Thisis really clever:
谜的技术——密码学家称之为“安全多方计算”-- works by mimicking a few of the features of bitcoin's decentralized network architecture: It encrypts data by splitting it up into pieces and randomly distributing indecipherable chunks of it to hundreds of computers in the Enigma network known as "nodes."Each node performs calculations on its discrete chunk of information before the user recombines the results to derive an unencrypted answer.Thanks to some mathematical tricks the Enigma creators implemented,这些节点能够集体执行计算机通常执行的各种计算，但除了分配给他们的小数据块之外，没有访问数据的任何其他部分。
To keep track of who owns what data -- and where any given data's pieces have been distributed -- Enigma stores that metadata in the bitcoin blockchain,在比特币经济中，为了防止伪造和欺诈而复制到数千台计算机上的不可原谅的信息记录。
这不是同态加密。But it is really clever.Paperhere.
