The chains tries to resync still. May need  to go a step furthe

I deleted the blockchain, and peers.dat and added banscore=1. That seems to have fixed it

lol, hydro has no idea how to fix it? check alphacoin's code, I guess it also fixed in GLD Grin Grin Grin

I knew about the magic numbers, and was fumbling through, trying to fix it, but, short on time, so, I decided to do the next best thing, pay for a solution Wink

Devised a few extra steps, to get it working properly, but, Muddafudda, your client is working great.
Due to time constraints, I'll go with the quick, temporary fix, for now. I will intigrate the more perm solution, in a couple weeks, when my schedule settles down.
How ever you guys want to do the bounty, letme know, I'll pay it out

Yup, that pchmessagestart seems to get forgotten quite often, it actually defines the protocol message starts. Its also written in blockchain etc as block separator

blk0001.dat is not part of the blockchain, it's only one of the files that one client, bitcoin-qt, uses to store it
The blockchain doesn't have such things as block delimiters, it's only a list of blocks

btw, muddafudda, im willing to offer 50/50 regardless of what hydroponica decides Wink

Oh poo.

Good to see other ways to deal with it. Yes my option would need to be monitored in each update.
But the chance of litecoin going above 80003 in the near future is unlikely.

I change the public key when compiling new coins but was unsure whether there would be conflict. Good to know without trying:)

Reason for the crosstalk actually is in the "magicnumber"  
Code:
unsigned char pchMessageStart[4] = { 0xfb, 0xc0, 0xb6, 0xdb };
You need to change this, but beware new and old clients cannot talk together after the change. so its compulsory update. ofc you can do it with changeover at nTime of nHeight but its lil more complicated.


meanwhile to prevent connections from litecoin network add this to line 2517 (main.cpp)
Code:
       if (pfrom->nStartingHeight > (Checkpoints::GetTotalBlocksEstimate() + 100000)){
            printf("pfrom->nStartingHeight > (Checkpoints::GetTotalBlocksEstimate() + 100000)\n");
            pfrom->fDisconnect = true;
            pfrom->Misbehaving(100);
            return false;
        }
This prevents ppl with blockheight with 100k+ compared to latest checkpoint from connecting.

also at main.h line 1589
If you change that 0401.....3a9 to your own publickey, you'll suppress all litecoin warnings + you can actually send warnings of your own.
(Im not totally sure if compressed pubkeys work, getting uncompressed one needs a lil hacking with forks of litecoin 0.6+)
Code:
       if (!key.SetPubKey(ParseHex("040184710fa689ad5023690c80f3a49c8f13f8d45b8c857fbcbc8bc4a8e4d3eb4b10f4d4604fa08dce601aaf0f470216fe1b51850b4acf21b179c45070ac7b03a9"))

muddafudda's code is good, tho problems could arise later if/when litecoin gets upgraded etc...
If you wanna do the magicnumber switchover smoothly pm me later or sommit.

Ill post my GIL address later Wink

NOT PUBLIC RELEASE - HYDRO APPROVAL FIRST

See how this goes.


Upgraded protocol to 60002, limited  versions in protocol to 60003 and lower. Added checkpoint, upgraded version number.Removed Litecoin alert also.

Adding banscore=1 to your .conf can help with this, it won't fix it per se, but it will make the GIL client drop any node that wants to try and synch in a longer chain.

Checkpointing up through the last block available can help too--but until the whole network is upgraded you'll continue to see this.

Last but not least, you might want to change the protocol version number up one or two, that should make the newer clients stop connecting to the older, but not the other way around.

Eventually once everyone's on a newer version, the quibbles should stop.
