Hi all,

Can one of you tell me how to backup my wallet in a secure manner ?
Is backing up the wallet folder enough or is backing up the seed enough ?
What's the best practice according to you guys.


I want to store everything offline preferrably on an encrypted memory stick.

What are your recommendations.

Thanks.

The good thing about Qora is that everything is stored on Blockchain, so nothing will ever be lost, and no backup is needed. As vbcs has already mentioned, all you need is the "seed" and the "password" that go along with it, then you will be able to recover all your wallets & accounts on any computer/device you wish.  Smiley

PS: You can do an experiment yourself, on a 2nd computer, download the qora client, enter your seed, and enter the number of wallets you had created (all your wallets with funds in them), let the client sync... as soon as it finishes syncing, all your funds should be available for your use.  Smiley

Just a note - the password is only used to encrypt the local wallet folder so you dont have to keep it. When restoring from seed you can choose whatever password you like.

You only have to keep the master seed somewhere safe. Maybe on a piece of paper.

You can get the master seed from there: http://127.0.0.1:9085/wallet/seed

Re: S7 Many URLS of Pool in Miner Status
by

on 10/03/2016, 16:01:55 UTC
When you install S7 miner without a firewall, router or something you should at least:
1. Change the UI password
2. Change the ssh password
3. Prohibit access to cgminers API (! this will keep out btcpool.loredo.tv or any other hack)

1. Change the UI password




2. Change the ssh password

Connect to S7 using ssh (default pass will be admin or root ):

Code:
ssh root@IP_OF_THE_MINER

Then type:

Code:
passwd

Now enter you new ssh password

3. Prohibit access to cgminers API

from ssh command line type:

Code:
vi /config/cgminer.conf

Modify line (press i to enable modification in vi ):
"api-allow" : "W:0/0" to

"api-allow" : "W:127.0.0.1"

(press ESC then :x to save the changes)

Then go back to UI and reboot the miner.

Great job Ian. I will code the equivalent AT script and GUI for the AT enabled coins ( qora, burst ).

Each op code (instruction) consumes a fee, so an infinite loop will need "infinite" amount, but even so there is a hardcoded max number of steps (op codes) each AT program could run on each block.

Re: Can NXT be "turing complete"?
by

on 13/08/2015, 14:52:10 UTC
Qora was not the first integrating AT into the core and is not a NXT clone. BURST from the other hand which is a NXT clone ( using different proof, called proof of work ) is the first platform with AT. I am not sure about the latest commits of NXT but for sure it would be very easy to port it from BURST. ( https://github.com/BurstProject/burstcoin/tree/master/src/java/nxt/

Hello
If I initate ACCT, it's possible cancel it? (I try test with 1000 qora)

In which exact step of the process you would like to cancel it?

By initiating an ACCT,  your funds are locked to this ACCT till the expiration or till the ACCT receive the key.
So,  one way to cancel it is to not proceed furthermore with this (after the initiation) and wait for the ACCT to expire. The key will not be revealed to nobody and the funds will be returned back to the initiator.
thanks for explain, how long expiration time?

If we are currently after the expiration block, you will have to send a small tx to the ACCT (with at least 20 qora) to activate it and the funds will be sent back to the creator of the ACCT

1. What's the development ongoing?
2. What's the next big thing in development?

We are currently preparing the next release, so be patient Smiley.

vbcs mentioned he was working on a mixer for qora. Is there a possibility it could be included in the next release?

I will start working on mixer AT which will provide a "layer of anonymity" after the ACCT takes place between BURST and QORA.
......


That feature will not be in the next release.

Also just to note, that this feature will be based on AT, so there is no need for a "new release" when we have it ready. AT offers smart contracts functionality without the need to update the core or anything else.

Very interesting! I'm trying to wrap my head around this. I see a potential security issue with the "refund timeouts". What if Alice post her tx just before the timeout elapses, resulting in Bob never get the chance to receive his BURST? Could you elaborate on that?

Bob's AT must have have less length (expiration) than Alice's AT.So in case Alice sends the TX with the key to Bob's AT just before the expiration, Bob will have time to send the key to Alice's AT afterwards.

Can this be enforced by the AT code or must the trade participants agree on the timeouts?

No it cannot be enforced by the AT code itself as the AT on one side is not aware of the other AT. When user A initiates the ACCT then user B can see the timeout and use a proper one when creating the response ACCT.

Hi qora team. What about new wallet with AT entegrated ? We are close ?

Hey, AT is almost done and doing tests these days. It was delayed due to the need of transactions with messages, which QORA did not had, so I had to implement also such functionality. So with the new qora version, you will also be able to send message txs.

I will speak on behalf the AT smart engine that is currently live on burst coin. No you cannot infect the host pc with virus using AT contracts. But for sure someone can create an AT contract that says it does x but it does y and you end up loosing money if you send coins to the AT, but at least anyone can check the code the AT is executing.

hi vbcs...
page downloaded and tested..
i have a request...

it is possible to add a column like this:
CountDown

simply put a timer indicating how far it is the conclusion of the current round in DAYS-HH-MM-SS

I do not know if it is feasible but it would be helpful!

thanx again!

We could put normal timestamps, but they would be estimations. For example the average block time in burst is around 4 minutes. So when the page says ends in 5000 blocks that's about 1250min almost one day, but that figure is just an estimation based on the average block time.

Perhaps @vbcs might post a nicer version for you that was created using AT Assembler (which has variable *names* and *labels* rather than just addresses as yes I realise that the above is more than a little hard to decipher).

We are working on the idea of some quicker random games of chance and will be sure to let people know when we have a simple example that they can study (we might perhaps make a simple "highest random value wins" for two consecutive players).

One limitation that AT hosts do have is how quickly they can generate "random" data (on Burst that is currently set at 14 blocks from memory) so you could have a dice kind of game but it won't be "instant" (the same AT could work much faster on a blockchain that can produce entropy quicker).


nice to hear about "AT" lottery game!!!
CIYAM,
can you post a link with some how-to play???

many thanks!!!

To participate to the lottery you need to download and run burstcoin. Then follow the instructions which are published here:
https://bitcointalk.org/index.php?topic=731923.msg10254497#msg10254497

i just installed the html file to use lottery!!!

can you explain what stand for:
   - Current best ticket
   - Total amount
   - Next draw


thanks...




In this lottery use case the highest ticket wins the total amount gathered. So the total amount is the total amount the lottery has gathered till now. When you purchase a ticket, that ticket is compared to the current best ticket and if it is greater then your ticket becomes the best ticket. The payout will occur when the lottery runs after the block height defined in next draw.

I am planning to deploy more Lottery cases, where you are not aware of the tickets until is time for drawing the winner or "heads up" cases (where the lottery waits for 2 participants and then decides the winner).
