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

... checkpoints ...

I think the best option is that each client could create checkpoints itself for blocks old enough. In this context, all the files in ~/.bitmonero or %APPDATA%/bitmonero should probably self-signed by the client on exit. Clients could generate their own keys but that opens up other problems.

[infofront]

Is it plausible to make clients checkpoint themselves regularly? This would require the checkpoints to be saved in some external file that is integrity-verifiable.

Are we going to have nightly build of the wallet file? That is quite inconvenient.

Man up solider!

I do not know how it works
the blockchain
so I write what I think

if I understand correctly
there are master nodes
servers that are managed by the dev team
with bitmonerod above

I understand it a timewarp attack
should be a fork of blockchain
in practice two blockchain at the same time
that's right?
the only problem that would
would double spending
or are there others?

you could not put in the code
that whenever bitmonerod download a new block
the comparisons with blocks of all the master node
if there are two different blocks
type 5 master node with a block
and 3 with a different block
"one of the two would be the fork"

wins the block that is
on more
master node
and then automatically the client
who understands that its not the block that won
auto erase the blockchain
and download
once again
the blockchain
all lead to eliminate the fork
would remain only a blockchain
it would eliminate the problem instantly
double spending

one thing I did not understand
when there is this attack
occurs against a master node?
or a normal node
if no
you can enter in the source code
that the only blockchain exact
is present in the master node


if it brings other problems this type of attack
In addition to double spending
you could explain it?
thanks

OK, I'm thoroughly confused. But I do know that if XMR survives this thorough thrashing, it will rise like a Pheonix. I commend those who would protect the ring signatures from the time warp.

At least use bold text

It can literally become a war of attrition; however if the defence is in the process of developing a permanent fix then time is on the side of the defence. I compiled bitmonerod 4x over the last 24 hours on different computers.  

And thanks to whoever updated the makefile with the release-static target, as now I can just pull and build once on my main mac, and then copy the bitmonerod file around to my other macs that aren't setup to build but can still solo mine.

That was me, I got frustrated with manually building static binaries...it's a pleasure:)

temporary security precaution

Edit: never mind, seems this isn't to do with the ongoing attack threat and the devs are already on top of it.

how long temporary security precaution？

I've never mined any coin in my life. I am interested in mining Monero. I run Ubuntu. Is there an easy/straightforward guide on how i can set this up?

[ArticMine]

Hi folk,

I suspect some potential problem, so i would like to ask to contact me every exchange that trade CN (especially Polo, Bittrex and Bter).
If someone is in touch with exchange operators, please let them know.

X-posted from BBR thread. Seems an attack against Cryptonote coins may actually be underway?

Is there a link to actual post where crypto_zoidberg posted this?

The initial announcement was for 24 hours. We're waiting for the developers to post more details if there's anything going on that would require it to be prolonged.

Welcome, and let me point you to http://monero.cc/getting-started/index.html

Depending on your setup, make sure to read the OP and look for a list of miners. You might have to follow their threads to get more information about how to compile, run, configure them from their own threads (if applicable).

Plus open checkpoints evaluated at runtime allow us to disappear off the face of the earth and a new group could still deliver checkpoints (ie. a reduction in centralisation).

The only plausible way for someone else to take over if we disappear off the face of the earth would be to also take over maintaining the software, which means they could change any public key used to verify a signature, if it were done that way.

The idea that the existing software can continue to run indefinitely and decentralized without being updated is totally implausible.

Point. So then the checkpoints.json thing is a convenience tool more than anything else.

In any case I agree with your point that it doesn't need to be signed, especially if blockchain.bin is not signed.
