《思想的力量:哲学导论》
427. 马克思主义和自由主义的比较
古典自由主义和传统的马克思主义都来源于启蒙时代(18世纪)的信仰:完美的世界来自自然的秩序。他们都相信未来人类所能享有的自由和幸福都将不断增长;
他们对人类的善都抱有坚定的信念。
十个方面的list进行了对比。两者有不同的认知。
428. 阶级斗争
私有制的登场,社会分成了有产阶级和无产阶级。因为社会关系包含财产关系。
两者敌意无法避免。
资本主义及其后果:根本矛盾,即生产已经社会化了,所有制却没有社会化。工人的异化程度会越来越严重。
资本主义是自我消解的。
429. 马克思主义和共产主义(财产及其他重要物品都属于集体共同所有的社会)
430. 无ZF主义者认为,对于和平、正义、公正、人类能力的充分发展及其他任何值得追求的目标而言,国家都是不必要的。
(Anarchism)是自由主义和马克思主义之外的主要哲学流派
皮埃尔-约瑟夫-普鲁东(1809-1865)就是所谓的无ZF主义之父。他认为一切政治权力机构都阻碍着人类的发展,所以我们应当用另一种社会组织来取代它们。
他认为私有财产的存在导致了社会上的不平等和不正义,由此产生了ZF。

Blockchain:
What happens if the computer running this application has a fault, a power outage, or is hacked? The answer is that the entire system goes down entirely.
For these reasons, businesses and applications have become more and more distributed. Distributed systems typically fall into one of several basic architectures: client–server, three-tier, n-tier or peer-to-peer. Blockchain systems are typically peer-to-peer, so that is what we will discuss here.
The advantages of a distributed system are many, and they are as follows:
- Resiliency: If part of the system fails, the entire system does not fail
- Redundancy: Each part of the system can be built to have backups so that if it fails another copy can be used instead, sometimes instantly
- Parallelism: Work can be divided up efficiently so that many inexpensive computers can be used instead of a single (very expensive) fast computer
