CfB, please describe in detail how to forge a rollback.

Make the decision technically available for those who wish to support that please.

There is not even a vote needed. Forgers can vote by taking action.

+1. We are waiting for instructions to take actions.

Hoping that bter will offer a refund or that the successfully negotiate with the hacker is a waste of time.

There may be other options. Hacker stated he wants btc not nxt. There aren't enough NXT exchanges to cash out.

Hacker just posted a message:

http://www.mynxt.info/blockexplorer/details.php?action=tx&tx=737607765281301757

Message: We can trade these NXT for some bitcoins to make life easier for you, and me.

bter can offer a deal with the hacker as well.

Two cents from me:

1. Reversal could be done by forgers only, not Nxt itself. In the same way BTC pool/pools union having more than 51% of mining power could do blockchain manipulations.

2. Unfortunately we havent' Voting System in production yet. It would helps us a lot in cases like this one.

A possible solution, that I have not seen mentioned:

Someone remove that 50M transaction from the NXT database, instead transfer them to another account that is held by a trusted NXT user (J-Luc, C-f-B, or whatever) so they in turn can give it back to BTER.

Publish this new database file so forgers can download it and replace with their own.

Positive stuff:
+ Only the thief should be affected, all other transactions will be executed.

Negative stuff:
- I guess it will be a hard fork between forgers who don't use modified db file.

There might be better ways of executing it (publish a open source script/executable that removes rows from db instead of a completely new db).

I will never support a total rollback, in the long run, as I believe it will hurt NXT community more than it helps.

Just create a hall of shame thread where you put addresses of all hackers, so that exchanges can implement measures not to accept funds from those addresses. It won't make much sense to steal then. And the hacker could return most of the stolen funds.

Don't write the same thing repeatedly in red.
Also: Don't be silly. It's not possible to perfectly block his addresses. You have to stop asset buying too and DGS transactions.
Mixers and anonymous sending are already in the works.

And consider: If blacklisting works, it's equal or worse to a rollback for all I see. It would be the majority deciding what one person can trade.

Wouldn't this change the checksum of the blocks? The blockchain is specifically designed to prevent stuff like this. The only way to non-obtrusively get rid of it is to undo all the blocks building up to it, then rebuild them

I didn't mean blacklisting on NXT level, I meant blacklisting at exchanges' level, exchanges are perfectly free to choose who they accept as customers, this doesn't make NXT less decentralized.

I am in the early stages of examining NXT. Neither I nor the entity that I represent have any ownership.

In my opinion, you can't roll back this transaction. When Mt Gox went down, it is my opinion that it has made and will make the Bitcoin community MUCH stronger.

I now feel that the US economy would be stronger and a real leader in world markets if the FED had NOT saved AIG and others.

I am very intrigued by NXT. This forum seems to have FED like powers at this stage to turn back the clock (not sure that can really be done), and I think this would be a mistake to save one and not others. Where do you draw the line?

Lin used same password for 90% of his services including his linode account.

I'll be willing to give everything back if there is reward in btc from the profits Lin is making..

Complete lack of security.. same password for everything.

Remove the blocks after the theft and forge another branch where 50M will belong to BTER

b) consider ALL consequences of a rollback! ALL transactions by EVERYONE will be undone!

No, similar case happened when someone exploited crazy fee bug. If the transactions were sent with 24h deadline they'll be included into new blocks.
