blockchain?

[JohanS]

If bitcoin become more widely used and the numbers of transactions increase, the size of blockchain will increase, right?

At what point will the size of blockchain become an issue/problem?

the blockchain can be pruned if the space becomes a problem

[JohanS]

Ok, of cause.

... and all transactions will still be tracable as the "old" parts will be available, even if they no longer are a part of the live chain.

Anyone have a guestimate on at what size this can happen?

50 GB

100 GB

1 TB?

I use blockchain.info

The answer is it depends. It depends on the amount of memory and bandwidth people have.

Currently, 4 TB SATA hard drives are readily available. I think in general, hard drive storage capacity will outpace growth of the blockchain, (Here is a nice graph of its growth: https://blockchain.info/charts/blocks-size) At 4 TB, a single one of these drives could hold a blockchain 400 times as large as it is today. But I agree that at some point, old historical data should be relegated and only "newer" data by some criteria should be required for a functional wallet.

Starting to become a problem for some users.  There are many wallets that do not require you to download the whole blockchain.

If you have such drive then it's OK but not everyperson has such hard drive.

A better question to ask is: does blockchain grows faster or slower than cost of storage diminishes? Remeber your hard drive five years ago?

All this has been discussed at length and in depth. Try bitcoin wiki and stack exchange. Even better, do your own research, calculate, and arrive at your own conclusion.

Here are some leads:

Note the log scale.

HDDs are cheap, size can keep incresing.
