[Dev] Develop new core 0.9.3 for feathercoin, together

You’ve already done the p2pool for the core?

Liz mate! I, im speachless…

Danke, Arigato, è°¢è°¢ !

lizhi

Yes, http://block.ftc-c.com , It base new core. P2Pool on http://block.ftc-c.com:19327/static/

Looks awesome!

I would post a screen cap of it but bayimg is down so I have no where i feel ok with uploading images to.

note to self… decentralise bayimg…

Today , I find SX Transaction confirmed on MAIN_NET . pleasantly surprised. five days ago, they are broadcast.

txid=5450cbc71b182a92e626be374c54fe4a5def179c363923fcd982248da7d0058e

txid=dcc0260532025d6d7ecd69cd3cdd8ed9ea58ea4d96669a9e2b83c46e33e058fd

So sx:tx is working?

lizhi

I think so, I started them, but I did not notice. I will broadcast some new SX Transaction, If pool that base 0.9.3 core can find a new block, SX Transaction will recorded in the blockchain. Wait 24 hours

lizhi

one good news : SX transaction can be comfirmed on blockchain.

one bad news : receiver can not get it.

I was checking the possible problems.

Because some code conflict , I’m fixing the ACP issue. I rewrite SetBestChain function, Now checkpointsync has been added to the project.

Over the past 2 days , It work all right. I think core wallet have supported ACP. I will submit code in tonight.

Oh you little beauty!

Really?!

I can’t wait to see this confirmed!

That was a lot quicker then expected!

I’m waiting , if my miner can find a block include SX , successful.

I am sure that this system could be abused if it fell into the wrong hands. Which is why I believe that we need to work on making this solution distributed.

I’ve posted this elsewhere and should post it here. You can enable and disable the checkpointing with enforcecheckpoint true and enforcecheckpoint false.

./feathercoind enforcecheckpoint false
./feathercoind getcheckpoint
{
“synccheckpoint” : “ac9376eb5161c3699ae8492bb23f17e02876d6f5b58dd9767ee137b49ea563c0”,
“height” : 68665,
“timestamp” : 1376803376,
“subscribemode” : “advisory”
}
./feathercoind enforcecheckpoint true
./feathercoind getcheckpoint
{
“synccheckpoint” : “ac9376eb5161c3699ae8492bb23f17e02876d6f5b58dd9767ee137b49ea563c0”,
“height” : 68665,
“timestamp” : 1376803376,
“subscribemode” : “enforce”
}

Now that it looks like Core is almost good to go out, removing ACP is priority number 1.

There’s a few ways about it it seems so lets not panic.

Don’t forget, Worldcoin is using a rebranded form of ACP called WorldShield. - http://www.worldcoinalliance.net/worldshield/

static being the key term here: we are compiled dyanmically. Building on Fedora will tell you so as openssl removes the elliptic curves in Fedora.If we built statically with openssl sources we would not have this issue. As of now, all we have is the daemon, not the wallet client for Linux-es. WE WANT the WALLET. The WALLET is what were after.We need to repack and rebuild everything now. NO, windows is NOT EASY. We should be able to run the code thru mxe(MingGW on linux) to build win32 binaries but we cant.It HAS to be DONE on windows, where Visual Studio is the common element, not MingGW or QT.Someone built for VS once before and this needs to be done again.You can get VS for free (from microsoft) if you look hard enough.

The wallet will come soon for Linux. Compilation works, packaging is in progress, but if a Package for Fedora can be built is open.
