This looks like a worthwhile update to Zxing, gives improved edge detection for QR codes and more java code converted to C++.

That deserves some (Github) stars, well done.

Well done Gentlemen ::thumbsup:

:D

Up to npw the amswer is no, but we are open to discuss that.

@Cookieboy said in Feathercoin Node:

I did get an ARM version running. I can dust off the builder that I used to get it running. It actually wan’t too difficult, just took a few hours to compile if I remember.

Well, the compile time is related to the arm structure of the pi, which is emulated in Travis.

If I remember right , @uncle_muddy compiled on a hardware Pi and it took more than a day to compile…

Can’t you just configure the Travis containers to keep the compiled binaries and feed the code to Travis again? I’ve seen somewhere, that it is possible to keep the created files in Travis

I’m fine, I’ll find one they accept, one day …

There are a couple of functions to be added back in for ACP, IsInMainChain, GetTotalBlocksEstimate, SetBestChain and PushGetBlocks.

Options to speed up sync - with 0.9.6.1 release
set db cache higher (0.9.6.1 options)
add switch -maxblockorphans=10000

Speed restrictions with Blockchain versions

Version 0.13 contains highest speed increase / work (openSSL replacement), so some FTC sync issue are BTC code restrictions related.

Feathercoin has required ACP to prevent attacks, this works by orphaning none complaint chains until a chain compies with normal rules and checkpoints is longer. 0.13 should fix this issue.

ARM devices, 32bit and old machines will be much slower to synchronize. There is a lot of CPU and Database IO as each full node rechecks all the blocks are correct. 0.11 was sped up slightly, by not exploring orphans if there was a main block.
