[Dev] Nameview - DNS Naming System Built on Feathercoin's Blockchain

lizhi

It need blockstore project , After I build ardroid wallet , I think blockstore run as feathercoin’s side-chain.

I hope feathecoin’s blockchain can support Openname Protocol. I don’t like onename , it is website but not source code .

CKey key;
fCompressed=false;
key.SetSecret(vchSecret, fCompressed);
std::vector uret=key.GetPubKeyU(fCompressed);
LogPrintf(“addressbookpage unCompressedPubKey =%s\n”, HexStr(uret).c_str());

        CKeyID unkeyID=CKeyID(Hash160(uret)); 
        LogPrintf("addressbookpage hash160,unCompressedPubKey=%s\n", HexStr(unkeyID).c_str());
        GUIUtil::setClipboard(HexStr(unkeyID).c_str());

Step one OK . Make FeathercoinPrivateKey(private_key).public_key()

make unCompressedPubKey ,130bytes, like 04edb297ba63c35998ec23cfca60666bb4d0d1c3e810b93d2d20c94e3a129774407b719ecf902de8a20c6d99ed0ad0d8c5af178640fdcb0c5dee26c41d39306998

make unCompressedPubKey Hash160, like 6f01b45dd6685d5ac1717baa46e4cda8287c160b

As an independent developer, You’ll see me strong.

I finish base40.h , It encode strings as base40 .

It can work as a side chain.

I finished openname in our blockchain , It is nameview, It will add a nameview.dat file in your data directory.

You can register a name in feathercoin’s blockchain with your a address.

After your transaction is confirmed , nameview will all registered names.

The Feathercoin - Nameview - (Opennames DNS) experimental facility is now looking for some testing and documentation work.

Feathercoin Admin / Devs are looking to support a school student / or interested hobbies, crypto currency software development in a “Summer of Code” style project.

Any level can assist, beginner to advanced wishing look more into technical development. The scope can be altered to suit.

The worked would be based in the FTC 0.9.6.2 maintenance “Team”. This involves documentation, bug fixing, testing.

Openname : Request for Bounty donation / Student project assistance

Tip the Official FTC Bouny Jar : 6p8u3wtct7uxRGmvWr2xvPxqRzbpbcd82A

The Feathercoin - Nameview - (Opennames DNS) experimental facility is now looking for some testing and documentation work. There has been no response for 5 months so we are now asking for Bounty contributions to do that work.

Feathercoin Admin / Devs are looking to support a profesional developer to spec and complete opennames facility and document it’s operation for FTC version 0.9.6.3, such that it can be easily pulled into version 0.13.x of Feathercoin.

The worked would be based in the FTC 0.9.6.x maintenance “Team”. This involves documentation, bug fixing, testing.

Feathercoin developments and testing : Request for Bounty donations / developer or software builder / assistance

Tip the Official FTC Bouny Jar : 6p8u3wtct7uxRGmvWr2xvPxqRzbpbcd82A

The Feathercoin - Nameview - (Opennames DNS) experimental facility requires a programming review.

Issue : Work was not completed on the opennames bounty. The opennames code has not been pulled into release version fully from the development version or tested.

Requirements : review the difference between working version of opennames and current version 0.9.6.2.1, find the status, compare commits, build and test source code, with full instruction.
