ECIP-1043– Fixed DAG limit restriction DAG的最初意图是提供ASIC对采矿协议的抗性，以防止挖矿算力的集中化，从而为矿工公平地分配代币。正在开发的ASIC能够与当前的GPU矿工相同，同时更加节能，DAG在其中就没有做用了，现在只能成为威慑力量分销商对特定应用硬件进行更广泛投资的威慑力量。正因为如此，不断增加的DAG已经开始对长期安全产生负面影响，并成为防止大规模投资矿业发展的反竞争性缺陷。
正如ECIP最初讨论的那样 – ？限制DAG增长＃6 ; 不断增加的DAG最终将达到GPU内存总线速度的硬限制，并迫使GPU变得过时并不会提高安全性。相反，更小的DAG尺寸允许更多GPU的挖掘能力，同时为业余爱好者提供较低的初始进入成本。
The original intent of the DAG was to provide ASIC resistance to the mining protocol in order to prevent centralization of mining distributions and thereby provide for an objectively fair distribution of tokens. As evident by ASICs being developed that are capable of matching current GPU miners while being more energy efficient, the DAG has failed at its task and now only serves as a deterrent to broader investment in application specific hardware by competent distributors. Because of this, the increasing DAG has began to have negative impact on long term security and acts as an anti-competitive bug preventing large scale investment in mining development .
As originally discussed in ECIP-? Limit DAG growth #6; a constantly increasing DAG will eventually reach a hard limit of bus speed on GPU memory and forcing GPU’s into obsolesce does not provide an increase in security. To the contrary, smaller DAG sizes allow more GPU’s the ability to mine while providing a lowered initial entry cost to hobbyist miners.
A 5 year vision of the mining landscape would see a transition from general purpose GPU mining to a broader market of application specific hardware being built by current and supported by a diverse group of manufactures similar to the current GPU market.
