披头士的The Beatles Stereo Box Set和The Beatles Mono Box Set有什么区别？

Mono是单声道monobox区块链，原版monobox区块链的母带都是Monomonobox区块链的。

立体声则是後来重新制作的版本。

举一个两者之间不同的例子monobox区块链：《白专》这张专辑的Stereo比Mono播放时间要长一些monobox区块链，其他的专辑也略有不同。

区块链Web3注定无法做大？- dshr

本文是斯坦福大学EE380课程的内容摘要：

无权限区块链 需要 加密货币才能运行，而这种加密货币 需要 投机才能运行。

这就是为什么大规模经济成为分散系统的根本问题？参与必然昂贵，因为是巨大的大规模经济。

规模经济还会他推动分散式系统集中化。因此，试图确保系统分散的努力付出都是徒劳的浪费。

大多数加密货币使用工作证明来实现这些努力，就像我们早期的系统所做的那样。当Cynthia Dwork和Moni Naor于1992年创立它时，这是一个好主意，既简单又有效。但当需要使参与对万亿美元的加密货币来说足够昂贵时，它就有一个不可持续的碳排放的天花板。

如果加密货币投机要继续下去，它需要通过消除工作证明来大幅减少碳足迹。两个主要候选人是时空证明和利益证明。

时空证明试图通过浪费存储而不是计算来使参与变得昂贵。容易上当受骗的人会争相购买硬盘和固态硬盘。存在严重的电子废料处理问题。

利益证明为使参与变得昂贵而带来的成本是损失风险和“利益攸关”的放弃流动性，这是加密货币本身的代占数量。这无疑导致财富向少数人手里集中，先入局者先富，类似传销模型。

还有一系列严重的技术问题。7 多年来，成就卓著的以太坊团队一直在为克服它们做出了值得称赞的努力，望梅止渴地许诺：距离能够从工作证明迁移还有一年多的时间。

与过去七年一样，不超过五个矿池控制了比特币的大部分开采能力，去年11月，两个矿池控制了以太坊的大部分开采。Makarov和Schoar写道：最大的矿池中有六个在中国注册，并与比特币开采硬件的最大生产商Bitmain Techonologies有着密切联系，

集中的不仅仅是采矿池。前10%的矿工控制着90%，只有0.1%（约50名矿工）控制着近50%的采矿能力。这种集中化不仅增加了系统的技术风险，还增加了其法律风险。

不变性是使加密货币犯罪浪潮如此有效的两件事之一。这些系统很脆弱，犯了一个短暂的错误，你的资产是无法挽回的。当一切都要计划下去时，不变性听起来是个好主意，但在现实世界中，错误是不可避免的。让我们举几个最近的例子——Bitfinex为10万美元的交易支付了2300万美元的费用，或指数金融的1900万美元的oopsie，MonoX的3100万美元的oopsie，或Compound的9000万美元的oopsie和随后的670万美元的oopsie，所有这些都让肇事者恳求受益人退还战利品。在Compound的案件中，以最终的加密惩罚威胁其客户，向美国国税局报告他们。到目前为止，12亿美元的DeFi盗窃案，约占所有资金的5%。

由于以太坊和类似的加密货币是编程环境，它们的攻击面比比特币大得多。现在，DeFi和NFT协议在这些环境中作为“智能合同”实施，攻击表面已经进一步扩展。

结论

有三条基本的论点：
