A blockchain store for embedded devices would be a plus, I'm having space problems on a 50GB VPS.

For static data compression is usually a good thing, actually a compressed representation for block and transaction data should be a milestone for the P2P network.  Compress once, read many is "always" a win for space/time/energy/ect.  If I'm not mistaken the LevelDB supports compression, it may already be compressed and in that case further compression makes the storage requirements larger.

Do you have any good idea for small memory embedded devices optimisation.
Bitcoind used at least 256MB mermory, but many devices only have 128MB physical memory. Swap space is need but slowdown the whole system.

You can compress and store the blocks files in a SquashFS file, and merge it with overlayfs to daemon directory. my ~36G data files requred ~26G space.

Once, if i got time, i will write a howto for linux.  Undecided


I am worry about compress data blocks would slow down the performance of bitcoind and router.
Now, my router is loading is about 4.x average

Now, you can run your bitcoin full node on your route

I have porting bitcoin node to OpenWRT as a packages, and you can download here
https://github.com/jimmysitu/bitcoind-openwrt-packages

This package is tested on my HiWifi-HC5761, with 32G SDCard as blockchain data storage
https://github.com/jimmysitu/openwrt-hc5761/tree/bitcoind
You can compile your own firmware with bitcoin node installed if you are using HC5761

Enjoy running a full node for bitcoin network!
