[Dev] Develop new core 0.9.3 for feathercoin, together

Jeez… and that’s why we trail behind and implement fixed versions or better versions…

So there’s an issue here?

I create a Multi-Sign transaction,send 1 ftc to myself, the multi-address is 3FRL69QcG5PSNzgQMwN7qSzfrZY5zDYBUo. It look great.

how to create a multisigaddress in 0.9.3 ?

You will get a multisigaddress in wallet.

“address” : “3FRL69QcG5PSNzgQMwN7qSzfrZY5zDYBUo”,

More info on the Litecoin Multisig “bug” on Github. First ever Litecoin hard fork…

Re: Need to make sure FTC multisig addrresses also is not start with 3…

**wtogami ** commented
an hour ago

I agree it has been a problem. #blamecoblee =P The unfortunate problem with this type of transition is that it would require the first ever hardfork in Litecoin’s history. Can the plan be written in a more detailed proposal in the format of a Bitcoin BIP? We will need to propose it to the community, receive feedback and buy-in from stakeholders.

lizhi

Yes, I find FTC multisig addrresses also is start with 3…

The unfortunate problem :'(

It is not a bug, However, it is easy to make us confused ;)

A back in github

“I think you can contact Quickwallet (https://twitter.com/quickwalletcom), they are huobi store’s website, is to use Multisig addresses versions are ‘3’.”

We can not modify rpcmisc.cpp.

I got the 0.9.3 core compiled on OpenSuSe 12.3

It was a bit tricky, as OpenSuSe uses non-standard directories for 64bit libraries and the dependencies are always a challenge ;)

Good Work Lizhi!

I noticed that I can’t create qr-codes in the ‘receive’ tab,although I configured with --enable-qr=yes

lizhi

I think we need to support qr-codes ,I will read 0.8.7 codes , then find them.

Re: Multisig prefix, same for Bitcoin, LTC and FTC.

I note Charlie is proposing multiple start values for LTC, al la Ghostlanders solution for the genesis code confusion between coins.


I think changing Litecoin multisig prefix is a good idea. Anton, are you suggesting doing this as a soft fork? Basically, we can have it so that new versions allow both '3' and '4' addresses. '4' addresses will be rejected by the network until the soft fork happens. If you can write up a detailed proposal, that would be helpful.

I realise that this would need its own development sub area. But this will cause a lot of problems to exchanges and merchants accepting multicoins, so would be a killer feature (over Litecoin) and may not require a hard fork if it is developed before release. Although I haven’t had time yet to fully investigate the details of the development of multisignature technology.

so how difficult would it be to change our multi sig address to something other than 3/4 e.g. 9 or whatever.??

lizhi

Now, Core Wallet support QRcode, I will continue to complete QR-snap.

tmuir12

Wow, you have been busy, would be great to get this made the official wallet soon

I think changing Feathercoin multisig prefix is a good idea, But I need helpful.a detailed proposal.

I solved the issue, Core wallet can support QR-Snap .

I must modify ZebraCrossing, Because it compile on Visual Studio 2013 only.

How to compile ZebraCrossing

 cd /D/FTC/dev/ZebraCrossing-master
 mkdir mw
 cd mw
 cmake -G "Unix Makefiles" ..
 make

then libzxing.a copy *.a to /D/FTC/dev/ZebraCrossing-master/build32/Release

You need to modify some files

BitMatrixParser.h and DecodedBitStreamParser.cpp, create a new stdint2.h

typedef long int int64_t;

LinesSampler.cpp

add #include

delete using std::abs;

I had add USE_ZXING option to configure.ac , A simple way is to directly modify src\qt\Makefile.

CPPFLAGS = -I/D/FTC/dev/ZebraCrossing-master/src/libsrc
LDFLAGS = -L/D/FTC/dev/ZebraCrossing-master/build32/Release
LIBS = -lzxing -L/D/FTC/dev/ZebraCrossing-master/build32/Release
