CIP-102: Change PoW mining algorithm

我国对虚拟货币与区块链技术采取了不同的监管立场:一方面,我国对区块链技术和产业发展给予高度重视,区块链被列为“十四五”七大数字经济重点产业之一,希冀为区块链技术和产业发展营造良好的政策环境;另一方面,我国对虚拟货币领域的监管政策层层加码,《2013年通知》的规制目标包括“保障人民币的法定货币地位,防范洗钱风险,维护金融稳定”,《2017年公告》强调“防范化解金融风险”,《2021年通知》则强调“为进一步防范和处置虚拟货币交易炒作风险,切实维护国家安全和社会稳定“。

在风险防范的大基调下,我国公法领域对虚拟货币业务采取了“一刀切”否定式的监管架构,使虚拟货币在公法定性上趋向于事实上的“违禁品”,不受监管机构的正面认可。这两方面的法律政策合力,实质上是在推动“无币区块链”的发展。然而,“无币区块链”的政策导向与区块链产业蓬勃发展之间存在逻辑矛盾。根据区块链技术内部结构的不同,可区分为公有链、私有链和联盟链3种类型。其中,公有链必须依赖共识机制及代币(或通证,即token)经济激励,使缺乏信任基础的参与者由于经济利益产生关联与协作。在区块链生态系统中,通证可以作为通行证、激励、权益证明、价值储存的媒介以及支付清算的手段;没有通证的区块链,很难调动起没有利益关系、彼此之间缺乏信任的大众参与到区块链行业生态系统中来。因此,我国政策推行的“无币区块链”愿景仅在联盟链与私有链中存在可能,无法推动面向公众的公有链的有效发展。公有链是区块链顶尖技术研发的主流,但以代币发行和交易为主要功能的公有链在我国面临合法性困境。

“禁令型”政策可以暂时处置风险,但是从长远来看却有可能扼杀金融创新。以2017年火热的首次代币发行(ICO)为例,首次代币发行在我国兴起源于对普惠金融和中小微创新企业融资的内生需求。我国以中小个人投资者为主的金融市场,缺乏提供与之风险承受能力相匹配的、合适的低门槛投资渠道,致使普通大众难以享受金融投资带来的诸多福利。首次代币发行具有普惠金融的特点和促进包容性增长的功能,体现出传统金融升级换代过程中必然产生的内生需求当下如若不彻底化解高昂融资成本与弱势融资主体资金需求间的矛盾,即使首次代币发行被“扼杀”,各类规避监管“非法”兴起的融资新业态仍会不断衍生。与此同时,不加区分的全面禁令抑制了新兴业态的合规化转型,甚至迫使部分金融科技的从业者由“主动寻求监管”转向“地下”或“出海”发展,从而加剧监管的难度。加粗示例

支持CIP102。

  1. 以太坊挖矿算法被成千上万的矿工和长达7年证明了其可靠性, 能兼容A卡和N卡,让更多矿工能参与进来,功耗也相对树图低,更加成熟可靠

  2. 用户基础大

  3. 当前树图矿工前10名占据了80%的算力,而且币价涨跌对算力影响小,目前算力相对太集中

  4. 能灵活的切换到Ethash,可以证明树图的扩展行和灵活性,能随时势而变,让区块链行业能看到树图敢于改变

当然部分矿工担心修改算法让更多人参与进来动了他们的既得利益,他们反对也很正常,其次切换有可能会出现故障,可能会经历几次修复,但是不影响大局。

众所周知,挖CFX收益是不如挖eth的。
扯什么既得利益…如果改ethash能让我获得和eth一样的收益,我举双脚赞成。But i doubt that.
octopus是吸引我挖CFX的一个因素,我可以用LHR卡和20系显卡获得相对不错的收益。更重要的是,出块速度和容易自建节点让我不需要加入矿池。
如果切换ethash,我的显卡在580和ASIC面前将失去竞争力。和我一样愿意损失一部分收益,换取便捷的小矿工也会增多。
我怀疑届时我的收入将会降低,所以我不喜欢这个提案。
我更希望有一个兼容AMD的,抗ASIC的,对新显卡更公平的新octopus算法,而不是ethash

In my opinion, this idea is just terrible. You propose to make another fork of the ether from an independent network. How will we then be different from thousands of other unknown forks of the ether? what about TPS? Let’s reduce them from unique 3000 to ether 15? ))
So, i am personally with the project from the beginning public mining. I am a miner, holder and i have a personal POS node. And I do all this only in the original cfx network (minenet space). I don’t even use eSpace. I don’t like that eSpace is made on Ethereum technologies. It destroys the uniqueness of cfx. And if cfx will switches to the ether algorithm then the last uniqueness of the project will be destroyed. IMHO

Also… if someone will want to got a more miners in cfx net no need change algo just lite bit up the price on MH then ETH and miners will come immediately )))

The best decision right now is to attract Ethereum miners.
Ensuring network security & Attracting new users and capital :+1::heart:

It would be a good way to market and publicize the cfx network, since it has many positive qualities but they are not yet revealed to the majority of the crypto world.

