Bitcoin Forum

Few weeks ago the number of transactions increased as can be seen here:

As discused in IRC this is not an issue at all, and it has been already documented in the original design paper of bitcoin.

Blockchain size increases rapidly, and this is probably not a problem for desktops or servers, but it is for embedded devices where the disk usage and cpu power are limited.

This is also a problem for new users because they need to download and calculate more stuff before starting to do anything with the client.

I would like to be able to use bitcoin from a pocket device without having to use a blockchain. Online wallets are not an option.

Another possibility i found is the possiblity to modify the client to accept a verified original new root for the rest of the chain. This breaks the design and can be dangerous.. But what's the option? A portable device can validate transactions, so it can check the blockchain, but why store it completely?

I don't really know a lot about the bitcoin source code internals, but I would be interested in having support for this.. or at least find a way to use lightweight clients.

There are lightweight clients for portable devices.

+1 This. Portable devices should never be downloading the blockchain. My android phone, for example, has three wallets. Paytunia.com, Blockchain.info's wallet, and Bitcoin Spinner. They're all like 5mb in total, no blockchain issues at all.

wow thanks was wondering this myself about using portable devices aka my android will check those out

And what about a lightweight client for desktops? (or servers) is there any way to run bitcoind in this mode?
