http://m-core.org/issues.txt

I'd like to address some concerns raised in the past as well as recently. A short summary:

## Concerns raised by the new PoW/PoS block mining/minting rule (v1.4.4.1)

* Potentially disturbed the way how difficulty was being adjusted
* Block rewards are affected accordingly
* Hashrate calculation needs an adjustment
* PoW block rejection causing less effective blocks mined

## Difficulty adjustment in slow response to the hashrate

## Big Hashrate concerns

## PoW / PoS rule violation

For details check out the link.

The first and foremost, we need a change to the difficulty adjustment algo. The situation has been associated with miners who jump in at low difficulty and mine blocks before the difficulty increases. A block-to-block adjustment should reflect the scene of miners in and out that creates hashrate fluctuations. Importantly, the block reward adjustment itself should be sensitive to difficulty / hashrate variation.  

I'd give an expectation of one month to address the concerns; however, the final release might depend. I will update over the course. For the major concerns and possible approaches are mentioned below.

1) Difficulty adjustment algo as mentioned above

2) The new PoW/PoS generation rule concerns block finding efficiency by some pools

* Reverse the PoW block time to original 3 minutes. The idea of using 4 minutes changed in v1.4.4.1 is to reduce the PoW violation; PoW violation seems to occur anyways unless block time is significantly elongated. Instead, the larger block time reduce the number of PoW blocks and thus less chance hitting on the small-scale pools.

* Mitigating PoW block violations

The initial purpose of the PoW rule is to avoid flash mining that likely causes the forking issue; I believe this isn't that helpful on the forking under the new release. In addition, the new rule helps on the situation that big miners jump in when difficulty is low and mine blocks easily and quickly. I thought about reducing down to one PoS block between PoW blocks; however, this is not enough I believe. There is randomness in blocks at different time (though regulated by difficulty), and possibly blocks come out adjacent to another PoW; even though with reducing two to one PoS block between PoW would still lead to rejecting one portion of PoW. One way to take is to have the PoW rule similar to the PoS rule: multiple PoW blocks (say three) one after another allowed, but no more than four (numbers are example). It should be noted that there is a chance when big miners come along they might mine the allowed blocks, and left those blocks to be rejected to other miners; again this can be in part sorted by well-shaped difficulty adjustment. In either way, mitigating PoW block violations is the way to go from what I can see.

3) Big hashrate miners & fast block reward adjustment

A fast-response difficulty adjustment will facilitate evaluating the difficulty properly and thus the block reward (reward-difficulty dependent to each other). Other than this, block reward adjustment should also take place fast and reflects the hashrate in no time; hashrate would be another parameter to have in place.

Given a better responsive block reward, it won't be necessary to turn off PoW at high network hashrate as we talked a while ago. However, I'd go the turning-off approach at a rare situation, like 5-10 fold increase in the hashrate. We'd be aware disturbance to how PoW operates will get side effects as we've seen.

The coin targets at mining to be available to broad audience and general users. I was aware that there is no way to get done by few people, and would put the way in community and encourage participating in suggestions to make it better. Feel free to suggest.

seems like a good plan and not too aggressive. Will wait for the next upgrade. Cheers

Agree, seems like better balance. Gonna be nice to see it implemented!

I can't d/l the new wallet. I upgraded my router and it's built-in av/firewall by Trend Micro is blocking the d/l saying it is malware.
Is there any other site I can grab the wallet from?

You should only get the wallet from http://m-core.org/download/ for magi, specially if you are using binary.

Some antivirus report wallets and those are false positives.

Yeah - I always used to get that with the sweetspot miner - but just created an exception in my anti virus rules. They are pretty harsh with anything to do with crypto.

