Bitcoin / Electrum / Re: how to decrypt electrum wallet?

on: November 13, 2013, 09:22:26 AM

You could try creating a new wallet with the same password, then copying the seed between the two wallets and using that. Backup everything before you attempt this though. I have no idea how to otherwise do it.

Bitcoin / Electrum / Re: [Question] The security of disclosing MPK and Gap Limit Security

on: November 13, 2013, 09:21:17 AM

Your MPK exposes your addresses. So anybody with your MPK can view your balance and see where your money went. They won't be able to spend it however. Your MPK already exposes everything regardless of your gap limit. This is a client side setting that won't effect anything besides that. I wouldn't use a gap limit of 9^10th since Electrum will need to check balance for all these addresses to see if any funds came in. I doubt it would work.

Quote from: rbdrbd on November 13, 2013, 01:32:20 AM Newbie question...what's the easiest way to send Mastercoin if I'm using the bitcoin qt client? * I could run mastercoin-adviser.py, but I'm not sure how to craft that transaction it wants me to make, in bitcoin-qt (could probably do it in armory, but I can't import my bitcoin-qt wallet over to armory) * mastercoin advisor is disabled on mastercoin-explorer so I can't make the raw transaction there * pymastercoin is broken up against bitcoin 0.8.3 (some error regarding multisig returned via JSON RPC...can provide more info if needed) * mastercoin-tools ... can't figure out msc-send.py .... * The ruby GUI wallet does not allow for sending of mastercoins it seems (only test mastercoin is available) * The FAQ isn't much help here, beyond what I've tried. So that's 6 dead ends... I will bring creating Simple Sends from the website back and today or tomorrow there should be a wallet release where real transactions are enabled. You got to understand though that I'm responsible for the code and if it ends up sending the wrong amount I will be in a heap of trouble. I want to triple check everything before releasing this.

FYI I'm bringing Mastercoin-explorer down into Maintenance mode. I'm upgrading the backend database and while I could keep the site running while this happens the performance would be subpar and it will start to lag behind. I rather not confuse people when their transactions do not show up.

I believe there is a bounty for a FIAT/MSC exchange. Your software idea sounds like it belongs there. Exchanges need to be fast in order to function so Go might be a good fit

I'm running some intense database migrations overnight so there is large chance Mastercoin-explorer is lagging behind at the moment. Your transaction should show up in due time, if Masterchest has it I'm sure it's fine. Edit: Here you go!

The idea is that you have a normal bitcoin wallet and reserve one of the addresses there as your Mastercoin address. You dump that key

As long as you can sign transactions you can use any client that supports it. The Mastercoin-wallet software just does all this for you so you don't need an other (Bitcoin) client.

Quote from: Bitoy on November 12, 2013, 05:28:27 PM Hi Tachikoma I've updated the parsing (all class A is now "peek and decode") and Master Explorer and MyMastercoins has the same balances (yehey!) Except for one address 15a4XCuWmx2cCQVf8wZK7mqdvj5uwo1vby MM=575 ME=570 It is TX ecb77ee990de29745de949462e1f6e44584c310a0da12c9fbdf86dbe6ffabcfc btw First line of your API there is a null address with balance 5.0 [{"address":null,"balance":"5.0"} Woop! Awesome. As soon as I'm done with my current validation rewrite I will check out this transaction.

BitBoy some of those transactions are wrong at my site as well. You might actually parse them correctly. Quote from: grazcoin on November 12, 2013, 04:04:16 PM Quote from: Tachikoma on November 12, 2013, 12:50:12 PM Guys I need to amend the validation spec a bit. But to do so I need your opinions. Right now Bitboy and I deal differently with addresses. When Mastercoin-explorer displays the addresses for a certain currency_id and an address has not received any transactions for the given currency_id it omits the address from the results. As far as my application is concerned the address does not exist so it can't display it. BitBoy's implementation however returns the address with a zero balance. Which is technically also correct. Anybody has a reason to pick one over the other? I think bitboy's approach is better (same behaviour of blockchain.info). It means that I will have to change my implementation as well. The problem is that I have no clue how I can find something that doesn't exist. I can't supply addresses that I don't know exist. I could query all currencies (there might be a lot in the future) and use data based on that but that would only bloat the verification-api without any real benefit. I still vote to omit addresses that have no transactions for a certain currency_id.

I will join the comparison game whenever my sell offer/accept parsing is done. That's a great tool. Once I finished the code I will put the site online. It should display an overview of all transactions that are parsed differently on all sites, we should all be able to use this.

It was decided that block 255365 was the last block that counts, everything before or in this block counts.

Test Mastercoins are not the same as Mastercoins, they are a separate currency meant for testing. At this moment there is still some discussion on how to interpret the spec which makes sending real transasctions tricky since things might still change. You can sign a transaction but unless you send it nothing will happen. If you send the transaction but don't send the coins your offer will expire based on the time set out in the original selling offer.

That would be an invalid transaction. I've had a night to sleep on it and I'm not sure how much I like it. I still do not like the random chance but changing the procol might be too drastic. Unless somebody really loves it let's drop it.

I'm not even sure I'm 100% behind it, but it would make parsing much more straight forward. The thing I might not have explained enough is that I think this artificial lag should be protocol wide if we would even consider doing it. This would mean that Simple Sends that receive and send coins in the same block would also be invalid if the proper amount of the outgoing coins was not sufficient before this block, etc. Grazcoin, Zathras, Bitboy could you please join the discussion on PR #1 here https://github.com/mastercoin-MSC/spec/pull/1
