What is the difference between Blockchain and a Database?Generally a database is a collection of data which can be stored and organized using a database management system. The people who have access to the database can view or edit the information stored there. The client-server network architecture is used to implement databases. whereas a blockchain is a growing list of records, called blocks, stored in a distributed system. Each block contains a cryptographic hash of the previous block, timestamp and transaction information. Modification of data is not allowed due to the design of the blockchain. The technology allows decentralized control and eliminates risks of data modification by other parties.
1977 年，塔可夫斯基在爱沙尼亚一个废弃的发电厂开启了《潜行者》的拍摄，这部影片借三个男人穿越“禁区”的神秘旅程，讲述了一个关于欲望和信仰的现代寓言，对信仰、希望和人性的探问贯穿影片。在日记中，塔可夫斯基记录着拍摄的艰辛，也记录着自己对这部作品的期待，他希望用镜头探讨人类的精神救赎。未承想，镜头里的荒凉和危险竟成了对现实的预言。影片的拍摄场地暴露在严重的环境污染下，最终让摄制组付出了惨痛的代价：主演阿纳托利・索洛尼岑、担任副导演的塔可夫斯基的妻子拉丽莎，还有塔可夫斯基本人，在拍摄结束后的几年里先后罹患癌症。病痛的阴影从此萦绕在他的日记里，成为他此后创作中无法回避的底色。。业内人士推荐夫子作为进阶阅读