I think the Magi is because it uses IRC - some viruses also use IRC to list hosts, so its probably just a catch-all on Trend Mircro

(But seriously, only download from the official link on the OP)

i dont know why people like to use antivirus with a lot of false positives. Stick with proven track record if you want to use antivirus or go no antivirus at all. Bitdefender Nod32 kaspersky norton are some of the proven antiviruses

Summary

Magi (XMG) is a PoW/PoS hybrid coin (mPoW/mPoS). Magi is designed with difficulty dependent mining reward for proof-of-mining (PoW) blocks in order to put network hashrate under a certain limit. Magi at the first time implements a novel proof-of-staking mechanism, to frustrate potential attack through accumulating a large number of coins and offline staking time (read more..). Magi is at the first concentrating on the low cost in maintaining its block system, for example, through cost effective mining devices. To this end, Magi, aiming at fairness, cost effective and energy efficiency, strives for every single effort to make mining be available to everyone, and provides an even playing field for people looking to issue digital coins without expensive equipment.

mPoW, the magi's proof-of-work (PoW) protocol, in addition to required computational works to be done to deter denial of service attacks, is also a network-dependent rewarding model system. The mPoW rewards participants who solve complicated cryptographical questions not only to validate transactions but also to create new blocks and generate coins. The amout of coins generated are constantly monitored by the mPoW protocol and tuned on the basis of an attraction-repulsion model: 1) incremental rewarding to stimulate network activities during passive mining phase, and 2) decremental rewarding to mitigate redundant mining sources during agressive mining phase. mPoW can effectively govern the magi's network and limit it under a certain scale, enabling the general devices to be capable of mining magi. ++ For details - A network-dependent rewarding system: proof-of-mining

mPoS, the magi's proof-of-stake (PoS) protocol, aims to achieve distributed consensus through operations in addition to mPoW. mPoS is designed such that it rejects potential attacks through accumulating a large amount of coins or offline staking time, either of which leads to security concerns. Similar to mPoW's operation, mPoS is constructed in accordance with the concept of the attraction-repulsion model. Magi hybridizes mPoW with mPoS, and integrate both consensus approaches in order to acquire benefits from the two mechanisms and create a more robust payment system. ++ For details - magi's PoS

FAQ
1. The staking has "Not enough weight", what should I do?
For the regular PoS, "Not enough weight" means insufficient staking time. For Magi's PoS (mPoS), however, the cause can be correlated with the over-time staking. The latter is a typical issue raised by people from time to time. There is only one way to solve this which can be done via resetting staking from scratch: send XMG to another address in the same or another wallet. You may want to use the "Coin control" feature in order to select the input sources. Do not try to stake with a significant amount of XMG that mitigates the weight as well. Once this is done, remaining the wallet running shall gains some staking weights.

Yyyaaayyyy 1K!! Good work. Keep the love flowing

[evok3d]

When i send to an address within the wallet, it doesnt send it at all. It just pays a small fee but it doesnt move the coins. So i resolved by creating a new wallet.dat file and sending it back and forth. If there is a better way to do this, please do let me know.

Moving forward, it seems it is still not staking despite the move. I have mPoS enabled and it has been a few days. Not sure what else to do. I recall it was staking in the past, but now it says "not enough weight" and i have +4K in there...

Any help would be appreciated.

You can move from one address to another within your wallet with

Code:

move <fromaccount> <toaccount> <amount> [minconf=1] [comment]

Nice! Cheers mate. I always wanted to know how to do that

How does 1.4.4.1 change the PoS rules? I'm running the new wallet unlocked with ~1.5k xmg, but it doesn't seem to want to stake like it used to. Do I not have enough coins?  I sent them to myself again a few days ago, and was expecting to see some stake weight by now.

[111magic]

Message received from Cryptopia exchange.
They will look into the wallet updates & if all things are running smooth Cryptopia might keep XMG on the exchange. Lets wait & hope for good news! 😀

A nice celebration is by having issues solved.

[joelao95]

There is a change to block-to-block difficulty adjustment in response to the PoW/PoS rule that leads to relatively large variation. We'll get it sorted out again as mentioned previously with changes in diff algo.

I did check that, but actually, it seems the default is posii = 1. Maybe it gets set to that if the wallet is opened and PoS is enabled (as that's the only thing I did after a fresh install)? Must be do to difficulty variation then, thanks.