4袋长老在此,片总现出原形

Pro:

  • High Visibility
  • More miners = higher security
  • Lower DAG Size (something around 5GB would be great)
  • Lower Power Consumption
  • Better profitability for AMD cards

Cons:

  • ASICs
  • Risk to have ETH disadvantages (TPS, Finality Time, Transaction Fees, …)

Neutral:

  • Check if TPS remains the same
  • Check if Finality Time remains the same
  • Tree Graph possible with Ethash

It could be a good idea if you can keep the same TPS and treegraph with ethash but I doubt of it. If you choose this option surely you will have a ratio of the mining farm who will come and have a positive impact on price, because usually price is in correlation with hashrate. The direct consequence will be positive I think but if you can t keep the same TPS and treegraph so the Blockchain will be like a new copy and at term will be without interest. In the same time, I think you will loose your previous community of miners. They can’t compete with farms. I think they will wait price goes up to sell and mine directly an other coin like ergo or flux after ethash activate. There is risk also to loose decentralisation with ethash asics farm. But at term I think if price follow it could be ok. So to conclude if you can keep the technology of treegraph and the same TPS with ethash DO IT, if you can’t DO NOT

Here is a good example what must do Conflux Team in premerge of ETH time, plz check how real experience cryptomining company look on Octopus and Conflux: https://www.prlog.org/12930824-prohashing-announces-the-official-release-of-the-octopus-algorithm.html
Would be good to share own experience of that CIP author in cryptomining. Coz looks like he is a only hear about it.
Want to share my respect to all community members who are share their opinions here and also add my own point of view.

  1. Octopus algo based on Dagger Hashimoto(original name of Ethhash). So here no any problems to reseat on CFX from ETH for “green” miners and some of “red” miners too and support CFX on Octopus;
  2. Same kind of CIPs must include results of hard tests and comparing stats of blockchain network with same setting (block time, Difficulty Adjustment, confirmation amount for full unlock, etc.). Without same it’s not a CIP, just not more than simple discussion thread on forum. Author of CIP are already register here but not active long time after one hot discussion about consensus type of CFX. For sure, miners not be at most discuss any via GitHub as it’s must be when CIP represented to public discussions. And he is not interested in open forum thread for discuss his proposal with community. He not make any tests as must do.
  3. As we all known, after Hydra Hardfork roles of PoW miners in CFX consensus was set on second plan. PoS miners has a extra rights and priority in verification and tx signing. So, it’s a bit joke for now represent CIPs oriented on increasing PoW miners interest and say anything about support and increasing decentralisation.
  4. Most part of ETH miners not a mecenats, but they are make a business, so they are mined ETH coz it’s profitable. Think that with Eth miners here come in same as their hashes investments and CFX price would be pumped and correlated with difficulty pumping not more that weet dreams. Eth early investors who are hold premine control and make Eth market all that years. For now they are not interested in that and go to PoS. Here in CFX early investors are partially sell at full, partially continue received unlocked funds, sell and go out. Team make same. Lol
    So, in that case, if CFX go to Ethash here on short time increase difficulty, old supporters, all who are not go out till moment, go out, coz project drop one of its main exclusive point (at real it’s a last what are CFX not lose from launch till now- octopus algo). Price for sure would be on flat after go down with miners profits gone Eth miners.(need to say that Eth miners has a various numbers of Eth like and not only chains where they can put in their hashes and which are not controlled by centralised PoS layer/chain) And also all of that have a high chance to catch various types of forks (issues) in CFX blockchain/source. At the end you got dump of CFX markets and miners community, community at all. For up interest to CFX better stop dump it and increase centralisation as you do that last 2 years. Coz it’s really funny to see same CIPs from team which are launched under “not same as ETH” slogans. :clown_face:
    Good luck. Cheers to active CFX community. But it’s decreasing every day.

i like this idea, but it would need to be a modified ethash algo, like etchash. because 51% attacks will be likely if its the native ethash

Etc was successfully attacked via 51% attack vector three times, two times in a row. And main reason why they was successful not in mining algo, but simple in low level of hashes on ETC side with token price that make attack profitable. Attack 51% can be done on any of algo.

从技术上来说,是自我否定做法,为了市场倒退不是技术原因,而是生存原因。绥靖政策的由来。。。
改变算法就能让更多人来参与么?难说。。自我意淫,
币价涨就什么都来了,和技术无关,和算法更无关。以太转POS不见得矿工就来树图
再说摒弃自我都没好下场的
这些天观察,改了可能更滥。倒退的技术更没戏。。

If algorithm change is needed it better be Autolykos.
… works good on AMD GPUs, has low power consumption no asics.
The sheer lunacy of updating to ethash is baffling? Has anyone been paid by bitmain here?!
Come on… Updating to ethash after the merge is literally kicking GPUs off the network… How was this proposal even allowed to occur here in the first place is just amazing… That’s my 3 cfx

找对病用对药才,解决通胀的问题才是重点,流通量太多了 。算法改变解决不了通胀问题的

As has been mentioned by many miners, moving to EThash makes no sense. It is not ASIC resistant and the rationale is not sufficient to make such a large change since for any serious miner, changing mining algos/software is trivial.

改个毛。。改了也一样,也没必要,有得必有失,不见得原来以太的算法就是好的,好好的自己的算法二年了挺安全,瞎整啥呢。涨治百病,关建有价格放在哪里,哪怕是腌肉也行。
老计较杀的是哪个品种的猪肉干哈呢。。。
