General Discussion / Tx hijack to modify output

« on: December 24, 2013, 09:33:32 am »

I probably should have asked the question somewhere else, but I feel people here may also want to help me understand this little tech-detail.

I was wondering the whole afternoon today whether it's possible for a peer to change transaction outputs (so all money goes to a middleman address) before relaying the modified version of the transaction to the network? I don't see any mechanism to guarantee the integrity of transactions. This seems to be a problem especially when a client connects just to a couple of peers.

BitShares PTS / Wallet got corrupted

« on: December 21, 2013, 02:03:54 pm »

I really need help now, especially from 3I engineers.

For some reason, my original wallet (wallet1) only shows 2 addresses, but their balance doesn't add up. So I think maybe there are a third 'change address'. And yes, I verified by looking into the transaction information online (btsblock.com). So I decided to aggregate all balance into one of the 2 address shown.

What I did is to quit the client, move my wallet.dat file into another place (wallet1_backup), restart client, copy the new address (Addr1) in the new wallet (wallet2), then switch back to wallet1(by "cp wallet_backup wallet.dat"), transferred all my PTS (~1000) into the new address. Then I probably did something very stupid. I just "mv wallet2_backup wallet.dat" WHILE the client is still open. Then when I quit the client, I got "wallet.dat corrupt, salvage failed", and I got something like wallet.1387632779.bak.

After I restarted the client, I found I have a fresh new address Addr2 which is not the one I sent all my PTS to.

Is there a way I can restore wallet.1387632779.bak somehow? I eagerly wait for help from the community.

我们中很多对PTS都很期待，不知道有没有3I中国的员工，可以组织一下大家的聚会。

General Discussion / Questions regarding "PTS VC cookbook"

« on: December 05, 2013, 08:21:13 am »

hi, bytemaster,
I read the December news letter and I'm not sure I understand how DACs will be funded. You said the process is like the following

Quote

1. New DAC ideas are already under discussion on the forum, pick one or invent your own.
2. Announce you are developing a DAC and publish an Unsolicited Proposal on the forum.
3. Publish a PTS “Angel Wallet” address where we can bid for allocated shares in your DAC.
4. If the response is good, fund development by selling the ProtoShares in the Angel Wallet.
5. When your DAC is ready, launch it honoring all block-chain recorded deposits to the Angel
Wallet address according to the social contract you defined in your Unsolicited Proposal.

I'm ok with the first 2 bullets, but I do have questions regarding the rest:

for #3, the Angel Wallet is used to receive funding from investors? Who'll do the bidding, the developers or the funders?
for #4, after selling funding PTS, people can have fiat currency to support their project development, so these PTS are then gone, how does those PTS affect the share-structure of the DAC
for #5, I'm totally confused.

I believe an example would make it much easier to understand. Thank you and look forward to making a contribution to the DAC idea.

BTW, I have engineering background but lack experience in virtual currency development.
