Thanks, merged, signed, and pushed.

Addresses generated earlier are still totally valid of course, and can be restored with simplewallet.


Hi Guys:

Sorry I was away from this thread for a while (and I missed posting in the "leet page" too... dammit.  Oh well LOL)

Anyway, so, I am to understand that that weirdness I posted *was* an actual bug in the offline address generator? 

And now it's updated so's things *should* work the way I was expecting them to work now?  Yes?

If so, I'll try it ASAP and see, and post back any results (or more weirdness) here.

Summary: What I'm really trying to do here is to be just a normal simple end-user of Monero using the most simple and easy available tools or methods as possible.

Read: that means NOT actually running the "difficult" command line only Monero program  LOL

Basically I want to be a Monero supporter, buy and hodl some now from the exchanges (vs mine it) but I don't want to trust keeping my coins on the exchange. 

So I want to be able to make secure cold storage offline address for sending the coins to from Poloniex, BUT at the same time wanna be reasonably sure I can get the Monero BACK under my control again, to either send 'em back to Polo or otherwise move/spend 'em sometime "soon" if necessary, again using only currently available SIMPLE tools and methods.

Unless I'm missing something, this means basically MyMonero web wallet for the near future, unless and until some day (soon?) the official Monero GUI will actually appear (hope hope?)

SO: long story short, what I was thinking should hopefully work smoothly would be:

1. Buy XMR on Poloniex
2. Run Moo's program on offline secure computer
3. Get safe/clean Monero address from #2 and save/print mnemonic safely!
4. Send Monero out of Polo to address from #3 for long-term cold storage
5. Sit tight knowing my Monero is secure Smiley
6. If needed, enter mnemonic key saved from #3 into MyMonero log-in
7. Coins sent to this address at #4 SHOULD BE THERE???
8. If #7 is true (??) send Monero back to Poloniex or whatever...

So IS this how it'd work now?  Any problem or flaw in above?

...do we have any up-to-date community built binaries so I could try out the DB version on my Windows box? I know of the cautionary notes and caveats, just wondering if anyone has published binaries yet.

This is from last week: https://downloads.getmonero.org/monero.win.x64.v0-9-beta.zip

Exercise the appropriate level of care with it being a beta. We've recently found and solved what we hope to be the only major, breaking database issue (that could have caused major issues if we'd tagged prematurely), but that means that prior LMDB sync ups have to be resynced from scratch or imported from a fresh blockchain.raw export.

I've been trying this on my Win7 machine. I managed to blockchain_export ok from my blockchain.bin, but trying to blockchain_import resulted in the following errors:

yeah, the unit tests have killed my builds on recent master.

I think i "fixed" it a week ago by using older head... for instance, checking out a commit circa early august.

so, you'd enter

Code:
git checkout insert-commit-hash-here

replacing that hash with whatever commit you want to try and build.

im currently also testing it using make-release-static 64 (as its been said that the deps are included for this build type).... and it failed.

EDITED TO ADD!

Check your build folder. It seems the primary binaries build fine - i made it to 90% with those errors and then checked the build folder and ./bitmonerod ran like a champ! Well, at least it started to sync with the network.

who needs unit tests?

What's the word on "in the works" XMR exchanges? All the talk a few months ago was about some new fiat/XMR exchanges coming onto the scene. I believe Rpietila was mentioned as involved in at least one. What's the rumpus? The whole polo kyc/aml thing has tempered down, but the market won't properly grow until the speculative aspect has diversified and expanded. Personally I won't go within 10 blocks of an exchange that wants my firstborn just to trade crypto to crypto. So?

My plans haven't changed. The "company" is accumulating 100,000s of XMR and it takes time. I have told all in advance. When this phase is ready, we go to the next phase and open trading. September is still the timeframe.

You can ask the others how they are doing.

But the most important/interesting thing happening with XMR is still Crypto Kingdom.

A Monero/Fiat exchage will be very welcome if as I strongly suspect Bitcoin becomes difficult or impossible to use due to the fixed blocksize and core vs XT issue. By the way my Bitcoin holdings are now down to less than 0.5% of my portfolio.

Edit: September, just in time for the next Bitcoin stress test.

Privacy of course is a needed feature but not the one achieving the mainstream adoption, and bitcoin was never created to be totally anonymous, it's just a coin with a NSA algorithm inside its core, cmon.  Smiley

thats why I refer to Bitcoin as "panopticoin" now Smiley

where is the source code for db branch ? I want to try it out on VM.
Found and compiled, didnt know that it is right in official branch. But I'm curious why can't we have new binaries why the new version is already on the git ?

Devs probably want to get all bugs out before tagging and releasing them.

Pretty much that, but more broadly the "official" (master) branch is really an intermediate development branch. Pull requests are made there from developers' own forks after initial testing so it isn't completely new code but not release quality either. If you want the source for the (old!) official version you have to get it with "git checkout v0.8.8.6". I think the plan is to stop doing this at some point, maybe after the next release. Then there will be a separate development branch, and master will stay at a release.

Thats the reason, once most or all of the child-illnesses are gone there will be release... the new beta for windows is a step forward to that

plan to make confidential transaction was pushed forward on bitcoin. Once bitcoin has that. What are still the benefits of monero / byte / dash ?

I dug up this comment from Fluffypony on reddit particulary for you:

Quote from: Fluffypony
Quote from: random reddit user
anonymity/privacy of this compare to that of ring signatures like those used in cryptonote
It's quite a bit less "anonymous", as it makes no attempt to hide the "metadata". So it hides the transaction amount, but you don't have untraceability (what /u/nullc refers to as "shaping the transaction graph"). The upshot of doing so is that it allows for pruning, which is a good thing. Currently if we had to enable pruning with Monero you'd need to retain the entire txoset (since there is no distinction for utxos, at least not once we've banned mixin 0 transactions) and the entire key image set. Whilst this pruning is quite aggressive, it's nowhere near as aggressive as the pruning available with Bitcoin (and, by extension, with this sidechain). We (nor anyone else) have been unable to come up with a scheme that allows both.

Maybe put differently: this can enhance Bitcoin's privacy, effectively ending the raison d'être for certain altcoins forked from Bitcoin desperately trying to wedge "anonymity" into it, but it cannot magically make Bitcoin fungible. The implementation (as a sidechain) still faces many unique challenges.

That said, I welcome this, and I think anything that can enhance Bitcoin's privacy is advantageous. I'm also a massive fan of the work that andytoshi, gmaxwell, and the Blockstream developers are doing, and I'm sure they will continue to enhance this functionality:)

1. Monero will have default privacy, optional transparency. Bitcoin will have default transparency, optional privacy. The implications are obvious to me.

2. If this were to go mainchain, it would require a hardfork, which is seemingly becoming difficult in that network.

3. specific to monero, there is still the benefits of the adaptive blocksize.

4. specific to monero, the POW is holding strong against silicon advances, thus will be decentralized for the foreseeable future. Bitcoin is dead to me as a decentralized monetary system / payment network. Bitcoin has created something new, yes. But it is not a decentralized ledger system. Right now 4 nodes control 67% of the network. https://blockchain.info/pools?show_adv=no .  Granted, the monero pool distribution is no better at this point, but we are young. https://monerohash.com/#network

4. for monero, the codebase is completely different. Thus, any 0days in bitcoin won't transfer to Monero.

the current XT debate shows that it is nearly impossible to change bitcoin in any way.
if a sidechain implements some kind of mixing it has the problem that it needs much usage to be really anon.

so atm i dont see a way that bitcoin will have real fungibility and anonymity.
