Hey everyone,

What security measures do you recommend for your cold storage keys. I was thinking more about measures to prevent hacking/theft of the keys. Should i be paranoid to the point of creating the wallet in an air gap and never look into it until I need it? (Lets not go into the "Ruiu says badBIOS leaps air gaps" territory).

Regarding backup I'm doing the _strongly encrypt your files and stored them in offline and online sources and don't forget the deterministic seed_ routine. If anyone as further thoughts on backup that would be appreciated also.


Remember, rockets are old school. We are going to the moon in a space elevator. Keep calm and get some moar.

Peace!

My suggestion is as follows:

1. Take any machine you have lying around, even your normal workstation. You may find it easier to use an older computer that has no wifi or bluetooth if you're particularly paranoid.
2. Create a Linux or Windows bootable disk, and make sure you have the Monero binaries on the same disk or on a second disk (for Linux make sure you have also downloaded copies of the dependencies you will need, libboost1.55 and miniupnpc for instance).
3. Disconnect the network and/or Internet cables from your machine, physically remove the wifi card or switch the wifi/bluetooth off on a laptop if possible.
4. Boot into your bootable OS, install the dependencies if necessary.
5. Copy the Monero binaries to to a RAM disk (/dev/shm in Linux, Windows bootable ISOs normally have a Z: drive or something)
6. Don't run the Monero daemon. Instead, using the command line, use simplewallet to create a new wallet.
7. When prompted for a name, give it any name, it doesn't really matter.
8. When prompted for a password, type in like 50 - 100 random characters. Don't worry that you don't know the password, just make it LONG.
9. Write down (on paper) your 24 word mnemonic seed.
10. Write down (on your phone, on paper, on another computer, wherever you want) your address and view key.
11. Switch off the computer, remove the battery if there is one, and leave it physically off for a few hours.

There you go - the wallet you've created was created in RAM, and the digital files are now lost forever. If some magical hacker manages to somehow get the data, they will lack the long password to open it. If you need to receive payments, you have the address, and you have the view key if needed. If you need access to it, you have your 24 word seed, and you can now write out several copies of it so that you have an offsite copy (eg. a bank deposit box). Due to the nature of the key you can write it as part of something else - eg. write a fake love letter to your wife so that the 24 words on the left hand side are your key or whatever. Then write a bunch of extra love letters. That way, if your deposit box is ever discovered, it'll be disregarded as unimportant love letters.

Is there a website/formula where I can input my machines details to see if it is worth mining Monero?



You can calculate it in the irc channel of moreno. #moreno @ freenode server. Command is !calc x, where x = H/s. Please correct me if I'm wrong.

There is a spreadsheet with some configurations (CPU and GPU are in different tabs) and it gives you an idea of the hash rate of your machine: https://docs.google.com/spreadsheets/d/1MI-ic0Os25hgGUImW54sUIjZY_pUNQNa_W8Se5pRGBs/edit#gid=0. Then you could use the two monero freenode bots (monerobot and monerogirl): "/msg monerobot !calc 100" or "/msg monerogirl !calc 100" (replace 100 with your hashrate). The two bots will give you slightly different approximations of what you should get with your hash rate.

Difficulty went up by 40% today. Unreal.

New GPU miner or botnet ?

EDIT : ...and its still increasing! 43% increase since this morning....

The natural cycle.
  • coin is advertised as cpu only
  • amd cards kick in. sometimes, nvidia even too, but not always
    you are here
  • first calculations wander on an fpga device outside of the mainboard
  • asic chips replace that
  • better asic chips get released
  • (to be continued)
at every step you are advised to firmly believe the next one beeing technically impossible

FPGAs are utterly slow on memory hard Stuff, take a look at scrypt and an FPGA with enough Logic Cells to fit the PoW on is expensive.
So like for Scrypt we will prolly see ASICs on the Market directly, FPGAs aren´t suitable for that from a cost/speed ratio.

There are tons of GPU miners outside, mining Darkcoin, Vertcoin or whatever, why do you think a lousy 2 Mhash increase (we were already at 20+mhash before) in hashrate involves "magic" Wink?
A single big GPU farm could do that.

primer- how much was hashrate this morning if now is 43 % higher?


 I know in last maybe 2 weeks was from 1.8-2 MH/s.


As was seen in last 3 months hash rate steadily raise when price is steady, when price fall it is steady, if price fall a lot, can even decrease tiny bit. When price raise, hash rate boost.

Eizh,

Nice work, looks awesome.

Is there a list of planned features available yet for this GUI?

I recommend watching the first 17 mins of the chat. This is not a mock-up - it's a live run of the code inside Qt creator so fluffypony goes through the functionality. Video link: https://www.youtube.com/watch?v=LlTDS3iCqRY

Basic overview:

The fully expanded account manager is intended for power users. There's a miniaturization button that takes us to a Bitcoin-style simplified interface (image 14 in the set I linked) where all you can do is send funds.

The transaction history can be searched/sorted by a lot of parameters including date ranges, address/names, amounts, payment IDs, etc. There's a slider to set the mixin level. You can collapse the Twitter/News bar if that annoys you. A wizard (for the first time it's launched) is in progress.

International translations will be crowdsourced to the community. Mining is not yet functional but the intention is to have it going in the background, helping secure the network and earning 'interest' for the user. You can opt out if wanted.
