[ANN] Slimcoin : Proof of Burn NEW BLOCK GEN, Mineable by low power computer!

[masterOfDisaster]

I had to resync, but now I am stuck at block 111988 ... the block explorer is on block 205177+, so there must be a way ...

I thought the dev has abandoned SLIM,is that true? 

[masterOfDisaster]

I thought the dev has abandoned SLIM,is that true? 

I have not read the complete thread. But as I was recently engaged in a conversation about Slimcoin, I have some links at hand.

That being said it appears that the original dev has needed to shift priorities while still being willing to maintain this project.
Slimcoin might appear quite dead, the subreddit has 7 topics, Slimcoin is not so wow.

But I see things differently.
I think this experiment (Proof of Burn) is still going on for some time (and I like that, because even if Slimcoin might fail, it at least introduced something new).

• Another dev ("a123") has stepped in to work on a fork of the code (latest commit 7 Nov 2014).
• PoS (supposedly the source for the forking trouble) was announced to be removed by a hard fork and finally removed.
• The block chain is being continued: there are nodes and the PoB and PoW processes are running.
• There are stable binaries available for those who don't want to compile.
• The latest source code by "a123" is available.
• There's still the official Slimcoin homepage and another Slimcoin homepage (from "a123").
• There's a blockexplorer (in fact there's even a second).
• There's an exchange trading SLM.
• And in other areas (GPU mining) there's also development. There's already an improved version available!

Except for removing PoS, getting block chain forking trouble under control (as it seems), providing (stable running) binaries for Windows, Linux and RaspberryPi, developing GPU miners, there's not much going on
...reminds me of a quote from Life of Brian

I can't asses the implications of having removed PoS and continuing with PoB/PoS alone
Energy wise (and security wise?) it might have been better to remove PoW and continue with PoB/PoS.
But as PoW is distributing Slimcoins to people who not necessarily own Slimcoins (in difference to PoB and PoS), I welcome this decision.
This might be one of the major reasons for continuing Slimcoin instead of forking it!

I don't know how secure the block chain is.
But if PoB for securing a block chain gets into the focus of somebody (another dev?), it will be hard to overlook Slimcoin for there are no other implementations of continuously running PoB coins (afaik).

PoB has the potential of being a security mechanism for block chains that is very (energy) efficiently working (like PoS).
That alone is reason enough not to loose track of Slimcoin!

Roughly 40,000 SLM is not very impressive. As you see the SLM price is that low you only need to pay 1.4 BTC for 40,000 SLM.
...but that may change. Who knows.

And on the other hand are less than 40,000 SLM available in total (at the moment, 21:40 UTC) for more than 1.4 BTC (sorry for the bad formatting; I'm to lazy to make it look nicely)!

222.132.96.187 seems to be the only peer that is at an odd height, and that could be because it's syncing.

Are you using -listen=no or listen=0 ? The latter is the correct format. (Also note, single dash, not --)

[gjhiggins]

Of the 8 connections visible from here (ADSL broadband chez nous), only one of them is at a significantly different block height:

1. it's not the same IP addy as t'other un
2. seems stuck halfway through syncing (so is probably not a fork).

I've read almost the complete thread. I remember a lot of primer-'s posts talking about an incompetent dev and Slimcoin being a shitcoin. That's what the world needs to know.
Thank you for warning us.
Thank you primer- for sharing your professional attitude with us!

My assessment of Slimcoin is a bit different, though.
I'm aware of the trouble with forks.
I'm aware of the trouble with PoS.

Nevertheless I think that the orginal dev has made a hell of a job implementing a working implementation of Proof of Burn!
That for sure would need more fine tuning.
And some of it was done by a123, e.g. the removal of PoS.
I can say that both the Windows version and the Raspberry version compiled by a123 work fine. Couldn't test the linux version, though (because I have a 32 bit operating system).
The forks seem to be no big problem any more, although the network seems to be quite small.
The security of the block chain is ensured by both the PoB and PoW blocks that have a decent trust value after a123's adjustments.

I want to say something more about PoB, because I got intrigued by it.
It may solve one of the big problems that are inherent with PoS solutions.

In PoS systems with an annual reward it's not important when you mint. You'll get your reward. You might lose compound interest, but you'll get your reward. You are not bound to countinuously contribute to security (unless you are aware that this is necessary to protect the value of your coins.). You don't lose the coinage unless you transfer them.

