    1. EthereumEthereum is a distributed computer; each node in the network executes some bytecode (hint: Smart Contracts), and then stores the resulting state in a blockchain. Due to the properties of the blockchain representing application state, this results in “applications that run exactly as programmed without any possibility of downtime, censorship, fraud or third party interference”.

      This is a decent little explanation for how smart contracts execute on blockchains. Author missed in "Due to the properties of the blockchain" to say that all nodes must also come to consensus about how the code was executed and therefore "applications that run exactly...". We will later discuss deterministic code execution in relation to this

    1. The great thing about proof is that it requires no belief. Don't believe, verify!

      <big>评:</big><br/><br/>比特币工程师 Lopp 的此番回应是一件很刺激的事情,就像听到尼采说「上帝死了」一样令人激动。在 19 世纪,便有人说:「上帝是一个无用而且很花钱的假设,因此我们不需要他」。200 年后,依然有人扛着如是的观点大旗在卖力宣扬革命。这说明什么?<br/><br/>说明后资本主义时代,人的精神依然处于被压迫、剥削、异化的状态。价值是必须能够被验证的东西,and that's why we have fewer and fewer nice things.

    1. Second, the majority cannot change the rules of Bitcoin. In a sense, they can create new consensus rules, but that would be a hard fork, which requires everyone to upgrade. They’re free to try to convince the rest of the network that their rules are better, but as sovereign individuals, Bitcoin users have no obligation to follow such rules. The power of whom to follow lies entirely with the owner of the node.

      <big>评:</big><br/><br/>What did Jimmy specifically mean when he talked about the group of “Bitcoin users”? And similarly, how to define the gap between the military and the civilian when we talk about some certain power to follow?<br/><br/>可供参考的是,在《人性的弱点》一书里,作者卡耐基反复强调着「人始终只关注自己的利益」。更好的规则?更好的秩序?在利益面前皆为浮云。选择站队的权力确实由个体掌握,但这并不影响到权力是否会被团体以违背个体意志的方式行使。更何况个体意志并不总是「弱者」的代名词,「作恶」也绝非市场垄断者一家之嫌。

    1. visualizations are more than just ‘‘prettypictures’’: rather, precisely in virtue of their bringinginto play oursharedcognitive and aesthetic frame-works as human beings, they thereby catalyze theepistemological – but also aesthetic and therebysocial, if not also political – processes that create ashared intersubjective framework in the first place,one that then makes possible trust-building and asharedsensus communiswithin which the enterpriseof collaborative science may take place

    1. By requiring a lock up period for the DCR to obtain tickets, Decred hopes that only users invested in the long-term growth of the network will be involved in the consensus process. Short-term speculators and day traders of DCR will not be able to participate in consensus or governance without making their holdings illiquid.

    1. The Bottom Line is that you will benefit from using the community group

      Unlike other approaches to learning new PM concepts that span many disciplines and competencies, we help you focus on your strengths and concerns within groups, while developing a holistic solution, that optimally increases your competitive advantage.

      Steps to Creating a Group:

      • Join the Community
      • Create your Own Group
      • Invite Others to Join
    1. All About Community Groups

      This group can help you create your own group.

      • To create a Group, select "New Group"
      • Select a Category that best fits the purpose of your Group.
      • Give your Group a title, a description
      • Make the Group Private or Public.
      • You can also select " Invite Only Group", so only people that are invited can join and see the group.

    1. The problem, said Ward, was that wiki was a relentless consensus engine. And for certain things (e.g. encyclopedias) that might not be a bad thing, but as a way of working it had its drawbacks.

      I'm fascinated by this point.

      This was/is one of the critiques of (Rap) Genius as well: hip as its authoritative voice was, it nonetheless moved toward the encyclopedia. Though the company has since pivoted to allow more individual commentary than encyclopedic exposition--I don't think they've quite worked this out in the UI yet--the original site, and the part I think that is still most compelling was the Wikipedia for rap lyrics.

      But from a pedagogical perspective, that expository mode of analysis was really only one, and perhaps not even the most important, use of collaborative annotation. For my part, I allowed teachers to duplicate texts and create their own versions, instructing their students to annotate however thy wanted them to: authoritatively, discursively, inquisitively, with GIFs.

    1. The Aspen Consensus, in a nutshell, is this: the winners of our age must be challenged to do more good. But never, ever tell them to do less harm.

      Spot on.
