Block chain size/storage and slow downloads for new users

[Meuh6879]

And after the download of the bootstrap.dat ... the bitcoin core job to extract all to recreate the block folder (in blockchain folder).

"Deleting" old blocks is required, it should be easy to implement. Only require to clients remember up to 4 levels of transaction tree history. Now its like 300 000 levels of transaction tree required no idea why.
It would be great for bitcoin adoption

It took me 23 hours to add fully functional bt-core on my MAC. Downloaded bootstrap.dat and synchronised with network. Macbook is new, but process was so slow.

If you don't need the full functions, consider getting a light weight Bitcoin client. Full node requires CPU to verify blocks and memory space. They can be reduced by using a lightweight wallet as you do not need that much hard disk space because you do not need to download blocks. This is also the fastest.

If I use Multibit, I assume I am  not contributing to the bitcoin network by allowing others to connect to me and download new blocks from each other. Wouldn't this become an issue if the majority of the users started to use an SPV client?

thanks for update

yes ... but, it's the final deal.
pool and miner must have a strong source for the block verification.

so, if you have strong miner, you always have strong complete source of blockchain at the end.

Great! Thanks guys for this thread

[kelvrhy]

Thx for your explain
So helpfull

Not really, merchants would still be relying on full nodes to process payment as SPV clients isn't as secure as Bitcoin core. There will also be some people willing to run them to support the Blockchain. You aren't contributing much unless you turn on your computer for 24/7 as Bitcoin need more nodes with more reliability and uptime.

Yeah it feels as if I have been waiting for an eternity. Gets a bit too much on my nerve. Takes forever to download. Please solve the matter as soon as possible.

Starting from a few days ago, MultiBit is the default recommended desktop client on the bitcoin.org choose your wallet page. MultiBit is a what we call an "SPV wallet" so is capable of processing thousands of blocks per second, and its checkpoints are refreshed frequently enough that for brand new users, they will usually be synced with the chain in 5 seconds or less. I'll explain a bit more about how this works in a moment, as we have many newbies join us in recent months who may not be familiar with the details.

[Meuh6879]

so is capable of processing thousands of blocks per second

No.

It retrieve merkles trees of the blockchain ... it process nothing and it "must have" nodes of bitcoin core to emit and receive transactions.
Like all android wallet, too.

[micax1]

is there a new version?
Thank you.

I'am not experienced in those stuff , but if I use Bitcoin Core (with sync) & Multibit (without) , what would be the difference exactly ?

Bitcoin core downloads the entire blockchain and allows you to use features like BitcoinRPC but Multibit connects to their server for the blockchain and checks your balance there and don't allow RPC features. You have to trust MultiBit servers to have valid information for your wallets. Bitcoin Core does not need to have trust since it finds the longest valid chain from a couple of nodes.

[Orangina]

Oh , now I understand much better . & what's the RPC Feature please ?

[ranochigo]

Oh , now I understand much better . & what's the RPC Feature please ?

It is basically a command line which allows you to connect do a lot of things, for example sending balance and checking balance, check node status etc. You just need to set Username and password on the configuration file in the directory and you can implement into your script. This is useful for developers which operates a online service and needs instant withdrawals, once a user initiates it, the script can send a command and the coins will be sent instantly.

This article says the blockchain download time will be reduced dramatically with the changes mentioned:

http://www.cryptocoinsnews.com/bitcoin-blockchain-initial-sync-time-dramatically-reduced-headers-first-sync/

Is this true? If so, when will the new Bitcoin software be released?

There must be an error in this article because it says the new version of Bitcoin software will be 0.10. Yet the current version is 0.9.3

So that might mean that we eant to eait for some time more or the version they wrotr may be wrong or maybe the entire news. Lets wait till cire devs come.
