[XMR] Monero - A secure, private, untraceable cryptocurrency

[5w00p]

Monero as a Bitcoin sidechain is like bolting a Ferrari to a Humvee.

Each has its place and purpose, so why try and combine them?

Bitcoin fungibility attacked: http://www.reddit.com/r/Bitcoin/comments/2yvy6b/a_regulatory_compliance_service_is_sybil/

Good read
http://insidebitcoins.com/news/someone-may-be-deanonymizing-your-bitcoin-transactions/30759

Also the term fungibility has been thrown around alot and here is a great explanation in regards to v-currency.

Hi,

On monero.crypto-pool.fr we discovered a flaw that affect the pool-code.
Someone could be stealing a big amount of hashrate for his profit.
As usual, my friend perl(btctalk)/onishin(irc) found a fix that will
be shared with all pool admins.

I wanted the users to know what's going on.
Go on IRC #monero-pools at 13:00 (1:00 P.M. GMT) for details.

Thanks,

Is it possible that this bug has already been utilized by someone?

I would say yes, After a week mining there I received dust and gave up. This was over 6 months back. I was thinking it was the pool owners but guess I was wrong. I'm pretty sure I mentioned it on the board somewhere but was told the pool was was really unlucky and it would even out eventually. This was when I was just mining for profit and didn't know a thing about XMR. IIRC I mined about .7 XMR after a week on 5 R9-270's and a 1600T.

I have been mining on crypto-pool.fr for months upon months. You should be careful not to shoot the messenger here. They found the bug and fixed it, and they are one of the most productive pools in existence.

You are entitled to your opinion and you can mine where you like, but I have been pleased with their pool and support work ethic.  I have pointed my miners there consistently, having tried several other pools from time to time.

All known duplicate share vulnerabilities fixed on my pool.

Issue was similar to exposed by me several months ago. Someone submitted duplicate shares using nonce validation vulnerability, thanks to onishin for bug report. Stats of spotted attacker were immediately flushed to prevent round payouts to his addresses. Sorry for any inconvenience.

Have a good time.

No one can stop xmr community on our way to the moon.

Well done on the pool fixes, can only imagine how much a nefarious character could have been gaining if the vulnerability has been there since the beginning. Scary stuff and a shame for all the honest miners out there.

Not trying to shoot the messenger, just pointing out that yes is the answer and what my experience was there. These are the facts and it would explain why what happened to me happened. If anything it exonerates the Pool owners in my mind. I looked at the pools percentage and figured they must be doing something right at the time but was not willing to run my rigs at that loss and switched coins. In retrospect I should have investigated more deeply as if I had I more than likely would hove "Found" this coin earlier and would be the better off for it right now. IIRC I switched back to Doge and that was a utter waste then to rental and I eventually stopped mining altogether rather than buying new gear.

Others have talked about Monero's technology being implemented as a sidechain of the Bitcoin blockchain. Is that feasible?

It's feasible, but for now I see side chains as not much more relevant than any other alt-coin exchange. The changes that would need to be implemented in BTC are not trivial nor have they even been presented as pull requests - aka it's vaporware, for now. The only way that side chains get implemented today are by federated servers which hold the private keys to all BTC 'locked' in multi-sig transactions in the main chain, representing value in the side chain.

While I do have a lot of respect for the Blockstream devs, it's just too soon to know if they'll be able to implement anything stronger than a mechanism requiring full trust in Blockstream Inc's federated servers. In this way, it's no different than Poloniex.

TLDR; Not a concern in the next few years.

Bump. Please vote. We've always done really well on these polls. This one not so much.

There's also no way to keep Bitcoin out of our blockchain if we implement sidechains... We could transfer Bitcoin into the XMR sidechain as a token, then transfer it back to the BTC main chain (as long as we switch to a fast-to-verify hashing algorithm).

Conversely, there's no way to stop us from storing XMR on the BTC main chain as a token once sidechains are implemented too. In the future I think we'll see all cryptocurrency types traded in a distributed fashion on many different chains, with their tokens representing "equity" in the developing parties of the respective blockchains.

This would certainly make decentralized exchanges easier to implement, would it not?

Trivial, even... you'd just port CounterParty or CoinPrism.

Then every blockchain simply becomes an exchange with varying liquidity and security. I think this might be the actual long term scalability solution.

Why use a Bitcoin sidechain when you can use Monero and enjoy privacy at protocol level?

ask yourself this.

If you need to pay something with Bitcoin just use xmr.to.

For the long term success of xmr.to, or any future competitors to it, they need to charge a reasonable fee for their service. People are willing to pay for anonymity. What they are doing right now is honorable but not sustainable.

I seriously doubt what you experienced 6 months ago was this pool exploit, Heuristic.

It is however, a very opportunistic time to point out what a whizbang super sleuth you are.

So if you are admitting your guilt I figure that I am owed 732 XMR. Please pay up!

I never said it was, I have no clue why and when I asked then I was told there was no way and It was luck. Maybe it was maybe not I still have no clue. All I know is it was possible and I didn't know that before.

It's funny that you are doing to me what you are accusing me of doing, shooting the messenger.



Oh and unless you haven't noticed my monikor is Hueristic. But you were close it actually is a Pun on heuristics.

In case you forget in the future here is a ditty so you can sound it out.

I've started to work on a cross-platform GUI about a month ago. This task involves code rewriting from scratch, thus, improving the performance and reliability of my client. More information coming soon...

Put your dogs on leashes, it looks sloppy and pathetic the constant trolling of the DRK/DASH thread. Let each coin stand on their own merits and the market will ultimately decide.

I watch DRK threads...  I don't know 90% of the people trolling.

[Furio]

I do think monero has a very solid basis, yet it remains so that allmost anything can be implemented in the blockchain. What protocol will win, who knows, curious to see which of the "dark" coins will survive and thrive.

In that DASH thread they consider any statement or position which questions DASH going to the moon as trolling.  What a big circle jerk going on over there.
