Works for me, awesome!

Really good job ;)

Wellenreiter

Good work Lizhi,

I will try to compile for Linux in the next days. I don’t have a windows environment available.

mirrax

You did a lot of work Lizhi!

good job.

Great work, wallet has been backed up but new code works like a charm.

If you sync all blockchain,it will spend about 12 hours.

Today, the birth of the first multisig address.I create a 2-of-3 multisig address using addmultisigaddress.

I have 3 feathercoin address : 6xvtGPDGLVWrzJUynPcFk4sqZDHZKxMP9j ,6vBqGpjnykXMnukGYrwpa3apUY9ExUw1ac,6q5UfxDFyDxhfgYbQ9mPGqMgpUKQdFB5kw ,then I get their public keys using the validateaddress RPC command 3 times.

feathercoind.exe addmultisigaddress 2 [\"03955c4823b6e410b86b992888dc3cec756b2845dda3c6de9ddb71a5e2c6e33915\",\"0315ef1ca1a375de78fa01e1cba96881fe873d7102a8cd3f309e2a3f8e29debe37\",\"03b15fab5adabf3767f801a68b189e68c27936870f9e3a1dcb4df5d9724d9c32c4\"]

addmultisigaddress returns the multisignature address. It is 3FRL69QcG5PSNzgQMwN7qSzfrZY5zDYBUo

Thank you lizhi!

This is remarkable…

This plus 2fa, dark addresses and bitmessage implementation, will = one very powerful Qt

I did not have to resync my wallet, just changed to the new exe.

New wallet is also faster than the 0.8.7 code

MrWyrm

Fantastic work. I’m very excited about Multi Sig.

Yes, New wallet have DNS Seed Service, It will automatically connect default fastest full node (eg:pool.ftc-c.com,pool2b.d2.cc). They will be the default settings in your peers.dat

Today , I finished a multisig transaction. I sent one feathercoin to a 2-of-3 multisig, then spend them. :)

My multisig address is 3PjAax8rHZpaYCBy4GYc9rcQNFTKYukaWF .

How to create multisig transaction ?

This is a complex process,You need to install two feathercoin core , test a 2-of-3 multisig transaction. Soon after, I will write a special manual for multisig transaction.

about more multisign information ,you can see them.

Now , You can compile feathercoin core in linux. I test with Ubuntu 12.04 64bit.

Install Dependencies

apt-get install git
apt-get install build-essential libboost-all-dev libcurl4-openssl-dev libdb5.1-dev libdb5.1++-dev
apt-get install zlib1g-dev libminiupnpc-dev autoconf
apt-get install autotools-dev autoconf pkg-config
apt-get install libtool

Install BerkeleyDB.5.1.29

tar -xvf db-5.1.29.NC.tar.gz
cd db-5.1.29.NC/build_unix
    BITCOIN_ROOT=$(pwd)
    BDB_PREFIX="${BITCOIN_ROOT}/db5"    
    ../dist/configure --enable-cxx --disable-shared --with-pic --prefix=$BDB_PREFIX
    make install

compile feathercoin-core 0.9.3

cd feathercoin_core
./autogen.sh
./configure --disable-upnp-default --disable-tests  LDFLAGS="-L${BDB_PREFIX}/lib/" CPPFLAGS="-I${BDB_PREFIX}/include/"

make

May have a problem:

libbitcoin_common.a(neoscrypt.o): relocation R_X86_64_32 against `.rodata’ can not be used when making a shared object; recompile with -fPIC

You need to modifysrc\Makefile

CCASFLAGS = -g -O2 -fPIC
CFLAGS = -g -O2 -fPIC
CXXFLAGS = -g -O2 -Wall -Wextra -Wformat -Wformat-security -Wno-unused-parameter -Wstack-protector -fstack-protector-all -fPIC
OBJCXXFLAGS = -g -O2 -Wall -Wextra -Wformat -Wformat-security -Wno-unused-parameter -Wstack-protector -fstack-protector-all -fPIC

Hi Wellenreiter, I think you should try to compile bitcoin-core 0.9.3 , I guess your boost-lib need update. I can compile in Ubuntu 12.04.

I set up a full node with feathercoin core 0.9.3.

https://bitinfocharts.com/node/120.24.208.220

Wellenreiter

That one was a bug in the boost libraries.

solved.

Let’s see what comes next ;)

lizhi

Today, FTC wallet can team working with Bitmessage. Bitmessage can been launched from the Feathercoin core.

Core wallet can pass parameters to Bitmessage, include Address,TransactionID, amount or more. They can automatically fill in to subject .

Bitmessage version 0.4.4.

MrWyrm

Wow! Now this I like! Top work Lizhi.

tmuir12

Cool!

mirrax

I just wonder.

Is it possible to have both latest official wallet and this beta release at the same machine with the same time opened using same wallet.dat?

Or more important is it safe to execute such setup??

MrWyrm

That’s a good question. I’d like to know that too.
