Well, thats what my patch does, switch to straight solidcoin algo after block 14639 (180s/block, diff increase limit, retargeting period 240 blocks), but keep i0s 48 coin/block reward.
-> diff should adjust by /4 after 14639, and at 4096 diff even single-digit Ghps should be able to sustain at least 1-2 blocks/hour or so.
I guess we could just disable the 7-day thing and keep i0s retargeting algo, but then we'd be stuck at diff 16384 for a looooong time.
Why not allowing difficulty to be divided by more than 4?
4 was chosen to avoid huge difficulty change but as we're now changing difficulty far more quicker we can get rid of that limit, or modifying it to 10 or 20

if someone buys them, they have value even if they are nothing more than digital paper weights right now.
but read a page back or two, paper weights might actually turn back into currency soon.
Yes, you are right. Demand sets the price.
But the only way to trade I0coins now is to send your wallet.dat.
This was supposed to be a joke currency and people got too serious about it.
The founder has disappeared. Is I0coins dead?

Yes bitcoin is dead because Satoshi disappeared.

Actually, just realized something... as ix will also switch to 3-min blocks but has 96 coins/block... that's twice our inflation rate... can't have that.
so... either also switch to 96 coins/block (boooring!) or go to 90 seconds/block target while keeping the 48 coin reward.
At 90 sec/block... change retarget to every 120 blocks (= every 3h nominal), keep the *1.1 /4 limit per retarget, change block acceptance rules so blocks can't be more than 5min or so in the future (we still use bitcoins 120min, but we have way more accurate time thanks to integrated NTP...)
And while we're at it, go to diff 256 instead of 4096 after block 14639.
"special" enough?

sounds good on paper, at difficulty of 256, it's going to lure a small number miners to get in on this.
wish we can test it out in someway, but this thing might actually turn out to be an improved version of solidcoin after all.
we'll just have to wait and see.

Fine with me.. can you tell me the code to change and I'll do it.. or maybe there's a way to add you to the project.... I'm still working on getting this damn thing to compile ( worked on the prereqs this morning before life happened and fininishing that up now).

Well, once theres reasonable consensus on what the new algo should be, it's just a matter of changing the constants and finding a suck... masochi... kind soul to build binaries.
Probably not a too good idea to open a exchange back up before "everyone" switched and the network gets at least a few dozen Ghps.
Yeah, I'll enable the exchange once it's been running for a bit and seems to be working ok. I'll update my pool with the new code though to help move it along.

So can we actually mine IOcoin yet?  I didn't want to read all through the pages, and there is nothing about it in the OP.

Firstly https://i0exchange.bitparking.com/ doesn't seem to work any more (after you login it fails)

Secondly, why on earth are people hacking with the code other than to fix the current problems?

Seriously, just use that patch, make a new one and we'll be done.

Copying some other coin ideas and agreeing coz one person posted a comment here on the forum is not a good excuse to be causing more problems
Every other coin who has been making changes keeps screwing up - so don't follow in their footsteps and just fix the current problem.

Because the entire network is down and now is the time to fix it (ie no one has published working binaries yet which everyone will need to upgrade too).   Either way these were trivial changes.  Now back to getting this windows binary compiling (I suspect linux users probabaly can easily rebuild and restart thier nodes anytime they wish and will once some people confirm they are up and generating blocks again).

Unless someone posts a quick way to reset the difficulty target for restart in the code.. the probabbaly is the last change (unless someone else takes the reigns and makes thier own forks).

The NTP code was broken in the original release. It would cause i0coind to hang if the NTP server didn't respond. It'd be good if that can be fixed. I disabled the NTP code on my systems otherwise it was too reliable.
