New Ixcoin fork -> I0coin

[markm]

I0Coin is not dead, but when difficulty gets low exchanges don't want to take the risk of doublespends and such.

Pretty much all the recently launched coins probably have too low difficulty to be secure too or will have shortly so probably once the exchanges have sucked all the juice they can get out of the pump and dum "greater fool theory" instant scam technique the launches are designed to do they'll drift into the background like others before them to be mined quietly by CPU miners for months or years until maybe someone put merged mining into them so they can share Litecoin's hash power to try to get enough difficulty to seem an acceptable riisk again to get back onto the exchanges. (Maybe just for another quick pump and dump then drop them again, unless merged mining does eventually turn out to work.)

this coin is dead due to the numerous memleaks

[zero3112]

I guess i don't get why Ixcoin made it but not I0coin?

[markm]

It definitely needs new code.

It tends to die every day or two due to boost doing an assert about the failure of a DNS lookup.

I started it yesterday on another server and had to restart it twice ... and oops, now again:

Code:

************************
EXCEPTION: St9bad_alloc
std::bad_alloc
i0coin in ProcessMessage()



************************
EXCEPTION: St9bad_alloc
std::bad_alloc
i0coin in ProcessMessage()



************************
EXCEPTION: St9bad_alloc
std::bad_alloc
i0coin in ThreadMessageHandler()

terminate called after throwing an instance of 'std::bad_alloc'
  what():  std::bad_alloc

I don't know what bad_alloc is really about, it is on a 24 gigs of RAM server, the other server is only 16 gigs and didn't behave like this.

Basically all the merged mined coins all need a code update though. Some day in the not too too distant future some stable new version of bitcoin (maybe 8.2 ?) needs to have the merged mining patches applied to make a repo that each merged mined coin can then work from to update itself.

In the meantime just restarting i0coin when it dies from the DNS lookup seems to work once it has the blockchain; this new install of it with the alloc problem maybe has never even gotten the blockchain yet or maybe the blockchain got corrupted when it died making it die over and over or something,

the code does a DNS lookup which fails, afterwards it trys to connect to the <nonexistend-resolved-ip> and therefore crashes. thats just 1 thing of uglyness, there are tons of memleaks too

[markm]

All of that should go away once someone cleanly applies the merged mining patches to a stable version of bitcoin so all the merged mined coins have one common codebase to update themselves to/with.

Is this coin currently mined by some people?

Yes but they come and go a lot because the daemon tends to die every day or two.

Is this a new trend? trying to have as many altcoins in the front page at once? Should I go revive all the old solidcoin, tenebrix and fairbrix [ann]s?

Sure, if you like.

I'm trying to do merged mining, but I can't even get I0coin to bootstrap.  It starts with 1 connection, then drops to 0.  Is I0coin dead?

It was dead once and was revived and there were merged mining and after that basically disappear from view.

i stoped running a public node due to high memory problem. if this is fixed il happily run a public node again.

I am hoping that both I0Coin and GeistGeld might be a lot more amenable once the "Mergecoin" repo is ready and all the merged mined coins use it to update themselves to recent bitcoin code.

After using leveldb in bitcoin, the thrashing my disk took bootstrapping all the merged mining chains was embarrassing.

[Hazard]

I'm currently in the process of fixing the memory leak / various other issues and reviving i0coin.

Stay tuned.

[jackjack]

Are you really making me go through my old HDDs to find my i0coin wallets? (which were surely empty btw)

this wont fix i0coin, i0coin has a huge amount of memleaks...

[markm]

Yes it will, because those memleaks are not in bitcoin nor in the merged mining patches.

They are due to some stupid pointless garbage hack or other, or even just a typo or something, in I0Coin, if they exist at all.

All that I0Coin itself really is is a name, a magic handshake bytes set, an IRC channel or collection of IRC channels, a couple of default ports, a difficulty adjustment routine, a block number at which merged mining started, and a block subsidy schedule.

So we take a fully working nice up to date merged mined coin, and change the name, ports, IRC channel, etc etc and presto,a new incarnation of I0Coin but this time without putting stupid memleaks crap into it nor stupid DNS lookup crap into it nor any other useless or damaging crap into it.

However, it might still need shitloads of memory, because even the latest bitcoin code keeps all unspent outputs in RAM I think, and I0Coin likely has a massive number of tiny unspent outputs thanks to a period in which someone was spamming it with "dust" transactions.
