supporting DAO fork) downloaded in full mode occupies 75GB on my drive. Client is geth (go-ethereum), version 1.4.18, built from source cloned from https://github.com/ethereum/go-ethereum, running on CentOS Linux release 7.2.1511.

    As of today should be, as of mm/dd/yyyy for each and every answer...

  • I've stumbled upon the links bellow :

    1- provides an online chart which presents the Ethereum's blockchain current size evolution alongside the Bitcoin blockchain's size.

    2- provides details about the Ethereum network including the blockchain size https://bitinfocharts.com/ethereum/

    I wonder why my results disk space needs from one month ago are higher than yours now...

    i will update them in few hours

  • As of February 1, the blockchain size is ~940k blocks, with a new block being created every 17.2 seconds. This means, on average, the blockchain increases by 152,790 blocks every month.

    A rough average block size, at this time, is around 1,225 bytes. With this average block size, the blockchain size increase is 187MB per month (152,790 blocks x 1,225 bytes).

  • I'm syncing a node in full mode. At the moment it' on block 5005306 (end of January 2018) and it is 700Gb. It's probably been running for more than 20 days

    Did you use geth or parity. If geth did you use `--gcmode=archive` option?

    geth with the syncmode=full option. I did not use the gcmode option. I dindt even know what it was before your commet. It seems something new on geth 1.8? Im using 1.7

    Yes in Geth 1.8 there is automatic pruning enabled by default. gcmode=archive disables it.

    am I correct in assuming that's new to 1.8? because on 1.7 sync mode full is enough to avoid prunning

    Yes that’s correct.