The PoB approach is somewhat different. After you have burned coins, they start to decay. That happens over time no matter whether or not you mint. If you don't mint after having burned coins, that is a loss, because the coins are gone.
You are incentivized to continuously mint hoping for some minted PoB blocks.

This can lead to a continuous burning and minting.
If very few coins are burned, the difficulty is low and it's worth burning only a little amount of coins to successfully mint PoB blocks (which should have quite high rewards if I got it right that the reward is inversely proportional to the diff).
So there's an incentive to burn coins.
And once they are burned, you need to mint to become compensated by PoB rewards.

That is, dear primer-, something completely different than a shitcoin.
It's a revolutionary approach to secure a block chain energy efficiently with interesting economical attributes!
I'm quite sad that the further development is (temporarily?) ended.

@d5000 if you'd like I can create a snapshot of the block chain and upload it somewhere. I don't know where your trouble comes from. Both the Windows and the raspberry client had no issues downloading the block chain.
I started from a123's snapshot.
Here's my current peerinfo (I've not checked for differences from the last one; I hope there's something helpful in it):

@masterofdisaster: +1 for your post. primer~ is simply trolling. A greater problem is that he probably still owns a pretty large stash of SLM (as he was one of the biggest PoW and PoB miners in SLM's beginnings) and can dump them anytime the price goes up. But very probably his profits would be higher with a more "diplomatic" approach My theory is that he is afraid of a possible success of PoB as an alternative to PoW and PoS.

I've already written that my greatest interest in PoB lies in its "incentive system" and the relation between the number of burnt coins in a given moment and the "price" of the currency units. The hypothesis is that at low prices, people could burn more coins (as they're cheaper) which leads to a smaller supply. That could be a way to stabilize a cryptocurrency price without having to use market pegs like in the case of Nubits or BitUSD. I would like to research this in more depth, but we are still way too small as liquidity in the BTER market is too low and so the number of burnt coins is probably not related to price.

Regarding my resync problem: I am still stuck.

@almightyruler, you are right I was using a incorrect format for -listen and -connect, but with -listen=0 I have the same problem.

I tried using -rescan and -reindex like suggested here but still no luck.

@masterofdisaster: I have updated my peer list again. If you could upload a snapshot newer than block 112000 it would be helpful. I am now trying once more to download the blockchain from zero, will post if there is success.

Sheep everywhere.

PoB is 'broken by design', the number of burnt coins/PoB diff is so high it would take you years to mint 1000SLM if you were to burn them now.

[d5000]

That's not a bug, it's a feature. If PoB diff goes too high, burners will have to accept lower income for some time, until an equilibrium is reached. So the system forces participants to act in a rational and not in an emotion-driven way (making serious calculations and not burning all coins in a kind of rat race), only this way miners can profit.

@masterofdisaster: I see a123's snapshot is from block 126xxx, so it probably will solve my problem. Will post if I have any issues.

PoB diff increases with the number of burnt coins. It does not decrease, ever.

[d5000]

@primer~: No. Burn diff correlates with the number of "effective burnt coins" (nEffectiveBurnCoins). That number takes into account the "burn decay" of every burnt coin. Every burnt coin after 1 year has an "effective burn" value of zero. So if nobody burns more coins from now, in one year nEffectiveBurnCoins will be zero.

Decay rate is too slow, there is no incentive to burn you donkey

I'm out.

[d5000]

Haha, you admitted you were wrong :p

If you want to get out, feel free to do so.

[masterOfDisaster]

I will only start to believe that primer- has left this thread if there is no post from him for at least one year here...
...but maybe d5000 has done the trick.
Now we need only the old dev back or a new dev or maybe a123 continues and this experiment can move on
It would be a pity not to continue with the PoB idea!

[d5000]

Well, perhaps the 40.000 buy is a new dev stepping in ... perhaps he will dump again at ~ 10.000 satoshis, but maybe we have other problems solved

I think the priority for a new dev - or "slimcoin" or "a123" if they come back - would be to follow closely the development of Peercoin 0.5, which will be based on a newer codebase (the BTC 0.6 base of actual SLM is pretty old, there are a lot of useful commands missing) and merge the new peercoin code with SLM.

The other one is the decision how to continue with the distribution model: PoW/PoS/PoB? PoB/PoS? or PoW/PoB?

For me, both PoB/PoS and PoW/PoB have both advantages -  three different block generation algos are a bit too much, I think. PoB/PoS would be "the ultimative green coin" without energy waste, but PoW until now determines the PoB difficulty, so it will be more difficult to replace.
