Once it completes, i will begin to (attempt) to add in automated checkpointing and prepare for fork number 3

Ahmed

Looking like the daemon will sync the full chain.

Managed to get the first hard fork. block 51K now,

TxId: 788493e91b31f89173c33cb721502ad7460fc9879e1947c579e76cfe0f4e308c
TxId: 603f74217a21ed5af526aa4a94cae8a3f1492caa0f89c36d28296e8466ce2734

Total: .0506 BTC

What else can be done to harden TiPS against attack?  I'm not stuck on POS/POW, but we need to do something...

Got the first copy of the new TIPS daemon running, only on block 86 just now, with only one node. But will update here as it proceeds further

Thanks for coming to rescue Ahmed, I do much appreciate your offer.

Here is the address for donations:

If you send a donation post your txid here. I'll confirm it with an updated donator list.

I really hope we hear now from the many TIPS users that posted in the past asking for a wallet update. Please let us show Ahmed our appreciation for what he does!

If POS/POW,wallet will bloaed,More pos transactions will add to blockchain,Sometimes it is little hard to run pow/pos wallet.Otherwise pos ,The top 100 owners is risk

I've instead changed to latest LTC due to problems integrating scrypt into bitcoin master.
I'l be keeping Scrypt, i can look into adding automated checkpointing too

I do know the 0.8 BTC isnt guaranteed, I'm willing to wait till its raised if it does but i'll release the source as soon as im done. Main reason for me asking so little is im in a tough spot atm so anything helps

Ahmed

Ahmed,
Very appreciated, the only problem, we can't guarantee the other .8 BTC if not enough people contribute.

Psycodad,
Could you publish an address where we can start depositing BTC?

All,
As for what updates go into the new wallet, I only suggest a minimum of two:
1) Keep Scrypt
2) added security... by whatever means does the job

If better security is obtained by adding a hybrid POS/POW (with minimal POS) then so be it.  I don't even know what a current block is worth because I don't mine it (maybe I should start ), but I would vote to keep the POW reward as is, or tweak it only if there is a significant outcry to change it.
 

At the moment i've started on upgrading TIPS to Bitcoin Master with Scrypt

Ahmed

I think add check point,change the difficulty algo,It is enough for tips
Check point may protect exchange,If deposite confirm numbers higher than check point  interval numbers,The deposite will not confirm.If attacker do not mined 2 check points block,Block will orphan.Otherwise if you check pool ,When many blocks mined,The attacker calculate hashrate and start mining(attack),Made all blocks orphan,Add check point,If he want get all blocks,he had to always mining,It is not attack.
Change the difficulty algo,Can increase attack cost.

 

I'll make a deal. Since TIPS is being attacked. I will start work on the coin today, with 0.2 BTC downpayment. and the rest can be paid once the job is done. I should have an upgraded source in the coming week. (maybe later today if i make a good amount of progress)

Ahmed

The only viable defence that we have on the table is adding POS (additional to POW) right now. If somebody knows which part of i.e. the latest litecoin source could help defend against this attack, please tell us. If we do not now what that fix is, it is pointless to update the sources just to find out that TIPS is still vulnerable to the same attack. So if you know about a check or function in i.e. latest litecoin or bitcoin sources that can effectively battle this attack, please let us know!
Elsewise POW/POS is the solution on the table right now that certainly would make the attack harder.



We are talking about POW/POS hybrid, also the POS rewards could be rather low compared to the POW rewards. It is all about the network of honest miners (and stakers) being able to produce a longer valid chain than the attacker in the hidden can. I agree with you that most coins going POS dwindle in value. But given the POS reward is relatively small and the POW reward much higher, it might make a difference. Also the current attack could drive the price down in the long run way more than POS could ever be able to.

Whatever will be done, I would strongly suggest to go for static block rewards with a regular halving, i.e. 40k, halving annually, the POS reward could be 1/8 of the POW reward, just to throw up some figures. The unpredictable total supply is a PITA.

The diff algo is fine IMHO, it deals perfectly fine with multipools jumping on and off but I am open to hear which diff algo would change what exactly with regards to the current situation.

As it looks we now have the following commitments:
psycodad: 0.05BTC
cryptoid: 0.05BTC
smarterhash: 0.1BTC

I think the donators should be able to vote for things like reward structure, halving etc. proportional to their donation. Does that sound fair? (Not that it really matters as I think we will never come close to 1BTC)

The good news is: You don't need a dev to add checkpoints to TIPS, if you look at the source you will see how easy that is.
The bad news is: Checkpoints do not help the slightest. Please read about selfish mining to understand the problem.

If you want a src with newer and more checkpoints, I'll be happy to push my src tree to github. It really syncs faster and the getchainvalue call stops to be a cpu-hog. But that's all about it. Or why do you think a checkpoint in the past can avoid a fork in the future?

I'll contribute .1 btc as long as the coin stays scrypt/pow



and I could get the coin listed on Alcurex.com

perhaps we start a new block chain - with all coins in circulation made worthless.

I think update same as feather coin ,Keep pow and add check point ,It is fine,It will safe for tips.Can you find Dev? I would danate if tips do not change to POS
Bter instigate miner  do the attack,If we can update from block 12900000,The miner and bter will lost tips.

Bter do it,This is why!

Bye Bye

Hello ppl...
I think this coin is turning into a shit coin
2 days here with dead network, I am leaving this coin for a while....
Work with it at your own risk.

I agree. Making a POS coin will put it in the line of 100's of other POS coins. Also, doing a swap is a mess.
